Teams new registration hasn't been added to your organization's directory

[Palmreh]

Hello, im unable to register new account in Teams with companys email address. I got message "Email address hasn't been added to your organization's directory. Contact your admin or try a different email." Its unclear what I have to do because i got invitation for teams group and from group owner side everything is correct.

@Palmreh Hello, as far as I know that usually shows when a Teams license isn't assigned. Try checking the account to verify if that is the case.
