FUND REPORT For the year ended March 31, 2005 MARKET CONDITIONS During the 12 months ended March 31, 2005, growth in consumer spending and business investment helped the U.S. economy expand at a solid pace. Interest rates moved higher at the beginning of the period after the April release of the March 2004 employment report was significantly stronger than expected and included upward revisions. The bond market also began to focus on global commodity supply pressures, and specifically, on the rapid climb in oil prices. In the summer, uncertainty over the ability of the economy to sustain its recovery caused yields to decline on longer maturity bonds. This environment persisted through the fall and early winter. Renewed signs of economic strength and a pick-up in inflation moved interest rates higher during the final quarter of the Fund's fiscal year. During the period, investors' attention also focused on the Federal Open Market Committee's (the "Fed") policy shift, which began in June 2004 with the first of seven consecutive 25 basis point rate hikes. These increases took the federal funds target rate to 2.75 percent by the end of March 2005, and represented a reversal of the Fed's rate reductions between January 2001 and June 2003. At the end of the period, the forward yield curve reflected a widespread view that the Fed would continue its current pace of rate increases. Against this setting, municipal bond yields peaked in June, moved lower through the fall, and rose as the fiscal year ended. Lower-quality municipal bonds performed strongly in this environment and the yield spread between investment grade bonds and lower-quality issues narrowed significantly. Total municipal underwriting volume in calendar 2004 was $359 billion, only 7 percent below 2003's record level. For the March 2005 quarter, volume increased 11 percent compared to the same period one year earlier. Issuers in California, Texas, New York, Florida and New Jersey accounted for 44 percent of the total. On the demand side, the municipal-to-Treasury yield ratio, which gauges relative performance between the two markets, remained attractive for tax-exempts. As a result, fixed income investors that normally focus on taxable sectors (such as insurance companies and hedge funds) supported municipals by "crossing over" to purchase bonds. However, retail investors continued to experience rate shock from the absolute level of rates and largely remained on the sidelines. PERFORMANCE ANALYSIS For the 12-month period ended March 31, 2005, the net asset value (NAV) of the Morgan Stanley Municipal Income Opportunities Trust III (OIC) increased from $9.39 to $9.51 per share. Based on this change plus reinvestment of distributions totaling $0.531549 per share the Fund's total NAV return was 7.85 percent. The Fund's value on the New York Stock Exchange (NYSE) moved from $8.92 to $8.27 per share during the same period. Based on this change plus reinvestment of distributions, the Fund's total market return was -1.27 percent. On March 31, 2005, the Fund's NYSE market price was at a 13.04 percent discount to its NAV. During the 12-month period ended March 31, 2005, the Fund purchased and retired 2 233,495 shares of common stock at a weighted average market discount of 10.25 percent. Past performance is no guarantee of future results. Beginning in the fourth quarter of 2004, monthly dividends were reduced from $0.045 per share to $0.0425 per share. The dividend reflects the current level of the Fund's net investment income. The Fund's level of undistributed net investment income was $0.10 per share on March 31, 2005, which remained unchanged from 12 months earlier.* The Fund is a non-leveraged closed-end fund that has historically benefited by investing in better-than-average quality issues within the high yield sector of the municipal market. Currently, nearly 60 percent of the portfolio is invested in non-rated issues. The Fund's net assets of $84 million were diversified across 82 credits in 11 sectors. The Fund's procedure for reinvesting all dividends and distributions on 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 investors 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 NAV, whichever is lower at the time of purchase. - ---------------------------------------------------- PERFORMANCE DATA QUOTED REPRESENTS PAST PERFORMANCE, WHICH IS NO GUARANTEE OF FUTURE RESULTS, AND CURRENT PERFORMANCE MAY BE LOWER OR HIGHER THAN THE FIGURES SHOWN.

Organization and Accounting Policies Morgan Stanley Municipal Income Opportunities Trust III (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 a high level of current income which is exempt from federal income tax. The Fund was organized as a Massachusetts business trust on February 20, 1990 and commenced operations on April 30, 1990. 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; and (3) 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. Interest income is accrued daily except where collection is not expected. 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 16 Morgan Stanley Municipal Income Opportunities Trust III NOTES TO FINANCIAL STATEMENTS - MARCH 31, 2005 continued 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. Federal Income Tax Policy -- It is the Fund's policy to comply with the requirements of the Internal Revenue Code applicable to regulated investment companies and to distribute substantially all of its taxable and nontaxable income to its shareholders. Accordingly, no federal income tax provision is required. E. Dividends and Distributions to Shareholders -- Dividends and distributions to shareholders are recorded on the ex-dividend date. F. 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. Prior to November 1, 2004, the annual rate was 0.30%. 3. Security Transactions and Transactions with Affiliates The cost of purchases and proceeds from sales of portfolio securities, excluding short-term investments, for the year ended March 31, 2005 aggregated $13,885,005 and $15,397,631, respectively. Included in the aforementioned transactions are purchases and sales of $5,795,997 and $2,037,950, respectively, with other Morgan Stanley funds including a net realized gain of $57,811. Morgan Stanley Trust, an affiliate of the Investment Adviser and Administrator, is the Fund's transfer agent. At March 31, 2005, the Fund had transfer agent fees and expenses payable of approximately $7,000. 17 Morgan Stanley Municipal Income Opportunities Trust III NOTES TO FINANCIAL STATEMENTS - MARCH 31, 2005 continued 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. Aggregate pension costs for the year ended March 31, 2005 included in Trustees' fees and expenses in the Statement of Operations amounted to $7,272. At March 31, 2005, the Fund had an accrued pension liability of $59,833 which is included in accrued expenses in the Statement of Assets and Liabilities. On December 2, 2003, 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. 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 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. 4. Shares of Beneficial Interest Transactions in shares of beneficial interest were as follows: <Table> <Caption> CAPITAL PAID IN PAR VALUE EXCESS OF SHARES OF SHARES PAR VALUE --------- --------- ----------- Balance, March 31, 2003..................................... 9,279,573 $92,796 $87,900,811 Treasury shares purchased and retired (weighted average discount 6.08%)*..........................................

Dividends On March 29, 2005, the Fund declared the following dividends from net investment income: <Table> <Caption> AMOUNT RECORD PAYABLE PER SHARE DATE DATE - --------- --------------- --------------- $0.0425 April 8, 2005 April 22, 2005 $0.0425 May 6, 2005 May 20, 2005 $0.0425 June 3, 2005 June 17, 2005 </Table> 6. Expense Offset The expense offset represents a reduction of the custodian fees for earnings on cash balances maintained by the Fund. 7. Risks Relating to Certain Financial Instruments The Fund may invest a portion of its assets in residual interest bonds, which are inverse floating rate municipal obligations. The prices of these securities are subject to greater market fluctuations during periods of changing prevailing interest rates than are comparable fixed rate obligations. 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. 8. 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. 19 Morgan Stanley Municipal Income Opportunities Trust III NOTES TO FINANCIAL STATEMENTS - MARCH 31, 2005 continued The tax character of distributions paid was as follows: <Table> <Caption> FOR THE YEAR FOR THE YEAR ENDED ENDED MARCH 31, 2005 MARCH 31, 2004 -------------- -------------- Tax-exempt income........................................... $ 4,731,105 $5,107,395 Ordinary income............................................. 58,814 -- ----------- ---------- Total distributions......................................... $ 4,789,919 $5,107,395 =========== ========== </Table> As of March 31, 2005, the tax-basis components of accumulated losses were as follows: <Table> Undistributed tax-exempt income............................. $ 824,450 Undistributed long-term gains............................... -- ----------- Net accumulated earnings.................................... 824,450 Capital loss carryforward*..................................

As of March 31, 2005, the Fund had temporary book/tax differences primarily attributable to book amortization of discounts on debt securities and permanent book/tax differences primarily attributable to tax adjustments on debt securities sold by the Fund. To reflect reclassifications arising from the permanent differences, paid-in-capital was charged $60, accumulated net realized loss was charged $278 and accumulated undistributed net investment income was credited $338. 20 Morgan Stanley Municipal Income Opportunities Trust III FINANCIAL HIGHLIGHTS Selected ratios and per share data for a share of beneficial interest outstanding throughout each period: <Table> <Caption> FOR THE YEAR ENDED MARCH 31 ---------------------------------------------------------------- 2005 2004 2003 2002 2001 -------- -------- -------- -------- -------- Selected Per Share Data: Net asset value, beginning of period....................... $9.39 $9.33 $9.32 $9.48 $9.34 ----- ----- ----- ----- ----- Income (loss) from investment operations: Net investment income*................................. 0.53 0.52 0.56 0.57 0.57 Net realized and unrealized gain (loss)................ 0.10 0.09 0.01 (0.12) 0.11 ----- ----- ----- ----- ----- Total income from investment operations.................... 0.63 0.61 0.57 0.45 0.68 ----- ----- ----- ----- ----- Less dividends and distributions from: Net investment income..................................

These financial statements and financial highlights are the responsibility of the Fund's management. Our responsibility is to express an opinion on these financial statements and financial highlights based on our audits. We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements and financial highlights are free of material misstatement. The Fund is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. Our audits included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Fund's internal control over financial reporting. Accordingly, we express no such opinion. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. Our procedures included confirmation of securities owned as of March 31, 2005, by correspondence with the custodian. We believe that our audits provide a reasonable basis for our opinion. In our opinion, the financial statements and financial highlights referred to above present fairly, in all material respects, the financial position of Morgan Stanley Municipal Income Opportunities Trust III as of March 31, 2005, the results of its operations for the year then ended, the changes in its net assets for each of the two years in the period then ended, and the financial highlights for each of the five years in the period then ended, in conformity with accounting principles generally accepted in the United States of America.

STATEMENT OF PRINCIPLES The Audit Committee of the Board is required to review and, in its sole discretion, pre-approve all Covered Services to be provided by the Independent Auditors to the Fund and Covered Entities in order to assure that services performed by the Independent Auditors do not impair the auditor's independence from the Fund. The SEC has issued rules specifying the types of services that an independent auditor may not provide to its audit client, as well as the audit committee's administration of the engagement of the independent auditor. The SEC's rules establish two different approaches to pre-approving services, which the SEC considers to be equally valid. Proposed services either: may be pre-approved without consideration of specific case-by-case services by the Audit Committee ("general pre-approval"); or require the specific pre-approval of the Audit Committee or its delegate ("specific pre-approval"). The Audit Committee believes that the combination of these two approaches in this Policy will result in an effective and efficient procedure to pre-approve services performed by the Independent Auditors. As set forth in this Policy, unless a type of service has received general pre-approval, it will require specific pre-approval by the Audit Committee (or by any member of the Audit Committee to which pre-approval authority has been delegated) if it is to be provided by the Independent Auditors. Any proposed services exceeding pre-approved cost levels or budgeted amounts will also require specific pre-approval by the Audit Committee. The appendices to this Policy describe the Audit, Audit-related, Tax and All Other services that have the general pre-approval of the Audit Committee. The term of any general pre-approval is 12 months from the date of pre-approval, unless the Audit Committee considers and provides a different period and states otherwise. The Audit Committee will annually review and pre-approve the services that may be provided by the Independent Auditors without obtaining specific pre-approval from the Audit Committee. The Audit Committee will add to or subtract from the list of general pre-approved services from time to time, based on subsequent determinations. - ---------- 1 This Audit Committee Audit and Non-Audit Services Pre-Approval Policy and Procedures (the "Policy"), adopted as of the date above, supersedes and replaces all prior versions that may have been adopted from time to time. 3 The purpose of this Policy is to set forth the policy and procedures by which the Audit Committee intends to fulfill its responsibilities. It does not delegate the Audit Committee's responsibilities to pre-approve services performed by the Independent Auditors to management. The Fund's Independent Auditors have reviewed this Policy and believes that implementation of the Policy will not adversely affect the Independent Auditors' independence. 2. DELEGATION As provided in the Act and the SEC's rules, the Audit Committee may delegate either type of pre-approval authority to one or more of its members. The member to whom such authority is delegated must report, for informational purposes only, any pre-approval decisions to the Audit Committee at its next scheduled meeting. 3. AUDIT SERVICES The annual Audit services engagement terms and fees are subject to the specific pre-approval of the Audit Committee. Audit services include the annual financial statement audit and other procedures required to be performed by the Independent Auditors to be able to form an opinion on the Fund's financial statements. These other procedures include information systems and procedural reviews and testing performed in order to understand and place reliance on the systems of internal control, and consultations relating to the audit. The Audit Committee will approve, if necessary, any changes in terms, conditions and fees resulting from changes in audit scope, Fund structure or other items. In addition to the annual Audit services engagement approved by the Audit Committee, the Audit Committee may grant general pre-approval to other Audit services, which are those services that only the Independent Auditors reasonably can provide. Other Audit services may include statutory audits and services associated with SEC registration statements (on Forms N-1A, N-2, N-3, N-4, etc.), periodic reports and other documents filed with the SEC or other documents issued in connection with securities offerings. The Audit Committee has pre-approved the Audit services in Appendix B.1. All other Audit services not listed in Appendix B.1 must be specifically pre-approved by the Audit Committee (or by any member of the Audit Committee to which pre-approval has been delegated). 4. AUDIT-RELATED SERVICES Audit-related services are assurance and related services that are reasonably related to the performance of the audit or review of the Fund's financial statements and, to the extent they are Covered Services, the Covered Entities or that are traditionally performed by the Independent Auditors. Because the Audit Committee believes that the provision of Audit-related services does not impair the independence of the auditor and is consistent with the SEC's rules on auditor independence, the Audit Committee may grant general pre-approval to Audit-related services. Audit-related services include, among others, accounting consultations related to accounting, financial reporting or disclosure matters 4 not classified as "Audit services"; assistance with understanding and implementing new accounting and financial reporting guidance from rulemaking authorities; agreed-upon or expanded audit procedures related to accounting and/or billing records required to respond to or comply with financial, accounting or regulatory reporting matters; and assistance with internal control reporting requirements under Forms N-SAR and/or N-CSR. The Audit Committee has pre-approved the Audit-related services in Appendix B.2. All other Audit-related services not listed in Appendix B.2 must be specifically pre-approved by the Audit Committee (or by any member of the Audit Committee to which pre-approval has been delegated). 5. TAX SERVICES The Audit Committee believes that the Independent Auditors can provide Tax services to the Fund and, to the extent they are Covered Services, the Covered Entities, such as tax compliance, tax planning and tax advice without impairing the auditor's independence, and the SEC has stated that the Independent Auditors may provide such services. Pursuant to the preceding paragraph, the Audit Committee has pre-approved the Tax Services in Appendix B.3. All Tax services in Appendix B.3 must be specifically pre-approved by the Audit Committee (or by any member of the Audit Committee to which pre-approval has been delegated). 6. ALL OTHER SERVICES The Audit Committee believes, based on the SEC's rules prohibiting the Independent Auditors from providing specific non-audit services, that other types of non-audit services are permitted. Accordingly, the Audit Committee believes it may grant general pre-approval to those permissible non-audit services classified as All Other services that it believes are routine and recurring services, would not impair the independence of the auditor and are consistent with the SEC's rules on auditor independence. The Audit Committee has pre-approved the All Other services in Appendix B.4. Permissible All Other services not listed in Appendix B.4 must be specifically pre-approved by the Audit Committee (or by any member of the Audit Committee to which pre-approval has been delegated). 7. PRE-APPROVAL FEE LEVELS OR BUDGETED AMOUNTS Pre-approval fee levels or budgeted amounts for all services to be provided by the Independent Auditors will be established annually by the Audit Committee. Any proposed services exceeding these levels or amounts will require specific pre-approval by the Audit Committee. The Audit Committee is mindful of the overall relationship of fees for audit and non-audit services in determining whether to pre-approve any such services. 8. PROCEDURES All requests or applications for services to be provided by the Independent Auditors that do not require specific approval by the Audit Committee will be submitted to the Fund's Chief Financial Officer and must include a detailed description of the services to be 5 rendered. The Fund's Chief Financial Officer will determine whether such services are included within the list of services that have received the general pre-approval of the Audit Committee. The Audit Committee will be informed on a timely basis of any such services rendered by the Independent Auditors. Requests or applications to provide services that require specific approval by the Audit Committee will be submitted to the Audit Committee by both the Independent Auditors and the Fund's Chief Financial Officer, and must include a joint statement as to whether, in their view, the request or application is consistent with the SEC's rules on auditor independence. The Audit Committee has designated the Fund's Chief Financial Officer to monitor the performance of all services provided by the Independent Auditors and to determine whether such services are in compliance with this Policy. The Fund's Chief Financial Officer will report to the Audit Committee on a periodic basis on the results of its monitoring. Both the Fund's Chief Financial Officer and management will immediately report to the chairman of the Audit Committee any breach of this Policy that comes to the attention of the Fund's Chief Financial Officer or any member of management. 9. ADDITIONAL REQUIREMENTS The Audit Committee has determined to take additional measures on an annual basis to meet its responsibility to oversee the work of the Independent Auditors and to assure the auditor's independence from the Fund, such as reviewing a formal written statement from the Independent Auditors delineating all relationships between the Independent Auditors and the Fund, consistent with Independence Standards Board No. 1, and discussing with the Independent Auditors its methods and procedures for ensuring independence. 10. COVERED ENTITIES Covered Entities include the Fund's investment adviser(s) and any entity controlling, controlled by or under common control with the Fund's investment adviser(s) that provides ongoing services to the Fund(s). Beginning with non-audit service contracts entered into on or after May 6, 2003, the Fund's audit committee must pre-approve non-audit services provided not only to the Fund but also to the Covered Entities if the engagements relate directly to the operations and financial reporting of the Fund. This list of Covered Entities would include: Morgan Stanley Retail Funds Morgan Stanley Investment Advisors Inc. Morgan Stanley & Co. Incorporated Morgan Stanley DW Inc.

(f) Not applicable. (g) See table above.
