we have a 2003 SBS server with Exchange 2003 SP2. My boss using Outlook 2007 on her computer. she has noticed that in OWA, several of her calendar items are missing, but they all appear properly in Outlook 2007. someone suggested to me that it might only be the recurring events that dont show up but we just looked at that and while the ones not showing up are indeed recurring, there are plenty of others that are also recurring that do show up. I google searched this and found results for the opposite issue (i.e. calendar events in owa not appearing in outlook 2007) but I didn't see anything that fit this issue.
