All-day events in Entourage one day behind OWA Exchange Server

[JHoffy]

Let me preface this by the fact that all of my time zones are set to Eastern on Outlook Web Access, my PCs, my Macs, and my iphone.

When I input an All-day event into my exchange server OWA, it shws up on my PCs in Outlook as the correct day, however on my Macs it shows up one day prior in Entourage. So, when I sync my iphone it also shows up one day proir. This does not happen if I input a timed even.

Please Help!
