With Exchange 2013 a conceptual change was introduced. Every CU will revert most of your customization, which forces you to apply changes each time after an upgrade. Manual steps are error prone, scripts are good, but how about something you setup one time and almost forget about it? DSC also help you to stay compliant based on your policies. But DSC is not only for on-premises: There is much more available for your M365 environment! This session will provide you a brief overview of DSC and how to configure Exchange servers via DSC.
