If you have a look in your Threat Management policies in Security and Compliance you’ll see a new tile called Configuration Analyzer as shown above. The direct URL is:
https://protection.office.com/configurationAnalyzer
When you select this tile you’ll see a screen like that shown above which compares your current policy settings to Microsoft best practices.
If you expand any of the headings you’ll the settings in question and what the recommendation is on the right. You’ll also see a link that allows you to easily Adopt this setting.
If you do select the Adopt link, you’ll be presented with the above warning asking you whether you wish to proceed and Confirm or Cancel the change.
