Description

This policy controls whether Word can use lock‑free coauthoring in collaboration sessions. Lock‑free coauthoring allows multiple collaborators to edit the same paragraph at the same time when supported for a collaboration session. If you enable this policy, Word will not use lock‑free coauthoring and will instead use the existing coauthoring behavior to support collaboration across the session. If you disable or do not configure this policy, Word will automatically use lock‑free coauthoring when it is supported for a collaboration session.
