  • Digital Signature using Outlook Web Access on Vista


    I have recently upgraded to Vista using Outlook 2007.

    I have installed my email digital signature onto my outlook 2007 client and this is working without any problems.

    The problem occurs when I try and use our OWA (Exchange 2003) on the vista machine. Each time I try and sign an email in OWA I get the following:

    "A digital ID that allows you to sign this message is missing. If you,r digital ID isn't trusted by the Exchange Server, you can't use it to sign messages. 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"

    I have installed S/MINE control but wonder if this is not compatiable with Vista as it seems to install but I don't get a installation complete message.

    Any help would be really appreciated.

    Is the server fully up to date on patches? OWA has had a number of updates for Vista support.
