Add-AttachmentFilterEntry

Exchange 2010
[This topic is in progress.]  

Applies to: Exchange Server 2010 SP3, Exchange Server 2010 SP2

Topic Last Modified: 2011-05-03

Use the Add-AttachmentFilterEntry cmdlet to add an entry to the attachment filter list on a computer that has the Edge Transport server role installed.


add-attachmentfilterentry -Name <String> -Type <ContentType | FileName> [-Confirm [<SwitchParameter>]] [-DomainController <Fqdn>] [-WhatIf [<SwitchParameter>]]

The Attachment Filter agent can block attachments from entering your Microsoft Exchange Server 2010 organization based on the content type and the file name of the attachment. You can use the Add-AttachmentFilterEntry cmdlet to add file names or MIME content types to the list of attachments that are filtered.

The configuration of the Attachment Filter agent determines how attachments are processed. For more information about how to configure the Attachment Filter agent, see Set-AttachmentFilterListConfig.

You need to be assigned permissions before you can run this cmdlet. Although all parameters for this cmdlet are listed in this topic, you may not have access to some parameters if they're not included in the permissions assigned to you. To see what permissions you need, see the "Anti-spam features" entry in the Transport Permissions topic.

 

Parameter Required Type Description

Name

Required

System.String

The Name parameter specifies the MIME content type or file name of the attachment. If the Type parameter is set to FileName, the Name parameter can take any exact file name, such as BadFile.exe, or file name extension, such as *.exe. If the Type parameter is set to ContentType, the Name parameter can take any valid MIME content type.

Type

Required

Microsoft.Exchange.Data.Directory.SystemConfiguration.AttachmentType

The Type parameter specifies what type of attachment the attachment filter entry blocks. Valid values are ContentType and FileName:

  • ContentType   This value matches the attachment filter entry against the MIME content type specified in the Name parameter.
  • FileName   This value matches the attachment filter entry against the simple file name specified in the Name parameter.

Confirm

Optional

System.Management.Automation.SwitchParameter

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.

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. The DomainController parameter isn't supported on the Edge Transport server role. The Edge Transport server role writes only to the Active Directory Lightweight Directory Services (AD LDS) instance.

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.
