    For me the issue was caused by Teams Meeting Add-in
    With Outlook open, select File > Options > Add-ins > COM Add-ins > Go
    Then uncheck these add-ins if they are present:
    Microsoft Teams Meeting Add-in for Microsoft Office
    Skype Meeting Add-in for Microsoft Office
    Click OK

    Hope that helps.
