I made a mistake trying to get IMF running ... we have a w2k3 server
running Exchange 2003 SP2.
I installed the V1 over the existing V2 that's part of SP2 for Exchange. When I realized that I had downloaded and followed the V1 Deployment Guide. Uninstalled the V1, and V2 went with it.
I think I need to reapply Exchange SP2 to get it back.
