Exactly the same problem here.
iPhone running iOS 6.1.3 randomly chooses to not sync certain calendar entries from Exchange Server 2007.
Bizarrely - iPad running iOS 6.1.3 works perfectly fine.
I've tried loads of things.
Exchange Server is up to date.
We've had this issue for years now...and still no fix from Apple.
It basically makes the iPhone unreliable with anything calendar related.
