I've received a signed message from somebody. Outlook 2000 and 2003 won't let me open the message, I just get an error "Can't open this item. Your Digital ID name can not be found by the underlying security system.". The message is not encrypted and can be read by Outlook 2007. Other mails received in the past open fine and when I open the problem mails in Outlook 2007, the signature is verified (as I installed the certificate from the older mails - ie. it's the same signature). I don't understand why I need a Digital ID to read a mail that is signed by somebody else, and I should be able to see it (with a warning) without the certificate at all.
Does anybody know how to work around this issue? Googling didn't come up with anything, most people's problems in this area seem to be related to encryption. The sender is using Notes according to the headers. Any ideas?
