I wanted to give access to all mailboxes so I set the add-adpermission for a user account and I found out it only gives me access to the mailbox if I add the mailbox through the Outlook Client. If I access it through OWA it will give me a access denied unless I explicitly give access to each individual mailbox.I am thinking it has something to do with the way I access the mailboxes through OWA/user@domain.pvt. I have set a recepient policy that accepts mail from domain.public for all mailboxes and it is primary? Obviously the permissions on the AD identity worked because it works when accessing all users mailboxes through the client. Any ideas?
