Prevent co-authoring

This policy setting controls how PowerPoint opens a file for editing on document management servers that support co-authoring. If you enable this policy setting, PowerPoint will prevent co-authoring by taking an exclusive file lock. If you disable or do not configure this policy setting, PowerPoint will allow co-authoring by taking short-term shared locks. Note: When file synchronization via SOAP over HTTP is turned off it will prevent co-authoring.
