New-MailboxExportRequest Couldn't connect to the source mailbox

After reconnecting a disabled mailbox and attempting to run an export request you receive the following error:

[PS] C:\Windows\system32>New-MailboxExportRequest user1 -FilePath "\\dcexmailp01\PST Dumps\srosenwinkel1.pst"


Couldn't connect to the source mailbox.

+ CategoryInfo : NotSpecified: (0:Int32) [New-MailboxExportRequest], RemoteTransientException

NewMailboxExportRequest
 
You attempt to log into webmail and you receive:
 
Exception


Exception type: Microsoft.Exchange.Data.Storage.AccountDisabledException

Exception message: Cannot open mailbox /o=first organization/ou=exchange administrative group (fydibohf23spdlt)/cn=recipients/cn=user1.
 
In this instance I reconnected a disconnected mailbox to a new user. Thinking it was the DS cache I waited for some time. There is a KB article http://support.microsoft.com/kb/2682047
 
"You cannot access a mailbox for several hours after you disconnect and then reconnect the mailbox in an Exchange Server 2010 SP2 environment" which says to install SP2 RU3 which is already installed.


After some time had elapsed, I attempted to disable the mailbox and reconnect and still same error.
 
When you run get-mailboxstatistics user1 |fl you see
 
DisconnectDate : 2/3/2013


DisconnectReason : Disabled
 
To resolve this error, once you have reconnected the mailbox you have to run
 
get-mailboxdatabase |clean-mailboxdatabase again.
