Microsoft Office Outlook error has occurred

Asked By 20 points N/A Posted on -


Recently, I got the following error message when I uninstalled McAfee and installed Norton 360 and attempted to open Outlook. What is the problem?

How can I uninstall the add-in properly so that I may run my program?

I would appreciate your help.


The Add-in McAfee Anti-Spam

Microsoft Office Outlook

The Add-in “McAfee Anti-Spam”

(c:PROGRA~2mcafeemskmskolplg.dll) cannot be loaded and has been disabled by Outlook.

Please contact the Add-in manufacturer for an update.

If no update is available, please uninstall the Add-in.
