Hi I have a problem with the Outlook 2007 calendar. In 2003 calendar there wasn't any problem. But in 2007 the behind code time: DTSTART:20100907T070000Z DTEND:20100907T090000Z But it seems in calendar interface: Start Time: 08:00 End Time: 10:00 I checked the time zone settings of my outlook. There is no problem. Can anyone help me with this? Thanks
