I just had to Export few mailboxes to PST.
Just struck up with an Error.. Thought it is corruption…But the fix was beyond my thinking.
Exchange 2010 SP2

Go the Properties of the mailbox
Make Sure MAPI is Enabled
This wasn’t the cased in my environment. Luckily, restarting DAG nodes helped.
I use: Win 2008 R2 w/ Exchange 2010 SP3 RU2 (DAG)
Happy with it . Thanks for sharing your solution Seba
Thanks for this post, its realy worked.
Welcome 🙂 Hiren
Thanks for sharing. That was the solution on my case.
You are most welcome
Thank you for slution
Thanks, you just saved my day! 😉
You are most welcome 🙂 Han
Thank you for sharing your solution to this!!! I was scratching my head on this one and worried about my mail store since I had never seen a MailboxExportRequest fail before. I had this exact issue…I had disabled all protocols on a user’s mailbox, something I’d never bothered with before, and sure enough re-enabling MAPI fixed it.
Thanks bro that really work for it.
You da Man-oharan!
It worked! I believe the user should not be disabled in AD as well.
Thank you for your comments !
it doesn’t matter user is disabled in AD. worked for me with same.
Your Welcome !!
New-MailboxExportRequest : Couldn’t connect to the source mailbox error only for few mailboxes
I exported 700+ mailboxes from same exchange server and stuck with few mailboxes giving me same error.
group of mailboxes which are giving me same error have nothing in common, they don’t belong to same OU.
checked mailbox features properties as well. MAPI is enabled.
mailboxes which are giving me error exist in exchange, no spelling mistake
I am not understanding when same command in same server worked for 100’s of mailboxes why it doesn’t work for few mailboxes?
This worked for me…thanks for the solution.
Happy for you
Thanks the issue is resolved….
thank you and keep posting good stuff like this
Also check the MAPIBlockOutlookNonCachedMode setting. If this is set to True, the export will fail with the same “Couldn’t connect to the source mailbox” error.
In Exchange Shell:
Set-CASMailbox -MAPIBlockOutlookNonCachedMode $false
I really do believe each of the ideas you may have offered on your own post.
These are very convincing and can definitely work.
Still, the posts are too short for starters. Might just you please prolong them a
little bit from subsequent time? Many thanks for the post.
I love you, thanks, ME ESTABA VOLVIENDO LOCO
your welcome !
i checked, and for my users MAPI is enabled on checking Exchange console
also tried CASMailbox -MAPIBlockOutlookNonCachedMode $false. But my export is still failing
