Applies to: Exchange Online, Exchange Server 2016

This cmdlet is available in on-premises Exchange Server 2016 and in the cloud-based service. Some parameters and settings may be exclusive to one environment or the other.

Use the New-UMAutoAttendant cmdlet to create a Unified Messaging (UM) auto attendant.

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

New-UMAutoAttendant -Name <String> -UMDialPlan <UMDialPlanIdParameter> [-Confirm [<SwitchParameter>]] [-DomainController <Fqdn>] [-DTMFFallbackAutoAttendant <UMAutoAttendantIdParameter>] [-PilotIdentifierList <MultiValuedProperty>] [-SpeechEnabled <$true | $false>] [-Status <Enabled | Disabled>] [-WhatIf [<SwitchParameter>]]

This example creates the UM auto attendant MyUMAutoAttendant that can accept incoming calls using the extension number 55000 but isn't speech-enabled.

New-UMAutoAttendant -Name MyUMAutoAttendant -UMDialPlan MyUMDialPlan -PilotIdentifierList 55000 -Status Enabled

This example creates the speech-enabled UM auto attendant MyUMAutoAttendant using the extension numbers 56000 and 56100 that can accept incoming calls.

New-UMAutoAttendant -Name MyUMAutoAttendant -UMDialPlan MyUMDialPlan -PilotIdentifierList 56000,56100 -SpeechEnabled $true -Status Enabled

The New-UMAutoAttendant cmdlet creates one or more UM auto attendants. UM auto attendants have a forest-wide scope in the configuration container in Active Directory. When you create a UM auto attendant, the auto attendant isn't speech-enabled or able to answer incoming calls by default. The auto attendant is linked to a single UM dial plan that contains a list of extension numbers. Linking the UM auto attendant to the UM dial plan enables the associated Mailbox servers to answer incoming calls using the UM auto attendant.

After this task is completed, a UM auto attendant 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 auto attendants" entry in the Unified Messaging permissions topic.


Parameter Required Type Description




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




The UMDialPlan parameter specifies the UM dial plan identifier for the UM dial plan to be associated with this UM auto attendant.




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.




This parameter is available only in on-premises Exchange 2016.

The DomainController parameter specifies the domain controller that's used by this cmdlet to read data from or write data to Active Directory. You identify the domain controller by its fully qualified domain name (FQDN). For example,




The DTMFFallbackAutoAttendant parameter specifies a secondary UM auto attendant. A secondary UM auto attendant can be used only if the SpeechEnabled parameter is set to $true.




The PilotIdentifierList parameter specifies a list of one or more pilot numbers. Pilot numbers route incoming calls to Mailbox servers. The calls are then answered by the UM auto attendant.




The SpeechEnabled parameter specifies whether the UM auto attendant is speech-enabled. The default value is $true. If this parameter is omitted, or if the value is $false, the UM auto attendant isn't speech-enabled.




The Status parameter specifies whether the UM auto attendant being created will be enabled. If this parameter isn't supplied, the UM auto attendant is created but left in a disabled state.




The WhatIf switch simulates the actions of the command. You can use this switch to view the changes that would occur without actually applying those changes. You don't need to specify a value with this switch.
