This either never came up before for us or a long time ago.
User A is on vacation but getting mail on their phone
User B wants to send as that user to a customer
we don't know user a's password. I could change that in the SBS 2011 and user b logs in and sends as them in OWA or similar. But that would break his email on his phone and require talking to him on vacation. Don't want to do that and that is low tech way.
Some googling, I go into EMC, server, recipient, mailbox and added user B using action on the right side 'manage send as permission' to user A - or do I have that backwards?
User B closed & opened outlook. Clicked on from button, typed user A name and tried to send to her personal email as test. it failed - you don't have permission.
Repeated steps adding user A to user B's 'manage send as permission'. Repeat and still failed.
Tried "manage full access permission" on user A's account and still failed.
Does it take time to update in exchange?
Am I doing something wrong?
Then once they send as user A, how does user B see user A's mailbox for the reply?
