Suspend-Message

  • Artikel

 

Applies to: Exchange Server 2007 SP1, Exchange Server 2007 SP2, Exchange Server 2007 SP3

Use the Suspend-Message cmdlet to prevent delivery of a particular message in a queue on a computer that has the Hub Transport server role or the Edge Transport server role installed.

Syntax

Suspend-Message -Identity <MessageIdentity> [-Confirm [<SwitchParameter>]] [-WhatIf [<SwitchParameter>]]

Suspend-Message -Filter <String> [-Confirm [<SwitchParameter>]] [-Server <ServerIdParameter>] [-WhatIf [<SwitchParameter>]]

Detailed Description

The Suspend-Message cmdlet prevents delivery of one or more messages that are in a queue on the Hub Transport server or the Edge Transport server. A message that is already in delivery will not be suspended. Delivery will continue and the message status will be PendingSuspend. If the delivery fails, the message will re-enter the queue and it will then be suspended. You cannot suspend a message that is in the Submission queue or in the poison message queue.

A message that is being sent to multiple recipients might be located in multiple queues. If you specify an Identity parameter, the message will be suspended in a single queue if that identity matches only a single message. If the identity matches more than one message, you will receive an error. To suspend a message in more than one queue in a single operation, you must use a filter. You must use an Identity parameter or a Filter parameter. These two parameter sets are mutually exclusive.

You can suspend a message on a remote server by including the server name as part of the Identity parameter or by using the Server parameter with the Filter parameter. If you do not specify a server, the command runs against only the local server.

To run the Suspend-Message cmdlet, the account you use must be delegated the Exchange Server Administrator role and local Administrators group for the target server.

To run the Suspend-Message cmdlet on a computer that has the Edge Transport server role installed, you must log on by using an account that is a member of the local Administrators group on that computer.

Parameters

Parameter Required Type Description

Filter

Required

System.String

The Filter parameter requires an expression that specifies the property value criteria for the messages that you want to suspend. The expression includes a property name that is followed by a comparison operator and value. The following message properties are valid criteria for the Filter parameter:

  • DateReceived   The date that the message was received.

  • ExpirationTime   The time that a message will expire.

  • FromAddress   The Simple Mail Transfer Protocol (SMTP) address of the sender of a message. This value is taken from MAIL FROM: in the message envelope.

  • Identity   An integer that represents a particular message and an optional server and queue identity.

  • InternetMessageId   The value of the MessageID: header field. This property is expressed as a GUID followed by the SMTP address of the sending server, as in this example: 67D7543D6103DC4FBEBA6BC7205DACABA61231@exchange.contoso.com.

  • LastError   A text string of the last error recorded for a message.

  • MessageSourceName   A text string of the name of the component that submitted this message to the queue.

  • Queue   Specifies the identity of the queue that holds the message. Enter the queue identity in the form of Server\destination, where destination is a remote domain, mailbox server, or persistent queue name.

  • RetryCount   The number of times that delivery of a message to a destination was tried.

  • SCL   The spam confidence level (SCL) property specifies the SCL of the message. Valid SCL entries are integers 0 through 9. An empty SCL property value indicates that the message hasn't been processed by the Content Filter agent.

  • Size   The size of a message.

  • SourceIP   The IP address of the external server that submitted the message to the Exchange organization.

  • Status   The current message status. Message status options are Active, Retry, Suspended, PendingSuspend, or PendingRemove.

  • Subject   A text string that represents the e-mail subject. The value is taken from the Subject: header field.

You can specify multiple filter criteria by using the -and comparison operator. Property values that are not expressed as a single integer must be enclosed in quotation marks.

Identity

Required

Microsoft.Exchange.Data.QueueViewer.MessageIdentity

Use the Identity parameter to specify the MessageIdentity integer that represents a particular message and an optional server and queue identity. The syntax for this parameter is as follows:

  • Server\QueueIdentity\MessageIdentity

  • QueueIdentity\MessageIdentity

  • Server\*\MessageIdentity

  • MessageIdentity

Confirm

Optional

System.Management.Automation.SwitchParameter

The Confirm parameter 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 parameter.

Server

Optional

Microsoft.Exchange.Configuration.Tasks.ServerIdParameter

Use the Server parameter to specify the name of the server to connect to by using remote procedure call (RPC) that contains the queues that hold the messages that you want to suspend. Enter the server name as a host name or a fully qualified domain name (FQDN). If this parameter is not used, the local server is queried.

WhatIf

Optional

System.Management.Automation.SwitchParameter

The WhatIf parameter instructs the command to simulate the actions that it would take on the object. By using the WhatIf parameter, 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 parameter.

Example

The following example shows how to prevent delivery of all messages for which the following conditions are true:

  • The messages are sent from the specified sender's SMTP address.

  • The messages are queued on the Hub Transport server or the Edge Transport server on which the command is run.
