Problem with adding phone number to MS Teams

Hello! I've downloaded MS Teams application to my computer. It asks me to add mobile phone number. When I receive code I put it into the field it says that this mobile phone number is already in use...

    So I cannot use the same phone number for my personal account and work account?

     

    Regarding error that my account is already set up none of these steps worked for me.

      Adam1 I suggest you follow the instructions provided in the first link to, for ex., create an alias and remove the phone number from the primary account. I would also use InPrivate windows doing that.

       

      Regarding the "Someone..." this can be one of a couple of things, such as a user has signed up for self-service subscription using your domain name etc. Difficult to say with the information provided.
