Solved

Mailbox Migration failed, mailboxes shown as Disconnected. But Mailboxes are Still LIVE and in use.

We have two exchange 2010 servers in the site (EX01 and EX02).  EX01 is the primary, and EX02 is the secondary.

I logged onto EX01 and started a mailbox move without the MRS parameter and the moved started using EX02 as the MRS server (I found out later).

Later that night EX02 went offline.  One of the mailboxes showed as failed but the others completed with errors.  But all the mailboxes show up the disconnected section under the Recipient Configuration.

Now the Mailbox Assistance Event says that mailbox database is not completely healthy during the work cycle.



3 Questions:

1. Do I leave the disconnected mailboxes until they expire or do I remove them?

2. Do I repair the mailbox database using: New-MailboxRepairRequest -Database MBX-DB01 -CorruptionType ProvisionedFolder,SearchFolder,AggregateCounts,Folderview?

3. Anything else I need to do?

If you get some downtime, dismount and mount the databases of the source and destination...which should give you correct picture about the move-mailbox

I think what happened in this situation is that those mailboxes were actually copies, so when the mailbox moves failed they did not impact the existing mailboxes.

The next day the users were still up and running so I lowered the "deleted mailbox" retention to 1 day and exchange removed those mailboxes itself.

It created a whole heap of white space though.

I think I am ok now.

It appears exchange fixed it self.
