Processes in Microsoft 365 Insider for installing preview builds, activating subscriptions, and keeping apps up to date with the latest Insider features.
Hello BexBrougham ,
Thanks for your post in Microsoft Community. Regarding your description about “Skype for Business not working on Mac using Mojave 10.14.5”, Mac on 10.14 Mojave supports “Office 365/2019 - Build 16.17.0 or later; Office 2016 - Build 16.16.2 or later; Skype for Business 16.21.65 or later version.” So would like to suggest you to kindly check your skype for business version and also be sure that your Office apps are up-to-date.
As Skype for business doesn’t load in MAC, to check the version, open any other Office app and check if there’s any update releases for Skype for Business and update it and try to restart Mac and app.
