When trying to export a mailbox to PST , we face the error
Couldn’t connect to the source mailbox.

Exchange 2010 relies of MAPI when performing any mailbox export. I had to enable MAPI.
So all what you have to do is to enable the MAPI from the mailbox properties as below
Now run the command one more time after enabling the MAPI
Ran up on this pretty early on when setting up a PST archival process for terminated accounts… as part of their term process was to disable MAPI. Just a note to others… You may need to wait up to 2hrs (stock setting) before Exchange re-caches in the AD info that includes this change. I can say after working with the new MRS related commands I’m not fond of the change, but of well.
