APPLIES TO


 * Microsoft Exchange Server 5.5 Service Pack 3

This article was previously published under Q271711





SYMPTOMS
When a mailbox that contains an autoforward rule attempts to process the rule, if a message contains an attachment and the server uses a program that is based on the antivirus application programming interface (API), the information store may disable the autoforward rule.

The client receives a &quot;Rule In Error&quot; error message that lists the name of the rule with the reason &quot;Unknown Error.&quot;



CAUSE
This issue can occur because the antivirus API scans any attachments.

If the information store does not detect this condition when the attachment is being scanned, the information store disables the rule.



RESOLUTION
To resolve this problem, obtain the latest service pack for Exchange Server 5.5. For additional information, click the following article number to view the article in the Microsoft Knowledge Base:

NOTE: When you start this version of the information store, the information store databases are automatically upgraded to a new format. After the databases have been upgraded, you can restore an earlier version of the Store.exe file on the server, but only if it is version 5.5.2652.68 or later. If you restore a Store.exe file earlier than version 5.5.2652.68 after the database has been upgraded, you are no longer able to start the information store.

MORE INFORMATION
