Hi Brolide,
In my opinion, you don’t
have to have SFB archiving enabled for server side conversation history
Based on my understanding server side conversation history means the conversation history will be saved to the Skype for Business Server. However, Skype
for business Server will sync these data to Exchange Server at last. It’s a new feature with the new Skype for Business Server
2015. In previous version of Lync Server, the mobile client cannot save the conversation history to User mailbox directly, all the conversation histories are saved on the local phone.
And now with the new feature, instead of device-specific storage, all Conversation History is stored server-side, which
means that all your devices can see the same Conversation History.

For SFB archiving please refer to

These conversation histories remain until you delete them – they are not removed automatically.
