I have a new server on sbs 2008 with exchange 2007, and an older server with sbs2003 and exchange 2003. I am just looking for the fastest way to export mailbox data and import to the new server. The new server is already setup and working, only thing left is MX record changes. I DID do some cleanup where I standardized email addresses so its first initial lastname, they had the majority of users in that scenario but not all of them. For the one-offs that were firstname.lastname or whatever, I added that as an additional email address to the new standardized account, in case that matters (saying its not a direct 1:1 from username to username).
