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: 13/02/2026 08:43:00 AM –Microsoft’s metrics indicate that there are slow request response times, making the current metrics insufficient to proceed with re-enabling the “Edit in Outlook” button for the remaining 50 percent of users. They are reviewing possible options to improve request response times, so that they can bring the metrics up to an acceptable level before re-enabling the feature.

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.
