I Cannot Determine the Purpose of the M Drive

Valid in all Exchange Server systems.

Symptom:

I cannot determine the purpose of the M drive and do not know if it needs to be backed up.

Solution:

The M drive (ExIFS) is a virtual drive that exposes Exchange Server 2000 mailboxes and public folders. It is simply a view of Exchange Server 2000 and not a physical drive, so you do not need to back it up, which is why it is skipped when you perform a backup job using the Client Agent for Windows.
