When you try to insert a picture from your camera for the first time, OneNote will ask for your permission to use it. If you decline and try inserting a picture again later, you may see the error message, “This app needs permissions to use your camera. You can change this in the app’s settings.”

• SWIPE in from the RIGHT side of the SCREEN and on the BAR that appears, choose Settings (if you're using a mouse, move it to the upper-right corner to reveal the bar).
• At the bottom of the Settings pane that appears, choose PC Settings.
• On the PC Settings screen, click or tap PRIVACY.
• On the Privacy screen, click or tap Webcam.
• Make sure webcam permissions are set to on and then turn the OneNote permissions to on.
