스마트폰과 태블릿에서 Microsoft Teams를 플랫폼 전반에 걸쳐 접근하고 사용하기
I have inquired with this issue to IT deparment today, and they also replied that they are not able to solve with this problem. It doesn't work with mobile devices just beacause of certification problem. I still cannot contact with my colleagues outside of the office and I have suffered with this issue for couple of weeks :(
