We are going through the DST changes here this weekend and it is a PAIN. We have over 600 Public Folders that we are having to update manually. BEWARE!!!!! If you use the tool built into MS Outlook 7, it will update all calendar items regardless of the date. Some of our calendars have over 6000 appointments and the tool in Outllok 7 tries to update them ALL. If you run the TZMove.msi file, it only updates the affected appointments, NOT ALL OF THEM!!!!! Of course Microsoft neglected to mention that in all of their documentation on this issue. Thanks Microsoft for another omission of critical information! Your the best! Terry Ball
