Same problem, also terminal suggest actions do not work!

Problem solved! I downloaded beta version of Outlook 16.58.22010406 and it works. In Outlook: Tab ,,Help" Choose ,,Find update" Choose ,,Advanced settings" Choose ,,Beta chanel" and agree with Terms and conditions Program find new beta version and you will instal it After this you can return back to ,,Alfa chanel" and wait for next standard update.
