I am having an iPhone 4 with me and I am synchronizing notes, contacts and other details from my Microsoft Outlook. I am using Microsoft office 2003 on my computer which has Windows 7 as its operating system. For synchronizing my iPhone 4 with my details on Microsoft Outlook, I am using iTunes. Till now everything was fine and was properly synchronizing with my iPhone4 until I noticed that Microsoft Outlook’s calendar and its detail were not being synchronized. I again tried synchronizing, but again the synchronization of Microsoft Outlook calendar failed. I have tried various methods only to meet failure. No other problem in synchronization is noticed except for the one I mentioned. No error message or warning is given. Can someone tell me what the problem can be and how should I solve it?
