We’ve been running a preview of co-authoring on MIP-Encrypted/Information Protected documents.

As a follow up to the current ongoing preview, we have good news to share!

Co-authoring on MIP Encrypted Documents is now available in Current Channel builds of Office:

• Version 2105: June 18 Update or higher for Windows
• Version 16.50 or higher for Mac

While the feature is still in Preview, we are revising our guidance and customers are now welcome to deploy the feature on their production tenants.

Make sure to familiarize yourself with the metadata changes introduced as a part of the feature and ensure that all pre-requisites are met before enabling.
