No need to import unless you want old stuff. U can setup your phone to get email and leave it on the server for your outlook to get later. I used to have it setup to delete off my host server once I delete it at my PC through outlook. I now just forward my mail to my gmail because I like the opush feature and see my mail sooner which for me is nice. My PC is like an archiver now. So I don't have to worry if I accidently delete one on my phone. It depends on your over al goals of how you want to use outlook or if you want to migrate yourself to using your phone for the greater part of emailing. I have done the latter.
