I have a client who has been an AT&T U-verse customer for many years. In fact, her email address dates back to the SBC Global (a successor to one of the baby-Bell) days.

I was trying to set up Outlook (from a download of the download of the Microsoft Office 2021 suite) with access to her SBC Global email address. Documentation I could find suggested to use the servers imap.mail.att.net and smtp.mail.att.net, using the usual port numbers and SSL/TLS authentication. I could not get this to work and to get Outlook to make an authenticated connection to the IMAP server. The AT&T support agent found evidence of the fact that only Outlook 2019 and older are compatible with the Yahoo/AT&T IMAP and SMPT servers. Could this be true?

Yes, the answer to the question could be true. I'd wonder if the issue is Webmail, only accessible through a browser like Hotmail and Outlook.com [both now merged into outlook.live.com]. I'd try installing the free Thunderbird to check it if works.

Most e-mail providers now require you to generate an app password, separate from their normal user password, in order to access e-mail services. This is an extra layer security, much like one-time 2FA texts.

It turns out it’s AT&T’s issue, or maybe Yahoo’s. On the AT&T website we can set up a “secure mail key,” which all client software has to use. You can set up multiple, auto-generated secure mail keys, using one for each email client, or share them between multiple clients. They can not be retrieved. A new one has to be made if the previous one is forgotten.

At least on my Mac I was able to authenticate my client’s email account in the Mail app. I do suspect that with Outlook on Windows it will be the same.

This is the answer. I’ve set up outlook 2021 with a yahoo email before. Generate an app specific password and you will have no issues setting it up.
