copilot rewrite

The copilot rewrite tag covers Microsoft’s targeted Copilot drafting feature for Outlook on the web. In July 2026, the Co-Authoring Highlight and Rewrite feature is scheduled for General Availability for worldwide standard multi-tenant customers. It lets users highlight part of an email draft and ask Copilot to change the selected text’s length, tone, or structure. Coverage focuses on this specific in-browser workflow rather than broader claims about writing entire messages, managing mailboxes, or consistent availability across every Outlook client. Users remain responsible for reviewing the suggested wording before sending, making the feature relevant to practical email composition and controlled editing.
