[What and why:]<\/p>\n

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, or to selected text, and collaborate through replies and @mentions \u2015 bringing PDF review to parity with commenting in Office documents. This feature will be on by default and requires no admin action.<\/p>\n

[Rollout schedule:]<\/p>\n

General Availability (Worldwide, GCC, GCC High, DoD): We will begin rolling out mid-October 2026 and expect to complete by mid-November 2026.<\/p>\n

Note: This is a gradual rollout, so not all users will see the feature at the same time.<\/p>\n

[Impact on your organization:]<\/p>\n

Anchored comments appear in the Microsoft 365 file viewer when a PDF is opened in OneDrive or SharePoint on the web.<\/p>\n

Users will be able to:<\/p>\n

    \n
  • Comment anywhere \u2015 click a spot on a page to add a comment anchored to that location.<\/li>\n
  • Comment on text \u2015 select text and attach a comment to it.<\/li>\n
  • Collaborate \u2015 reply, @mention, see visual anchor indicators, and navigate between a comment and its anchored content; full keyboard and screen-reader support.<\/li>\n<\/ul>\n

    Who is affected: <\/p>\n

      \n
    • Users viewing PDFs in OneDrive and SharePoint on the web.<\/li>\n<\/ul>\n

      Default state: On by default for eligible users; no new anchored-comments-specific admin control is introduced.<\/p>\n

      Admin control: No new anchored-comments-specific control is introduced. Existing protections apply \u2015 sensitivity labels, Purview DLP, and Information Rights Management (IRM) on rights-managed libraries.<\/p>\n

      [Action required \/ Recommendations:]<\/p>\n

      No admin action is required before rollout. You may want to:<\/p>\n

      Inform your PDF users and helpdesk\/support teams about the new commenting experience.<\/p>\n

      Update internal collaboration guidance (commenting on a spot, text, or annotation; replies and @mentions; downloading with or without comments).<\/p>\n<\/td>\n<\/tr>\n
