Feature overview

Microsoft is adding anchored comments to the PDF viewer in OneDrive and SharePoint on the web. Users can attach a comment to a specific spot on a page, to selected text, and collaborate through replies and @mentions — bringing PDF review to parity with commenting in Office documents. This feature will be on by default and requires no admin action.
