To Disable Outlook 2016, 2013 and Outlook 2010 COM Add-ins
- Select “COM Add-ins” in the Manage drop-down at the bottom of the “Options->Addins” window and click “Go”. Note: To get to the Options window, click on the File tab first.

Let me know if disabling other add-ins changes anything. If not, can you please provide more details about the version of windows that you're using?
