I, as have many others, have been struggling with ActiveSync working in conjunction with Microsoft TMG and Exchange 2003. I have OWA working great to the Internet, but ActiveSync fails with this error (provided by AccessMyLan ActiveSync Tester: ActiveSync detected, but access denied. [HTTP 403: Disabled for this user].)

I have checked and rechecked virtual directory permissions ad nauseum, and from what I have read, recreating them is generally not helpful and a long and tedious process. I'm SOOOO close--what else can I try?
