I have move a client away from an old self hosted POP3 mail solution to office 365 and I need to try to configure his outlook so that emails come through in the way he is used to.
He has 4 different email accounts across 3 domains:
With pop emails from all 4 accounts would be stored in a single inbox in a combined PST file. He could reply to an email recieved by any account as that account with the relevant signature automatically upon clicking reply.
With the new office 365 setup I can only see two possible options. Having individual inboxes in the sidebar for each account, which he does not want. Or the way that I currently have things set up, use rules within Exchange admin to automatically redirect all mail to a single inbox (email@example.com), he can then manually change the from address and signature each time he replies. Which is unecessary extra steps.
Is there anyway to have a single inbox for multiple imap accounts within Outlook 2013, where the reply account can be automatically detected?
