Hello,
I would like to share my experience on Enable-Mailbox AND Set-Mailbox cmdlets when managing a Linked Mailbox.
In fact, when I try to Enable or Update a linked mailbox with a LinkedMasterAccount already set for another linkedmailbox, it is not always detected. It is detected if I use the name of the LinkedMasterAccount, but not when I use its SID.
Environnement: Remote PSSession on Exchange 2010 server (Version 14.2 (Build 247.5))
The only solution I actually have that is to convert the SID to Name before enabling OR setting the Linked mailbox. My script is processing 60000 accounts in every cycle, so it takes some long to convert all LinkedMasterAccounts SID to Name (10mins)...
