Sending email as alias in office365?
This is manifestly untrue. My previous post details steps for this to be achieved in a trivial way using Outlook 2016 and Office 365, one of the most common deployment combos.
Hi James O'Sullivan. Edited because I've just looked at the images you posted.
Have you tried sending from an alias with a different domain (but one that is registered in O365)? I note that your aliases are all in the same domain (unless differences are redacted)?
I've tried sending from aliases both in the same and different domains as my primary smtp address and neither works.
If it is definitely working for you, there must be some configuration (permissions, perhaps) or other nuance of how domains are set up (or maybe hosted or not hosted in O365) that is different.
Thanks
Nick
