2.2.2 Identifiers for Special Folders

The value that identifies a special folder is obtained from one of the following:

  • The folder IDs (FIDs) ([MS-OXCDATA] section 2.2.1.1) returned in a RopLogon remote operation (ROP) response ([MS-OXCROPS] section 2.2.3.1), as specified in [MS-OXCSTOR] section 2.2.1.1.3. These FIDs identify the following folders: Root folder, Finder folder, Top of Personal Folders folder, Deleted Items folder, Outbox folder, Sent Items folder, Inbox folder, Common Views folder, Personal Views folder, and Deferred Action folder.

  • One of several binary properties on the Root folder or the Inbox folder. Each property contains only a single entry ID. For more details, see section 2.2.3.

  • The PidTagAdditionalRenEntryIds property (section 2.2.4) on the Inbox folder. The property contains an array of entry IDs.

  • The PidTagAdditionalRenEntryIdsEx property (section 2.2.5) on the Store object. The property contains binary data is in its own format, allowing for multiple entry IDs.

  • The PidTagFreeBusyEntryIds property (section 2.2.6) on the Root folder or the Inbox folder. Indexed value 3 contains the entry ID for the Freebusy Data folder.

  • The FID returned by the RopGetReceiveFolder ROP response ([MS-OXCROPS] section 2.2.3.2). This FID is for the folder that is set to be the Receive folder. For details about setting the Receive folder, see [MS-OXCSTOR].

Unless otherwise noted, the entry IDs MUST be converted to FIDs by using the RopIdFromLongTermId ROP ([MS-OXCROPS] section 2.2.3.9) before they are used with the Folder Object Protocol, as specified in [MS-OXCFOLD], to open a special folder.
