Why is my AT&T email not working only on Windows?

Desktop clients utilize IMAP/SMTP protocols that require distinct authentication (Secure Mail Key) compared to browser-based access. Standard passwords often fail in the Windows Mail app due to modern security handshakes.

Does clearing the cache delete my actual emails?

No. Emails are hosted on AT&T’s cloud servers. Clearing the local cache only removes temporary files from your workstation; once you re-sync, your emails will reappear from the server.

What is the difference between a password and a Secure Mail Key?

A password is for web portal access; a Secure Mail Key is a dedicated 16-character application password designed to authorize third-party software like Windows Mail without exposing your primary account credentials.

Can I recover my AT&T account without a phone number?

Yes. You can use verified security questions or a secondary recovery email address. If you are trying to sync your mail to receive a Facebook reset code, ensure your recovery settings are fully updated in your AT&T profile.

How often should I sync my email?

For real-time notifications, set sync to 'As items arrive.' For users with limited bandwidth or intermittent connectivity, a 15 or 30-minute interval is recommended for better stability.
