Issue Status : RESOLVED

Issue Description : Some users may not see all Microsoft Teams meeting details on Microsoft Managed Desktop (MMD) devices.

More info : This problem only occurs in organizations where AppLocker is enabled. Impact is specific to users reviewing Microsoft Teams meeting information who have enabled the “Try the new Teams” option in Microsoft Teams. The problem occurs in both the Microsoft Teams meeting item and in the Outlook calendar event connected to the meeting.

Users can directly disable the “Try the new Teams” toggle to avoid this issue further.

Admins can disable the option in Microsoft Teams for MMD users to install the new Teams experience. The following link contains instructions for how admins can disable the “Try the new Teams” toggle: https://techcommunity.microsoft.com/t5/microsoft-teams-blog/enable-the-new-microsoft-teams-toggle-for-your-organization/ba-p/3781345

Final Update : 07/09/2023 11:17:00 AM – Microsoft received confirmation from the affected users that the issue is resolved and impact is no longer occurring.

Scope of impact : Any user may be impacted if they enable the “Try the new Teams” option on Microsoft Teams and AppLocker is enabled in their organization’s environment; however, only a small number of users are currently impacted.

Root cause : A code issue within the AppLocker function that the new Microsoft Teams Meeting Add-In uses is causing the meeting to not generate the Teams meeting information correctly, resulting in impact.

Next steps : Microsoft are reviewing their coding procedures to better identify similar issues during their development and testing cycles.
