SYMPTOMS
You may not be able to remove Windows Messaging by clearing the Windows Messaging check box on the Windows NT Setup tab in the Add/Remove Programs tool in Control Panel. When you try to clear the check box, your computer beeps.



CAUSE
This behavior occurs when Microsoft Outlook has been installed after Windows Messaging was installed. This occurs so that Outlook cannot be made nonfunctional by the removal of another program.



RESOLUTION
To remove Windows Messaging, you must first remove Outlook. After you remove Outlook and restart the computer, you can remove Windows Messaging.

If you want to reinstall Windows Messaging, you should do so before reinstalling Outlook.



MORE INFORMATION
Although you cannot remove Windows Messaging, you can still add and remove information services. To do so, click Windows Messaging on the Windows NT Setup tab in the Add/Remove Programs tool, and then click Details.
