Accessing Microsoft Teams Free using personal or organizational credentials
Hi! My name is Aj and Im an Independent Advisor here to help! I understand your frustration. Please try to check junk/spam folder, other folders and resending the code again. But if it wont work try to use the "Sign in Helper" tool here https://support.microsoft.com/en-us/account-billing/i-can-t-sign-in-to-my-microsoft-account-475c9b5c-8c25-49f1-9c2d-c64b7072e735
If none of these work you will have to submit the form at https://account.live.com/acsr to prove ownership, since support agents cannot manually send codes. After submission kindly allow 24-48hours for verification.
