Sending email as alias in office365?
Assuming the following:
You have a user with mailbox and e-mail address userA@contoso.com and you want him to receive and send mail from an address userA@aliasdomain.com.
Do the following:
1. Create a distribution group with e-mail address, the alias f.e. userA@aliasdomain.com
2. Add the user's primary account as a member to this distribution group (Members => userA@contoso.com) to make sure e-mail gets delivered to his mailbox.
3. Set External Senders as required
4. Make sure membership approval is set to not allow other members
5. Set Send As permissions for userA@contoso.com
Now this user can receive e-mail on his new userA@aliasdomain.com e-mail address + send from this e-mail. The only thing he needs to do is in Outlook or OWA select the From and change it to the alias address.
Cheers,

Joey Bergen thanks, these steps helped me to configure it for my case (had to use classic GUI of exchange admin to find the settings). To other office365 email addresses, this works, but to some other addresses it doesn't; "This message could not be sent. You do not have the permission to send the message on behalf of the specified user. " Thought it had to do with some delay in processing of the changes, but next day still have the issue. Or do I also need to have changes on the DNS level, for example to inform target mail servers to that my domain A is allowed to send messages of my domain B...? any ideas?
- a separate issue is adding all the appropriate dkim, dmarc spf to your dns for each domain
- I ran into a similar issue several years ago when i converted to using DistList as my conduit to setup other distinct email addresses to send and receive email .. i have multiple domains and want to be able to select specific email address to send as and for that to go as that email rather than my primary account email/domain
My recollection after adding this dist list for each separate email address .. Next outlook (windows desktop), make sure the from field exposed, click new email, click From .. at bottom of dropdown .. "other email address" ... my first instinct was to type in the email i setup on the DistList but when i sent this triggered error similar to what you report above, so solution after calls with Support was to just select directly from Global Address list .. once this is done it looks same as if you type it manually but the email goes without error. Once you get each email address setup in this fashion the UI in outlook remembers and you can select from the remembered emails in the dropdown. Again if you manually type in the email address it will also be remembered and fail to send each time. Just click and delete to remove then select directly from global address List per above.
Hope that helps.userhtx as it now works in the Outlook client on windows and also in OWA, in another case we're still not able to access this functionality (send as distribution list user) on the Mac with Outlook locally installed - do you know, is there a way to achieve that?
- sorry i do not mess with macs
userhtx Indeed, I have never had an issue using "Send As" with the full desktop Outlook application. In my experience, the issue described where using "Send As" shows the alternate From to other internal emails but will show your primary email and disregard the "Send As" when emails are sent externally only happens with OWA. Apparently, Microsoft has a fix for this on their roadmap. In the meantime, people who are unable/unwilling to use the desktop application can workaround the issue by opening the shared mailbox in a separate browser tab using the URL I linked above.
- Let me add another element of the retirement of the connected accounts is auto-populate the reply that populates the from field on an reply. Connected accounts had this feature. As i said MS retired the connected accounts a couple years ago. This forced me to shift my setup to manage my distinct email identities (different domains and funneling into one main account) via use of the DistList permissioned to send as ... but the Dist list approach did support auto-populate from on reply. For example, external sender sends to one of my identity email addresses i have setup in parallel using DistList .. such as name@domain2.com where name@domain1.com is my main account .. so from my inbox i would like to just open the email and click reply and the name@domain2.com would auto populate the from field .. instead with the DistList approach i have to manually set from by picking from dropdown every time .. with the former connected account this feature auto-populated the from field and i found that far more efficient and less subject to accidentally missing that selection which then sends out as the main name@domain1.com .. ie wrong identity.
Do you know if that config / feature has been added back?
