This cmdlet is available only in the cloud-based service.
Use the Get-PerimeterConfig cmdlet to view the list of gateway server and internal mail server IP addresses that have been added to the cloud-based safelists.
If you have an on-premises messaging system, you can add the IP addresses of your mail servers to cloud-based safelists. Safelists are also known as whitelists. You add IP addresses to cloud-based safelists to make sure that e-mail that originates in your on-premises messaging system isn't treated as spam.
This parameter is reserved for internal Microsoft use.
