   If you decide to perform step 7 later, you can find the App Id under the corresponding Authorized Account from Administration → Service Account.

   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 6 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 {Trend_Vision_One_site}/ui/cas/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.
