Issue Status: ONGOING

Issue Description: Users aren’t shown the “Edit in Outlook” button after prompting Copilot Chat to draft an email message

More info: As an optional work around, affected users can use the Copy button to transfer a generated draft from Copilot Chat to Outlook, and continue their work. If your organization has enabled Copilot access within Outlook, the user can continue using Copilot to draft an email once they’ve moved to Outlook.

Current Update: 31/03/2026 08:42:00 AM : Microsoft are continuing their evaluation regarding whether further latency is expected to occur before we proceed with the re-enablement for the feature to all affected users. They will provide a timeline for remediation as soon as one becomes available.

Scope of impact: Any user prompting Copilot Chat to draft an email message may be impacted.

Root cause: As part of our ongoing efforts to strengthen the Copilot platform, the “Edit in Outlook” feature is temporarily disabled while we address an upstream code issue affecting that feature. Affected users are encouraged to review the workaround information in the more info above while we continue to prepare a comprehensive solution.
