I have an enterprise portal in collaboration with my AGO account. I would like all of my collaborated items from AGE to send and receive in AGO but none of my items to go the other direction - AGO to AGE.
AGE (Send and receive) to AGO - YES
AGO (Send and receive) to AGE - NO.
Right now everything in both folder workspaces is shared in both directions.
The collaboration host can set the access to send only, receive only, or send and receive.
