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.
