During routine background processing, the content of each mailbox size is checked against its limit. If a message contains a pointer to an attachment that is not found in the attachment table, this event is logged. The event may be logged if you use the ISScan utility to remove certain attachments because the messages have pointers to the attachments.

Note We do not recommend using the ISScan utility. For information about viruses and antivirus software, contact your antivirus software vendor or visit the following Web sites:

These events are harmless and disappear when no more messages that contain the removed attachment exist.

You can use the following command in the ISInteg utility to resolve this behavior: Exchange Server 5.5: Exchange 2000 Server: where servername is the netbios name of the Exchange 2000 server.

The ISInteg utility is a standard utility that is installed with Microsoft Exchange Server. The ISInteg utility is located in the Exchsrvr\Bin folder.
