We use Skype for Business but we're currently unable to review the chat logs and receive mobile updates (for instance, updates to a group conversation) on our mobile devices. At my last place of employment I was able to do both. My question is, are there some changes to our environment we would would need to make in order to enable both features? For instance, will these features ONLY work if there's some sort of VPN client running on the mobile device? Does the customer have to host Skype internally?
If there's a URL that describes the requirements I'd be glad to review them.
