When making bulk data changes to SharePoint List or Library you may need to temporarily turn off Required fields. Opening this can allow us to import records, apply changes, and modify metadata without prompting that required fields are missing. PowerShell below can help disable all Required fields OFF. Script generates a CSV snapshot of prior configuration during run. CSV can be used to restore original configuration for which fields are Required.
