Provisioning a Teams Chat Service Account


Microsoft is going to require the following licenses for Teams Chat message subscription:

  • Office 365 E5

  • Office 365 A5

  • Microsoft 365 E5

  • Microsoft 365 A5

  • Microsoft 365 Information Protection and Governance

  • Office 365 Advanced Compliance

To make sure Cloud App Security can continue protecting your Teams Chat messages after this requirement is applied, Trend Micro recommends you use one of the preceding licenses to provision your Teams Chat service account. For more information, see the Microsoft documentation.

Provision a service account for Microsoft Teams (Chat) to allow Cloud App Security to run advanced threat protection and data loss prevention scanning on messages and files in protected private chats.


Cloud App Security protects the Teams and Chat services in Microsoft Teams separately.

Cloud App Security scans contents and files that employees send within private chats with other users (one to one or one to many). Private chat files are stored in the sender's OneDrive folder.

If you have also provisioned a OneDrive service account, when the user sending or uploading a file is selected as a policy target respectively, Cloud App Security applies the corresponding policies for Teams Chat and for OneDrive to this file.

The steps outlined below detail how to provision a service account for Teams Chat from Dashboard.

  1. Log on to the Cloud App Security management console.
  2. Hover over Teams Chat and click Provision.

    The Provision Service Account for Teams Chat screen appears.

  3. Click Click here at the end of Step 1.

    The Microsoft logon screen appears.

  4. Specify your Office 365 Global Administrator credentials and click Sign in.

    The Microsoft authorization screen appears.

  5. Click Accept to grant Cloud App Security permission to use the Graph API to access your Teams Chat related service data.
  6. Go back to the Cloud App Security management console and click Done.

    Cloud App Security then updates the Teams Chat data in your organization. The time required depends on how much data you have in Teams Chat.

  7. Hover over the ring icon in the upper-right corner of the management console.

    If the message "Teams Chat protected." appears on the Notifications screen, the provisioning is successful.
