Hi Paul,

Sorry for being late here.

You said to use the same CU version when doing a recovery. However ours was a 2016 CU 10 server(when dead), however all the other DAG servers are 2016 CU14 now. And we are in a process of upgrading all the servers to CU15 already. Hence wants to recover this one with 2016 CU15 as a fresh server and then add it to DAG.

Do you suggest anything different or if there are any recommendations with it.

Would really appreciate your help.

Fix an error 500 after a reinstall
This is due to the an unmounted database.

### Get Mailbox name
Get-MailboxDatabase -IncludePreExchange2013

### Get the status of the
Get-MailboxDatabase -Identity “Mailbox Database” -Status | Format-List

### Mount the database:
Mount-Database -Identity “Mailbox Database”

Don’t know If I should create a new Thread but cant see where to do that.

This all stems back to a corrupt database which happened 3 months ago and would not mount and failed to allow all the usual Get-Mailbox etc etc commands. We left it there for a while but Backups also kept failing. We had managed to transfer all the users mailboxes to new databases and the Exchange server has continues to run fine.

I tried to remove the Corrupt database but had no luck so in a fit of pique I deleted it. Big Mistake

The exchange server continued to run but certain features didn’t work such as creating a new outlook profile/account hence we couldn’t move users to a new PC.

So far we have restored from backups and the then incremental that only had the database’s in.

VERITAS BUExec moaned and didn’t complete the restore until but only after it had been running for 8 hours!! (why it couldn’t tell us a bit earlier I don’t know!!)

Anyway after researching the subject a lot I am firmly of the opinion that the/a system mailbox was on the corrupt database but I this Database was not mounted I assumed it didn’t matter.

incidentally a CU14 update also failed.

So my question is do I just need to locate the missing system mailboxes in ADSIedit and delete them or will /prepareAD recreate them.

OR is there such a thing as a repair install?

I will be applying Cumulative Update 14 for Exchange Server 2016 n a stand alone server this weekend in preparation for an office 35 migration project. I have done all he ground work and I believe I am well prepared for it. It’s a stand alone server. I wish it was in a DAG configuration, would have made it more easier to stagger the CU update between DAG members. I want to say that your articles have been very helpful over the years. Thank you and keep on sharing your knowledge.
