Hello Richard,
Thank you for reaching out to the Microsoft Community and I'll be glad to assist you today.
Before you look to reset your password, double-check that you are using the correct email address when logging in.
When it comes to password resets, Microsoft has a fantastic support article that provides all the steps. You can find it here: https://support.microsoft.com/help/475c9b5c-8c2...
If this is a personal account, please use the following link to reset the password: https://account.live.com/ResetPassword.aspx
If this is a work or school account, please use the following link to reset the password: https://passwordreset.microsoftonline.com/n/pas...
(Use an incognito mode/ private browsing mode and try to reset your Password)
Let me know if you need more help.
Best regards,
Gunasekar N
