Symantec Error in Outlook

From McCombs Wiki

After UT switched from using Symantec Anti-Virus to using Microsoft Forefront, many users received an error when they opened Outlook. Although you can click OK and use Outlook as usual, the message appears every time you open Outlook.

To Eliminate the Error Message:

1. Click OK to close the error message.
2. From the Tools menu, select Trust Center.
3. Click Add-Ins.
4. From the Manage drop-down list, select Exchange Client Extensions and click Go.
5. Uncheck the Symantec check box (the specific title depends on which product you had installed) and click OK.
6. Exit Outlook and open it again. The message should no longer display.
