root certificates

I did a google search on this topic and found a number of hits. Maybe one of those hits will provide you with a solution.

Had the same problem, come to find out ATT has changed their email setting again...

"Note: AT&T's POP/SMTP settings have recently changed to inbound.att.net and outbound.att.net. However, if you are using the old settings, they will continue to work."

Work until this week I guess...

Here is the link and the new settings:

Email > Top Solutions > Email server settings (POP and SMTP)

Email server settings (POP and SMTP)

The following mail server settings will work with all AT&T email domains: @ameritech.net, @att.net, @bellsouth.net, @flash.net, @nvbell.net, @pacbell.net, @prodigy.net, @sbcglobal.net, @snet.net, @swbell.net, @wans.net.

Note: When updating the secure server settings, check the SSL check box first and then update the port number if necessary.

Thank you for the information from the ATT web site. It worked for me.

Looks like it worked for me as well. You would think ATT would send you an email when they make a change like this.

Thanks, this saved me a lot of time tracking down the solution myself!

I had the same problem with Entourage 2008 on my black MacBook. Updating my sbcglobal.net accounts to the new inbound/outbound att.net settings fixed the "correct root certificate is not installed" problem. I spent way too much time researching this; just unbelievable that att never contacted its customers with this change.

I am having the same problem--made the changes suggested, but still can't get it resolved...

I had the same problem, intermittently anyway. In speaking with an AT&T rep I learned that the problem may go away if you use your browser to log into your mail account periodically. If you don't log in that way then after a period of time you will be given one of those jumbled passwords on your monitor that you have to type into a text field in order to proceed. Since this cannot be done with Entourage, that's where the glitch may originate: Entourage receives the query to type in the password jumble and chokes on it because it isn't a web browser. The fact that you get one of these text jumbles when using your borwser indicates it's been a long time since you logged in with your browser. Try logging in that way and see if the problem goes away.

BTW, I tried changing my server settings as indicated in the post by iChop (above) but it didn't help. I also confirmed with the AT&T rep that the previous settings I had were correct pop.att.yahoo.com and smtp.att.yahoo.com. HTH.

Hello iChop,

Thank you very much for your reply to Kevin Bean -- that answer was just what I needed! Changing the old POP and SMTP from names with Yahoo in them to inbound.att.net and outbound.att.net immediately fixed my difficulty in Entourage. (aside: looks like AT&T is dumping Yahoo too.)

They should change your rating from 'Helpful Answer" to "Correct Answer"

thanks again, DorothyDotts

Worked for me too!

Thank you, thank you, thank you!!

Thanks a lot for the tip! It worked like a charm...

I just called AT&T support to help me with my Entourage account settings so that I could get rid of the error boxes that say I need the correct root certificates. They want to charge $15/ mo for 1 year or $49 for one time fix.

I just got the same message. My email account is with Verizon, I use Entourage on my desktop. As far as I know, Verizon has not changed their settings recently. I rechecked my settings anyway (similar to what is described above with the POP and SMPT servers) and everything was indeed correct. The only thing I noticed was that "Override default POP port" was not selected with a check-mark. I selected it, clicked OK, but I still couldn't send out an email. I rebooted Entourage. That POP setting reverted back to unselected. I was then able to send emails again...

Weird.
