BellSouth email addresses are still used by many longtime customers, but accessing them can sometimes be confusing because BellSouth email is now handled through the AT&T Mail system. As a result, users may experience problems such as BellSouth email not working, login errors, forgotten passwords, missing emails, sending failures, or synchronization problems in Outlook, Apple Mail, Gmail, iPhone, and Android.
The good news is that most BellSouth email problems can be fixed by checking your account, browser, internet connection, and email settings in the right order.
This guide explains the most common BellSouth AT&T email problems and provides easy fixes you can try before seeking additional support.
Before changing your email settings, make sure your device has a stable internet connection. A weak or interrupted connection can prevent your BellSouth inbox from loading or stop messages from being sent.
Try opening another website in your browser. If other websites are also slow or unavailable, restart your Wi-Fi router or switch to another network.
If the internet works normally but BellSouth email does not, continue with the following troubleshooting steps.
One common reason for BellSouth email not working is attempting to access the account through an outdated or incorrect login page.
Your @bellsouth.net address is supported through AT&T Mail. For web access, use the official AT&T Mail support page and follow the current sign-in instructions rather than relying on old BellSouth login pages.
Enter your complete BellSouth email address and password carefully. Watch for:
Incorrect capitalization
Extra spaces
A mistyped email address
An outdated saved password
Browser autofill entering old credentials
If you can sign in successfully through the web but cannot access email through Outlook or your phone, the problem is likely related to your email app's configuration.
If your password is rejected repeatedly, don't keep trying random passwords. Multiple unsuccessful attempts can make account access more difficult.
Use AT&T's official account recovery and password-reset process to create a new password. After resetting it, test the new credentials by signing in through the web before updating your email apps.
If webmail works with the new password but your email application still displays an authentication error, you may need to update the app's password or use a Secure Mail Key, depending on the application and authentication method.
AT&T specifically recommends a Secure Mail Key for email programs that don't use OAuth. AT&T LSREG
If you can receive messages but cannot send them, check your Outbox first. A message stuck there can sometimes prevent additional messages from being sent.
AT&T recommends checking your internet connection, removing messages stuck in the Outbox, confirming the recipient's email address, and checking whether the message is too large. AT&T
You should also verify your outgoing mail server settings if you're using an email application.
For IMAP accounts, AT&T currently lists:
Incoming server: imap.mail.att.net
Incoming port: 993
Security: SSL
Outgoing server: smtp.mail.att.net
Outgoing port: 465 or 587
These settings apply to @bellsouth.net addresses as well as several other legacy AT&T email domains. AT&T
If new messages aren't appearing, don't immediately assume that your account is broken.
First, check your Spam or Junk folder. Then review your blocked addresses and email filters. A legitimate sender may have been accidentally blocked, or a filter may have moved incoming messages into another folder.
AT&T also recommends checking your account settings and sending yourself a test message. If the test message doesn't arrive, investigate the Inbox, Spam folder, and any delivery-error notifications. Yahoo Help
Also ask the sender to confirm that they used your complete and correct @bellsouth.net address.
Third-party email applications require correct server settings. If you recently changed your password, upgraded your email application, or started receiving authentication errors, check your account configuration.

AT&T notes that recent security changes can require email-program settings to be updated, and some applications may require a Secure Mail Key. AT&T
Avoid copying server settings from random websites because outdated configurations can cause authentication and connection errors.
Sometimes the email account is working, but the browser is causing the problem.
If your BellSouth inbox won't load, try:
Sign out and reopen the browser.
Clear your browser's cache and cookies.
Make sure cookies are enabled.
Update your browser.
Try another supported browser.
Sign out of other active email sessions and try again.
AT&T recommends switching browsers and clearing cookies and cache when browser-related problems prevent access to AT&T Mail. AT&T LSREG
A temporary browser error can also occur when an account is accessed simultaneously from multiple browsers or devices. Yahoo Help
If your BellSouth messages aren't syncing on a smartphone, first check whether you can access the account through webmail.
If webmail works, review the email account configuration on your phone. For apps that don't use OAuth, AT&T says you may need a Secure Mail Key. Certain current mobile apps, including Apple Mail, Outlook Mobile, Yahoo Mail, and Gmail on supported devices, use OAuth and don't require a Secure Mail Key. AT&T
You can also remove and re-add the account if the existing configuration has become corrupted. Before doing this, make sure important messages are safely stored on the server.
Another issue that is easy to overlook is account inactivity. AT&T states that a mailbox that hasn't been used for 12 months can be considered inactive and its mailbox contents may be deleted. An inactive mailbox may be recoverable for up to three years by signing in, but the original content and settings won't necessarily return. AT&T LSREG
If you haven't used your BellSouth address for a long time, this could explain why you're having trouble accessing older messages.
Unexpected missing emails, messages sent without your permission, spam being sent from your address, or an unfamiliar display name can indicate that your account may have been compromised. AT&T specifically recommends checking for signs of hacking when these symptoms occur. AT&T
If you suspect unauthorized access, change your password, review account settings, check forwarding and filtering rules, and secure the account before continuing normal email use.
When BellSouth AT&T email is not working, the problem is usually related to login credentials, browser settings, email filters, internet connectivity, or outdated app configuration. Start with the simplest checks: confirm your internet connection, sign in through the official AT&T Mail service, verify your password, and check Spam, filters, and blocked addresses.
If you're using Outlook, Apple Mail, Gmail, or another email application, carefully verify the current AT&T server settings and authentication requirements. For many older or non-OAuth applications, a Secure Mail Key may be necessary.
