Download Message Header State

Last modified: July 23, 2011

Applies to: Outlook

This topic describes what happens during the download message header state of the replication state machine.

State Identifier:

LR_SYNC_DOWNLOAD_HEADER

Related Data Structure:

HDRSYNC

From this state:

Idle state

To this state:

Idle state

Note Note

The replication state machine is a deterministic state machine. A client departing from one state to another must eventually return to the former from the latter.

During this state, the client updates the header of a message on a local store. The local store enters this state upon IOSTX::SyncHdrBeg and exits when IOSTX::SyncHdrEnd is called. During this state, Outlook initializes members of the associated HDRSYNC data structure with information about the header of a message. The client first downloads the full message item from the server and then updates the header of the message item locally.

When syncrhonization ends, the client sets the download results. The local store returns to the idle state.
