I am having trouble that suddenly all my Microsoft-based apps(Teams, Store, News, WINDOWS-SEARCH) stopped working. I tried tons of solutions that I got from this forum but none of them worked for me So, I decided to ask questions. My internet is fully functioning but all apps shows can't connect to our servers. My date/time is also automatically synchronized. Also I am unable to sign in to my Microsoft account because as I click on add account the grey box appears and disappears.
Please help me out I am so frustrated because my whole college is also based on Microsoft Teams and I am unable to use it's desktop app although web app is functioning properly.
