Before ending your session, be sure to email or save any files you want to keep—when you end a meeting those files are removed to help protect your privacy, and you won't be able to get them back. For more info, see Save or send your files.
When you're ready, select End session at the bottom of the Surface Hub touchscreen.
You’ll have the chance to cancel and go back and save or email files before everything is cleared from the Surface Hub.
