Customer of mine is using SBS 2008 64bits with Exchange 2007 running on it. A calendar is being share between a primary user and 2 other assistant with editor permission. They have been experiening calendar not syncing among these 3 people. In order to get the latest calendar for the 2 users, sometimes they have to uncheck and recheck the calendar display in their outlook for the primary user to get the updated calendar. Currently, I have unchecked cache mode for all of them in outlook and it is syncing a little better. But, it stills show intermittent result. Here is a few more details I know.
Primary user - using Outlook 2010 on winows 7
2nd user - using Outlook 2007 on windows 7
3rd user - using Outlook 2003 on windows XP
DNS is running from the firewall not on the SBS. Wonder if this is a major issue giving SBS utilize DNS service to register and keep track of all the pc on the network.
I hope someone can give me some pointers on how the calendar share works and a fix for this problem
