Description

On Edge Transport servers, the Attachment Filtering agent blocks attachments in messages based on the content type or the file name of the attachment. The configuration of the Attachment Filtering agent determines how messages that contain the specified attachments are processed.

On Edge Transport servers, you need to be a member of the local Administrators group to run this cmdlet.

Examples

Example 1

Set-AttachmentFilterListConfig -Action Reject

This example modifies the action that the Attachment Filtering agent takes on an attachment that matches an entry on the attachment filter list so that both the email message and attachment aren't delivered to the recipient and an NDR is sent to the sender.

Parameters

-Action

The Action parameter specifies how the Attachment Filtering agent handles an attachment that matches an entry on the attachment filter list. Valid values are:

  • Reject: This value prevents both the email message and attachment from being delivered to the recipient and issues a non-delivery report (NDR) to the sender. This is the default value.
  • Strip: This value removes the offending attachment from the email message and allows the message and other attachments that don't match an entry on the attachment filter list through. A notification that the attachment was removed is added to the email message.
  • SilentDelete: This value prevents both the email message and the attachment from being delivered to the recipient. No notification that the email message and attachment were blocked is sent to the sender.
Type:FilterActions
Position:Named
Default value:None
Required:False
Accept pipeline input:False
Accept wildcard characters:False
Applies to:Exchange Server 2010, Exchange Server 2013, Exchange Server 2016, Exchange Server 2019

-AdminMessage

The AdminMessage parameter specifies the content of a text file that replaces attachments removed by the Attachment Filtering agent. The AdminMessage parameter only appears when the Attachment Filtering agent is configured to remove an attachment that's been identified as bad.

Type:String
Position:Named
Default value:None
Required:False
Accept pipeline input:False
Accept wildcard characters:False
Applies to:Exchange Server 2010, Exchange Server 2013, Exchange Server 2016, Exchange Server 2019

-Confirm

The Confirm switch specifies whether to show or hide the confirmation prompt. How this switch affects the cmdlet depends on if the cmdlet requires confirmation before proceeding.

  • Destructive cmdlets (for example, Remove-* cmdlets) have a built-in pause that forces you to acknowledge the command before proceeding. For these cmdlets, you can skip the confirmation prompt by using this exact syntax: -Confirm:$false.
  • Most other cmdlets (for example, New-* and Set-* cmdlets) don't have a built-in pause. For these cmdlets, specifying the Confirm switch without a value introduces a pause that forces you acknowledge the command before proceeding.

-DomainController

The DomainController parameter specifies the domain controller that's used by this cmdlet to read data from or write data to Active Directory. You identify the domain controller by its fully qualified domain name (FQDN). For example, dc01.contoso.com.

The DomainController parameter isn't supported on Edge Transport servers. An Edge Transport server uses the local instance of Active Directory Lightweight Directory Services (AD LDS) to read and write data.

Type:Fqdn
Position:Named
Default value:None
Required:False
Accept pipeline input:False
Accept wildcard characters:False
Applies to:Exchange Server 2010, Exchange Server 2013, Exchange Server 2016, Exchange Server 2019

-ExceptionConnectors

The ExceptionConnectors parameter specifies a list of connectors that should be excluded from attachment filtering. Attachment filters aren't applied to email messages received through these connectors. You must use the connector GUID to specify the ExceptionConnectors parameter value.

Type:MultiValuedProperty
Position:Named
Default value:None
Required:False
Accept pipeline input:False
Accept wildcard characters:False
Applies to:Exchange Server 2010, Exchange Server 2013, Exchange Server 2016, Exchange Server 2019

-RejectResponse

The RejectResponse parameter specifies the message body that you want delivered in the NDR to senders whose messages contain an attachment that's blocked. The RejectResponse parameter is required only if you set the Action parameter to Reject. Don't exceed 240 characters in the parameter argument. When you pass an argument, you must enclose the RejectResponse parameter value in quotation marks (") if the phrase contains spaces, for example: "Message rejected". The default setting is Message rejected due to unacceptable attachments.

Type:String
Position:Named
Default value:None
Required:False
Accept pipeline input:False
Accept wildcard characters:False
Applies to:Exchange Server 2010, Exchange Server 2013, Exchange Server 2016, Exchange Server 2019

-WhatIf

The WhatIf switch simulates the actions of the command. You can use this switch to view the changes that would occur without actually applying those changes. You don't need to specify a value with this switch.
