Zoom does not connect anymore to Outlook 365 Mail and Calendar

[dejudicibus]

Since I have updated to the latest version, there is a problem with the integrated synch with Outlook 365 Mail and Calendar. I am not speaking of the Outlook Zoom add-in. When I click on Calendar tab I am requested to sign in my Microsoft Account and a browser windows is launched where I authorize Zoom to my Outlook 365 account. I already did in the past, and it worked. Now I am requested to do it again, but clicking on Authorize does not change the situation. No event appears in the calendar. However the calendar connection is still there because I can see my event in upcoming events and there is no «Add a calendar» link in Home. tab. So, it is a hybrid situation: the connection with Outlook calendar is operative but the calendar is not shown in Calendar tab.
