The Exchange Access and Operation Permissions Protocol is used by a client to retrieve and to manage the permissions list on a folder by using remote operations (ROPs). Each entry in this list specifies the permissions granted to a single user. The user's permissions determine what actions the user is allowed on the folder. For example, a user can be allowed to view a folder but not allowed to modify the folder's properties.
The permissions list initially contains two reserved entries: an entry that specifies folder permissions for an anonymous user and an entry that specifies the default permissions for a user who is not currently included in the permissions list. For information about how these reserved entries are used, see section 220.127.116.11. Additional entries are added by an owner of the folder. Existing entries can be modified or deleted.
This protocol extends the Folder Object Protocol, described in [MS-OXCFOLD]. This protocol also extends the Availability Web Service Protocol, described in [MS-OXWAVLS], if both the client and server support the Availability Web Service Protocol.
