Applies to: Exchange Server 2013

This cmdlet is available only in on-premises Exchange Server 2013.

Use the New-SearchDocumentFormat cmdlet to add a format-specific filter to those used by Exchange search.

For information about the parameter sets in the Syntax section below, see Syntax.

New-SearchDocumentFormat -Extension <String> -Identity <SearchDocumentFormatId> -MimeType <String> -Name <String> [-Confirm [<SwitchParameter>]] [-Enabled <$true | $false>] [-Server <ServerIdParameter>] [-WhatIf [<SwitchParameter>]]

This example creates a new search document format with an extension of .sct and a MIME type of text/scriptlet.

New-SearchDocumentFormat -Name "Proprietary SCT Formats" -MimeType text/scriptlet -Extension .sct -Identity ProprietarySCT1

After running the New-SearchDocumentFormat cmdlet, your must run the following cmdlet to restart the search service. There will be a brief search outage.

You need to be assigned permissions before you can run this cmdlet.

To see what permissions you need, see the "Exchange Search - diagnostics" entry in the Recipients Permissions topic.


Parameter Required Type Description




The Extension parameter specifies the file type to be processed by the filter, and is designated by the common file extension associated with the file type. Examples include .MP3, .JPG, and .PNG. Note the leading period.




The Identity parameter uniquely identifies the new search document format. For example, an identity of "PropSCT" might specify a proprietary document format which is supported by a custom IFilter. The Identity parameter must be unique within the search document formats.




The MimeType parameter specifies the MIME type of the format.




The Name specifies a friendly name for the format, but does not need to be unique. For example, you might have several different formats (supported by custom IFilters) that are used to index output from a proprietary system called "My Business Output". You could use the Name parameter to create a category of formats called "My Business Output Formats", and uniquely identify each format within that group using the Identity parameter.




The Confirm switch causes the command to pause processing and requires you to acknowledge what the command will do before processing continues. You don't have to specify a value with the Confirm switch.




The Enabled parameter specifies whether the new format is enabled at creation.

Valid input for this parameter is $true or $false. The default is $true.




The Server parameter specifies the Exchange server on which you want to run this command. You can use any value that uniquely identifies the server. For example:

  • Name

  • FQDN

  • Distinguished name (DN)

  • Exchange Legacy DN

If you don't use the Server parameter, the command is run on the local server.




The WhatIf switch instructs the command to simulate the actions that it would take on the object. By using the WhatIf switch, you can view what changes would occur without having to apply any of those changes. You don't have to specify a value with the WhatIf switch.
