Send email from or on behalf of an Office 365 group

Outlook on the web for Office 365 Business

Let's say you've set up an Office 365 group called "Leadership Team" and you've been tasked with managing the calendar and correspondence for that group. Occasionally, you'll need to send mail or schedule a meeting and recipients would see that you have sent the mail on behalf of the group.

Alternatively, when sending mail to customers or external users, you might to obscure your name and email address for privacy or other reasons. In this case you replace your name with the Office 365 group name (this is known as send as), and the recipient would only know that the mail came from a company address (such as LeadershipTeam@contoso.com)

A tenant admin must enable group members to have Send on Behalf or Send As permissions before they can send mail using these features. The admin enables these permissions in the Exchange Admin Center.

Here's a summary of how the process works.

  1. Tenant admin grants "send on behalf of" and "send as" permissions to members of the group.

  2. User goes to Outlook inbox or the group space where they have "send on behalf of" and "send as" permissions to send mail.

  3. Recipient sees the following:

    Send on Behalf

    Send As

    The header of the mail states that the mail was sent by you but on behalf of someone elseThe header of the email shows that the mail was sent by the group
