Info
You will only be allowed to add 10 external members at a time. For adding hundreds or thousands of external members, contact the IT Service Desk, 704-687-5500, to submit a request for the Google Administrators to do bulk Adds or Removes.
If adding members yourself, you will have to send a Welcome Message when adding external recipients. If you would like to add members without sending this message, please contact the IT Service Desk, 704-687-5500, to request Google Administrators add these members.
