Using my Office 365 subscription, I upgraded to Office 2016. Now, I had been running the preview for quite some time on my test system, so I knew what to expect. I was surprised to find that the installer removed Skype for Business and then I was unable to re-install it. I tried installing Skype for Business from my Office 365 portal but received an error indicating that my version of office was newer than Skype for Business and therefore wasn’t compatible.

Some initial searching didn’t turn up much. Thanks to Mary Joe Foley’s posting over at allaboutmicrosoft.com, I was able to get Skype for Business installed and working again. You can read Mary Joe’s article for more information. The Microsoft support article that she refers to is here.
