Convert user mailbox to linked mailbox in Exchange 2010
A few weeks ago, someone enabled the user accounts for a bunch of our Exchange 2010 linked mailboxes. One of the workflows in our FIM system saw this as an indication that they should be user mailboxes rather linked mailboxes and thus converted them all from linked mailboxes to user mailboxes.
I did a bit of research and was somewhat heartbroken to find this TechNet article
This article implied that converting user mailboxes back to linked mailboxes was not possible using the EMC.
After a bit more research and an email from Jason Sherry, I fortunately found out this article is wrong. (I'm hoping Microsoft updates this.)
It is pretty simple to convert a user mailbox with E2K10 SP2 or E2K10 SP3 back to a linked mailbox.
Set-User <userID> -LinkedMasterAccount AccountDomain\UserID -LinkedDomainController AccountDomainControllerFQDN
Here is an example:
Set-User jim -LinkedMasterAccount Contoso\Jmcbee -LinkedDomainController dc01.contoso.local
