Removes an existing server application. Server applications are applications that are hosted by Lync Server. This cmdlet was introduced in Lync Server 2010.


Remove-CsServerApplication -Identity <XdsIdentity> [-Confirm [<SwitchParameter>]] [-Force <SwitchParameter>] [-WhatIf [<SwitchParameter>]]



In Example 1, the server application that has the Identity service: is removed. Because Identities must be unique, this command will never delete more than a single application.

Copy Code
Remove-CsServerApplication -Identity ""


In Example 2, all the non-critical server applications are removed. To carry out this task, the command first calls the Get-CsServerApplication cmdlet in order to return a collection of all the server applications currently in use in the organization. This collection is then piped to the Where-Object cmdlet, which picks all the applications where the Critical property is equal to False. This filtered collection is then piped to the Remove-CsServerApplication cmdlet, which deletes each item in the collection.

Copy Code
Get-CsServerApplication | Where-Object {$_.Critical -eq $False} | Remove-CsServerApplication


Example 3 deletes all the server applications that have been configured for use by the service To do this, the Get-CsServerApplication cmdlet is used along with the Filter parameter; the filter value "*" returns all the applications that have an Identity that begins with the characters "". In turn, that collection is piped to the Remove-CsServerApplication cmdlet , which deletes each application from the

Copy Code
Get-CsServerApplication -Filter "*" | Remove-CsServerApplication

Detailed Description

Server applications refer to the individual programs that run under Lync Server. The Remove-CsServerApplication cmdlet provides a way for administrators to remove any application running as part of Lync Server. Note that deleting a server application is not the same thing as uninstalling that application. When you run the Remove-CsServerApplication cmdlet, the application no longer runs under Lync Server. However, the software itself is not uninstalled, and the application can be re-enabled by running the New-CsServerApplication cmdlet.

Who can run this cmdlet: By default, members of the following groups are authorized to run the Remove-CsServerApplication cmdlet locally: RTCUniversalServerAdmins. To return a list of all the role-based access control (RBAC) roles this cmdlet has been assigned to (including any custom RBAC roles you have created yourself), run the following command from the Windows PowerShell prompt:

Get-CsAdminRole | Where-Object {$_.Cmdlets –match "Remove-CsServerApplication }


Parameter Required Type Description
