My free sbcglobal.net email account was hacked and now I can not receive emails, how do I fix that?

Here's the things that I recommend you do and/or check.

• Change your password (and maybe the security questions too, but password is usually "good enough").  Ok, you say you did that.
• Log into your webmail and click gear->settings.  In the webmail settings panel you will see a number of commands on the left.  The ones that need checking are Accounts, Filters, and Blocked Addresses.
• Accounts.  Click that and choose an account to bring up that account's settings panel.  Scroll down the panel to see the Reply-to address and see if it is suspicious.  Blank it out if you don't want that set.  Scroll down further to see the forwarding setting and make sure it is blank or what you want.  When you are done click the Save button to update that account's settings.
• Filters.  Look for suspicious filters and subtle filter names like '.' (a dot).  Remove them and click the Save button.
• Blocked Addresses.  Make sure no addresses are defined who's email you don't want blocked.  Click Save to update those settings.

Thank you so much for these suggestions. I was able to do as you instructed for the Reply to Sender, Forwarding and Blocked messages parts but I could not find anything referring to Filters. So as of now, I still am not receiving any new messages. And now I am getting calls from my friends and family that the hacker is communicating with them via my email, still trying to get someone to send them money. So the hacker has definitely hijacked my incoming emails and somehow routed them to him or herself.

I did not send this to you.  My email was not hacked, it had something to do with the windows

1. account being closed because of something being lapsed .  I have to get a new tax or contract for windows.

Your account was not hacked! 

 Sbcglobal went out of business 20 YEARS ago. AT&T grandfathered sbcglobal.net and SNET.net accounts in  but AT&T then left CT around 3 years ago. They are slowly removing all the old SNET and sbcglobal accounts. What I don't understand is why are people upset that the email address they're using from a company that WENT OUT OF BUSINESS 20 YEARS AGO !!! You are no longer paying AT&T for your DSL internet but expect them to keep maintaining your email address that they were nice enough to allow you to continue using in the first place. Unfortunately, most of the tech support people at AT&T don't realize that AT&T is getting rid of these outdated email accounts. They started doing this in November of 2017. Most likely you had your email incorrectly setup as a POP3 account so you will actually still be able to read your old email. If you have it setup the "right" way as an IMAP account, then your old emails are gone  for good. I say right and wrong because the world started switching to IMAP decades ago so that you could read your email on multiple devices and have them all synchronize. POP3 is really only meant to be read from a single device. If you've ever wondered why your sent mail folders don't show the same emails and when you create a new email folder it doesn't show up on all devices  you are setup using the POP3 standard and your IT guy should be fired! Once again, sbcglobal went out of business in 1998. I think 20 years was long enough to find a new email address! 

Your Windows account was not closed either! That is a common scam that will try to get you to buy or renew your "Windows license". The windows license WILL NEVER EXPIRE!!!
