Hi,
We have been migrating a server from 2003sbs to 2011sbs, The migration process was previously started and abandoned half way through and the decision was taken to format the 2011 server and re-run migration from scratch. The first migration took all of the users and converted the mailboxes from all users. This was backed up before the format of the 2011 server and the AD of the 2003 server was cleaned up.
So I now have a list of users copied from 2003 during the second migration and a 10GB mailbox database on the new server with all the email in it (that came from the first migration). I created a new mailbox of the same name, dismounted and swapped with the old database in the hope it would bring everything together again.
The only problem is the mailboxes do not seem tie in with the users. For example if i right click on a user in ESM i get an error:
--------------------------------------------------------------------------
"The user does not have an Exchange mailbox. It was runnng the command 'Get-CalendarProcessing -Identity 'domainname.local/mybusiness/users/sbsusers/user' -ReadFromDomainController".
--------------------------------------------------------------------------
I also get the error
--------------------------------------------------------------------------
Warning: The object domain.local/users/sbsusers/user has been corrupted, and its in an inconsistent state. the following validation errors happened:
Warning: Database is mandatory on UserMailBox.
--------------------------------------------------------------------------
So I was just wondering what the best way past this was ? I cannot remigrate the boxes from 2003 as they were removed by the migration. Is it best to delete and remake the users in AD or make a new mailbox database and import the old database in to it ?
There are backups of the new database before it was remounted and it was a clean dismount before backup.
Thanks in advance for any suggestions or help.
