SPJeff

Step by step demo how to Disable SPO Modern Comments with PowerShell automation. Useful for scenario where Communication site or Publishing portal has well moderated text and goal is to avoid user comments added by anyone on page footer. NOTE – Comments are DELETED when the disable executes. Attempts to re-enable comments again will show a blank thread (prior text comments not visible).

Cheers
