Archiving is not a difficult concept to get over to users, as the archive mailbox simply appears as another mailbox in their profile. However, there are limitations in its use, so you need to consider the following planning factors when implementing this service:
Client compatibility – the archive mailbox isonly accessible through Outlook and OWA.
Availability – the archive is for online usage only and is not available offline.
Compliance – how will archiving integrate with journaling and eDiscovery?
Training – although not difficult to learn, users need to know how to use the archive mailbox, along with retention policies.
Policies – identify and apply archive policies so that users can select how items are moved to their
archive mailbox.
