Question

Your organization applies sensitivity labels with encryption to Word, Excel, and PowerPoint files stored in SharePoint Online. Users report that when two people open the same labeled and encrypted document at the same time, they cannot see each other's changes in real time and AutoSave is disabled. You need to enable real-time collaboration on these encrypted files while retaining the existing encryption. What should you do first?

Accepted Answer

Enable the tenant setting to support co-authoring for files with sensitivity labels in the Microsoft Purview portal.

Answer

Remove encryption from the sensitivity labels and rely on SharePoint permissions instead.

Answer

Configure the labels to use Double Key Encryption so that both users share the same key.

Answer

Republish the labels with the 'Let users assign permissions when they apply the label' option enabled.
