Issue/Introduction

You learned that scanning of Microsoft Teams content requires registering a Custom OAuth model application in the Azure account. All CloudSOC accounts with an active O365 Securlet must transition to the Custom OAuth method. Failure to transition by August 01, 2025 will result in the suspension of Teams content scanning. So you want to know if files shared in Teams also require the custom OAuth app.

Resolution

No, the files uploaded to Teams are covered by the Office 365 Securlet's OneDrive (Files uploaded to a direct message) and SharePoint (files uploaded to a Teams Channel).
