Moving users or mail files between servers that use shared mail
You may need to move mail files when you need more space on a server or when users change jobs. When moving a mail file from a server that uses shared mail, the Administration Process (AdminP) automatically unlinks the existing mail file from any shared mail databases to which it may be linked, creates the new mail file, replicates mail to the new mail file, and deletes the old mail file. When using the Move Users tool to move a mail file, you can specify whether to use shared mail on the new server.
