Deletes an existing collection of push notification settings. The push notification service (Apple Push Notification Service and Microsoft Lync Server 2010 Push Notification Service) provides a way to send notifications about events such as new instant messages or new voice mail to mobile devices such as iPhones and Windows Phones, even if the Microsoft Lync 2010 application on those devices is currently suspended or running in the background.

Remove-CsPushNotificationConfiguration -Identity <XdsIdentity> [-Confirm [<SwitchParameter>]] [-Force <SwitchParameter>] [-Tenant <Nullable>] [-WhatIf [<SwitchParameter>]]

The Apple Push Notification Service and the Microsoft Lync Server 2010 Push Notification Service enable users running Lync 2010 on their Apple iPhone or Windows Phone to receive notifications about Lync 2010 events even when Lync 2010 is suspended or running in the background. For example, users can receive notice for events such as these:

- Invitations to a new instant messaging session or conference

- New instant messages

- New voice mail

Without the push notification service users would receive these notices only when Lync 2010 was in the foreground and serving as the active application.

Administrators have the ability to enable or disable push notifications for iPhone users and/or Windows Phone users. (By default, push notifications are disabled for both iPhone users and Windows Phone users.) Administrators can enable or disable push notifications at the global scope by using the Set-CsPushNotificationConfiguration cmdlet. They can also create custom push notification settings at the site scope by using the New-CsPushNotificationConfiguration cmdlet.

These custom settings can later be deleted by using the Remove-CsPushNotificationConfiguration cmdlet. If you delete settings configured at the site scope, then users in that site will automatically be managed by the global push notification settings.

Note that Remove-CsPushNotificationConfiguration can also be run against the global settings. If you do that, however, the global settings will not be removed; instead, the properties in the global settings will all be reset to their default values. In this case, that means that push notifications will be disabled from both the Apple Push Notification Service and the Microsoft Lync Server 2010 Push Notification Service.

Who can run this cmdlet: By default, members of the following groups are authorized to run the Remove-CsPushNotificationConfiguration cmdlet locally: RTCUniversalServerAdmins.


Parameter Required Type Description




Unique identifier for the collection of push notification configuration settings to be removed. To remove the global collection, use the following syntax:

-Identity global

Note that you cannot actually remove the global settings; instead, you can only reset the properties to their default values.

To remove a site collection, use syntax similar to this:

-Identity site:Redmond

You cannot use wildcards when specifying a policy Identity.




Suppresses the display of any non-fatal error message that might occur when running the command.




This parameter is reserved for use with Microsoft Office365.




Describes what would happen if you executed the command without actually executing the command.




Prompts you for confirmation before executing the command.

Microsoft.Rtc.Management.WriteableConfig.Settings.PushNotificationConfiguration.PushNotificationConfiguration. Remove-CsPushNotificationConfiguration accepts pipelined instances of the PushNotificationConfiguration object.

None. Instead, Remove-CsPushNotificationConfiguration deletes instances of the Microsoft.Rtc.Management.WriteableConfig.Settings.PushNotificationConfiguration.PushNotificationConfiguration object.

-------------------------- Example 1 --------------------------

Remove-CsPushNotificationConfiguration -Identity "site:Redmond"

The command shown in Example 1 deletes the collection of push notification settings assigned to the Redmond site.

-------------------------- Example 2 --------------------------

Get-CsPushNotificationConfiguration -Filter "site:*" | Remove-CsPushNotificationConfiguration

The preceding command deletes all the push notification settings configured at the site scope. To perform this task, the cmdlet first uses the Get-CsPushNotificationConfiguration cmdlet and the Filter parameter to return a collection of all the settings configured at the site scope; the filter value "site:*" limits the returned items to settings that have an Identity that begins with the string value "site:". The site-scoped settings are then piped to, and deleted by, the Remove-CsPushNotificationConfiguration cmdlet.

-------------------------- Example 3 --------------------------

Get-CsPushNotificationConfiguration | Where-Object {$_.EnableMicrosoftPushNotificationService -eq $False} | Remove-CsPushNotificationConfiguration

Example 3 shows you how can remove all the push notification configuration settings where push notifications from the Microsoft Lync Server 2010 Push Notification Service have been disabled. To do this, the command first uses Get-CsPushNotificationConfiguration to return a collection of all the push notification settings currently in use. That collection is then piped to the Where-Object cmdlet, which selects only those settings where the EnableMicrosoftPushNotificationService property is equal to (-eq) False. This filtered collection is then piped to Remove-CsPushNotificationConfiguration which, in turn, deletes each item in the collection.
