4.1.3.1 Open the Delegator Information Object

The client opens the Delegate Information object by using the message ID (MID), as described in [MS-OXCDATA] section 2.2.1.2, and the FID, as described in [MS-OXCDATA] section 2.2.1.1, which are the second entry and the fourth entry, respectively, in the PidTagFreeBusyEntryIds property ([MS-OXOSFLD] section 2.2.6). The value of the NormalizedSubject field (in the RopOpenMessage ROP response ([MS-OXCROPS] section 2.2.6.1)) can be examined to determine whether the intended object has been opened. In this case, the value is "LocalFreebusy", verifying that the operation opened the correct object.
