I currently have a dilemma that's got me in a rut at the moment. I need clients to be able to use Outlook XP to access my E2007 Server. I know that RPC over HTTP is only available for clients from 2003+. Is there any way that I can get RPC over HTTP to work with my Outlook XP clients to access the Exchange Server (maybe a workarond that MS doesn't support at the moment)? I would use IMAP, but I've learned that it doesn't support public folders in E2007. I really need public folder access, and don't have the current funds to setup SharePoint Services. Am I SOL? Any help would be appreciated.
