If you're building a Prezi for someone else in your organization, it might be safer (for you and them) to export your design in a way that does not allow them to edit. There are two options that will allow you to share in this way. You can either share an online link or create a portable Prezi. The advantage of a portable Prezi is that all of its content is saved locally, and the presenter will not need an active Internet connection in order to present.
Tip
Remember, if you include embedded videos from a source such as YouTube or Vimeo, you'll need an active Internet connection for the presentation, no matter which method you choose.
The advantage of sharing a link to the online version of the Prezi is that it is a bit easier to use and requires much less file space, so it's easier to send.
