I've seen multiple people describe this problem, but have yet to see a solution.
I have a former Skype account that was transferred to Teams. Works fine with the desktop Team software. Trying to get access to it on my Android phone (Android 14). Version 1416/1.0.0.2022415001 is installed. I have attempted logging in both with my username and password (confirmed working by logging in to Teams via a browser on a desktop computer) and with my e-mail address and the code sent to it.
Every time I get this "Sign-In error: Looks like you're not using Teams yet. Check that you've been invited by the org you're trying to sign in to. You can also set up Teams for your org by selecting Create new account."
It seems to recognize that I'm signing in correctly, it just won't connect me to my Teams messages and contacts.
Google AI says "the app is mixing up your personal and work/school accounts", perhaps so, as there is only a personal account and no work/school account at all. I see no option or choice to log in via a personal account rather than a work/school account.
Please help me. I actually do need this for communication with my coworkers when I'm away from the office, it's just not set up as a "work account" or via any kind of "organization". It's just a plain regular microsoft account.
