Add-AttachmentFilterEntry
This cmdlet is available or effective only on Edge Transport servers in on-premises Exchange.
Use the Add-AttachmentFilterEntry cmdlet to add an entry to the attachment filter list that's used by the Attachment Filtering agent on Edge Transport servers.
For information about the parameter sets in the Syntax section below, see Exchange cmdlet syntax.
Syntax
Add-AttachmentFilterEntry
-Name <String>
-Type <AttachmentType>
[-Confirm]
[-DomainController <Fqdn>]
[-WhatIf]
[<CommonParameters>] Description
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.
On Edge Transport servers, you need to be a member of the local Administrators group to run this cmdlet.
Examples
Example 1
Add-AttachmentFilterEntry -Name *.txt -Type FileNameThis example adds an attachment filter entry based on a file name. After running this command, the Attachment Filtering agent filters all attachments that have a .txt extension.
Example 2
Add-AttachmentFilterEntry -Name image/jpeg -Type ContentTypeThis example adds an attachment filter entry based on the MIME content type image/jpeg, which is a JPEG image binary file. After running this command, the Attachment Filtering agent filters all attachments of the MIME content type image/jpeg.
Parameters
-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.
