Hi @Kelly, Jimmy R ,
Before going further, could you please collect the build number of your Outlook via File > Office Account > About Outlook? Please make sure you have upgraded your Outlook to the latest version.
As I know, uninstalling repairing Office usually can fix feature-related issues but might not initialize and fix issue related to your Outlook files and settings. Usually
corrupted Outlook profile would lead issues like this, so please try creating and using a new Outlook profile via Control Panel > Mail > Show profile and see if there is any difference.
Outlook 2016: Out of memory or system resources. Close some windows or programs and try again.
Create an Outlook profile
If the issue still continues, there could be some add-ins, custom settings, registry keys in your Outlook client that cause this issue, so it is suggested to start your Outlook in safe mode (Press Win + R, type “outlook /safe”, press Enter.) and see if the issue continues.
Any update, please feel free to post back.
