Exchange 2013 Mailbox permissions.
I have given user1 as mailbox owner for user2 mailbox.
I opened Outlook on user1 PC and added user2 mailbox to user1 outlook.
However when user1 tries to expand user2 mailbox, it gives error "cannot expand the folder"
How can I fix that ?
there is also user3 mailbox that I added to user1 mailbox with no issue, and there is also no issue to expand user3 mailbox from user1 Outlook. However I need user1 to send email as user3 instead of "on behalf of user3", how can I accomplish that.
