I recently had a hard drive failiure on a server running Exchange. The raid config got corrupt so all the data was lost. Luckily we had a 35GB NTBackup of Exchange. I restored this to a new /disasterrecovery Exchange server with the same name. It did the 15GB EDB but when it got part way into the STM it failed. After creating a blank STM we got the store mounted and email was flowing for a bit. A few days later it stopped working. Noticed that the database size was never increased from 18GB to 75GB (could be why the STM failed to restore....).
After increasing the DB size and restarting the information store email is still stuck in the local delivery queue. I created 2 new test users and can send mail back and forth with them. I can send internal and external email inbound/outbound with them. Works fine. Old users are not send/recieving any email. It gets stuck in the Local Delivery Queue. I have tried to do force connection and Unfreeze but nothing works. I have about 150 emails, 8MB.
What could get these old emails to work? Any new email old users send also get stuck in the queue. The first few emails sent 2 days ago are being deleted with NDRs, so it appears a corrupt email is not the cause.
