Managing personal Outlook.com account settings, security, and privacy
Hi, I'm John!
To help narrow down the issue:
Do you currently have full access to your Outlook account (you can sign in normally and see your inbox and settings)? Please check signing in online at https://account.microsoft.com
If you're getting "Too Many Requests” error usually happens if there have been multiple login attempts in a short period of time, and Microsoft temporarily blocks further attempts to protect the account.
The only option for now is to wait for the full 24 to 48 hours for the lockout to clear completely.
To be safe, I recommend the following steps:
Check your account rules and forwarding settings, hackers create rules that automatically forward or delete emails. You can do this in Outlook settings under Mail > Rules and Forwarding. https://support.microsoft.com/office/manage-email-messages-by-using-rules-in-outlook-c24f5dea-9465-4df4-ad17-a50704d66c59
Just to be safe, I’d recommend to sign out everywhere. Visit: https://account.live.com/proofs/manage/additional Scroll down to Sign me out and select "Sign me out".
- After signing out everywhere, please monitor if the issue persists in the coming hours.
And changing your password again and enabling two-step verification if you haven’t already. This will add an extra layer of security to prevent future unauthorized access.
