Eventsink: cause of EVT_REPLICATED_ITEM Event

[lsman11]

Hello,

I have an Eventsink for Exchange 2003, and i am wondering on what cases would a EVT_REPLICATED_ITEM to occurr on the onSave method? The description from MSDN states:

The item is being replicated from another location.

But that is still unclear to me, can someone provide 1 or 2 use cases of this?

Thanks very much,
LSM
