Lync conversation history is blocked by corporate policy, but I've found a client side library whcih can hook into the messages as they arrive and save them to a file. Great.
What I'd like to know is if its possible to fill the conversation window with some of this saved history when the conversation window is opened with that person again.
The Conversation.BeginMerge option seems promising but you need a conversation to merge in, and the only way I can see to create a conversation actually starts a conversation again (ie starts sending messages) and even afterwards when I call the merge method nothing seems to get merged in, I just seem to get an error in the lync conversation window
So is it possible to 'backfill' the conversation window with some history when the conversation window starts up, but not to resend all those messages?
