Hi Adam,

Thanks for your post.

For the function of the SSL, you can refer to the following article:

What is TLS/SSL?

ef/ed5ae700-e05e-45ef-b536-45795dbb99a2.mspx

As for your question 2, from the Exchange 2003 viewpoint, the OMA/Server
ActiveSync features don't require certificates if you don't plan to enable
SSL for the HTTP connections for these mobile features. Also, in the mobile
devices with PocketPC 2003 or later as OS, you can choose either using
HTTPS or not using HTTPS when you try to use Exchange 2003 OMA/Server
ActiveSync features. If you choose using HTTPS, you may have to obtain a
certificate from an well-known third party CA or set up and issue your own
certificate by using the Windows 2003 CA service, and then implement the
certificate in your Exchange 2003 Server to enable SSL for OMA and Server
ActiveSync.

NOTE: If you plan to set up Windows 2003 CA Service and issue your own
certificate, it will not be trusted by your PPC mobile devices by default
and you may want to use the following tool on your PPC devices to disable
the SSL check:

Hope this clarifies. Should you have any questions or concerns, please
don't hesitate to let me know. It's my pleasure to assist.
