Outlook Copilot themes are going away

Microsoft is retiring Themes by Copilot in Outlook worldwide, with removal scheduled to begin in mid-October 2026 and finish by late October. Existing themes will remain until users switch to another theme, but they won’t be able to select or restore a Copilot theme afterward.
