IMAP / SMTP Rejecting Login Credentials with Outlook

Over the last 48 hours I have been experiencing some issues with signing into / retrieving from my ATT.NET email account. I have noticed that my iPhone was coming up with rejected credentials even though I hadn't updated my password at all. I deleted and restored that account on the iPhone and changed the password with ATT.com. I am now trying to update the login information with Outlook and can't even get signed into the IMAP server. I am using the new password and the same server settings I have used for some time. Looking on these forums, it seems that there have been issues recently with getting authorized. What is the problem here?

We're here to help get you logged in, @nocigar_1!

 

Just to clarify, what is the exact type of Outlook you are using for your phone? Depending on the application, you may need to look into Open Authentication or Secure Mail Key.

 

Open Authentication is a security measure we put in place that encrypts your e-mail and password when using 3rd Party Applications. We have an article regarding OAuth that states what applications work with this security system.

 

If the version of Outlook you are using is not in that list, you will need to Create a Secure Mail Key. This is a security measure that encrypts your password, and you are able to create and manage it via myAT&T.

Let's see if we can get your email back up and running, @Mrscruples.

 

Here are the email server settings that you will need to use for your email.

 

Also here is more information about the Secure Mail Key. This is a 16 digit passcode that you will use instead of your current password. This protects against hackers and fraudsters.
