while registering Teams, it asks me over and over again for a phone number

Hello,
I try to set up teams, at a certain point after entering the passwort it asks me to enter a phone number. I do so, i recieve a 4 digit code. I enter the code and it asks me to enter the password again. I do as prompted, after that it opens up again the phone number screen and prompts that the phone number has been used allready and i shall enter another phone number. If i do so this loop starts all over again. What can i do? Standart problem solving issues such as emptying the cache and reinstalling the app has been done allready.

Hi @AutohausMayer-8082 ,

Good day!

What’s the type of your account? Is it a personal account or working/business account?
Could you share a screenshot of the warning message?

Based on my tests, if you use a phone number which is already registered by another account (such as at*@.com in the following image), you’ll receive a warning message as below:
111230-image.png

Then, please check if the account (at*@.com) is registered by yourself. If it is, you could try logging in with your phone number like +201 *, and you can release your phone number by changing the phone number associated with your Microsoft account. After that, associating this phone number with your current account.

If this account is not yours, your phone number should be used by other people. A new phone number is neccessary.

Besides, to determine if this problem is caused by desktop client, it is suggested to log in Teams web client and observe the result.

Best regards,
Lou
