You can add services like Facebook for Office, Flickr, or YouTube so you can quickly add images, videos, or files to an Office file by clicking File > Account > Add a service.
You can also add services for storing your files, like SkyDrive or SharePoint, or for sharing your files, like Facebook, LinkedIn, or Twitter.
If you can’t choose or see a service, you might need to sign in to Office. Or you might see different services if you are signed in under a Personal or Organization account.
