#SEND EMAIL AS ALIAS O365 UPDATE#

For Outlook, itвЂ™s much the same except that you need to go to Options first. Make sure that the From field is exposed in the message compose form. That client-side tweak isnвЂ™t available yet, but the same approach used to send messages on behalf of or as a shared or group mailbox works using either OWA or Outlook desktop. The roadmap item says that OWA will allow users to select which address to use from a drop-down list (this is what we should see when MC252942В arrives in early May). After a few hours, you should be ready to try sending messages using proxy addresses. Clients must also refresh their settings. Set - OrganizationConfig - SendFromAliasEnabled $ TrueДЄfter updating the organization configuration, it takes some time before all the mailbox servers used by a tenant learn about the update. As you can see, a proxy address can use any of the domains registered for the tenant (the accepted domains). One is the primary address, used by default whenever the user sends email. More prosaically, people might have addresses accumulated over the years generated using different address schemes.ДЇigure 1 shows the email addresses available to an account as seen through user settings in the Microsoft 365 admin center. This happens to allow users to continue to receive email using their old and new addresses, and while people usually send new messages using the new company email address, it might be that they need to use the old address until the merger is fully closed. For instance, if your company is involved in a merger, your mailbox might have addresses for both the old and new company. Mergers and Acquisitions and Other UsesД«eing able to send email using a selected proxy address is useful in several scenarios.

#SEND EMAIL AS ALIAS O365 UPDATE#

Update April 27: Message center notification MC252942В says that OWA will get support for the send from proxy address feature in early May. The early release of a useful new feature is always appreciated, even if I suspect that the feature is only released on the Exchange Online side at present with some client-side work still to come to make the task easier to perform. This is Microsoft 365 roadmap item 59437, which the roadmap says is due for release in June 2021. This week, Microsoft rolled out an update to allow clients to send messages using any SMTP proxy address assigned to a userвЂ™s mailbox. Exchange Online can accept and deliver email addressed to any proxy address for a mailbox, but up to now users have been unable to use their non-primary SMTP addresses when sending messages. One of the addresses, called the primary SMTP address, is stamped on outbound messages.

Posting an announcement is an odd way of doing things, but there you areвЂ¦Д®xchange Online mailboxes can have multiple SMTP proxy addresses (also known as aliases). It seems like they ran into some problems with the original implementation, did some rework, and have launched again in preview. Update (January 25, 2022): Microsoft has reannounced this feature.
