I have an Administrator who's having a calendar issue with her Outlook 2003. She has two assistants who share her calendar, one is using Outlook 2007 and the other 2003. Well recently the appointment times are all off by an hour. I found out that this has nothing to do with DST because apparently the time has been off for some months. i.e. the Administrator will have an appointment for 1pm and it shows 2pm. After looking at the Admin client we found that her time zone was set incorrectly...however this didn't resolve the problem. For new appointments YES, the time is correct on all calendars however, the re-occuring appointemnts which were set months ago will not update to the new time zone settings. Any ideas??
