Parameters

When sending instant messages, users can attach and send files to the other participants in the conversation. Microsoft Lync Server 2010 can be configured so that files with certain extensions--typically extensions of file types that could potentially prove harmful--are not allowed to be sent using a Lync Server 2010 client.

The Remove-CsFileTransferFilterConfiguration cmdlet enables you to delete a file transfer filter configuration. For configurations at the site scope, Remove-CsFileTransferFilterConfiguration will remove the configuration; in turn, the users on the site will automatically inherit the global file transfer filter configuration. Remove-CsFileTransferFilterConfiguration can also be run against the global configuration. In that case, however, the global configuration will not be removed; instead, all the property values in that configuration will be reset to their default values.

Who can run this cmdlet: By default, members of the following groups are authorized to run the Remove-CsFileTransferFilterConfiguration 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-CsFileTransferFilterConfiguration"}

Microsoft.Rtc.Management.WritableConfig.Settings.ImFilter.FileTransferFilterConfiguration object. Accepts pipelined input of file transfer filter configuration objects.

This cmdlet does not return a value or object. Instead, it removes instances of the Microsoft.Rtc.Management.WritableConfig.Settings.ImFilter.FileTransferFilterConfiguration object.

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

	Copy Code
Remove-CsFileTransferFilterConfiguration -Identity site:Redmond

In the preceding example, Remove-CsFileTransferFilterConfiguration is used to remove the file transfer filter configuration that has the Identity site:Redmond.

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

	Copy Code
Get-CsFileTransferFilterConfiguration -Filter site:* | Remove-CsFileTransferFilterConfiguration

In Example 2, all the file transfer filter configurations at the site scope are removed. To carry out this task, the command first uses Get-CsFileTransferFilterConfiguration and the Filter parameter to return all the configurations at the site scope. The filter value "site:*" tells Get-CsFileTransferFilterConfiguration to return only those configurations that have an Identity that begins with the string value "site:". The filtered collection of configurations is then piped to Remove-CsFileTransferFilterConfiguration, which deletes each item in the collection.

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

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

Example 3 shows you how you can remove all the file transfer filter configurations that are currently disabled. To do this, the command first uses Get-CsFileTransferFilterConfiguration to return a collection of all the file transfer filter configurations currently in use in the organization. That information is then piped to the Where-Object cmdlet, which selects only those file transfer filter configurations where the Enabled property is equal to (-eq) False ($False). That filtered collection is then piped to Remove-CsFileTransferFilterConfiguration, which proceeds to remove each item in the filtered collection.
