You can stop sharing an item, or change the permissions others have to it, if you’re the owner of the item or have edit permissions.
Here are the steps:
- Select the item you want (In tile view, select the circle in the upper corner of the shared item.), and then select the Information icon on the bar at the top of the page.
- In the Details pane, scroll down to the Sharing section and expand the section to see what’s inside.
- To stop sharing a link, select the X next to a link to disable it.
To stop sharing with a person or group, select that person or group’s permissions, and then select Stop sharing. To change a person or group’s permissions between editing and only viewing, select the permissions you want to change.
