From your post, I understand how frustrating it is when you can’t access your Outlook account at all, even after resetting the password.
Have you already tried the Q&A Assist suggestions yet? If yes, what happened? In addition, please try the following:
1, Check if you can sign in on the web
This helps determine whether the issue is account‑level or app/device‑specific.
- Open a browser on your desktop or a mobile browser in desktop view and go to https://outlook.live.com
- Open an InPrivate / Incognito window
- Try signing in only on the web first (do not open the mobile app yet)
- If web sign‑in fails > the issue is likely account/security related
- If web sign‑in works > the issue is likely with the Outlook apps
2, Check for a security verification loop
If you see behavior like:
- being sent back to the sign‑in page,
- repeated prompts to verify identity,
- or no clear error message,
this can indicate a temporary security hold after a password reset.
In this situation, you should:
- Wait at least 24 hours without further sign‑in attempts
- Then try again using one device only, starting with web sign‑in
3, If web sign‑in works, reset the Outlook mobile app connection
Only do this after web access is confirmed.
- Open Outlook mobile > Go to Settings > select your account
- Tap "Delete Account" > Restart the phone
- Add the account back and sign in again
Please feel free to let me know how it goes. I truly appreciate your patience and understanding.
