Remove-CsHostingProvider -Identity <XdsGlobalRelativeIdentity> [-Confirm [<SwitchParameter>]] [-Force <SwitchParameter>] [-WhatIf [<SwitchParameter>]]

Parameters

Federation is a means by which two organizations can set up a trust relationship that facilitates communication between the two groups. When a federation has been established, users in the two organizations can send each other instant messages, subscribe for presence notifications, and otherwise communicate with one another using SIP applications such as Microsoft Communicator "14". Microsoft Communications Server 2010 allows for three types of federation: 1) direct federation between your organization and another; 2) federation between your organization and a public provider; and, 3) federation between your organization and a third-party hosting provider.

A hosting provider is an organization which provides SIP communication services for other organizations; for example, Fabrikam Hosting, Inc. might host users from Contoso, Northwind Traders, Wingtip Toys, and so on. When you establish a federation relationship with a hosting provider, you effectively establish federation with any organization hosted by that provider. For example, if you federate with Fabrikam Hosting, your users will be able to exchange instant messages and presence information with users from Contoso, Northwind Traders, and Wingtip Toys.

Hosting providers are also used in split domain scenarios. In a split domain scenario, some of your users have accounts hosted on-premises (that is, hosted on your local implementation of Communications Server 2010). Other users have their accounts hosted "in the cloud"; that is, those accounts are maintained off-premises by the third-party hosting provider. Federating with the hosting provider enables your on-premises and off-premises users to communicate with one another.

In order to federate with a third-party hosting provider you need to create and enable a new hosting provider. (In addition, the third-party provider will need to create a federation relationship with you.) If you decide later to terminate this relationship, you can use the Remove-CsHostingProvider cmdlet to delete the hosting provider. When you delete a hosting provider, the provider is removed from your list of federated partners; at that point, the only way to re-establish the relationship is to recreate the provider. If you want to temporarily suspend a relationship, use the Disable-CsHostingProvider cmdlet instead. When a hosting provider is disabled the provider is not deleted from the list of federated partners; instead, the provider is simply marked as disabled and communication between your organization and that provider is disabled. To re-establish the relationship you can use Enable-CsHostingProvider to re-enable the provider.

Note that you cannot federate with a hosting provider if your Access edge servers are configured to use default routing rather than DNS server routing. For more information, type "Get-Help Set-CsAccessEdgeConfiguration" (without the quote marks) at the Windows PowerShell prompt.

Deletes instances of the Microsoft.Rtc.Management.WriteableConfig.Settings.Edge.DisplayHostingProvider object.

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

	Copy Code
Remove-CsHostingProvider -Identity "Fabrikam.com"

The command show in Example 1 deletes the hosting provider with the Identity Fabrikam.com. After the hosting provider has been deleted, federation with Fabrikam.com (and any domains associated with Fabrikam.com) will be terminated.

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

	Copy Code
Get-CsHostingProvider | Remove-CsHostingProvider

Example 2 deletes all of the hosting providers configured for use in the organization. To do this, the command first uses Get-CsHostingProvider to return a collection of all the hosting providers currently in use. That collection is then piped to Remove-CsHosting provider, which deletes each item in the collection. When this command completes there will no longer be any hosting providers configured for use in the organization.

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

	Copy Code
Get-CsHostingProvider -Filter "*Fabrikam*" | Remove-CsHostingProvider

The preceding command deletes any hosting providers where the string value "Fabrikam" appears somewhere in the provider Identity. To carry out this task, the command first calls Get-CsHostingProvider and the -Filter parameter; the filter value "*Fabrikam*" limits the returned data to any hosting providers that have "Fabrikam" somewhere in the Identity. For example, this command would return such providers as Fabrikam.com, Fabrikam.net, and FabrikamUsers.com. This filtered collection is then piped to Remove-CsHostingProvider, which proceeds to delete each item in the collection.

-------------------------- Example 4 ------------------------

	Copy Code
Get-CsHostingProvider | Where-Object {$_.VerificationLevel -ne "AlwaysVerifiable" | Remove-CsHostingProvider

In Example 4, all the hosting providers where the verification level is set to anything other than AlwaysVerifiable are deleted. This is done by first calling Get-CsHostingProvider without any additional parameters; that command returns a collection of all the hosting providers configured for use in the organization. The resulting collection is then piped to the Where-Object cmdlet, which picks out only those providers where the VerificationLevel property is not equal to (-new) AlwaysVerifiable. This filtered collection is then piped to Remove-CsHostingProvider, which removes each provider in the filtered collection.

-------------------------- Example 5 ------------------------

	Copy Code
Get-CsHostingProvider | Where-Object {$_.Enabled -eq $False | Remove-CsHostingProvider

The preceding command removes all the hosting providers that are current disabled. To do this, the command first uses Get-CsHostingProvider to return a collection of all the hosting providers configured for use in the organization. This collection is piped to Where-Object, which picks out only those providers that are disabled; that is, only those providers where the Enabled property is equal to (-eq) False ($False). This filtered collection is then piped to Remove-CsHostingProvider which, in turn, deletes each of the disabled hosting providers.
