User account from identity provider '' does not exist in tenant and cannot access the apps

Occasional Visitor

Dear Sir,


I am fail to login my team in works suddenly during works. I got the same error on my phone and browser (also incognito mode).


After research, I tried to delete any unused personal groups and  clear the cache files under Teams folder but still no luck.


It will be glad if any suggestion for me to solve this problem. Thanks a lot.
