Hello BearacatTD,
From your description, I understand that ribbon disappears in your Outlook for Mac. Since the ribbon is not in the View menu, you can check whether you can expand the ribbon by pressing Options++R. If convenient, please uninstall Microsoft 365 apps and re-download it again to see the result.
If the issue still persists, to better help you, please provide the screenshot about your Outlook version to me.
Regards,
Seven
