Importing Certificates to Windows Mobile 6 devices

Hi,

We are trying to generate certificates for Windows Mobile 6 devices.

They tell me that the Certificate Manager application on these devices

will not import .cer and .pvk file. It is looking for a .pfx file. I

have been unable to export the certificates in this format.

When I try to use the Certificate Export WIzard from the CA the option

to export to a PKCS #12 format is greyed out. I've also tried to do a

certutil -getkey using the certificate's serial number but it comes

back with "cannot find object or property" . The certificate template

does have the box "Allow private key to be exported" checked.

Thanks.
