Hi,
I have a problem when trying to sign emails with an X.509 certificate in Outlook 2010. I constantly get the error message. The certificate is Verified for the email address I'm sending from.
"Invalid Certificate
Microsoft Outlook cannot sign or encrypt this message because you have no certificates which can be
used to send from your e-mail address."I have no problem with signing documents in Word 2010 with the same certificate, only when trying to send email.
Every check I can perform confirms that there's nothing wrong with the certificate. Yet, Outlook still says it is invalid.
I have even tried installing a second X.509 for the same email address just to check. Outlook doesn't seem to like either certificate.
I know this has been posted before, but I'm completely stuck here.
Thanks,
~Dan
