internet security warning: cannot verify certificate

A previous question was presented by someone using Outlook Express but I'm

using Outlook 2007 and having the same problem trying to access AOL emails

every time I open outlook. I get an internet security warning that states

"The server you are connecting to is using a security certificate that cannot

be verified. The target principal name is incorrect. I have the option to

view the certificate and I must click Yes to continue using the server to

obtain my AOL emails. IS there a way to turn this warning off or to turn off

the requirement that I click yes to proceed? Inside the certificate are all

kinds of settings/properties which look like they can be changed like

cross-certificates and OCSP's, none of which I know anything about. I just

want to be able to do something to get Outlook to stop requiring me to click

yes every time I want to check my email from AOL. The certificate itself

from AOL looks up to date. Is there something with AOL I should be doing?

THANKS in advance!!!

The server name does not match the certificate name, possible because the

server's public Fully Qualified Domain Name does not match the name on the

certificate or the server name you use. Without seeing the cert, its hard

to say if you can do anything (like change from using mail.aol.com to

imap.aol.com), generally speaking AOL needs to fix the cert.

So are you using SSL to connect to the mail host? If so, how off is

your time? SSL requires initial handshaking which expires (i.e., the

handshaking needs to complete quickly). I don't recall how long but if

the client and server are different by a few minutes then the

handshaking fails because it thinks the process has already expired.

SSL handshaking expires. The timestamps are used to determine

expiration. So check your date, time, timezone, and daylight savings

settings.
