It's easy. Add Windows Live friends to your contact list by clicking the “Add Contact” button – the same way you’ve always added friends to your contact list. To start IMing, your Windows Live friend must accept your invitation. Also, they must be using the latest version of Windows Live™ Messenger. If your IM detects a need for them to upgrade, your invitation will automatically include a link for them to download the Windows Live™ Messenger.

Once you’re both running the latest versions and you’re both on each other’s contact lists, it’s time to get down to business. Let the instant messaging begin!
