Hi Happy new year to all of you. Today i tried to use that new functionality that was implemented in december 2021 by Microsoft. I should now be possible to chat and call with external users who have no organisation account and do not work in an other company if i am informed correctly. I tried it and i can now chat between my private teams account and my organisational Teams account but i can not call or videocall between them. I find no policy where this is denied / defined. I checked our global meeting policy, call policy and teams policy. Does someone know what kind of policy / settings this is or is this right now not possible ? Thank you for your help!
