Use the New-UMMailboxPolicy cmdlet to create a Unified Messaging (UM) mailbox policy.

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

New-UMMailboxPolicy -Name <String> -UMDialPlan <UMDialPlanIdParameter> [-Confirm [<SwitchParameter>]] [-DomainController <Fqdn>] [-Organization <OrganizationIdParameter>] [-SharedUMDialPlan <SwitchParameter>] [-WhatIf [<SwitchParameter>]]

This example creates the UM mailbox policy MyUMMailboxPolicy associated with the UM dial plan MyUMDialPlan.

New-UMMailboxPolicy -Name MyUMMailboxPolicy -UMDialPlan MyUMDialPlan

The New-UMMailboxPolicy cmdlet creates a UM mailbox policy that has organization-wide scope. UM mailbox policies provide a set of policy values to be applied to UM-enabled users associated with a particular UM dial plan. UM mailbox policies are directly associated with UM dial plans. Therefore, the settings contained within a UM mailbox policy apply only to UM-enabled users of the UM dial plan that the UM mailbox policy is associated with. You can also use the New-UMMailboxPolicy cmdlet to create a UM mailbox policy template that can be used to create additional UM mailbox policies.

After this task is completed, a new UM mailbox policy is created.

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 "UM mailbox policies" entry in the Unified Messaging permissions topic.


Parameter Required Type Description




The Name parameter specifies the display name for the UM mailbox policy. The name for the UM mailbox policy can contain as many as 64 characters.




The UMDialPlan parameter specifies the identifier for the UM dial plan to be associated with the UM mailbox policy. This parameter is the directory object ID for the UM dial plan.




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.




The Organization parameter is reserved for internal Microsoft use.




The SharedUMDialPlan switch specifies whether the new UM mailbox policy being created is linked or associated with a dial plan outside the scope of the organization. If you specify this parameter, the UM mailbox policy can be linked with another tenant's dial plan. This parameter is used during tenant provisioning and is only used in a data center.




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.
