I have created a number of distribution lists under the groups tab just to the right of mailboxes in the recipients section of the exchange admin centre in microsoft exchange 2013.
i have set permission on these mailboxes for send as to be permitted but when trying to send mail from outlook 2013, outlook web app or from ios i am unable to get the distribution lists email address to appear in the from list.
could someone please explain how i can resolve this for each of these 3 platforms?
