I am receiving this error when I am trying to utilize OWA on my Windows 7 pc (64bit) & (32bit):
"A digital ID that allows you to sign this message is missing."
A digital id that allow you to sign this message is missing. If your digital ID isn’t trusted by the exchange server, you can’t use it to sign message. Ask your server administrator to have the issuer of the digital ID trusted, or send the message without a digital signature. If you have a smart card-based digital ID, insert the card and try to send the message again.
What should I do now? Please help me.
