Locked shapes, objects, images or tables in your PowerPoint presentation can be unlocked using PPT Productivity.

Select the PowerPoint slide/s containing locked shape(s) you need to unlock, then click 'Unlock objects' (Found beneath the Lock Object icon on the PPT Productivity Ribbon).

The file will close momentarily and reopen (you need to first save your document to a local drive). Previously locked objects will then be unlocked and can be moved and edited like any other shape or image.
