Using the New Outlook for Mac for personal email and calendar
Hi, @rob murray
First, 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".
Also check the account aliases here: https://account.live.com/SignInPreferences check the recovery email addresses or other verification methods listed there. If possible, add your own recovery method first, then remove the hacker's email address. Microsoft may place the security changes into a 30-day pending period if the security information has to be replaced.
Also check "Manage how you sign in to Microsoft" under your account information and make sure the hacker has not added or changed an account alias.
To help narrow this down:
- Can you edit or remove the hacker's email address there so the security change can start the 30-day pending period?
- Is the hacker's email shown as an account alias, a recovery/security method, or both?
- Do you see any message saying a security information change is still pending?
