Enable-UMService
This cmdlet is available only in on-premises Exchange.
Use the Enable-UMService cmdlet to set the status of an Exchange Server 2010 Unified Messaging (UM) server to enabled. This setting enables the Unified Messaging server to process UM calls.
You can run this cmdlet in Exchange 2013 or Exchange 2016, but the target server must be an Exchange 2010 UM server. You can't use this cmdlet to enable the UM service on Exchange 2013 or Exchange 2016 Mailbox servers.
For information about the parameter sets in the Syntax section below, see Exchange cmdlet syntax.

Enable-UMService

[-Confirm]
[-DomainController <Fqdn>]
[-WhatIf]
[<CommonParameters>]
Description
The Enable-UMService cmdlet sets the status of an Exchange server running the Unified Messaging server role. A UM server has a logical status variable controlled using the enable and disable cmdlets. A UM server doesn't process any new calls unless it's in the enabled state. With the status variable, you can start or stop call processing on a UM server so the UM server can be brought online or taken offline in a controlled way.
After this task is completed, the UM server is available to answer incoming calls.
You need to be assigned permissions before you can run this cmdlet. Although this article lists all parameters for the cmdlet, you might not have access to some parameters if they aren't 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
Enable-UMService -Identity MyUMServer
This example enables Unified Messaging on the UM server MyUMServer.
Parameters
-Confirm
Applicable: Exchange Server 2013, Exchange Server 2016
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.
