Managing personal Outlook.com account settings, security, and privacy
Hi T H,
Welcome to Microsoft Q&A forum.
I’m really sorry you’ve been stuck in this loop. I understand how exhausting it is when you know you’re using the correct password, yet the sign-in or password reset keeps failing.
Based on what you described, the two messages usually point to a stale/invalid browser session (“session expired”) and/or a temporary security lock triggered by repeated sign-in attempts (sometimes caused by saved credentials or background retries on other devices).
Please note that this is a user-to-user support forum. Moderators, contributors including external Microsoft employees cannot directly intervene in Microsoft product features or access back-end systems. Our role is limited to providing technical guidance on reported issues, requests, or ideas only.
Please try this “clean” recovery flow:
1. Stop background retries first
- On all devices/apps where those accounts are added (Outlook app, Mail app, old PCs, tablets), please sign out or temporarily remove the accounts.
- This prevents silent retries from continuing in the background.
2. Reset from a fresh private session (don’t reuse old links/tabs)
- Open an InPrivate/Incognito browser window and go directly to the official reset page:
- Then complete the reset. Using a private window and starting from the official page can help avoid the “session expired” loop caused by cached cookies/sessions.
3. Clear saved sign-in data (if you’re on Windows)
- If you use Windows, check Credential Manager and remove saved Microsoft/Outlook sign-in entries.
- This can prevent older saved credentials from repeatedly triggering the “too many attempts” protection.
4. Try signing in once via Outlook on the web
- After resetting from a clean session, try signing in at Outlook on the web.
- If the “too many attempts” message appears again, avoid repeated retries in a short time, as that can keep the lock active.
If it’s still happening after trying in a clean session, please get back to me.
