Sync Issues

If I make a change to my contacts on my iPad and sync it with Outlook, the change will pull what Outlook has back to my iPad and undo that change. I want the change I make on my iPad to change on Outlook as well.

How do I do this?

Thanks

 

Anyone? This shouldn't be hard, but I can't figure it out. I just want outlook and the iPad to keep the newest change when they sync. Is this possible?
