Running Outlook 2010 & 2013 with Exchange 2013 (on premise). The behaviour I'm trying to achieve is
- for a user to have access to a shared mailbox,
- have sent items go to the sent items folder of the shared mailbox, and
- have new/reply messages from the shared mailbox show personA on behalf of sharedX.
No 1 easy enough - full access granted. Shows up automatically or loaded as extra account in Outlook client.
No 2 not so easy/intuitive, but loading it as an extra account in Outlook seems to do the trick. Simply responding from an auto mapped mailbox puts the sent message in your personal sent items and not the shared mailbox sent items folder. If there is a smarter/more intuitive/sensible way of doing this at scale please let me know!
No 3 is where I'm getting stuck. If I remove full access and grant SendOnBehalf using EMS (http://technet.microsoft.com/en-US/library/jj150498(v=exchg.150)) I get #3 to function as required, but not with full access still granted which in turn breaks requirement #1 & #2.
Am I missing something obvious or is this a very real limitation/shortfall in the Exchange/Outlook ecosystem? The fact that the EAC does not even cater for Send On Behalf on a shared mailbox gives me little hope that this is/was a thought through scenario for the Exchange team.
As an aside - It would be very useful if MS had a definitive guide on how to configure these 'common' scenarios - perhaps the topic for a series of blogs by the Office/Exchange server teams?
