Connectivity or browser issues
  • Open your AT&T Mail in a different web browser. For example, if you normally use Google Chrome®, try Firefox®.
  • Verify that your browser accepts cookies. Then, clear your cookies and cache. You’ll find this info in your browser's Preferences, Settings, or Options menu.
  • Enable JavaScript, and make sure it’s up to date. You’ll find it in your browser settings or options.
  • Disable browser tools or add-ons to see if they’re causing issues with email access.
  • Enable Adobe Flash Player, and make sure it’s up to date.
  • Check your firewall, antivirus, and anti-spyware settings. Sometimes they conflict with email and web browsers. Disable them one at a time and try accessing your email. Don't forget to turn them back on once you know they aren’t causing the issue.

Troubleshoot your email programs or apps

Heads up: We’re upgrading our email security. If you get your email through an email program (sometimes called an email client) or app, be sure you’re all set for the changes. Learn more about the security upgrade.

  • Check to see if you have messages in your outbox folder. If so, remove them and try to send a new message.
  • Review common email error codes for steps to resolve them.
  • Make sure you have the correct email client settings.
