  • Can you check Access Request Setting allows Sharing for Folder and files under Site Permissions – SharePointer Jul 7 '17 at 21:33
  • the option is missing. I will see if something is turned off in settings – Garrett M Jul 11 '17 at 15:01
  • Well this is new. I had to enable outgoing email for this menu to show up. The ARS (Access Request Settings) are set to allow access requests. checking the document library. I can now share the library. However when i try to check who the document or library is shared with it still shows the above error. – Garrett M Jul 11 '17 at 15:14
