Fix "The requested operation is part of an experimental feature that is not supported in the current environment." Error

Problem: When trying to run a PowerShell cmdlet, got this error message: "The requested operation is part of an experimental feature that is not supported in the current environment." If a new feature is not yet rolled out for your tenant, SharePoint shows this error.

Solution: Set the release preference in Office 365.

• Go to your Office 365 Admin Center >> Click on "Settings" from left navigation >> Click on "Organisation Profile"
• In Organization profile page, Click on "Edit" button net to "Release Preferences"
  
• Change the release preference to "Targeted release for everyone" and confirm the prompt on next page.
  

You may need to wait for sometime for the changes to take effect!
