 In Microsoft 365 organizations that have Microsoft Defender for Office 365 Plan 2 (add-on licenses or included in subscriptions like Microsoft 365 E5), user reported Teams messages are available on the **User reported** tab of the **Submissions** page. It's easy to find them if you filter the results by the **Message type** value **Teams message**.
 
 If you select a Teams message entry on the **User reported** tab by clicking anywhere in the row other than the check box next to the first column, a details flyout opens.
