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

State Identifier:


Related Data Structure:


From this state:

Synchronize state

To this state:

Synchronize 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.

This state initiates downloading a tree hierarchy of folders from a server to the local store.

Outlook initializes the associated DNHIER data structure with a pointer to the hierarchy. The client downloads the hierarchy, and inserts new folders or modifications to folders in the local store. The download process adopts Microsoft Exchange Incremental Change Synchronization (ICS). For more information on ICS, see ICS Evaluation Criteria.

When this state ends, the local store returns to the synchronize state.
