Microsoft is updating Office for the web to allow users to apply sensitivity labels with user-defined permissions (Viewer, Editor, Owner) directly in Word, Excel, and PowerPoint online, removing a previous limitation that required switching to desktop apps. The feature mirrors desktop behavior, requires proper licensing and label configuration in Purview/SharePoint/OneDrive, and currently lacks support for custom permission expiration in the web interface.
