Trouble Setting Up AT&T Email on iOS and Android Devices - Need Help!

Hello Forum Members,

I'm having trouble setting up my AT&T email on different mobile devices. Despite following the provided instructions, I keep encountering issues and can't get my email to work seamlessly.

Problem Statement: I've tried configuring my AT&T email account on both iOS and Android devices using the IMAP/SMTP settings from AT&T. However, I keep running into authentication errors or constant prompts to re-enter my password, even though I've entered the correct credentials.

Details:

I've carefully followed the step-by-step instructions provided by AT&T for setting up email accounts on mobile devices.
I've tried both automatic setup (using email client settings) and manual configuration (entering server details manually), but neither method resolves the issue.
I've double-checked my username, password, and server settings numerous times to ensure they are correct.
I've also tried disabling any security applications or firewalls that might interfere with the email setup process, but the problem persists.

Can anyone provide guidance or tips on how to successfully set up an AT&T email account on mobile devices? Has anyone else encountered a similar issue and found a solution? I'd appreciate any assistance or advice to help resolve this frustrating situation.

Thank you in advance for your help!
