Do I have to change my Email Address?

So Ive been using my Outlook Account for over 20 years now and in the last few days I noticed, that my Mails are automatically getting forwarded to a shady Mail Address (something like [email protected]). I found that someone created a "forwarding rule" to this Address and immediately deleted it and changed my password. But now I found that there are literally so many people trying to hack me every day because my Email Account seems to be out everywhere somehow. What do i do?
