Anyone with “admin” permissions can take over ownership of a group folder by simply moving the folder to their “My Stuff – Home”. They will automatically become the new owner of the folder.
If you don’t have an admin, and you have no way of granting someone admin privileges, here is an alternative way to transfer folder ownership.
To transfer folder ownership from User A to User B:
1. User B create a new folder, and make it a group folder
2. User B invite User A to join the group folder with “add” or “edit” access.
3. Now login as User A and move or copy any folders or items from User A’s account into User B’s group folder.
User B is now the new owner of that content. They can then move those subfolders wherever they’d like in their My Stuff.
