This problem may occur if file-level antivirus software is installed on the Exchange 2000 computer, and the antivirus software is configured to scan the Exchange directory structure. We strongly recommend that antivirus software be configured so that the EXCHSRVR directory and drive M (if exposed) are excluded from scans.
To resolve this problem, configure your antivirus software to exclude the Exchange directory structure from file-level scanning. For additional information about anti-virus software and Exchange 2000, click the following article numbers to view the articles in the Microsoft Knowledge Base:
