So our daylight savings transition has gone no better or worse than expected. As explained before, we followed all the Microsoft instructions, yet their timezone move tool only correctly handled about half of the incorrect calendar entries. The only solution left is to manually open each item and re-save it. Although tedious, at least this finally resolves the problem. Have you found a way to do this on a global scale?
Oh, and the Blackberry DST update blew up partway through, and I had to reinstall all my handheld software. We have lost a lot of time on this daylight savings time change!
