This topic no longer applies to the cloud-based service. It applies only to on-premises Exchange 2013. To see the current version of the topic that applies to the cloud-based service, change the (v=exchg.150) value in the URL to (v=exchg.160).

Use the New-OwaMailboxPolicy cmdlet to create Microsoft Outlook Web App mailbox policies.

For information about the parameter sets in the Syntax section below, see Syntax.

New-OwaMailboxPolicy -Name <String> [-Confirm [<SwitchParameter>]] [-DomainController <Fqdn>] [-IsDefault <SwitchParameter>] [-Organization <OrganizationIdParameter>] [-WhatIf [<SwitchParameter>]]

This example creates the Outlook Web App mailbox policy Corporate for the default organization.

New-OwaMailboxPolicy -Name Corporate

Use the Set-OwaMailboxPolicy cmdlet to configure the new policy.

Changes to Outlook Web App mailbox polices may take up to 60 minutes to take effect. In on-premises Exchange 2013, you can force an update by running the command IISRESET /noforce.

You need to be assigned permissions before you can run this cmdlet. Although all parameters for this cmdlet are listed in this topic, you may not have access to some parameters if they're not included in the permissions assigned to you. To see what permissions you need, see the "Outlook Web App mailbox policies" entry in the Clients and mobile devices permissions topic.


Parameter Required Type Description




The Name parameter specifies a name for the new policy.




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.




This parameter is available only in on-premises Exchange 2013.

The DomainController parameter specifies the fully qualified domain name (FQDN) of the domain controller that writes this configuration change to Active Directory.




This parameter isn't available in on-premises Exchange 2013.

The IsDefault parameter specifies whether this policy is the default policy. The default value is $false. If another policy is currently set as the default, setting this parameter replaces the old default policy with this policy.




This parameter is reserved for internal Microsoft use.




The WhatIf switch instructs the command to simulate the actions that it would take on the object. By using the WhatIf switch, you can view what changes would occur without having to apply any of those changes. You don't have to specify a value with the WhatIf switch.
