Hello, I'm Quinn and here to help!
May I know what type of account you're trying to sign in with?
- Personal Microsoft account (e.g. Outlook.com, Hotmail)
- Work or School account (company or university email)
Are you able to log into this same account right now on a phone or another computer?
Additionally, could you describe what you see on screen when this happens, or share a photo if possible? This will help me understand exactly where in the process you're getting stuck. Thank you.
