sbcglobal no longer works in Outlook in Windows 11;

Dear Daniel W,

It sounds like you're encountering an issue with your sbcglobal.net email in Outlook Classic on Windows 11, and you're wondering if AT&T has discontinued support. Let's clarify that for you.

AT&T has not stopped supporting sbcglobal.net email addresses for use with Outlook. Your account should still work. However, there's a very common change that customers need to make, which often resolves these types of connection issues.

What has likely happened is that AT&T, as a security measure, now requires the use of a Secure Mail Key instead of your regular AT&T/sbcglobal.net password when setting up or accessing your email through third-party applications like Outlook. Your usual password will no longer work for this specific purpose.

To get your email flowing smoothly in Outlook again, here's are some steps you can follow:

1. Generate Your Secure Mail Key:
   • You'll need to log into your AT&T account directly through their website.
   • Once logged in, navigate to your profile or account settings.
   • Look for an option related to "Secure Mail Key" or "Generate password for third-party apps."
   • Follow the on-screen prompts to generate this unique, 16-digit key. Make sure to copy it down accurately.
2. Update Outlook with the Secure Mail Key:

• Open your Outlook Classic application on your Windows 11 computer.
• Go to File > Account Settings > then click on Account Settings again from the dropdown.
• Select your sbcglobal.net email account from the list and then click the Change... button.
• In the field where your password is typically entered, paste the 16-digit Secure Mail Key you just generated. Do not use your regular AT&T password here.
• While you're there, it's also a good idea to quickly confirm your server settings, though these rarely change unless you've manually altered them previously:
• Incoming Mail Server (IMAP): imap.mail.att.net (Port 993, with SSL/TLS encryption)
• Incoming Mail Server (POP3): inbound.att.net (Port 995, with SSL/TLS encryption)
• Outgoing Mail Server (SMTP): smtp.mail.att.net (Port 465 or 587, with SSL/TLS encryption)
• Also, ensure that the option "My outgoing server requires authentication" is checked, and "Use same settings as my incoming mail server" is selected.

Once you've updated the password in Outlook to the Secure Mail Key, save your changes, and Outlook should be able to connect and send/receive your sbcglobal.net emails without further issues.

I hope these steps provide some immediate relief and guidance. I recognize the importance of reliable email service, and I'm here to help you through these troubleshooting steps.

Please let me know if you encounter any difficulties during this process, and I'll be happy to assist you further!
