Sending email as alias in office365?
Paul Murana i tried your solution ie created a pop 3 for an alias that i created via office365 (not powershell as that's too advanced for me).. the email came from my main account...
ab1234260 but did you try sending it outside of your own tenant? If you send it to an internal recipient it will always come from your main account.
Paul Murana one problem is that the email comes in to the alias but when i hit reply it sends from my main account again... would a share mailbox be better than this approach in your opinion ?
ab1234260Something I just thought of is created a rule in exchange to tag the message saying it was sent to a certain account which would work for my scenario however maybe not for yours. The only issue I see is in my testing I am unsure of what to put for specify header name. The secondary alias DOES show up in the header so that is promising.
FYI here for reference if I put To as the specified header name it works however when testing a reply email it does not match the rule but when creating a new email message it does. Here is a list of headers:

I tried In-Reply-To, Reply-To, and References with no luck. Regardless that is getting off topic but wanted to mention it in case someone else was wondering what to enter in the specified header field.
Back on topic I like they are looking to add the feature in OWA by the end of this year

All my users use the Outlook program but it is a start.
ab1234260I tested what you have said and that is interesting because it used to work when replying. I did not see Paul Murana's instructions but I bet they are similar to what I am using. From an outside email address if I email mailto:test@secondalias.com it comes into the exchange as the primary account so when you click reply it replies from the main account. Very annoying because I have been using this method for almost 10 years now and in the past when an outside entity emailed an alias it came in as that alias. Sounds like in your scenario a shared inbox would be best. I can't do that in my scenario unfortunately.
Paul Murana **bleep** i didn't try that! Will do but now i have to turn off the distribution group i tried instead!
