Distribution lists are called “Contact Groups” in Outlook 2013. You are not able to export and import contact groups in the same way that you do address books; however, you may forward them to others (PC to PC only) as an email attachment. Follow these steps to e-mail your contact groups to another person.
1. Open your contact group from within your Outlook contacts/people. Click on the “Forward Group” button, and choose “As an Outlook Contact”.
2. Outlook creates an e-mail message and turns the contact group into an attachment. Address the e-mail message as you normally do, type your message, and click Send
