Transport Rule Actions

Exchange 2010
 

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

Topic Last Modified: 2009-09-22

Transport rule actions instruct the rules agent to take the specified action on messages that match all the predicates in a condition, and don't match any of the exceptions. In Microsoft Exchange Server 2010, both the Hub Transport server and Edge Transport server can apply transport rules to e-mail messages routed by them. Some actions are available on both transport server roles, and some are exclusive to either role.

Each action affects e-mail messages in a unique way. For example, an action can cause an e-mail message to be redirected to another address or to be deleted. Each action consists of the action itself, its action property, and the value of the property.

To assign a value to an action, you must determine the available action property for a specific action. For example, you must use the Address action property together with the RedirectMessage action. (For information about the action properties available for use with Hub Transport servers and Edge Transport servers, see the tables later in this topic.)

Some actions require that you set two or more action properties, because some actions modify specific fields within sections of an e-mail message, such as the message header fields. When you specify an action to modify a message header, one action property specifies the specific header field to modify, and a second action property specifies the new value of the message header. In these cases, you must also specify a value for the second action property, as shown later in this topic in the Additional action property table column in either Actions Available on a Hub Transport Server or Actions Available on an Edge Transport Server, depending on the server role. For example, you can configure an action to modify the X-Test-Message-Source header field to a specific string, such as contoso.com.

You can use either the Exchange Management Console or the Exchange Management Shell to create or modify a transport rule. For relevant procedures, see Transport Rules.

The following table lists the action properties used by transport rules actions on Exchange 2010 Hub Transport or Edge Transport servers.

Action properties for transport rules on a Hub Transport server or an Edge Transport server

Action property Expected format Description

AddedRecipientType

One of the following values:

  • To

  • Cc

  • Bcc

  • Redirect

AddedRecipientType accepts a single value:

  • To, Cc, and Bcc values are self-explanatory and correspond to the addressing fields of e-mail messages.

  • Redirect delivers the message only to the specified recipient. The message isn't delivered to any of the original recipients.

Addresses

  • Edge Transport server   Array of SMTP addresses

  • Hub Transport server   Array of Active Directory mailbox, contact, mail-enabled user, or distribution group objects

On an Edge Transport server, Addresses accepts an array of SMTP addresses that are each enclosed in quotation marks (").

On a Hub Transport server, Addresses accepts an array of mailbox, contact, mail-enabled user, or distribution group objects.

Classification

Single message classification object

Classification accepts a single message classification object. To specify a message classification object, use the Get-MessageClassification cmdlet.

For more information about message classifications, see Understanding Message Classifications.

DisclaimerLocation

One of the following values:

  • Append

  • Prepend

DisclaimerLocation specifies where the disclaimer is inserted into the e-mail message:

  • Append (default) adds the disclaimer at the bottom of the message thread.

  • Prepend puts the disclaimer at the start of the newest e-mail message.

EnhancedStatusCode

Single DSN code of 5.7.1, or any value from 5.7.10 through 5.7.999

EnhancedStatusCode specifies the DSN code and related DSN message to display to the senders of messages rejected by the RejectMessage transport rule action. The DSN message associated with the specified DSN status code is displayed in the user information portion of the NDR displayed to the sender. The specified DSN code must be an existing default DSN code or a customized DSN status code that you can create by using the New-SystemMessage cmdlet.

EventMessage

Single string

EventMessage accepts a single string displayed in an event log, which is added to the application event log on the local computer.

FallbackAction

Single value with the choices of Wrap, Ignore, or Reject

FallbackAction specifies what the transport rule should do if a disclaimer can't be applied to an e-mail message such as when a message is encrypted. The default fallback action is Wrap. Enclose the value in quotation marks ("). The following list shows each fallback action and its description:

  • Wrap   If the disclaimer can't be inserted into the original message, Exchange encloses, or wraps, the original message in a new message envelope. Then the disclaimer is inserted into the new message.

    importantImportant:
    If an original message is wrapped in a new message envelope, subsequent transport rules are applied to the new message envelope, and not to the original message. Therefore, you must configure transport rules with disclaimer actions that wrap original messages in a new message body after you configure other transport rules.
    noteNote:
    If the original message can't be wrapped in a new message envelope, the original message isn't delivered. The sender of the message receives an NDR that explains why the message wasn't delivered.
  • Ignore   If the disclaimer can't be inserted into the original message, Exchange lets the original message continue unmodified. No disclaimer is added.

  • Reject   If the disclaimer can't be inserted into the original message, Exchange doesn't deliver the message. The sender of the message receives an NDR that explains why the message wasn't delivered.

HeaderValue

Single string

HeaderValue accepts a single string that's applied to the header specified by using the MessageHeader action property. Enclose the string in quotation marks (").

MessageHeader

Single string

MessageHeader accepts a string that specifies which MessageHeader to add or modify. The string that's specified by using the HeaderValue action property is inserted into the header that's specified by MessageHeader. Enclose the string in quotation marks (").

Prefix

Single string

Prefix accepts a string that's prepended to the subject of the e-mail message. Enclose the string in quotation marks (").

To prevent the string that's specified with the Prefix transport rule action from being added to the subject every time that a reply to the message encounters the transport rule, add the SubjectContains exception to the transport rule.

The SubjectContains exception should contain the string that you specified with the Prefix transport rule action. If you add the SubjectContains exception to the transport rule, the transport rule doesn't add another instance of the Prefix string to the subject if the Prefix string already appears in the subject.

RejectReason

Single string

RejectReason accepts a string that's used to populate the administrator information portion of the NDR returned to the e-mail sender if an e-mail message is rejected. Enclose the string in quotation marks (").

RMSTemplateIdentity

RMS Template identity

RMSTemplateIdentity accepts an RMS Template identity. You can get a list of RMS templates available on an Active Directory RMS server in the Active Directory forest using the Get-RMSTemplate cmdlet.

SclValue

Single integer

SclValue accepts a single integer from 0 through 9, which is used to configure the SCL of the e-mail message. Enclose the integer in quotation marks (").
