Set-HybridMailflow

The Set-HybridMailflow cmdlet supports the configuration of message transport settings for hybrid deployments created with the Hybrid Configuration wizard offered in Exchange 2010 SP2. This cmdlet isn't typically used by administrators; therefore, we strongly recommend that it only be used as part of the hybrid configuration process using the Hybrid Configuration wizard.

CertificateSubject

Optional

System.String

The CertificateSubject parameter specifies the principal name of the certificate used for secure mail flow between the on-premises Exchange and Exchange Online organizations.

Confirm

The Confirm switch causes the command to pause processing and requires you to acknowledge what the command will do before processing continues. You don't have to specify a value with the Confirm switch.

InboundIPs

Optional

Microsoft.Exchange.Data.IPRange[]

The InboundIPs parameter specifies the IP addresses of the on-premises mail transport servers configured as part of the hybrid deployment. These must point to either Exchange 2010 SP2 Hub Transport or Edge Transport servers.

Optional

Microsoft.Exchange.Data.Fqdn
