Using Outlook's NetFolder feature, another user sent a invitation to join a calendar and after I have approved the calendar and the calendar entries start coming in they are showing up an hour earlier than they are suppost to (one entry shows a meeting at 10 which is suppost to be showing at 11:00).

Any ideas?

Do you have' Dalight Savings Time 'or where the messages originate .
Just a guess.

This is outlook's gayness at it's best- Outlook and windows when panicking will sometimes set your timezone to Pacific for no good reason other than to irritate you. On occasoin, it even does something stupid like the daylight savings time or a different time zone. Again, just to make you mad enough to do a George Carlin impression.

Go into your time, set your timezone as appropriate, and be sure to set the time as appropriate if needed. Then tell it to apply, restart outlook and be happy as the time has restored itself. 90% of the time I"ve seen outlook do this, either your machine or the client machine have an improperly set timezone.

Hope this helps. If it doesn't, can you perhaps post a meeting invitation's header here?
