A common problem - we have many users and as the administrator are often asked to set out of office greetings for users who are not at work but did not set their own greeting. We are using Exchange 2013. I know that I can go to the EAC - signed on as the domain/administrator - and then at the top right where it shows - administrator - I can use the drop-down to select - Another User. Then a window opens up showing at the top - domain/administrator is working on behalf of User Name. In this window it shows: Shortcuts to Other Things You Can Do. One of the options is - Set Up An Automatic Reply Message - easy enough.....one would think.
The problem is that some user mailboxes show this option and others do not. I don't understand why some show it and some do not. What setting determines if this option is available for a given mailbox?
