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: When users prompt Copilot Chat to draft an email message, the button to “Edit in Outlook” may not appear as expected.

Current Update: 06/02/2026 08:43:00 AM – After re-enabling the feature for 50 percent of the affected environment and then pausing the rollout, the current metrics Microsoft has reviewed are not substantial enough to confirm whether to proceed with re-enabling for the remaining 50 percent. They are continuing to monitor metrics until our next scheduled communication update to gather more insight and determine when to proceed with further enabling.

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

Root cause: Microsoft has disabled the “Edit in Outlook” feature in Copilot Chat while they implement a fix for a separate service issue relating to the feature, causing impact.
