Description

Client version policies represent a collection of client version rules; in turn, client version rules are used to determine which client applications are allowed to log on to Skype for Business Server. When a user attempts to log on to Skype for Business Server, his or her client application sends a SIP header to the server; this header includes detailed information about the application itself, including the software's major version, minor version and build number. The version information included in the SIP header is then checked against a collection of client version rules to see if any rules apply to that particular application. If such a rule exists, Skype for Business Server will then take the action specified by the rule. For example, the rule might tell Skype for Business Server to allow the logon, to block it, or to allow the logon but then silently upgrade the client application to the latest version (for example, upgrade Communicator 2007 R2 to Skype for Business).

Client version policies, which can be applied at the global scope, the site scope, the service scope (Registrar service only), or the per-user scope, give you flexibility in determining which client applications can be used to access the system. For example, as a general rule you might want to prevent users from logging on to Skype for Business Server by using Communicator 2007 R2; that's because Communicator 2007 R2 does not support the same features and capabilities as Skype for Business Server. However, due to hardware or software conflicts you might also have a group of users who cannot upgrade to Skype for Business. In that case, you can create a separate rule -- and a separate client version policy -- that allows those users to log on from within Communicator 2007 R2.

You can create new policies by using the New-CsClientVersionPolicy cmdlet. These custom policies can later be removed by running the Remove-CsClientVersionPolicy cmdlet. When you remove a client version policy, users previously governed by that policy will automatically inherit the next policy in the management hierarchy. For example, if you delete a per-user policy, users will automatically be governed by the appropriate service policy. If no service policy exists, then users will be governed by the appropriate site policy. If no site policy exists, then users will be governed by the global policy.

Note that there will always be a global policy, meaning that no users will be left unmanaged by client version policies. Although you can run the Remove-CsClientVersionPolicy cmdlet against the global policy, the policy will not actually be deleted. Instead, all of the policy rules will be reset to their default values.

It's important to note that client version policies do not apply to federated users; instead, federated users are bound by the client version policies used in their own organization. For example, suppose a federated user uses client A, a client allowed by the federated organization. As long as the federated organization allows the use of client A, this user will be able to communicate with your organization using that client. This will be true even if your client version policy blocks the use of client A. Client version policies enforced in your organization do not override the client version policies used in a federated organization.

Examples

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

Remove-CsClientVersionPolicy -Identity site:Redmond

The command shown in Example 1 deletes the client version policy for the Redmond site.

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

Get-CsClientVersionPolicy -Filter tag:* | Remove-CsClientVersionPolicy

In Example 2, all of the client version policies configured at the per-user scope are deleted. To do this, the command first calls the Get-CsClientVersionPolicy cmdlet and includes the Filter parameter; the filter value "tag:*" limits the returned data to policies configured at the per-user scope. This filtered collection is then piped to the Remove-CsClientVersionPolicy cmdlet, which deletes each item in the collection.

Parameters

-Confirm
