Restore computer without deleting emails.

[[TC]►Leon◄]

Hey guys.

My dad has a Dell Latitude E6400 laptop that he uses for work at home and it is slow beyond belief. Absolutely everything takes ages to load up and more often than not, it freezes during Windows startup. Being the technical genius that I am (This is sarcasm for those that hadn´t noticed) I´m going to a system restore. I should be able to figure that out since I´ve done it on my own laptops a few times in the past. I´ve managed to pull most of the files out of his computer and the issue at hand is all of his e-mails. They can and must not be deleted. How do I pull these emails off the computer so that they can be put back in place afterwards or back them up? He uses Outlook on Windows XP.

P.S: My dad works for himself, so there´s no tech support.

TL: DR: WinXP computer needs a restore. How do I backup the email?
