Using Classic Outlook on Windows for personal email, calendar, and contact management
Hi Jonathan,
I saw your comments in another thread that Kendra posted.
It sounds like you may be dealing with a similar issue. In most of the recent cases, the problem has usually come down to a few common causes:
- A virus or malicious script on a device running the email app that keeps reapplying the changes. That is why running a virus scan can help if this was the cause.
- An active signed-in session in an app, either on one of your devices or on a device the hacker is using. That is why signing out of all sessions and deleting any app passwords can help. But signing out of all sessions can take up to 24 hours.
If the issue is coming from a session on a device you have access to, that is also why I often suggest completely removing the account from all email apps on any devices you can think of. Otherwise, the rules may just sync back across devices again.
