Allow members to send as or send on behalf of a Group

A member of a Microsoft 365 group who has been granted Send as or Send on behalf permissions can send email as the group, or on behalf of the group. This topic explains how an admin can set these permissions.

For example, if Megan Bowen is part of the Training Microsoft 365 group, and has Send as permissions on the group, if she sends an email as the group, it will look like the Training group sent the email.

The Send on Behalf permission lets a user send email on behalf of a Microsoft 365 group. For example, if Alex Wilber is a part of the Marketing Microsoft 365 group, and has Send on Behalf permissions and sends an email as the group, the email looks like it was sent by Alex Wilber on behalf of Marketing.

Important

You can configure Send as or Send on behalf for a given user, but not both. If you configure both, it will default to Send as.
