Kein Teams Meeting aus outlook

Guten Tag, Ich kann aus Outlook zu keinem Teams-Meeting einladen. Ich erhalte folgende Fehlermeldung: 

Woran liegt das? Ich bitte um rasche Rückmeldung. Vielen Dank. Gruss Thomas

Hello, first try and sign out manually from the top right corner in Teams. Then right click on the Teams icon in the taskbar and Quit Teams. Finally sign out of your Outlook desktop as well (File - Office Account) and quit all Office apps including Outlook. Then start Teams and sign in followed by Outlook desktop. It should work now as long as the add-in is enabled in your Outlook settings and you have a subscription that includes Teams.
