What certificate are you using for your Exchange server?

I'm trying to gather some additional data to help address this problem. If you've had trouble syncing to the exchange server because you couldn't add root certs, can you please give me this information:

- Was this a self-signed certificate or was it purchased from an SSL vendor?

- If purchased, from which vendor?

- Did the CAB file method help you out? If not, what device do you have? I believe that method will work for most devices in the market, but I'm interested to know if any shipped in a configuration where that won't work and the operator/OEM haven't provided a solution.

Thanks for your input - my team has been working on solving this problem for future releases for quite some time now, but this information will help us further. I'll post the details about our work when the release becomes public information.
