Look at your contacts in Outlook 2010 and you’ll spot a new contacts folder called Suggested Contacts. This is a list of everyone
you've emailed and everyone who has mailed you who isn’t already in your contacts folder. So when you’re typing a name into a new message, Outlook will look in here to see if it can find the email address for you. You can also drag addresses from here into the main Contacts folder if you want. This is much less intrusive than asking if you want to save every new email sender as a contact and should save a lot of searching through your inbox to dig out addresses manually. But be careful about capitalization. Outlook now treats peter@ and Peter@ as different contacts.
