The command shown in Example 1 creates a new collection of push notification settings for the Redmond site, and enables push notifications from both the Apple Push Notification Service and the Microsoft Push Notification Service. The latter is done by setting both the EnableApplePushNotificationService and the EnableMicrosoftPushNotificationService properties to True.

New-CsPushNotificationConfiguration -Identity "site:Redmond" -EnableApplePushNotificationService $True -EnableMicrosoftPushNotificationService -$True

Example 2 shows how you can create a set of push configuration settings for each of your Lync Server sites. To do this, the command first uses the Get-CsSite cmdlet to return a collection of all your Lync Server sites. That collection is then piped to the ForEach-Object cmdlet, which takes each site in the collection, calls the New-CsPushNotificationConfiguration cmdlet, and creates a new set of push notification configuration settings for that site. Note that this command will fail for any site that already hosts a collection of push notification configuration settings.

	Copy Code
Get-CsSite | ForEach-Object {New-CsPushConfigurationNotification -Identity $_.Identity}

Example 3 demonstrates the use of the InMemory parameter to create a collection of push notification configuration settings that initially exist only in memory. To do this, the example creates a new collection of settings (with the Identity site:Redmond) and stores this collection in a variable named $x. Note that, after this first command executes, the collection exists only in memory; if you run the Get-CsPushNotificationConfiguration cmdlet, you will not see an entry for site:Redmond.

In the next two commands, both the EnableApplePushNotificationService and the EnableMicrosoftPushNotificationService properties for this virtual collection of settings are set to True, which enables push notifications from both the Apple Push Notification Service and the Microsoft Push Notification Service. Finally, the last command uses the Set-CsPushNotificationConfiguration cmdlet to transform the virtual push notification settings into an actual collection of settings applied to the Redmond site. If you do not call the Set-CsPushNotificationConfiguration cmdlet, these settings will remain in memory only and will disappear when your Windows PowerShell session is terminated or the variable $x is deleted.

$x = New-CsPushNotificationConfiguration -Identity "site:Redmond" -InMemory $x.EnableApplePushNotificationService = $True $x.EnableMicrosoftPushNotificationService = $True Set-CsPushNotificationConfiguration -Instance $x
