I'm also looking for a fix as I have the same or a similar problem. I also
have some information that may be the same as other people that have this
problem.
1) adding a certificate using certmgr works just fine and the certificate is
visible from certmgr afterwards
2) the accounts::security tab in Windows Mail can see the certificate
3) The certificate does NOT show up in the Personal tab of
"Options::Security:
igital IDs... from Windows Mail
4) The certificate also does NOT show up in the Internet
Options::Content::Certifcates tool in IE7
5) adding a certificate from IE7 or Windows Mail does not help the situation
In some regards it seems that IE7 and parts of Windows Mail are looking in
the wrong place for the certificate, but I can't figure out how to tell them
what the right place is.
