I have a failed Exchange 2003 server with little hope of bringing back online. I have an Exchange 2010 that I have running but cannot move mailboxes naturally through the 2010EMC due to the 2003 being offline. Beyond deleting and recreating the user account in AD is there a way to either force the exchange attributes to move to the 2010?? The user has mult pop accounts that will download thousands of emails back into (standard pop 14 day retention setting) and being the owner of the company honestly don't want to listen to the crap. No availability to recover from Buffalo backup due to Buffalo becoming corrupted when 2003 failed (backup server also) but wouldn't work due to backup attributes (if was good) is pointed to 2003.
As an FYI, trying something really stupid on an account that the user would at least cut me some slack on, I copied the email to a local pst and then deleted the mailbox in 2010EMC (ok was stupid) hoping would just delete the mailbox and not the user account but was not the case. So when I recreated the account pulled in 1500+ emails due to the 14 day pop settings.
I googled the hell out of this and there is nothing that I can find that says will accomplish the necessary AD property changes with the old server DOA. I need to finish this this w/e so any help would be appreciated.
