Server-side conversation history in Skype for Business

1. How Conversation history function in previous versions

Conversation History in Lync Server 2013 was device-specific. It stored a record of your conversations in the Lync 2013 client, and in an Outlook folder labeled “Conversation History”, depending on which device you used for that conversation. You’re on a laptop, you get a log in the Conversation History folder. You’re on your phone, you get a log in your phone’s Lync client. 

Whatever the conversation we made from mobile device will not be stored in outlook's conversation history folder and vice versa.

2. What we have in SfB

Now with Skype for Business, instead of device-specific storage, all Conversation History is stored server-side. Which means that all your devices can see the same Conversation History.
