Remarks
Message
stores generate and maintain the PR_ATTACH_NUM property. The attachment number
is the secondary sort key, after the rendering position, in the attachment
table.
PR_ATTACH_NUM
is used to open the attachment with the IMessage::OpenAttach method. Within a client
application s session, the PR_ATTACH_NUM property of a message attachment
remains constant as long as the attachment table is open.
The message
store propagates changes to the table using the IMessage::CreateAttach
and IMessage::DeleteAttach methods. At its option the message store can
generate table notifications on open attachment tables so that clients can
resynchronize to those changes.
