Show contact name that save in outlook app as Caller ID?
I don't think the iPhone can use the contacts in Outlook app.
However you can syncrhonize your contacts through iTunes : 


Connect your iPhone or iPod touch to your computer using the cable provided with your device or by placing the iPhone or iPod touch in the Apple Universal Dock
iTunes opens automatically when connected to your computer.
In iTunes, in the source list, under Devices, click the entry for your iPhone or iPod touch.
Click the Info tab.
Under Contacts, click Sync contacts from, and then click Outlook.


Or you can try to add your contacts in your iPhone :

Settings -> Mails Contacts, Calendar -> Add an account

And then just syncrhonize your contacts.
