How can I reset a MacBook Pro?

Episode 1438 (2:08:26)

DJ from Duluth, GA
MacBook Pro

DJ is trying to help a friend out who wants to reset her MacBook, but he's worried that she won't be able to use her Microsoft Office software because she doesn't have the key anymore. Leo says that there's a system reset that won't break the connections of the software. So it could pay to try that first. If that doesn't work and they have to erase the hard drive, they could get the key from Microsoft again. It'll take a simple call.

How does he copy the calendar, contacts, and email from Outlook on a Mac? Leo says using the archiving feature would work. It creates a .OLM file. He can copy them and then restore them.
