Outlook 2002 (XP) client cannot open Digitalally Signed Emails - HOT
Posted on 2006-07-10
I have one user on my network who is unable to open ANY email that has been digitally signed (not encrypted). He is using Outlook 2002 SP3 via an Exchange connection. If he opens up his mailbox through Outlook Web Access, he CAN indeed open the digitally signed email and read the contents of the message. When he attempts to open the email in his Outlook client, he does get an error which is:
"Microsoft Outlook could not sign or encrypt this message because you have no certificates which can be used to send from the email address "firstname.lastname@example.org"- generic, not his real email address, durr.
This error comes up when he attempts to OPEN the email. His OS is Windows XP SP2.
Any ideas? I succesfully opened this email from my machine which is Outlook 2003 (and I do not have a DCert) and from another client which is running the same version of Outlook- and it opened with no problem. I also cleared his SSL State.
