Managing personal Outlook.com account settings, security, and privacy
Hello,
Could you please check whether you encounter the same error when signing in to Outlook.com with your Microsoft account in a private browsing window?
- Open an InPrivate window in Microsoft Edge or an Incognito window in Google Chrome. (CTRL + SHIFT + N)
- Go to https://outlook.live.com/ and sign in using your Microsoft account and new password.
- Check whether your new password is accepted.
If the new password works in a private browsing window, cached data or previously stored cookies may be interfering with the sign-in process. Clearing your browser's cache and cookies for all time may resolve the issue.
Let me know if you still need more help.
