INSTRUCTIONS & INFO

Troubleshoot your email account, settings, and apps

AT&T Mail account and settings

  • Check your email size. If your email is too big, it may not be sent.
  • Be sure you’re using the correct recipient email address. If not, you may get error messages like Failed Delivery or Problem Found - Message Not Sent.
  • Try signing out of your email account and signing back in.
  • Check your spam folder for missing emails.
  • Review your settings. Select the gear icon, then check:
    • Blocked addresses: Be sure you aren’t blocking addresses you want to get email from.
    • Filters: Are emails going to the correct folder?
  • Check if your account has been hacked. Your account may be compromised if you’re:
    • Missing emails
    • Receiving emails from your own email address
    • Getting complaints about spam coming from your email address
    • Seeing a display name that's different from the one you set up

Email programs and apps

  • Make sure you have an active internet connection.
  • See if you have a message in your Outbox folder. If so, remove it and try to send a new message.
  • Review common email error codes and steps to resolve them.
  • Make sure you are using the correct email client settings.
FYI: We’re upgrading our email security. If you get your email through an email program or app, be sure you’re ready for the changes. Learn more about the security upgrade.

Check for browser issues

  • Open AT&T Mail in a different web browser. For example, if you normally use Google Chrome®, try Firefox®.
  • Verify that your browser accepts cookies. If so, 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’s Settings or Options menu.
  • 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 updated.
  • Check the settings of your firewall, antivirus programs, and anti-spyware software. They can cause a conflict with email programs and web browsers. Disable them one at a time and try to access your email. Don't forget to turn them back on once you know they aren’t causing the problem.

Fix sign-in issues

Here are some common error messages—and what may be causing them.

Your password doesn’t work on your smartphone

Did you recently change your email password or link your email to your AT&T user ID? Update your password on all your devices to access your email. Get more info about shared passwords.

We can’t find that ID and password combination

Make sure you entered your ID and password correctly. For your protection, we may lock your account after too many sign-in attempts. If this happens, wait an hour or reset your password.

Your account isn't active

Did you get a notice from AT&T Internet Services Security? If so, your email account was flagged for sending spam. Your email account security may be at risk. To reactivate your account, contact us.
