Report of Independent Registered Public Accounting Firm

To the Trustees and Shareholders of Putnam Municipal
Opportunities Trust

In planning and performing our audit of the financial
statements of Putnam Municipal Opportunities Trust (the
Fund) as of and for the year ended April 30, 2020, in
accordance with the standards of the Public Company
Accounting Oversight Board (United States) (PCAOB), we
considered the Funds internal control over financial
reporting, including controls over safeguarding
securities, as a basis for designing our auditing
procedures for the purpose of expressing our opinion on
the financial statements and to comply with the
requirements of Form NCEN, but not for the purpose of
expressing an opinion on the effectiveness of the Funds
internal control over financial reporting.  Accordingly,
we do not express an opinion on the effectiveness of the
Funds internal control over financial reporting.

The management of the Fund is responsible for
establishing and maintaining effective internal control
over financial reporting.  In fulfilling this
responsibility, estimates and judgments by management
are required to assess the expected benefits and related
costs of controls.  A companys internal control over
financial reporting is a process designed to provide
reasonable assurance regarding the reliability of
financial reporting and the preparation of financial
statements for external purposes in accordance with
generally accepted accounting principles.  A companys
internal control over financial reporting includes those
policies and procedures that (1) pertain to the
maintenance of records that, in reasonable detail,
accurately and fairly reflect the transactions and
dispositions of the assets of the company (2) provide
reasonable assurance that transactions are recorded as
necessary to permit preparation of financial statements
in accordance with generally accepted accounting
principles, and that receipts and expenditures of the
company are being made only in accordance with
authorizations of management and directors of the
company and (3) provide reasonable assurance regarding
prevention or timely detection of unauthorized
acquisition, use or disposition of a companys assets
that could have a material effect on the financial
statements.

Because of its inherent limitations, internal control
over financial reporting may not prevent or detect
misstatements.  Also, projections of any evaluation of
effectiveness to future periods are subject to the risk
that controls may become inadequate because of changes
in conditions, or that the degree of compliance with the
policies or procedures may deteriorate.

A deficiency in internal control over financial
reporting exists when the design or operation of a
control does not allow management or employees, in the
normal course of performing their assigned functions, to
prevent or detect misstatements on a timely basis.  A
material weakness is a deficiency, or a combination of
deficiencies, in internal control over financial
reporting, such that there is a reasonable possibility
that a material misstatement of the companys annual or
interim financial statements will not be prevented or
detected on a timely basis.

Our consideration of the Funds internal control over
financial reporting was for the limited purpose
described in the first paragraph and would not
necessarily disclose all deficiencies in internal
control over financial reporting that might be material
weaknesses under standards established by the PCAOB.
However, we noted no deficiencies in the Funds internal
control over financial reporting and its operation,
including controls over safeguarding securities, that we
consider to be material weaknesses as defined above as
of April 30, 2020.

This report is intended solely for the information and
use of the Trustees of Putnam Municipal Opportunities
Trust and the Securities and Exchange Commission and is
not intended to be and should not be used by anyone
other than these specified parties.
