When you’re done using the whiteboard, be sure to email the whiteboard file to yourself (and the other people in the session if you want) so you’ll have it later.
When you’re done with your session, the Surface Hub will be reset for the next person—your files won’t be available anymore and you won't be able to recover them. That's why it's important to email the whiteboard files to yourself.
Select the Email button at the bottom of the whiteboard.
On the Share pane, select Email.
Your files will be automatically attached to the email message, and the meeting organizer's email address will be in the To: field. Add anyone else you want, and then select Send.
