How to Remove "On Behalf Of" in Outlook

In the Microsoft Outlook application, you can grant other users access to your email account using the delegates feature. When a delegate sends a message from your account, the words "On Behalf Of" appear at the top of each outgoing email. To get rid of this and make it appear like the account's owner is sending the message, a server administrator must manually grant the delegate "Send As" permissions.

Step

Log on to your PC server with an administrative username and password.

Step

Open the "Start" menu, go to the "Programs" list, expand the "Administrative Tools" folder and click on "Active Directory Users and Computers."

Step

Go to the "View" menu at the top of the window and check the "Advanced Features" option.

Step

Double-click on the username for which you want to set up sending permissions.

Step

Go to the "Security" tab at the top of the pop-up window.

Step

Press the "Add" button and enter the username of the individual for whom you want to be able to send messages without the "On Behalf Of" text.

Step

Check the "Allow" box for the property labeled "Send As." Make sure none of the other property boxes are checked.

Step

Click "OK" to save the settings.
