Note: Parameters in orange are optional.
FolderA Mapi.NET.Folder from which permissions are removed.

This cmdlet removes permissions from a folder.  

Not all message stores support folder permissions.  For example, PST files do not provide an ability to set folder permissions and attempts to use this cmdlet on folder in a PST will fail.

Only permissions that exist on Folder and match either the EntryID or address values provided will be removed.  If an EntryID or address is provided, but for which the folder does not have a permission, that value is ignored.
