I've got a machine here with DST issues. All calendar appointments in OWA are at the correct times, but on the local machine they're an hour ahead when the time is set correctly with the "Auto correct for DST" option enabled.

Annoyingly, Outlook tries to be "helpful" and moves appointments when the DST option is changed as it treats it as a change of timezone.

I can use the Microsoft Time Zone mode utility but it only moves appointments created by the user, anything that someone else has created remains as the wrong time.

Everything was fine until this weekend, the DST change has mucked it up and I can see why. Only this one person seems to be effected.

Any ideas?
