RingCentral App - Manage File Sharing - Admin
1. Administrators can click their Profile picture and select Administration.
2. On the Administration page, click Manage on File Sharing.
The Manage File Sharing window will pop-up.
3. Toggle the button to turn ON / OFF which service you would allow or restrict, and then click Save.
NOTE: These services are ON by default.
These restrictions also apply to Guests. For example, email@example.com is a guest in a team owned by Acme Corp. Acme only allows files shared from Google Drive. Even though Funco has no file-sharing restrictions, when Dave goes to share a file in that team owned by Acme, Google Drive will be the only option available to him.
