Microsoft Whiteboard provides a freeform intelligent canvas where teams can ideate, create, and collaborate visually via the cloud. Designed for pen and touch, it lets you write or draw as smoothly as you would with ink, while automatically recognizing and transforming shapes and tables as you draw. It enhances teamwork by allowing all team members to edit and comment directly on the canvas in real time, no matter where they are. And all your work stays safe in the cloud, ready to be picked back up from another location or device.

Lot's of new Whiteboard goodness in this release. Smash that UPDATE button to:
  • Lock any image to the whiteboard background and never worry about accidentally erasing, moving or having to recreate template-like content again.
  • Make sure your whiteboard is easy for people of all abilities to read and edit with a new Accessibility Checker.
  • Access improved sticky note editing experience. Just double tap to add text & let your ideas flow fast.
  • Your recognized shapes and tables now have a hand-drawn effect applied to them to help you impress your peers with your penmanship.
  • When opening a whiteboard, we now show you a fancy loading animation to help pass the time (and so you don't sit wondering if anything is happening).
  • A sprinkling of usability, performance and bug fixes to make your whiteboarding experience a bit more polished.
