iPhone4 – Outlook 2007 Sync

Hello everyone,

I need your help for solving a problem with syncing Calendar between Outlok 2007 and iPhone4 thru iTunes.
I am using a win7 laptop for this purpose but am unable to sync because the sync in progress is stuck waiting for the com.apple.outlook.clien.exe which crashed every time I try.
As for the contacts sync I can do that with syncing to Google contacts thru the same iTunes (ver.10)
The problem is iTunes do not offer the choice for calendar other than Outlook.
Is there a solution for this problem?
Thank you for your help.
