Microsoft Exchange mailboxes backed up via the Microsoft Exchange Agent hang in random locations within the backup set if Anti-virus and/or Spam Filtering Applications are not configured properly

Details:

This behavior is evidence of an application conflict with anti-virus applications loaded on the Exchange server.

When using spam-filtering products, ensure that filter rules are configured to run against the incoming Simple Mail Transfer Protocol (SMTP) traffic instead of the Exchange Store.

When using file system anti-virus products, ensure that the application is configured to include these Exchange locations at the file or folder level as these are safe to scan:

Exchsrvr\Address
Exchsrvr\Bin
Exchsrvr\Conndata
Exchsrvr\Exchweb
Exchsrvr\Res
Exchsrvr\Schema
Any additional directories which are not a part of a standard Exchange installation, and are not included in the list of directories (shown below) which are unsafe to scan

•
When using file system anti-virus products, ensure that the application is configured to exclude these Exchange locations at the file or folder level as these are unsafe to scan:

In both versions of Microsoft Exchange, the Tmp.edb file may be found in more than one location. Search for the file, and exclude it from any of the locations where it is found.
