Description

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.

You need to be assigned permissions before you can run this cmdlet. Although this topic lists all parameters for the cmdlet, you may not have access to some parameters if they're not included in the permissions assigned to you. To find the permissions required to run any cmdlet or parameter in your organization, see Find the permissions required to run any Exchange cmdlet.

Examples

Example 1

Set-HybridMailflow

This example configures the message transport settings in the EOP service for a hybrid deployment.

Parameters

-CentralizedTransportEnabled

The CentralizedTransportEnabled parameter specifies that the Exchange Online organization routes all outbound mail messages to external recipients to the on-premises Exchange organization. The on-premises Exchange organization then routes the messages to the external recipients. The valid input for the CentralizedTransportEnabled parameter is $true or $false. The default value is $true.

Type:	Boolean
Position:	Named
Default value:	None
Required:	False
Accept pipeline input:	True
Accept wildcard characters:	False
Applies to:	Exchange Online

-CertificateSubject

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

Type:	String
Position:	Named
Default value:	None
Required:	False
Accept pipeline input:	True
Accept wildcard characters:	False
Applies to:	Exchange Online

-Confirm

The Confirm switch specifies whether to show or hide the confirmation prompt. How this switch affects the cmdlet depends on if the cmdlet requires confirmation before proceeding.

Destructive cmdlets (for example, Remove-* cmdlets) have a built-in pause that forces you to acknowledge the command before proceeding. For these cmdlets, you can skip the confirmation prompt by using this exact syntax: -Confirm:$false.
Most other cmdlets (for example, New-* and Set-* cmdlets) don't have a built-in pause. For these cmdlets, specifying the Confirm switch without a value introduces a pause that forces you acknowledge the command before proceeding.

Type:	SwitchParameter
Aliases:	cf
Position:	Named
Default value:	None
Required:	False
Accept pipeline input:	False
Accept wildcard characters:	False
Applies to:	Exchange Online

-InboundIPs

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.

Type:	IPRange[]
Position:	Named
Default value:	None
Required:	False
Accept pipeline input:	True
Accept wildcard characters:	False
Applies to:	Exchange Online

-OnPremisesFQDN

The OnPremisesFQDN parameter specifies the fully qualified domain name (FQDN) of the outbound smart host in the on-premises Exchange organization to use for centralized transport. This is either an on-premises Exchange 2010 SP2 Hub Transport or Edge Transport server.

Type:	Fqdn
Position:	Named
Default value:	None
Required:	False
Accept pipeline input:	True
Accept wildcard characters:	False
Applies to:	Exchange Online

-OutboundDomains

The OutboundDomains parameter specifies SMTP domains configured for the hybrid deployment.

Type:	SmtpDomainWithSubdomains[]
Position:	Named
Default value:	None
Required:	False
Accept pipeline input:	True

-SecureMailEnabled

The SecureMailEnabled parameter specifies that all messages sent between the on-premises Exchange and the Exchange Online organizations must use the Transport Layer Security (TLS) protocol and the assigned digital certificate. The valid input for the SecureMailEnabled parameter is $true or $false. The default value is $true.

Type:	Boolean
Position:	Named
Default value:	None
Required:	False
Accept pipeline input:	True
