By default, all members of a Team Folder can access all its folders, subfolders, and based on their assigned roles. However, if you need to reduce a member's permission for a specific folder, or completely hide it from certain members or external collaborators, you can customize that folder’s permissions.

Only Team Folder Admins, Organizers and collaborators with organize access can create and manage customized folder and permissions.

Important notes on customized folder:

1. You can customize folders and sub-folders at any level within a Team Folder.
   
2. Team Folder roles and parent folder permissions do not apply to a customized folder.
   
3. You cannot lower a user's access on a customized folder if they already have a higher level of access from a parent folder (the higher access level always applies).
   
4. All underlying subfolders of a customized folder will automatically inherit the custom permissions you set.
   
5. Once a folder is customized, new members added to the Team Folder or parent folder will not have access by default and must be manually shared with.
   
6. Custom folder permissions are only available for Team Folders and are not supported in My Folders.
   
7. A team folder can have a maximum of 2,500 customized folders, created by all team members combined.
