Hi there

We're trialling a Windows Mobile 5 based PDA - we're working on trying to get it to synchronise with an Exchange 2003 server - but my collegues are telling me that we have to buy a commercial certificate to get synchronisation working with Windows Mobile 5.

We've had no luck using a certificate issued from our own CA that we've installed on Windows Server - doesn't seem to work in the same way as Pocket PC 2003.

Is this true?  Do I really need to buy a commercial Certificate to make this work?  If not, can someone point me to some information to get my own certificate issued by a Windows 2003 based certificate services to work right.

No, you don't need a commercial cert, but you DO need to have access to be able to load additional certs if you aren't going to use a commercial cert.

There are some devices that are totally locked down by the provider.  If you don't want to use a commercial cert (I don't blame you for not using one just for a trial), then check with the vendor and see if they will allow you to install a 3rd party (or self-signed cert).

I've blogged about this a few times.

the second one references a blog from another friend about the same subject.

I've got synchronization working on mine using a wildcard cert (totally unsupported), but I know several people who are using self-signed.  It's all about what the provider will support on their customized version of the device.
