Microsoft 365 and Teams: use my own domain for email notifications

New Contributor

Hi all, I have a problem configuring Microsoft 365 and Teams. My goal is to receive all the Teams email notifications (eg. new scheduled or canceled meeting) on my company email (we have an on-premise Exchange Server). If I add my domain to the Microsoft 365 Admin console, MS creates a new Exchange on the cloud with new mailboxes (eg in which all the Teams email will be sent. If I don't add my company domain all the email will be sent to the default domain. Where am I wrong? Thank you for your help, Paolo

You can add your domain and configure it for Exchange Online, without actually having to create any mailboxes for it. To make sure mail flow is handled correctly (as in sent to the on-premises server), you need to then set the domain as Internal relay:


But in general, if you want to take full advantage of all Teams features, you need to "integrate" it with Exchange:

@Vasil Michev thank you for your reply.

The mailboxes were created automatically by Microsoft 365 when I added users for Teams. I can't delete that mailboxes.

@Vasil Michev ok, I removed Exchange Online and all its dependencies form app enabled on the user and the mailbox disappear. Thank you

@PaoloRedix do your users have calendars in teams if you havn't enabled exchage online for them?
