This topic describes what happens during the upload read status state of the replication state machine.

State Identifier:


Related Data Structure:


From this state:

Upload table state

To this state:

Upload table 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 uploading the read status of items in a folder specified in a preceding upload table state. During this state, Outlook initializes the associated UPREAD data structure with information for those items in the folder whose read status has changed. The client then updates the read status of these items on the server as being read or unread.

When this state ends, Outlook clears the internal information about the item's read status, preventing the item's read status from being uploaded again. The local store returns to the upload table state.
