Receiving a RopOpenMessage ROP Request

The Message object returned by the RopOpenMessage ROP ([MS-OXCROPS] section is used in subsequent ROPs, such as a RopGetPropertiesSpecific ROP request ([MS-OXCROPS] section For information about which ROPs operate on Message objects, see the specific ROPs in [MS-OXCROPS].

When the server receives multiple requests to open the same Message object, it returns a different handle and maintains a separate transaction for each.

A RopOpenMessage ROP MUST NOT succeed if a Message object with the specified ID does not exist or if the client has insufficient access rights to the folder in which the Message object is stored.

If the OpenModeFlag field includes the OpenSoftDeleted flag, the RopOpenMessage ROP provides access to all Message objects, including soft deleted Message objects. If the OpenSoftDeleted flag is not included, the server MUST NOT provide access to soft deleted Message objects.

The response field RecipientCount indicates the current number of recipients (2) in the message. In addition, the server returns data for as many recipients (2) as will fit in the response buffer, in the order of the value of the RowId field. The data for each recipient (2) is encoded as an OpenRecipientRow structure in the RecipientRows field. The response field RowCount indicates how many recipients (2) are present in the RecipientRows field.

If a server does not recognize a message class, it reverts to acting on all but the last group, recursively, until a recognized form remains.
