Hi all,
I cant believe I’m asking this question as it seems ridiculous but in exchange 2013 have Microsoft removed the ability to open up a mailbox logged in as UserA and open up UserB's mailbox.
Permissions are all fine, UserA can open up UserB from within their Outlook profile and can open it via OWA.
When it comes to opening it up via a second outlook profile it just will not work. We still have most of the Org on 2010 and those mailboxes open fine, DNS is pointing to 2013 so the proxying back is fine. So its just affecting those mailboxes on 2013, doesnt matter if its a Regular user, linked, equipment or room mailbox, None will open unless you are logged in as the primary user account for that mailbox.
I’ve now read a couple (i know that’s not definitive) of articles where it seems people are reporting this problem and no one has come up with a fix\working solution.
Can anyone with Exchange 2013 confirm this does work?
We are still in an RPC over HTTP model as, hoping to enable MAPI over HTTP in the
future.
Thanks
