Microsoft Outlook error with the add-ons

I am also using Microsoft Office Outlook as my email client but never encountered this problem yet. By default, Microsoft Office Outlook already has Microsoft Exchange Unified Messaging and comes pre-installed when you install Microsoft Office Outlook like in version 2007. That’s why I’m not sure if the Microsoft Exchange add-in mentioned in the error message is referring to the same Microsoft Exchange add-in I mentioned or a different add-in.

First, to make sure the error is not just an accident, close Microsoft Office Outlook and restart your computer. Open Microsoft Office Outlook and see if the error will appear again. If the same error popup on your screen, just click Yes to disable the add-in. Or you can also do it manually. Start Microsoft Office Outlook then click Tools and then Trust Center. See image.

In Trust Center, select “Add-ins” on the left panel. Under “Add-ins”, select to highlight “Microsoft Exchange Unified Messaging” and remember its add-in type under Type. In Manage located at the bottom, select the add-in type and click Go. See image.

In “COM Add-Ins”, uncheck “Microsoft Exchange Unified Messaging” and click OK. See image.

Restart Microsoft Office Outlook and see if it works.
