  2. Do one of the following:
    • Create a Service Account User within your Office 365 Environment.
    • Configure a already migrated account.
  3. From the navigation tree, select Exchange > Admin Roles.
  4. In the role group dialog, provide a name for your Role Group (e.g. "EMS_Exchange_Impersonation").
  5. In Role, click the + icon to add the "Application Impersonation" Role.
  6. In Members, click the + icon and find your Exchange Service Account.
