"MapiExceptionMailboxDisabled: Unable to open message store" error


When trying to re-connect a disconnected mailbox from PowerShell with the "Connect-Mailbox" command, you get the following error message:
"MapiExceptionMailboxDisabled: Unable to open message store"

When trying to re-connect it from the GUI, you don't even see the user you want to link the mailbox to.


Make sure the Active Directory user account is not disabled.

You can use the following command to enable the user:
net user WHATEVER /active:yes /domain

Affected software:

Microsoft Exchange 2007
Microsoft Exchange 2007 SP1
Microsoft Exchange 2007 SP2
Microsoft Exchange 2010
Microsoft Exchange 2010 SP1
