Hi All,
I found a odd issue these servers are patched to the same level. Exchange 2010 SP2 RU6.
I have tested this in our lab with the same result. Seems to be a fault with the CMDlet
SourceVersion : Version 14.2 (Build 342.0)
SourceDatabase : Mailboxes Q-T
TargetVersion : Version 14.2 (Build 247.0)
TargetDatabase : User Mailboxes DB4
Thanks
Josh
