I should've known it was too good to be true. All of my organisation's Outlook calendar appointments between 27 August 2001 and 29 October 2001 are now one hour out. This is because of last year's daylight savings timezone change, and the patch that was run in March this year removed the Year 2000 only time zone, but something is still screwed up. Recurring appointments over a 12 month period show correct time everywhere except during this 2 month period, where if you click on it it shows 11pm - 11pm. Any ideas or suggestions on how to do anything else EXCEPT manually move all appointments would be appreciated.
