This is usually caused by the Recommendation Request Notification being inactive.
 

To fix this,navigate to:

  1. onBoard > Settings > Notifications 
  2. Select Edit next to Recommendation Request (inactive) (the Title of this can be edited so this may differ for your School)
  3. Mark the Active checkbox
  4. Make any edits to the Reply Email (required to be entered)
  5. Subject and Body
  6. Click Save or Save & Exit
Note: If a request was sent to the wrong individual or if you need to resend the request to the same individual because the person lost the email, the User can resend the request from their checklist
