We start to see this every time that daylight savings time comes around. It makes sense when you think it through since repeat scheduled events that span a daylight saving transition do need something to happen to them. If the change occurred at the actual daylight saving transition then it wouldn't be a problem but the timing is off. -----Original Message----- From: MSU Network Administrators Group [mailto:[log in to unmask]] On Behalf Of Oscar Castaneda Sent: Tuesday, March 03, 2009 11:35 AM To: [log in to unmask] Subject: [MSUNAG] exchange calendar MSUNAGers, I run Exchange 2003. I just noticed (not sure when it changed) that a couple of periodical events in the calendar (say, staff meeting every Monday at 10AM) where changed one hour, from 10AM to 11AM. At this point I am not really sure if it was a user input mistake or a Exchange issue. Given the fact that Day Saving Time is about to kick in, I am a little puzzled about this problem. Did anybody had this kind of problem? -- Oscar Castaneda Michigan State University
