I have a user who connects through terminal services (windows 2003) from a MAC. He uses outlook a lot and today his calendar shows his appointments as being 4 hours late, e.g. meeting at 7:30 AM is actually in the calendar for 11:30 AM. His blackberry (BES) shows the correct times. He is located in EST, his MAC shows EST and the time running along the left hand side shows EST.
I've dealt with this before but I don't remember what I did. I'm going to try the timezone fix tool but need to get a hold of him and I'm not sure if this will do anything.
