Need help sign out problem

This happened to me after a power outage, and I just fixed it. Went to network settings, while signed out, entered my WiFi password, then went to sign in again. It thhen asked for my Microsoft account password, input that, and signed in. Still on after a
few minutes so hopefully this helps you

I have the same issue. Just started. I sign in and then it immediately signs out. Sign in and immediately signs out.

Hi,

The login credentials of your Xbox profile and your Windows 10 user account, the date and time settings of your device, and updates available for the Xbox app and the Windows 10 computer are some factors that we have to consider when troubleshooting issues
signing in to the Xbox app on Windows 10. Answer the following questions and we'll provide you a number of solutions to resolve this issue:

• You've mentioned that you're not able to sign out, are there any error messages you're getting when you click
  Sign Out?
• Have you made any changes to your device before encountering this issue?
• Is the Microsoft account currently signed in to the Xbox app the same with the Microsoft account you're using on your Windows 10 device?

In the meantime, we recommend running the Windows apps troubleshooter provided on this

link. This can help in resolving issues regarding applications downloaded from the Windows Store.

If the same instance occurs, kindly follow the steps provided on this
link on how to check for updates for apps and games from Windows Store. Search if there are any updates available for the Xbox app.

See

Thank You so much! This helped me with my problem.

Hi,

Try to delete your profile (profile only), clear your cache (3 times), and then download your profile again. See if that solves the issue you're experiencing with signing out everytime you start a game.

To delete your profile (profile only):

Dashboard > Settings > System > Storage > Select your storage device > Gamer Profiles > Delete the gamertag you're having this issue with. Make sure when deleting you select
Delete Profile Only.

Clear your cache (3 times in a row):

Dashboard > Settings > System > Storage > Highlight your storage device and press Y > Clear System Cache > Press Yes. Make sure to do this step 3 times in a row.

Re-download your profile:

Push the middle button on your Xbox 360 controller and go to Download Profile. Enter in your e-mail/password and it will begin to re-download your profile.

Please Note: If you're using 2-Step Verification you will need to use the Application Password that you generated upon setting up 2-Step and not your normal password. This is again, only if you have 2-step verification enabled.
