OneDrive: Anchored comments in the PDF viewer

Microsoft 365 Message Center Archive by Merill Fernando

Summary

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.
