Sending email as alias in office365?
I used to have my domain email hosted in office 365. The reason i switched was because of a lack of a feature i really needed. You had the ability to create multiple aliases in office 365 so you coul...
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?
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.
