If you're experiencing issues syncing your AOL account with older third-party mail apps like Kindle Fire's default mail app or the Mac OS mail app:

•Update the operating system for your device. For instructions, see your device manufacturer.
• Delete and re-add your AOL Mail account in your device's mail app.
• Some older, third-party email apps, that do not use our AOL-branded sign in page, require you to enter a single password for login credentials. In this case, you'll need to use an app password.
• Access your account from the web browser on your device by going to mail.aol.com.
