I have an on-premises Exchange 2013 server, Office 2013. My Skype for Business is in O365. I've been asked about having Outlook integration with Skype. I'm using DirSync for credentials.
My google-fu has failed me. I've found a bunch of tutorials about integrating 2013 and Skype for Business Server 2015, but not an on-prem Exchange and 'cloud' Skype.
Anyone have any good links, advice, warnings, etc.?
Edit: and to be honest, I don't know jack about these integrations. Just been told that there was some type of functionality they had at a previous employer and need to research it.
