One of our GM's has a problem in that when he sends a meeting request it is entered into the recipients calender and hour early. I.E. if I put in a meeting requestfor 1400 on the blackberry it will appear in the recipients calender for 1300. I am in Perth (GMT+8) and have checked all the date and time settings, daylight savings, etc etc to no avail. Any help would be greatly appreciated.

This is going to sound silly, and it's only a work around until you sort it out properly, but why not ask him to send out meeting requests an hour later than he wants? At least that way the recipients will get the right time - all he has to do is remember he's working an hour ahead.

is the problem with the time being wrong on only on person's blackberry or on multiple users?
