Vista secure email problem: Cannot connect to email server when specific digital id is installed

I imported a personal digital certificate from an XP machine running
Outlook Express onto my Vista Home Premium (32 bit) laptop. With the
certificate installed, Windows Mail instantly (either when mail is
started, or when send/receive is clicked) gives the error message below:

"Your server has unexpectedly terminated the connection. Possible
causes for this include server problems, network problems, or a long
period of inactivity. Account: 'attmail', Server: 'pop.att.yahoo.com',
Protocol: POP3, Port: 995, Secure email: Yes, Error Number: 0x800CCC0F"

I have checked all settings and they all appear to be the same between
both machines. Both are running IE 7 as well. Both also have the same
version of AVG, although I later disabled AVG on the Vista machine, just
to be sure it had nothing to do wth the problem.

Additional interesting info: 1. I have several digital certificates
installed. Only this one is giving me a problem, and only on Windows
Mail on the Vista machine, not on the XP machine with Outlook Express.
2. When I remove the certificate, I can again instantly connect and send
or receive mail (but I NEED the certificate for secure email exchange!,
so I can't just remove it forever!}. 3. The certificate actually works
for decryption - When I remove the cert, I can receive an encrypted
email, then I can re-import the cert and decrypt the email.

All of this leads me to believe that somehow Vista requires something
different with a digital cert than XP does, such that some security
feauture in Vista will not even connect to the server if there is
something it doesn't li ke, even though the cert seems to work fine for
decrypting. I don't understand why just having a certificate installed,
not even using signing or encryption, that Vista should not connect to
the server. I is very difficult to find any information on what Vista
might be doing with the certificate when attempting to connect to a mail
server.

Please help! Thanks.

I spent several hours going over all the documents at the link yo
provided, but none helped. thanks for providing that though.

I see that others are also having problems with digital certificate
installed and using Windows Mail or Live Mail. I cannot understan
whey the same certificate that works with Outlook Express on XP will no
work with Windows Mail on Vista, but there must be a reason. One othe
thing is that the certificate that won't work with Vista/Mail is fro
Thawte (but it does work with OE/XP), and the other certificates tha
work with both Vista/Mail and OE/XP are from other sources. I have n
idea if that has anything to do with the problem

Have you tried contacting Thawte or searching their website?

Perhaps this link will shed some light:
