I am trying to link contacts (and also to look up what the linked contacts are) via Exchange Web Services. So far, I have been able to retrieve this information using extended properties. Specifically, I am looking up the property PidLidContactLinkEntry.
See http://msdn.microsoft.com/en-ca/library/ee158201%28v=exchg.80%29.aspx
According to the documentation there, the links reference Address book EntryIDs. As far as I can tell, these are different than the given contact's Entry ID but seem to contain the contact's entry ID.
See http://msdn.microsoft.com/en-ca/library/ee160588%28v=exchg.80%29.aspx
Does anyone know how to handle this via EWS?
For the record, I am using the EWS Java API.
