Uzyskiwanie dostępu do usługi Microsoft Teams (wersja bezpłatna) przy użyciu poświadczeń osobistych lub organizacyjnych
Hi Marcin,
My name is Didi. I'm happy to help you today.
Sorry to hear you can't log in to Teams. May I know the operating system and version you're using?
In case you're on Windows or Mac, could you try clearing the Teams cache using the instructions for your device outlined in the linked document below and see if there's any difference?
