SUMMARY
Do not try to back up or to use an antivirus scanner against drive M of an Exchange 2000 Server computer. If you do this, problems may occur with calendaring, such as disappearing appointment items, access to attachments and messages, damage to the Exchange 2000 database, mail flow issues, and receiving false reports of a virus. Additionally, you may notice an unusually large number of transaction log files being created in the Program Files\Exchsrvr\Mdbdata folder or in the transaction log file location. These files may be created at approximately the same time on a nightly or weekly basis.

MORE INFORMATION
Only back up Exchange 2000 Server with an Exchange 2000-aware agent. To properly protect your Exchange 2000 Server computer from viruses, you must use antivirus software that is Exchange 2000-aware. If you also need file-level protection on your server, you must make sure that you exclude drive M and also all of the Exchsrvr folders. Please note that you may have Exchsrvr folders on multiple drives. For more information about how to exclude drives with your Exchange 2000-aware antivirus agent, refer to that product's documentation.

Additionally, do not scan the files in the following folder:

%SystemRoot%\System32\Inetsrv
