The information in this article applies to:

- Microsoft Exchange Server, versions 5.0, 5.5 
-------------------------------------------------------------------------------

SYMPTOMS
========

When trying to access an NNTP service provided on an Exchange Server computer,
you may receive error 502: No permissions

CAUSE
=====

The error has one of four possible causes:

- Anonymous access is not enabled for the NNTP protocol.

- The incorrect password has been entered.

- The account used for validation has been incorrectly entered.

- The account used for validation has a duplicate alias between multiple
  mailboxes for mailbox and custom recipients.

WORKAROUND
==========

To work around this problem:

- If anonymous access is not enabled for the NNTP protocol, grant anonymous
  access.

- If an incorrect password has been entered, verify and use the correct
  password.

- If the account used for validation has been incorrectly entered, verify and
  use the correct account.

- If the account used for validation has a duplicate alias between multiple
  mailboxes for mailbox and custom recipients, change the alias used on the
  custom recipient so that it does not match the alias on the mailbox.

MORE INFORMATION
================

The No permissions error is caused by a problem with validation. During the
validation process, the logon name is compared to the alias of a mailbox or
custom recipient.
