Ladies and Gentlemen:

Pursuant to Rule 477 of the Securities Act of 1933, as amended (the “1933 Act”), Putnam Municipal Opportunities Trust (the “Fund”) hereby requests that the Commission consent to the withdrawal of Pre-Effective Amendment No. 1 to the Registration Statement of the Fund on Form N-14 that was filed with the Commission on August 7, 2007, along with any exhibits; Pre-Effective Amendment No. 1 to the Registration Statement on Form N-14 that was filed with the Commission on August 24, 2007, along with any exhibits; and Pre-Effective Amendment No. 2 to the Registration Statement of the Fund on Form N-14 that was filed with the Commission on September 11, 2007, along with any exhibits (collectively, the "Amendments").

The Fund requests that such consent be granted on the grounds that the Amendments were filed by the Fund with the Commission under an erroneous registration number. The Fund confirms that no securities have been sold under the Amendments.

Should you have any questions regarding the Fund’s application for withdrawal, please do not hesitate to call Melissa S. Gainor of Ropes & Gray LLP at (202) 508-4662 or George B. Raine of Ropes & Gray LLP at (617) 951-7556. Thank you for your assistance.
