Hi, I'm John! I will help you with this.
Microsoft Q&A is public, and we can only provide information. It is beyond our capability to assist directly with the account or login-related issues.
Are you signing in with the same email and password you use for the Outlook app on your PC?
If yes, try these steps:
- Clear your browser’s cookies and cache.
- Open https://outlook.live.com/mail again and try signing in. Test signing in to https://account.microsoft.com as well and let me know how it goes.
- If it still says “wrong password,” try resetting your password at https://account.live.com/password/reset
If issues persists, to help narrow things down:
- Does the issue persist even when trying different web browser like Edge?
- Also, just to confirm, are you using a personal Outlook account (like @outlook.com or @hotmail.com) or a work/school one?
