Configuring preferences and options in Outlook.com
Dear Ruoer Bei
Welcome to Microsoft Community.
I see that you are now unable to log into your account. If possible, can I ask you a few questions?
- Is the account you are using a Microsoft account or a third-party account?
- Is your account a personal account or a school or company account?
- Have you tried to log in through the Microsoft official website? Is there an error message when you cannot log in?
Here you need to provide a message or error screenshot and feedback to us, and we will follow up after receiving it.
Feel free to post back if you need further assistance.
Best Regards,
Chris.S-MSFT | Microsoft Community Support Specialist
