Give people delegate permissions for a distribution group
If you are an Office 365 admin, you can give people delegate permissions to send email from, and on behalf of a distribution group.
- Log in to your office 365 admin center.
- Click the Admin tile.
- In the Office 365 admin center panel, click Groups.
- In the Groups panel, check the box next to the group you want to add delegates to.
- In the right panel, under Distribution list, click Edit Exchange properties.
- Click group delegation.
- Use the following to help you determine whether you want to assign Send As or Send on Behalf permissions
Send As:
This allows a member of the group to send email as the distribution group address. To a recipient, the From line will display the group name only.
Send on Behalf:
This allows a member of the group to send email on behalf of the group. To a recipient, the From line will display the sender “on behalf of” the group.
To send as the distribution group, you need to show the From field in your email composer. To show the From field in Outlook, open a new email, click Options, and select From.
