My company recently switched to Office365 - so now email is all 'in the cloud' - since the move, the autodiscover service no longer works.
We use an appID for automation emails - I've tried putting in
outlook.office365.com as the host, along with the appID and password (and I've also tried my ID & PW) - all I get is '(401)) Unauthorized (System)'
Any ideas how to get Exchange to work. SMTP still works (for sending), but I'd much rather use Exchange services.
