The conflict resolution policy to use when this method applies changes.

[in] pSourceChangeBatch

[in] pCallback

An object that receives event notifications during change application.

[in, out] pSyncSessionStatistics

Return code Description
S_OK
 The method succeeded.
Provider-determined error codes

Remarks

When a source change contains change unit changes, the destination provider must determine which, if any, change unit versions to include in the batch of destination versions that is sent to the change applier. This decision depends on the kind of change from the source provider and whether the item is marked as deleted on the destination replica.
