I've recently setup a new RPC over HTTPS solution for a client. Users are attaching to a hosted Exchange 2003 Server in our data center from a remote site. Works great, set it up with few issues thanks to the help received on this site.
An unexpected turn this past couple days was that the client had several workstations that are Windows 2000, where Outlook clients can't use RPC over HTTPS (if there is a way, please let me know).
For those users, I created a connection to the new Exchange Server via IMAP - which to me isn't ideal, but at least they could access mail. Now these users are looking for an address book - (GAL) which of course isn't available.
Does anyone know of a way to solve this, short of an upgrade? :)
