Remove-AttachmentFilterEntry

 

Applies to: Exchange Server 2013

Topic Last Modified: 2014-01-11

This cmdlet is available or effective only on an Edge Transport server.

Use the Remove-AttachmentFilterEntry cmdlet to remove an entry from the attachment filter list that's used by the Attachment Filtering agent on Edge Transport servers.

Remove-Attachmentfilterentry -Identity <String> [-Confirm [<SwitchParameter>]] [-DomainController <Fqdn>] [-WhatIf [<SwitchParameter>]]

This example removes the attachment filter entry that filters file names with a .txt extension.

Remove-AttachmentFilterEntry -Identity FileName:*.txt

This example removes the attachment filter entry that filters attachments that have the MIME content type image/jpeg.

Remove-AttachmentFilterEntry -Identity ContentType:image/jpeg

On Edge Transport servers, the Attachment Filtering agent blocks attachments in messages based on the content type and the file name of the attachment. The configuration of the Attachment Filtering agent determines how messages that contain the specified attachments are processed. For more information about how to configure the Attachment Filtering agent, see Set-AttachmentFilterListConfig.

Parameter Required Type Description

Identity

Required

System.String

The Identity parameter specifies the type of attachment that this filter entry removes. The Identity parameter accepts values in the format Type:Name, where Type is one of the following two values:

  • ContentType   This value matches the attachment filter entry against the MIME content type.

  • FileName   This value matches the attachment filter entry against the simple file name.

In Type:Name, Name can be either the file name of the attachment filter entry to be removed, or the content type of the attachment filter entry to be removed.

Confirm

Optional

System.Management.Automation.SwitchParameter

The Confirm switch can be used to suppress the confirmation prompt that appears by default when this cmdlet is run. To suppress the confirmation prompt, use the syntax -Confirm:$False. You must include a colon ( : ) in the syntax.

DomainController

Optional

Microsoft.Exchange.Data.Fqdn

The DomainController parameter specifies the fully qualified domain name (FQDN) of the domain controller that writes this configuration change to Active Directory.

WhatIf

Optional

System.Management.Automation.SwitchParameter

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.
