Outlook 2016 problems

As suggested by Appleoddity, the first step is to disable all your add-ins to determine whether the issue is caused by a problematic add-in.

If issue still continues when all add-ins are disabled, then you can try renaming the following \Outlook registry key to \Outlook-1 when Outlook is closed:

Computer\HKEY_CURRENT_USER\Software\Microsoft\Office\16.0\Outlook

Then, start Outlook and create your new profile to test it. When you start Outlook in safe mode, most of the customization settings are disabled, and these customization settings are stored in the \Outlook registry key. If it doesn't work, you can just renaming the newly generated \Outlook key to \Outlook-2, and then rename the \Outlook-1 key back to \Outlook.
