Recently we had to reinstall the MS Exchange 2010 server as the one in use from time to time just randomly froze. This installation was anything else than trivial…
1. If you think it is a good idea to reuse the existing database to save time (it saved me -2 days time)
2. I had a problem reattaching the database to the new server. Found that there is a limitation for the log files… If they are too big it just fails. Had to do use Eseutil to clean the database.
3. I had to reattach every user mailbox using “Connect-Mailbox” command ( you can get a list with “Get-MailboxStatistics -Database MBD01 | Where { $_.DisconnectReason -eq “Disabled” } | Format-List LegacyDN, DisplayName, MailboxGUID, DisconnectReason” )
BTW when you install the exchange server, the name of the EXCHANGE ORGANISATION HAS TO BE THE SAME.
