Migration step five - getting Exchange into shape
Optimize Exchange Server 2003 mailbox sizes
Migrating large mailboxes from Exchange Server can take a long time. To save time, reduce the size of the mailboxes before the migration. Send an email message to users with the following instructions about how to empty the Deleted Items folder and archive older mail:
Show me a small firm and I'll show you a bunch of overweight mailboxes.
SMB folks run some of the biggest email accounts known to Microsoft.
We run with fat, bloated mailboxes and quite often boast about the size of our OSTs.
In addition to telling people that Exchange is not a filing cabinet, do yourself a favor and do a trick that Amy Babinchak of www.thirdtier.net strongly recommends before a migration... running an eseutil.
Review this blog post -- http://msmvps.com/blogs/bradley/archive/2009/11/09/eseutil-before-the-move-mailbox.aspx or grab a copy of the SBS 2008 David Overton book and remind yourself of how to use eseutil if you haven't done it in a while.
Your migration will be made a ton easier if the mailboxes and not too big, nicely defragmented and ready to go.
