The Meeting Add-In is enabled in Outlook, but the button to create a new Teams meeting is missing.
The mailboxes are hosted on-premises and there is an Exchange hybrid. The issue exists since 28.02.2021, after an update of Teams on both terminal servers.
Checked and the calendar function is not available in Teams. It was not available in the past as well.
The issue doesn't exist on Windows 10 computer.
Error message while running Sara tool: "Microsoft Teams is not installed".
But I noticed that the add-in in Outlook refers to / AppData / Local / Microsoft / Teams and not to / AppData / Roaming /.
I also deleted this folder. And then restarted Teams and Outlook. A new Teams folder has been created under Roaming / Microsoft, but the add-in still refers to Local, even if there is no longer a Teams folder there.

Created a new Outlook profile, but it didn't solve the issue.
