Important
Important
Cloud Email and Collaboration Protection protects the Teams and Chat services in Microsoft Teams separately.
Cloud Email and Collaboration Protection scans files that employees share in team channels, which are stored in SharePoint.
If you have also granted Cloud Email and Collaboration Protection access to SharePoint Online, when the SharePoint site and the team corresponding to a file are selected as a policy target respectively, Cloud Email and Collaboration Protection applies policies for Microsoft Teams (Teams) to this site unless the site does not hit any policy for Microsoft Teams.
The steps outlined below detail how to grant access to Microsoft Teams (Teams) from Dashboard.

Procedure

  1. Go to Dashboard → Service Status.
  2. Click Grant Access in the Action column for Microsoft Teams.
    The Grant Access to Microsoft Teams screen appears.
  3. Select the policy to enable automatically when the access grant is complete.
  4. Click Grant Permission.
  5. Specify your Office 365 Global Administrator credentials and click Sign in.
    The Microsoft authorization screen appears.
  6. Click Accept to grant Cloud Email and Collaboration Protection permissions on teams in your organization.
  7. Go back to the Cloud Email and Collaboration Protection management console as instructed.
    Cloud Email and Collaboration Protection assigned an App Id for Microsoft Teams that will be used for permission request on the SharePoint admin center in the next step. Copy the App Id from the screen and paste it in step 4 as instructed.
    If you decide to perform step 8 later, you can find the App Id under the corresponding Authorized Account from Administration → Service Account.
  8. Perform the following steps to grant Cloud Email and Collaboration Protection permissions to receive notifications from Microsoft upon any change to the files in your teams.
    1. Log on to the Microsoft 365 admin center with your Global Administrator account.
    2. Go to Admin centers → SharePoint from the left navigation.
      The SharePoint admin center page appears.
    3. Change the SharePoint admin center URL to {sharepoint_admin_site}/_layouts/15/AppInv.aspx in the address bar, for example, change https://example-admin.sharepoint.com/_layouts/15/online/AdminHome.aspx#/home to https://example-admin.sharepoint.com/_layouts/15/AppInv.aspx, and then open the URL.
    4. On the screen that appears, copy and paste the App Id assigned in step 7 in the App Id field and then click Lookup.
      The Title field is automatically filled.
    5. Copy and paste tmcas.trendmicro.com in the App Domain field.
    6. Enter {Cloud App Security_admin_site}/provision.html in the Redirect URL field based on your serving site.
      For example, if the URL of your Trend Vision One console in the address bar is "https://portal.xdr.trendmicro.com" after logon, enter https://portal.xdr.trendmicro.com/ui/cas/provision.html in the Redirect URL field.
    7. Copy and paste the following information in the Permission Request XML field:
      <AppPermissionRequests AllowAppOnlyPolicy="true">
<AppPermissionRequest Scope="http://sharepoint/content/tenant" Right="Manage" />
</AppPermissionRequests>
    8. Click Create, and on the screen that appears, click Trust It.
      The SharePoint admin center page appears.
    9. Change the SharePoint admin center URL to {sharepoint_admin_site}/_layouts/15/TA_AllAppPrincipals.aspx and then open the URL to verify the permission.
      If an item named Trend Micro Cloud App Security for MS Teams appears, the permission is successfully granted.
  9. Wait until the process is completed.
    If the message "Successfully created a service account and synced data." appears on the screen, the access grant is successful.
