Using Classic Outlook on Windows for personal email, calendar, and contact management
Hi Lyndsey Turner,
So this might be related to some add-ins in the Outlook client. Here are the steps to check which add-in is causing the problem:
- Click File menu, navigate to Options > Add-in, click Go button next to the Manage: Com-in Addfield.
- Clear all the checkbox of the add-ins to disable them.
- Reopen the Outlook client and select the add-ins one by one to check.

Regards,
