We noticed this problem with recurring appointments that were created prior to the 2007 changes to daylight savings time. We resolved the issue by deleting the recurring appointment and re-creating it. When you delete it, you have to select delete the entire series rather than delete one occurrence. After re-creating the recurring appointment, you should notice that the time is correct this week and the time will still be correct after the time change on March 8th. I know it is more of a work-around than a fix, but it is the only thing that worked for us. Hope this helps.

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
