In Outlook, How to grant Send On Behalf Of permission?

Grant Send on Behalf of via Active Directory Users and Computers

This procedure will allow system managers to grant users the ability to send on the behalf of other users:

1. Log onto the server running Exchange.
2. Run Active Directory Users and Computers.
3. Find the user's account that you want to be able to send on behalf of, and open up the account properties.
4. Select the "Exchange General" tab.
5. Click [Delivery Options...]
6. Click [Add ...] and add the user (or users) that are to be granted permission to send on behalf of this account.
7. Click [OK] to close the "Delivery Options" dialog.

How to Send a Message on Behalf of Another

To send an email on behalf of another (assuming you have been granted the necessary send-on-behalf-of privilege):

1. Start Outlook.
2. Go to your Inbox.
3. Click [New] to start a new mail message.
4. If the message does not show a "From" field then pull down the "View" menu and check "From Field".

   Note: I have noticed that if you have Outlook set to use Microsoft Word then the "From Field" does not appear in the "View" menu. The work around is to clear the option to use Word (Outlook → Tools → Options → Mail Format → Use Microsoft Office Word 2003 to edit e-mail messages), you will then be able to show the From field, and this remains even if you re-select to use use Word to edit emails.

5. Click [From...] and select the account that you wish to send an email on behalf of.
6. Compose the email as normal.

Note:

• When you try to send the email you will get an error if you have not been granted the necessary send-on-behalf-of permission.
• To the recipient the email will show both the true author and who it was sent on behalf of.
