Adding to Exchange Calendar

[jskolm85]

How do I add an event to my Exchange 2003 calendar from my phone? When I create a new event and select which calendar I want to add it to I have 3 options, My Calendar, PC Sync, and Gmail. I don't have the option to select my Exchange account. All my events that are created on the computer in Outlook do sync to my phone though. I have checked that the calendar is checked in the account settings.

Any ideas?
