Allow members to send as or send on behalf of an Office 365 Group - Admin help

A member of an Office 365 Group who has been granted Send as or Send on behalf permissions can now send email as the group, or on behalf of the group. This topic explains how an admin can set these permissions in the Office 365 admin center or by using PowerShell. Learn more about Office 365 Groups.

For example, if Allie Bellew is part of Training Office 365 Group in your organization, and has Send as permissions on the group, if she sends an email as the Office 365 Group, it will look like the Training department from your organization sent the email.

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