How to Share Your Office 2013 Files and Folders
Click the Share (or Share Folder) button or link.
You can find the Share button or link here, there, and everywhere: on the SkyDrive toolbar; in the Details pane; in an open Office file, by clicking the Share tab; or in an open Office file by clicking the File tab, choosing Share, and choosing Share with People in the Share window.
You see the dialog box for generating a link to your file or folder. (If you’re already sharing the file or folder, you see a list of people who share it with you. Click the Share With More People button.)
