Migrating Mail Message Files
Mail message files (MMFs) store mail, attachments, and PABs for
Windows and OS/2 clients using Microsoft Mail for PC Networks
version 3.x . The MMFs can be stored in the postoffice share
in the MMF directory, or they can be moved to another location on
the client; for example, the user's local drive.
If the MMFs are stored locally, rather than migrating them using
Migration Wizard, users can import their MMFs directly
using Outlook .
The following table describes the benefits and drawbacks of
moving MMF files to different locations.
