Suspend-Message

Reference

Module:: ExchangePowerShell

Applies to:: Exchange Server 2010, Exchange Server 2013, Exchange Server 2016, Exchange Server 2019

This cmdlet is available only in on-premises Exchange.

Use the Suspend-Message cmdlet to prevent delivery of a particular message in a queue on a Mailbox server or an Edge Transport server.

For information about the parameter sets in the Syntax section below, see Exchange cmdlet syntax.

Syntax

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

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

Description

A message already in delivery won't 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 can't suspend a message that's in the poison message queue.

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

For instructions on how to resume a suspended message, see Resume-Message.

You need to be assigned permissions before you can run this cmdlet. Although this topic lists all parameters for the cmdlet, you may not have access to some parameters if they're not included in the permissions assigned to you. To find the permissions required to run any cmdlet or parameter in your organization, see Find the permissions required to run any Exchange cmdlet.

Examples

Example 1

Suspend-Message -Server Server1 -Filter "FromAddress -eq '[email protected]'"

This example prevents delivery of all messages for which the following conditions are true:

The messages are sent by the sender [email protected].
The messages are queued on the server Server1.

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.

Applies to:	Exchange Server 2010, Exchange Server 2013, Exchange Server 2016, Exchange Server 2019

-Filter

The Filter parameter specifies one or more messages by using OPATH filter syntax. The OPATH filter includes a message property name followed by a comparison operator and value (for example, "FromAddress -like '*@contoso.com'"). For details about filterable message properties and comparison operators, see Properties of messages in queues and Find queues and messages in queues in the Exchange Management Shell.

You can specify multiple criteria by using the and comparison operator. Property values that aren't expressed as an integer must be enclosed in quotation marks (").

Accept pipeline input:	False
Accept wildcard characters:	False
Applies to:	Exchange Server 2010, Exchange Server 2013, Exchange Server 2016, Exchange Server 2019

-Identity

The Identity parameter specifies the message. Valid input for this parameter uses the syntax Server\Queue\MessageInteger or Queue\MessageInteger or MessageInteger, for example, Mailbox01\contoso.com\5 or 10. For details about message identity, see Message identity.

Type:	MessageIdentity
Position:	1
Default value:	None
Required:	True
Accept pipeline input:	True
Accept wildcard characters:	False
Applies to:	Exchange Server 2010, Exchange Server 2013, Exchange Server 2016, Exchange Server 2019

-Server

The Server parameter specifies the Exchange server where you want to run this command. You can use any value that uniquely identifies the server. For example:

Name
FQDN
Distinguished name (DN)
Exchange Legacy DN

If you don't use this parameter, the command is run on the local server.

You can use the Server parameter and the Filter parameter in the same command. You can't use the Server parameter and the Identity parameter in the same command.

-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.
