The Outlook window closes, but the application continues to run when you try to exit Outlook (914909)

RESOLUTION

Important If your computer is on a corporate network, contact your Desktop or your Microsoft Exchange Server support team before you disable any add-ins in Outlook, especially antivirus add-ins.

To determine which add-in is preventing Outlook from closing, follow these steps:

1. On the Tools menu, click Options, and then click the Other tab.
2. Click Advanced Options, and then click COM Add-ins.
3. If COM add-ins are listed, note them, and then click to clear the check box that is next to one add-in. Click OK.
   
   If no COM add-ins are listed, go to step 6.
4. Exit Outlook, restart it, and then exit it again. Then verify whether the application closes correctly. To do this, examine the notification area to see whether the Outlook icon stays there for a long time. Alternatively, look in Task Manager for instances of Outlook.exe after the Outlook window closes.
   
   Note In Task Manager, Outlook.exe is found in the list on the Processes tab.
5. Repeat steps 3 and 4 to continue disabling COM add-ins until Outlook closes correctly.
6. If no COM add-ins are listed, click Cancel to close the COM Add-ins window.
7. Click Add-in Manager on the Advanced Options window.
8. Verify that only the default add-ins that are listed in the More Information section are in the list. If non-default add-ins are present, note them, and then click to clear the check box next to each non-default add-in. This action disables the add-in.
   
   Note If there are several non-default add-ins in Add-in Manager, disable them all at the same time.
9. Exit Outlook, restart it, and then exit it again. Then verify whether the application closes correctly. To do this, examine the notification area to see whether the Outlook icon stays there for a long time. Alternatively, look in Task Manager for instances of Outlook.exe after the Outlook window closes.
   
   Note In Task Manager, Outlook.exe is found in the list on the Processes tab.
10. After all add-ins have been disabled, and after Outlook is restarted and closes correctly, enable each non-default add-in one at a time. To do this, exit Outlook, restart Outlook, enable an add-in, and then exit Outlook again.
    
    This procedure may help identify which add-in is not working correctly with Outlook. After you identify the add-in, contact the add-in's manufacturer. A fix for the problem may already be available. Alternatively, the manufacturer may be able to build a fix.
