In Word 2013, you can now present your document live online to colleagues, even if they don’t have Office 2013 installed. The Present Online feature gives you the choice of using Microsoft Lync 2013 or the free Office Presentation Service to connect to others. This way, you can walk them through a review of your document. You can also share meeting notes you’ve prepared in Microsoft OneNote 2013, and participants will be able to download a copy of your document, if they choose.
Open the document that you want to use in your presentation and click the File tab to display Backstage view.
Click Present Online.
