Resolve email issues

AT&T Mail account and settings

• 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

• 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.

• Open AT&T Mail in a different web browser. For example, if you normally use Google Chrome^®, try Firefox^®.

• 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.
