Unable to sign into Outlook

I set up MAC Address filtering on my AT&T router to stop a stalker from corrupting my computer. Somehow it is happening anyway. I don't know if it is with the assistance of Microsoft or AT&T.

My computer shuts down then tries to prevent me from signing in. I have a bios password. When that failed I couldn't sign into my accounts. I did anyway. Now I can't sign into my Outlook email accounts. I get this error.

Something went wrong

An unexpected error occurred and your request couldn't be handled.

Is it possible for someone to access my computer through the server?

unable to log into Outlook

I just tried using Ubuntu to sign in and got the same error. It is the server. Is it Microsoft's or AT&T. Do I think I'm on AT&T's server but it is someone elses. I don't know.

Someone has been stalking and harassing me for years through my computer. I have done everything to block them but they are able to do it anyway. It has to be the server.

MAC Address filters do not work.

You can google that but that, as a security measure has been ineffective for over a decade.

In another post it sounded like you had an Exchange server.
