This Permission has been deactivated (via enterprise configuration) for ESDC's tenant of M365. This Permission might have been used to: 1. Share with other GC Departments, Partners, etc. 2. Share with System Integrators who may not have an ESDC Network Account 3. Share with Public (use caution here). There should be a strong Use Case here, with permissions set only at the lowest-level folder, to ensure permissions are not inherited by mistake.
