Error Message: "Security Certificate Could Not Be Verified"

Suddenly, last night, every time a start Windows Mail, I get the error
message "The server you are connected to is using a security certificate
that could not be verified. The certificate's CN name does not match the
passed value." All works fine when I click to continue, but I want to get
rid of this continual error message. Cox Cable claims it is a "Microsoft
Vista server issue." Does anyone here have any info on this or a solution?

I also am experiencing this problem using ATT/YAHOO mail. They also are
telling me that it's a Microsoft isssue. Right now both companies have be in
a "deadly embrace" where a problem that is no fault of my making is being
ignored because neither company wants to take responsibility.

Please advise.

I use AT&T/Yahoo without any such problem.
Perhaps you could let us know which mail servers you are using.
One possible reason for this error is using an older server which is
not meant to be used with SSL.

Hi Gary, here's the link that lists the server information:
http://helpme.att.net/article.php?item=10918

and here's the error message I'm receiving from Windows Mail:

"Your server has unexpectedly terminated the connection. Possible causes for
this include server problems, network problems, or a long period of
inactivity. Subject 'test', Account: 'pop.sbcglobal.yahoo.com', Server:
'smtp.att.yahoo.com.', Protocol: SMTP, Port: 465, Secure(SSL): Yes, Error
Number: 0x800CCC0F"

Email scanning should be turned off in any anti-virus. Also exclude EML
files from the scan. It provides no protection not provided by the regular
resident protection.
Besides that, McAfee and Norton are not compatible with Windows Mail and
Outlook Express and should be uninstalled. The latest version of Trend's
anti-virus seems to be causing problems too.

I'm not using any anti-virus software (other than Windows Defender) and
certainly no email scanning software, anti-virus or otherwise.

Windows Defender is antispyware, not antivirus.

Have you ever had a Norton or McAfee antivirus program on that computer,
even a trial version? Their uninstall programs often fail to remove the
parts
of those programs that cause problems in Windows Mail.

Also, does your list of installed programs include either the Google Toolbar
program or the SMS Desktop program? If it does, uninstall them, since they
also cause problems in Windows Mail. A web site that offers to let you do
a Google search is not a problem.

No, when I moved from XP to Vista (full install, not upgrade) I intentionally
insued that I didn't install any anti-Virus software, precisely to avoid
these and other types of problems that they caused in my XP installation.
Also, no SMS software ever installed, either.

The only Google stuff I have is Google Earth and Google Updater

Hmmm, that error message says nothing about a security certificate
error, which I thought the original problem was.

That error message is typically caused by running a non-compatible
antivirus program, but I see you stated in a later post that no
antivirus software is or was installed.

The only suggestion I have is to delete that account, restart Windows
Mail, then recreate the account. There is a possibility that the account
became corrupted for an unknown reason.
If no improvement, you might as well try upgrading to WLM:

Here's the link to the SSL error dialog box that precedes the text errr
message.
http://i276.photobucket.com/albums/k.../SSL_Error.gif

The test error message occurs if I press the "No" button. Otherwise, if I
presss the "Yes" button, Windows Mail sends the mail item.

Just to clarify again, this only started happening today after being
required to use the SSL configuration by ATT/Yahoo.

Late News!
Your suggestion for recreating the account seems to have been the ticket. As
soon as I did and tried sending again, everything went swimmingly.

I can only conjecture that since the Account was originally a non-SSL setup
that this, somehow???, may have had conflicting cert information; whereas,
creating a new Account somehow put everything together correctly?

Anyway, thanks all for your patience, life is once again ... good.
