Hi @cmoses2,
Welcome to Box Community, and we understand that you’re looking for ways to prevent the existing collaborators from accessing the folders, we’re glad to help!
Rather than logging in as the user and removing collaborators one-by-one from the user's profile, Box provides a more efficient Admin-level tool called Content Manager that lets you manage collaborators directly — without needing to log in as the user and go through each folders just to remove collaborators.
Prior deleting the user and transferring his/her contents, here’s how you can remove collaborators via Content tab:
- Log in to Box.com and navigate to Admin Console> Content tab
- In Content Manager, select Users.
- Click the Expand control (▶) next to the departing user's name.
- Navigate the folder structure of items the user owns.
- Hover over an item and select Manage Collaborators (or select the item and choose Manage Collaborators from the top action bar).
- In the Collaborators dialog, you can:
- See all users and groups with access
- Identify whether access is direct or inherited from a parent folder.
- Change or remove collaborator permissions directly from the Permission column.
In reference to this, please visit this article.
Do you have additional questions regarding deleting managed users? Please feel free to reply in this thread.
Thanks for posting!
