Check to see if the appointment is in OWA - if it is - is should sync to the phone. &nbsp;If it is in OWA and the phone has not picked up the change - remove the Exchange account from the phone and set it up again.<br />
<br />
If it is not in OWA - then delete the account from Outlook and set that up again.<br />
<br />
What Anti-Virus software is installed on the Exchange Server?<br />

Have you installed the latest service pack on your CAS and Mailbox servers? &nbsp;Are your CDO.DLL and MAPI files at the same build levels?

Hi alanhardisty<br />
<br />
The appointment show on OWA but I can't confirm it was show on 7/7/2011 or since the VVIP only realize that the appoitment on 8/7/2011 on his IPHONE. How can I check if the appointment show on his OWA on same date from server ends, like event viewer and etc? Let say that if his phone not pick up the changes on time, what is cause?where can I get the proof to show to him?<br />

Hi Delphineous<br />
<br />
How do I check the version?
</div>


<div>
Unless you already have your logging turned to Maximum; there is no log of a person performing any action within their own mailbox. &nbsp;By the way - you should only turn logging on to Maximum for the different features while troubleshooting an issue - it should not be left on full time as it will impact performance and consume mass amounts of disk space.<br />
<br />
The server versions can be verified by checking in Exchange Management Console.
</div>


<div>
You need to get hold of your VVIP's iPhone and sit down and test with OWA and the iPhone so that you can see where the problem lies.<br />
<br />
What is visible in OWA, should be visible on the iPhone - exactly the same as in OWA.<br />
<br />
If there are issues - there may be Anti-Virus interference. &nbsp;What do you have installed?

I have a VVIP said that his IPHONE sync with Outlook calendar not uptodate. His PA had modified his calendar on 7/7/2011 at 5.30pm. However, he said that the modified calendar only sync to his IPHONE on 8/7/2011.<br />
<br />
When I run Get-ActiveSyncDeviceStatis<wbr />tics -Mailbox VVIP, it show no records sync on 7/7/2011 but there is sync activity on 8/7/2011. Check on eventviewer on CAS server also not found anything error related to this VVIP.<br />
<br />
My Question are:<br />
<br />
1. How do we check when the sync from his PA calendar to Exchange occur?<br />
2. How to check the sync activity on 7/7/2011
