1. On your Office 365 dashboard click on the “Admin” menu.

2. Click on the “Exchange” menu item.

3. Click on “permissions” and double click on “Discovery Management…”.

4. Add the “ApplicationImpersonation” Role to this roles group and click on “Save”.

5. Click on “permissions” and double click on ”Organization Management …”
