outlook 2011 mac keeps asking for password imap

since they are not the ones ATT specifies and IMO there's no guarantee the yahoo settings will last forever for ATT users. I rarely ever recommend using the yahoo settings ( here for pop, here for imap).

For the other server settings in Outlook compare with the settings specified here.

If the account (email) and password are correct and working in the webmail then those should be what you enter in the Outlook settings for that account.

You need to find out whats wrong with your login info first. If you can't log in there's no sense going further. Doing this test verifies the login info without yet involving your email client app (Outlook in your case).

Go to, click the mail icon in the upper right, and log in. First verify your login info by making sure you can log into the webmail with your browser.There's probably something wrong with your settings even if you think they are correct (it's easy to miss or miss-read setting entries like check boxes). I have an Outlook 2011 laying around on my 10.6.7 Snow Leopard Mac (don't use it, I prefer Thunderbird) just for answering questions like this.

Outlook 2011 should work fine on your Mac.
