Trouble Setting Up AT&T Email on Mobile: Authentication Errors Persist

Hello Forum Members,

I need some assistance with setting up my AT&T email on different mobile devices. Despite following the provided instructions, I'm facing persistent issues and can't seem to get my email to function smoothly.

Problem Description:
I've attempted to configure my AT&T email account on both iOS and Android devices using the IMAP/SMTP settings provided by AT&T. However, I keep encountering authentication errors or continuous prompts to re-enter my password, despite entering the correct credentials.

Key Details:

• I followed AT&T's step-by-step instructions for setting up email accounts on mobile devices meticulously.
• I've tried both automatic setup via email client settings and manual configuration by entering server details manually, but neither method resolves the issue.
• I've double-checked my username, password, and server settings multiple times to ensure they are accurate.
• I've also attempted to disable any security applications or firewalls that might interfere with the email setup process, but the problem persists.

Could anyone provide guidance or tips on successfully setting up an AT&T email account on mobile devices? Has anyone else encountered a similar issue and found a solution? I would greatly appreciate any assistance or advice to resolve this frustrating situation.

Thank you sincerely for your help!
