Hi @阿巴阿巴 OuO
Teams tag is mainly focused on the general issue of Microsoft Teams troubleshooting. According to your description, your question is not in our support scope. Thanks for your understanding and patience.
The following suggestion is for your reference:
- Check your network connection: Make sure your network connection is stable. You can try restarting your router and Xbox console.
- Delete and re-add your account: Open Settings > Accounts > Delete Account, select your account and delete it. Restart the Xbox console, then re-add your account: Press the Xbox button > Sign in > Add New Account, enter your Microsoft account information.
- Check your Microsoft account status: Try to log in to your account on account.microsoft.com and xbox.com to make sure there are no problems with the account.
- Update your security information: Update your security information on account.microsoft.com: Security > Advanced Security Options, make sure all information is up to date.
If these steps still don't solve the problem, you need to contact Xbox Support for more help.
