Problems sync. calendar with owa calendar, ipad calendar & iphone calendar

Hi guys, Hope you can help me out!
I have a user, actually the President of the company who is having issues with his calendar synching up primarly with OWA, then with ipad, iphone.

So, when he puts his 11:00AM for the next day, he won't see it on owa, then he is missing his 10:30 & 11:00AM appoitnments in iphone & ipad.

Please help, very critical to get this resolve today!

What version of Exchange are you using?
When he is entering his appointments - what device is he using?  PC with Outlook, OWA, iPad or the iPhone.
If Outlook - sounds like his Offline file is not syncing properly - just delete it and re-create it (close Outlook first - then delete the .OST file - then open up Outlook and wait for the file to be regerated completely).

Exchange 2003.

He is using his PC with outlook.

If outlook > that will make synchronizing to all of those devices?? (owa, ipad, iphone)

I didn't work!

An example from the future – calendar for tomorrow: 11/11
Outlook application calendar has all meetings
OWA is missing 9:30 am meeting (a recurring meeting that was changed for this instance)
iPad/iPhone is missing 9:30 am meeting (a recurring meeting that was changed for this instance) and 4:30 pm meeting (that was tentatively accepted)

In that case - plan B is to dismount the mailstore and repair it!
You need to run:
eseutil /p
eseutil /d
isinteg -s servername -fix -tests alltests
If you are not familiar with how to do this, please let me know and I will give you more specific steps.
isinteg needs to be run as many times as it takes to see 0 errors and 0 fixes in the last output line on the screen.
eseutil takes about 1 hour to process 4-6 Gb of mailstore, so the larer the mailstore - the longer it will be offline!
