I successfull migrates 73 out of 74 mailboxes during my sbs2003 to sbsb2008 migration.but of course the one mailbox we need, the directors, didnt come over. Probably becuase it is over 4.5 GB. I have turned off the mailbox limits on the SB2008 server. However I accidenlty maked the mailbox migration on the SBS Migration wizard as complete. If I go into Exchang Management her mailbox is still listed as a legacy mailbox. If I choose to move it from the old server to the new server it tells me it cant because it already exists. How do I restart the migration for just the remaining mailbox?
