FUND REPORT

For the six months ended August 31, 2007

MARKET CONDITIONS


Strong fundamental and technical factors supported the municipal bond market
throughout the first four months of the reporting period, helping it to
outperform Treasuries. In July, however, various factors including growing fears
about the contagion effect of the troubled subprime mortgage market, rising
interest rates, and increasing market volatility fueled a flight-to-quality
Treasury market rally. As a result, the performance of the municipal market
waned, particularly the lower-rated, high-yield segment of the market, as
investors fled to the relative safety of high-quality securities.

In the initial months of the reporting period, low prevailing interest rates
drove investor demand for lower-rated, higher-yielding securities, which kept
municipal credit spreads relatively tight. In the last several weeks of the
period, however, as investors became more risk averse, spreads widened across
the credit quality spectrum. The most significant widening occurred in the
lower-rated segments of the market, where spreads on bonds rated BBB and below
(including non-rated bonds) widened by roughly 40 to 50 basis points.

Demand for municipal bonds outpaced the available supply early in the period as
institutional investors and non-traditional buyers such as hedge funds and
arbitrage investors continued to flock to the market. In the latter months, as
market liquidity began to dry up, institutional demand fell off and refunding
activity, which had been robust, virtually halted. Although the supply of
municipal bonds was declining as well, the decrease in demand put significant
pressure on prices at the same time that the Treasury market was rallying. As a
result, municipals underperformed Treasuries and the 30-year
municipal-to-Treasury ratio, which measures the relative attractiveness of these
two sectors, rose from 85 percent to 96 percent by the end of the period,
indicating that municipals underperformed Treasuries while at the same time
becoming cheaper (more attractive) on a relative basis.

Overall, municipal bond yields ended the period higher, but most of the yield
increases occurred in the intermediate to long maturity portion of the yield
curve. Representative yields on 30-year AAA rated municipal bonds rose from 3.97
percent at the start of the period to 4.62 percent by the end of August.
Short-term municipal bond yields, however, were relatively unchanged with yields
on one-year bonds rising from 3.56 percent to 3.60 percent. Accordingly, the
spread between long-term and short-term yields, which began the period at 41
basis points, widened to 102 basis points by the end of the period, causing the
slope of the municipal yield curve to shift from relatively flat to fairly
steep.

PERFORMANCE ANALYSIS


For the six-month period ended August 31, 2007, the net asset value (NAV) of
Morgan Stanley Municipal Income Opportunities Trust II (OIB) decreased from
$9.30 to $8.76 per share. Based on this change plus reinvestment of tax-free
dividends totaling $0.24 per share, the Fund's total NAV return was -3.28
percent. OIB's value on the New York Stock Exchange (NYSE) moved from $9.14 to
$8.44 per share during the same period. Based on this change plus reinvestment
of dividends, the Fund's total market return was -5.18 percent. OIB's NYSE
market price was at a 3.65 percent discount to its NAV. During the fiscal
period, the Fund purchased and retired 22,200 shares of common stock at a
weighted average market discount of 5.31 percent. Past performance is no
guarantee of future results.

Monthly dividends for the third quarter of 2007, declared in June, were
unchanged at $0.040 per share. The dividend reflects the current level of the
Fund's net investment income. OIB's level of undistributed net investment income
was $0.082 per share on August 31, 2007 versus $0.083 per share six months
earlier.(1) All holdings were accruing interest at the end of the reporting
period.

Our anticipation of higher interest rates led us to maintain the Fund's lower
option-adjusted duration* through June. In July and August we began to gradually
lengthen the duration to a more neutral stance. This defensive interest-rate
positioning was additive to performance for the overall period as interest rates
generally rose.

The Fund invests primarily in higher yielding municipal bonds. During the
period, we slightly increased the Fund's exposure to these below
investment-grade or non-rated issues, which represented more than two-thirds of
assets by period end. This credit quality profile had a positive impact on
performance for much of the period as the lower-rated segment of the market,
boosted by strong demand and a limited supply, outperformed the investment-grade
sector. In the last weeks of the period, however, the performance of lower-rated
bonds waned and the sector underperformed higher-quality securities.

Another boost to the Fund's performance was its pre-refunded holdings,
representing over 6 percent of net assets as of the end of the reporting period.
These securities benefited from their short maturities in that they did not
experience the sell-off that longer maturity bonds did when yields on the long
end of the curve rose. Conversely, the Fund's exposure to the single family
housing and tobacco sectors detracted from overall performance. Spreads in these
sectors widened considerably during the period, dampening their performance.

Overall, the Fund's investments remained well-diversified across a broad range
of sectors. As of the end of the period, sector exposure was relatively
unchanged from six months earlier, with life care, hospital, and special tax
districts representing the Fund's largest sector weightings.

OIB's procedure for reinvesting all dividends and distributions in common shares
is through purchases in the open market. This method helps support the market
value of the Fund's shares. In addition, we would like to remind you that the
Trustees have approved a procedure whereby the Fund may, when appropriate,
purchase shares in the open market or in privately negotiated transactions at a
price not above market value or net asset value, whichever is lower at the time
of purchase.

* A measure of the sensitivity of a bond's price to changes in interest rates,
expressed in years. Each year of duration represents an expected 1 percent
change in the price of a bond for every 1 percent change in interest rates. The
longer a bond's duration, the greater the effect of interest-rate movements on
its price. Typically, funds with shorter durations perform better in
rising-interest-rate environments, while funds with longer durations perform
better when rates decline.

INVESTMENT ADVISORY AGREEMENT APPROVAL

NATURE, EXTENT AND QUALITY OF SERVICES


The Board reviewed and considered the nature and extent of the investment
advisory services provided by the Investment Adviser under the Advisory
Agreement, including portfolio management, investment research and fixed income
securities trading. The Board also reviewed and considered the nature and extent
of the non-advisory, administrative services provided by the Fund's
Administrator under the Administration Agreement, including accounting,
clerical, bookkeeping, compliance, business management and planning, and the
provision of supplies, office space and utilities at the Investment Adviser's
expense. (The Investment Adviser and the Administrator together are referred to
as the "Adviser" and the Advisory and Administration Agreements together are
referred to as the "Management Agreement.") The Board also compared the nature
of the services provided by the Adviser with similar services provided by
non-affiliated advisers as reported to the Board by Lipper Inc. ("Lipper").

The Board reviewed and considered the qualifications of the portfolio managers,
the senior administrative managers and other key personnel of the Adviser who
provide the advisory and administrative services to the Fund. The Board
determined that the Adviser's portfolio managers and key personnel are well
qualified by education and/or training and experience to perform the services in
an efficient and professional manner. The Board concluded that the nature and
extent of the advisory and administrative services provided were necessary and
appropriate for the conduct of the business and investment activities of the
Fund. The Board also concluded that the overall quality of the advisory and
administrative services was satisfactory.

PERFORMANCE RELATIVE TO COMPARABLE FUNDS MANAGED BY OTHER ADVISERS


On a regular basis, the Board reviews the performance of all funds in the Morgan
Stanley Fund Complex, including the Fund, compared to their peers, paying
specific attention to the underperforming funds. In addition, the Board
specifically reviewed the Fund's performance for the one-, three- and five-year
periods ended November 30, 2006, as shown in a report provided by Lipper (the
"Lipper Report"), compared to the performance of comparable funds selected by
Lipper (the "performance peer group"). The Board also discussed with the Adviser
the performance goals and the actual results achieved in managing the Fund. The
Board concluded that the Fund's performance was competitive with that of its
performance peer group.

FEES RELATIVE TO OTHER PROPRIETARY FUNDS MANAGED BY THE ADVISER WITH COMPARABLE
INVESTMENT STRATEGIES


The Board reviewed the advisory and administrative fee (together, the
"management fee") rate paid by the Fund under the Management Agreement. The
Board noted that the management fee rate was comparable to

                                                                               7


the management fee rates charged by the Adviser to other proprietary funds it
manages with investment strategies comparable to those of the Fund.

FEES AND EXPENSES RELATIVE TO COMPARABLE FUNDS MANAGED BY OTHER ADVISERS


The Board reviewed the management fee rate and total expense ratio of the Fund
as compared to the average management fee rate and average total expense ratio
for funds, selected by Lipper (the "expense peer group"), managed by other
advisers with investment strategies comparable to those of the Fund, as shown in
the Lipper Report. The Board concluded that the Fund's management fee rate and
total expense ratio were competitive with those of its expense peer group.

BREAKPOINTS AND ECONOMIES OF SCALE


The Board reviewed the structure of the Fund's management fee schedule under the
Management Agreement and noted that it does not include any breakpoints. The
Board considered that the Fund is a closed-end fund and, therefore, that the
Fund's assets are not likely to grow with new sales or grow significantly as a
result of capital appreciation. The Board concluded that economies of scale for
this Fund were not a factor that needed to be considered at the present time.

PROFITABILITY OF THE ADVISER AND AFFILIATES


The Board considered information concerning the costs incurred and profits
realized by the Adviser and affiliates during the last year from their
relationship with the Fund and during the last two years from their relationship
with the Morgan Stanley Fund Complex and reviewed with the Adviser the cost
allocation methodology used to determine the profitability of the Adviser and
affiliates. Based on its review of the information it received, the Board
concluded that the profits earned by the Adviser and affiliates were not
excessive in light of the advisory, administrative and other services provided
to the Fund.

FALL-OUT BENEFITS


The Board considered so-called "fall-out benefits" derived by the Adviser and
affiliates from their relationship with the Fund and the Morgan Stanley Fund
Complex, such as commissions on the purchase and sale of Fund shares and "float"
benefits derived from handling of checks for purchases and sales of Fund shares,
through a broker-dealer affiliate of the Adviser. The Board concluded that the
commissions were competitive with those of other broker-dealers and the float
benefits were relatively small.

8


SOFT DOLLAR BENEFITS


The Board considered whether the Adviser realizes any benefits from commissions
paid to brokers who execute securities transactions for the Fund ("soft
dollars"). The Board noted that the Fund invests only in fixed income
securities, which do not generate soft dollars.

ADVISER FINANCIALLY SOUND AND FINANCIALLY CAPABLE OF MEETING THE FUND'S NEEDS


The Board considered whether the Adviser is financially sound and has the
resources necessary to perform its obligations under the Management Agreement.
The Board concluded that the Adviser has the financial resources necessary to
fulfill its obligations under the Management Agreement.

HISTORICAL RELATIONSHIP BETWEEN THE FUND AND THE ADVISER


The Board also reviewed and considered the historical relationship between the
Fund and the Adviser, including the organizational structure of the Adviser, the
policies and procedures formulated and adopted by the Adviser for managing the
Fund's operations and the Board's confidence in the competence and integrity of
the senior managers and key personnel of the Adviser. The Board concluded that
it is beneficial for the Fund to continue its relationship with the Adviser.

OTHER FACTORS AND CURRENT TRENDS


The Board considered the controls and procedures adopted and implemented by the
Adviser and monitored by the Fund's Chief Compliance Officer and concluded that
the conduct of business by the Adviser indicates a good faith effort on its part
to adhere to high ethical standards in the conduct of the Fund's business.

GENERAL CONCLUSION


On April 25, 2007, after considering and weighing all of the above factors, the
Board concluded that it would be in the best interest of the Fund and its
shareholders to approve renewal of the Management Agreement for another year
until April 30, 2008. On June 20, 2007, the Board again considered and weighed
all of the above factors and concluded that it would be in the best interest of
the Fund and its shareholders to approve renewal of the Management Agreement to
continue until June 30, 2008.

                                                                               9

Morgan Stanley Municipal Income Opportunities Trust II
NOTES TO FINANCIAL STATEMENTS - AUGUST 31, 2007 (UNAUDITED)

1. Organization and Accounting Policies

Morgan Stanley Municipal Income Opportunities Trust II (the "Fund") is
registered under the Investment Company Act of 1940, as amended, as a
diversified, closed-end management investment company. The Fund's investment
objective is to provide current income exempt from federal income tax. The Fund
was organized as a Massachusetts business trust on March 8, 1989 and commenced
operations on June 30, 1989.

The following is a summary of significant accounting policies:

A. Valuation of Investments -- (1) portfolio securities are valued by an outside
independent pricing service approved by the Trustees. The pricing service uses
both a computerized grid matrix of tax-exempt securities and evaluations by its
staff, in each case based on information concerning market transactions and
quotations from dealers which reflect the mean between the last reported bid and
asked price. The portfolio securities are thus valued by reference to a
combination of transactions and quotations for the same or other securities
believed to be comparable in quality, coupon, maturity, type of issue, call
provisions, trading characteristics and other features deemed to be relevant.
The Trustees believe that timely and reliable market quotations are generally
not readily available for purposes of valuing tax-exempt securities and that the
valuations supplied by the pricing service are more likely to approximate the
fair value of such securities; (2) futures are valued at the latest sale price
on the commodities exchange on which they trade unless it is determined that
such price does not reflect their market value, in which case they will be
valued at their fair value as determined in good faith under procedures
established by and under the supervision of the Trustees; (3) Interest rate
swaps are marked-to-market daily based upon quotations from market makers and
the change, if any, is recorded as unrealized appreciation or depreciation in
the Statement of Operations; (4) Investments in open-end mutual funds, including
the Morgan Stanley Institutional Liquidity Funds, are valued at the net asset
value as of the close of each business day; and (5) short-term debt securities
having a maturity date of more than sixty days at time of purchase are valued on
a mark-to-market basis until sixty days prior to maturity and thereafter at
amortized cost based on their value on the 61st day. Short-term debt securities
having a maturity date of sixty days or less at the time of purchase are valued
at amortized cost.

B. Accounting for Investments -- Security transactions are accounted for on the
trade date (date the order to buy or sell is executed). Realized gains and
losses on security transactions are determined by the identified cost method.
Discounts are accreted and premiums are amortized over the life of the
respective securities and are included in interest income. Interest income is
accrued daily except where collection is not expected.

Morgan Stanley Municipal Income Opportunities Trust II
NOTES TO FINANCIAL STATEMENTS - AUGUST 31, 2007 (UNAUDITED) continued

C. Futures Contracts -- A futures contract is an agreement between two parties
to buy and sell financial instruments or contracts based on financial indices at
a set price on a future date. Upon entering into such a contract, the Fund is
required to pledge to the broker cash, U.S. Government securities or other
liquid portfolio securities equal to the minimum initial margin requirements of
the applicable futures exchange. Pursuant to the contract, the Fund agrees to
receive from or pay to the broker an amount of cash equal to the daily
fluctuation in the value of the contract. Such receipts or payments known as
variation margin are recorded by the Fund as unrealized gains and losses. Upon
closing of the contract, the Fund realizes a gain or loss equal to the
difference between the value of the contract at the time it was opened and the
value at the time it was closed.

D. Floating Rate Note Obligations Related to Securities Held -- The Fund enters
into transactions in which it transfers to Dealer Trusts ("Dealer Trusts"),
fixed rate bonds in exchange for cash and residual interests in the Dealer
Trusts' assets and cash flows, which are in the form of inverse floating rate
investments. The Dealer Trusts fund the purchases of the fixed rate bonds by
issuing floating rate notes to third parties and allowing the Fund to retain
residual interest in the bonds. The Fund enters into shortfall agreements with
the Dealer Trusts which commit the Fund to pay the Dealer Trusts, in certain
circumstances, the difference between the liquidation value of the fixed rate
bonds held by the Dealer Trusts and the liquidation value of the floating rate
notes held by third parties, as well as any shortfalls in interest cash flows.
The residual interests held by the Fund (inverse floating rate investments)
include the right of the Fund (1) to cause the holders of the floating rate
notes to tender their notes at par at the next interest rate reset date, and (2)
to transfer the municipal bond from the Dealer Trusts to the Fund, thereby
collapsing the Dealer Trusts. The Fund accounts for the transfer of bonds to the
Dealer Trusts as secured borrowings, with the securities transferred remaining
in the Fund's investment assets, and the related floating rate notes reflected
as Fund liabilities under the caption "floating rate note obligations" on the
Statement of Assets and Liabilities. The Fund records the interest income from
the fixed rate bonds under the caption "Interest Income" and records the
expenses related to floating rate note obligations and any administrative
expenses of the Dealer Trusts under the caption "Interest and residual trust
expenses" in the Fund's Statement of Operations. The notes issued by the Dealer
Trusts have interest rates that reset weekly and the floating rate note holders
have the option to tender their notes to the Dealer Trusts for redemption at par
at each reset date. At August 31, 2007, Fund investments with a value of
$10,962,829 are held by the Dealer Trusts and serve as collateral for the
$8,665,000 in floating rate note obligations outstanding at that date.
Contractual maturities of the floating rate note obligations and interest rates
in effect at August 31, 2007 are presented in the Portfolio of Investments.

                                                                              23

NOTES TO FINANCIAL STATEMENTS - AUGUST 31, 2007 (UNAUDITED) continued

E. Interest Rate Swaps -- Interest rate swaps involve the exchange of
commitments to pay and receive interest based on a notional principal amount.
Net periodic interest payments to be received or paid are accrued daily and are
recorded as realized gains or losses in the Statement of Operations.

F. Federal Income Tax Policy -- It is the Fund's policy to comply with the
requirements of Subchapter M of the Internal Revenue Code applicable to
regulated investment companies and to distribute substantially all of its
taxable and nontaxable income to its shareholders. Therefore, no provision for
federal income taxes is required. The Fund files tax returns with the U.S.
Internal Revenue Service and various states. Generally, the tax authorities can
examine all tax returns filed for the last three years. If applicable, the Fund
recognizes interest accrued related to unrecognized tax benefits in interest
expense and penalties in other expenses in the Statement of Operations. The Fund
adopted the provisions of the Financial Accounting Standards Board's (FSAB)
Interpretation number 48 Accounting for Uncertainty in Income Taxes, on June 30,
2007. As of August 31, 2007, this did not result in an impact to the Fund's
financial statements.

G. Dividends and Distributions to Shareholders -- Dividends and distributions to
shareholders are recorded on the ex-dividend date.

H. Use of Estimates -- The preparation of financial statements in accordance
with generally accepted accounting principles requires management to make
estimates and assumptions that affect the reported amounts and disclosures.
Actual results could differ from those estimates.

2. Investment Advisory/Administration Agreements

Pursuant to an Investment Advisory Agreement with Morgan Stanley Investment
Advisors Inc. (the "Investment Adviser"), the Fund pays the Investment Adviser
an advisory fee, calculated weekly and payable monthly, by applying the annual
rate of 0.50% to the Fund's weekly net assets.

Pursuant to an Administration Agreement with Morgan Stanley Services Company
Inc. (the "Administrator"), an affiliate of the Investment Adviser, the Fund
pays an administration fee, calculated weekly and payable monthly, by applying
the annual rate of 0.08% to the Fund's weekly net assets.

3. Security Transactions and Transactions with Affiliates

The Fund invests in Morgan Stanley Institutional Liquidity Tax-Exempt
Portfolio -- Institutional Class, an open-end management investment company
managed by the Investment Adviser. Investment advisory fees paid by the Fund are
reduced by an amount equal to the advisory and administrative services fees paid
by Morgan Stanley Institutional Liquidity Tax-Exempt Portfolio -- Institutional
Class

Morgan Stanley Municipal Income Opportunities Trust II
NOTES TO FINANCIAL STATEMENTS - AUGUST 31, 2007 (UNAUDITED) continued

with respect to assets invested by the Fund in Morgan Stanley Institutional
Liquidity Tax-Exempt Portfolio -- Institutional Class. For the six months ended
August 31, 2007, advisory fees paid were reduced by $160 relating to the Fund's
investment in Morgan Stanley Institutional Liquidity Tax-Exempt
Portfolio -- Institutional Class. Income distributions earned by the Fund are
recorded as dividends from affiliate in the Statement of Operations and totaled
$14,378. During the six months ended August 31, 2007, cost of purchases and
sales of Morgan Stanley Institutional Liquidity Tax-Exempt
Portfolio -- Institutional Class were $13,896,553 and $10,095,610, respectively.

The cost of purchases and proceeds from sales of portfolio securities, excluding
short-term investments, for the six months ended August 31, 2007 aggregated
$26,355,662 and $19,325,134, respectively.

Morgan Stanley Trust, an affiliate of the Investment Adviser and Administrator,
is the Fund's transfer agent.

The Fund has an unfunded noncontributory defined benefit pension plan covering
certain independent Trustees of the Fund who will have served as independent
Trustees for at least five years at the time of retirement. Benefits under this
plan are based on factors which include years of service and compensation. The
Trustees voted to close the plan to new participants and eliminate the future
benefits growth due to increases to compensation after July 31, 2003. Aggregate
pension costs for the six months ended August 31, 2007, included in Trustees'
fees and expenses in the Statement of Operations amounted to $2,992. At August
31, 2007, the Fund had an accrued pension liability of $61,620 which is included
in accrued expenses in the Statement of Assets and Liabilities.

The Fund has an unfunded Deferred Compensation Plan (the "Compensation Plan")
which allows each independent Trustee to defer payment of all, or a portion, of
the fees he or she receives for serving on the Board of Trustees. Each eligible
Trustee generally may elect to have the deferred amounts credited with a return
equal to the total return on one or more of the Morgan Stanley funds that are
offered as investment options under the Compensation Plan.
Appreciation/depreciation and distributions received from these investments are
recorded with an offsetting increase/decrease in the deferred compensation
obligation and do not affect the net asset value of the Fund.

                                                                              25

6. Purposes of and Risks Relating to Certain Financial Instruments

The Fund may invest a portion of its assets in inverse floating rate
instruments, either through outright purchases of inverse floating rate
securities or through the transfer of bonds to a Dealer Trust in exchange for
cash and residual interests in the Dealer Trust. These investments are typically
used by the Fund in seeking to enhance the yield of the portfolio. These
instruments typically involve greater risks than a fixed rate municipal bond. In
particular, these instruments are acquired through leverage or may have leverage
embedded in them and therefore involve many of the risks associated with
leverage. Leverage is a speculative technique that may expose the Fund to
greater risk and increased costs. Leverage may cause the Fund's net asset value
to be more volatile than if it had not been leveraged because leverage tends to
magnify the effect of any increases or decreases in the value of the Fund's
portfolio securities. The use of leverage may also cause the Fund to liquidate
portfolio positions when it may not be advantageous to do so in order to satisfy
its obligations with respect to inverse floating rate instruments.

26


Morgan Stanley Municipal Income Opportunities Trust II
NOTES TO FINANCIAL STATEMENTS - AUGUST 31, 2007 (UNAUDITED) continued

To hedge against adverse interest rate changes, the Fund may invest in financial
futures contracts or municipal bond index futures contracts ("futures
contracts").

These futures contracts involve elements of market risk in excess of the amount
reflected in the Statement of Assets and Liabilities. The Fund bears the risk of
an unfavorable change in the value of the underlying securities. Risks may also
arise upon entering into these contracts from the potential inability of the
counterparties to meet the terms of their contracts.

The Fund may enter into interest rate swaps and may purchase or sell interest
rate caps, floors and collars. The Fund expects to enter into these transactions
primarily to manage interest rate risk, hedge portfolio positions and preserve a
return or spread on a particular investment or portion of its portfolio. The
Fund may also enter into these transactions to protect against any increase in
the price of securities the Fund anticipates purchasing at a later date.
Interest rate swap transactions are subject to market risk, risk of default by
the other party to the transaction, risk of imperfect correlation and manager
risk. Such risks may exceed the related amounts shown in the Statement of Assets
and Liabilities.

7. Federal Income Tax Status

The amount of dividends and distributions from net investment income and net
realized capital gains are determined in accordance with federal income tax
regulations which may differ from generally accepted accounting principles.
These "book/tax" differences are either considered temporary or permanent in
nature. To the extent these differences are permanent in nature, such amounts
are reclassified within the capital accounts based on their federal tax-basis
treatment; temporary differences do not require reclassification. Dividends and
distributions which exceed net investment income and net realized capital gains
for tax purposes are reported as distributions of paid-in-capital.

As of February 28, 2007, the Fund had a net capital loss carryforward of
$5,355,116 of which $3,882,417 will expire on February 28, 2011 and $1,472,699
will expire on February 28, 2013 to offset future capital gains to the extent
provided by regulations.

As of February 28, 2007, the Fund had temporary book/tax differences primarily
attributable to book amortization of discounts on debt securities and
mark-to-market of open futures contracts.

8. Expense Offset

The expense offset represents a reduction of the fees and expenses for interest
earned on cash balances maintained by the Fund with the transfer agent and
custodian.

                                                                              27

9. Accounting Pronouncement

In September 2006, Statement of Financial Accounting Standards No. 157, Fair
Value Measurements (SFAS 157), was issued and is effective for fiscal years
beginning after November 15, 2007. SFAS 157 defines fair value, establishes a
framework for measuring fair value and expands disclosures about fair value
measurements. Management is currently evaluating the impact the adoption of SFAS
157 will have on the Fund's financial statement disclosures.
