Issue Status: RESOLVED

Issue Description: Users intermittently can’t access Microsoft Copilot (Microsoft 365) in Microsoft Teams and receive a “Coming Soon” page.

Final Update: 05/09/2025 08:45:00 AM – Microsoft have monitored their service health telemetry to confirm that their fix has fully deployed and saturated within the affected environment, and impact is now remediated.

Scope of impact: Any user attempting to access Copilot in Microsoft Teams may be intermittently impacted.

Root cause: A recent update meant to improve service efficiency prevented call requests from fetching the eligibility status of Copilot in Microsoft Teams while in a cached state when users attempted to access it, resulting in impact.

Next steps: Microsoft are reviewing their internal testing and validation processes to help understand how this was missed and to drive further improvements to help prevent similar issues from occurring in the future.
