Any way to force sync between exchange and outlook


My user is having an issue with Outlook Calendar. Out environment is;
Exchange 2003
Office 2003

All of sudden, all appointments' time before noon on Calendar changed to 9 hours earlier than its original time. We are in Japan so for example, a meeting booked from 11:30am was changed to 2:30am...
However, when we check the Calendar from OWA on the internet browser, it's all correctly there. And the Calendar of an invitor has no problem.
I have deleted all files except .pst from a default Outlook folder, and unchecked Cache mode and everything but those were no help.

If someone can help me out here, please.
Thanks in advance.

did you check the time zone settings on the PC(s) in question and also the time zone settings on the server?

Thanks, yes I checked it both on the client and the server and there was no problem.
Funny thing is that not all appointments went wrong, only the appointments booked before noon.
Well, given that this has moved by 9 hours which is the same as the time zone offset for Japan from UTC then it is very likely time zone related. It's possible that those appointments got created in +0 time zone (as in UTC).

Microsoft has a tool for modifying timezone data in appointments, I'd give that a go:

The user just reported me that this started after he synchronizing his iPhone with the exchange server.
Do you feel it's still worth running that tool?
Ah, ok. Check the time zone settings on the iPhone. This may give you a clue, however, I have seen time zones on mobile devices being altered by the telco, where changed for a bit and then changed back, guessing someone stuffing around with settings in the mobile network.

If that does not give you any more clues then at the end of the day something (could be the iPhone) probably mangled the time zone settings in the appointments, and if that's so you need to fix them. That tool will hopefully let you do that.

Checked his iPhone and its timezone is set Tokyo.
So I ran the timezone tool, but it gave me a message that there is no appointment timezone to fix.
Maybe I should call it a day on this..
Hmm, well can't think of anything else, the fact that it's a 9 hour thing really suggest a timezone issue, and even if his iPhone is set correctly now, it may not have been at the time when the iPhone synced up.
So I still think it's probably going to be a timezone issue in the appointments, but it's possibly something even more obscure that the tool does not pick up on (which I guess the fact that OWA displays them correctly would possibly indicate).

Anyway, if it's just a one off incident, probably quicker to just fix the appointments affected, and just keep an eye out if it happens again, and if so, if it was triggered by an iPhone sync again.
