NHSmail Reference: INC46533087

Microsoft Reference: CP918548

Issue Status: RESOLVED

Issue Description: Users without proper licenses are able to see the Microsoft Copilot (Microsoft 365) app button within Microsoft Teams.

More info: This was a rare and intermittent issue. Affected users without Copilot licenses were not able to access Copilot in Teams, despite the UI button being present due to the issue. If an affected user attempted to click on the Copilot app button within Microsoft Teams, it failed and they were subsequently unable to navigate to other areas of Microsoft Teams, such as chats, calendar, and more. Users who entered this scenario could restart their Microsoft Teams session to mitigate the issue.

Final Update: 04/11/2024 08:58:00 AM – Microsoft have confirmed the deployment of the fix has reached 100 percent of affected environments and all customers will see remediation with Teams version 24100324914.

Scope of impact: This issue may have impacted users without Copilot licenses that updated their settings or preferences in Microsoft Teams mobile or web apps and then subsequently clicked the Copilot app button.

Root cause: When users update their settings or preferences in Microsoft Teams mobile or web apps, the settings change populated across to the Microsoft Teams desktop client as well, resulting in the Copilot app button appearing due to the code for settings and preferences updates not including a license check.

Next steps: Microsoft are further reviewing how the impact scenario was introduced to identify opportunities to prevent similar issues in the future.

Microsoft will provide a preliminary Post-Incident Report within two business days and a final Post-Incident Report within five business days.
