We're running Exchange 2003/SP1 on a single server that also hosts OWA, OMA. OWA & OMA work fine (OMA works in both SSL and non-SSL mode). EAS has never worked, and I recently went through the steps of re-initializing all the virtual directories hoping that would fix it. It didn't. Any user that attempts to sync receives the Support Code 0x85010004.
Any help is appreciated, this is driving me nuts.
