Set-SystemMessage
This cmdlet is available only in on-premises Exchange.
Use the Set-SystemMessage cmdlet to modify custom system messages. System messages are delivery status notifications (also known as DSNs, non-delivery reports, NDRs or bounce messages) and quota messages.
For information about the parameter sets in the Syntax section below, see Exchange cmdlet syntax.

[-Original]
[-Text <String>]
[-WhatIf]
[<CommonParameters>] Description
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
Set-SystemMessage En\Internal\5.3.5 -Text "The recipient email system can't process this email message. Please contact your system administrator for more information."This example modifies the text of the custom English system message for the enhanced status code 5.3.5 for internal senders.
Example 2
Set-SystemMessage En\WarningMailbox -Text "Your mailbox has exceeded the warning limit specified by your email administrator. Please reduce the size of your mailbox."This example modifies the text of the custom English WarningMailbox quota message.
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.

| Default value: | None |
| Required: | False |
| Accept pipeline input: | False |
| Accept wildcard characters: | False |
| Applies to: | Exchange Server 2010, Exchange Server 2013, Exchange Server 2016, Exchange Server 2019 |
-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.
| Type: | Fqdn |
| Position: | Named |
| Default value: | None |
| Required: | False |
| 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 custom system message that you want to modify. You can use any value that uniquely identifies the system message. For example:
- Identity
- Distinguished name (DN)
- GUID
The identity value of a system message uses one of these formats:
- System messages for enhanced status codes:
Language\<Internal | External>\DSNCode. For example,En\Internal\5.1.2orJa\External\5.1.2. - System messages for quotas:
Language\QuotaMessageType. For example,En\ProhibitSendReceiveMailbox.
<Language>: For the list of supported language codes, see Supported languages for NDRs.
<DSNCode>: Valid values are 4.x.y or 5.x.y where x and y are one to three digit numbers. To see the enhanced system codes that are currently used by custom system messages, run the command Get-SystemMessage. To generate a list of default enhanced status codes that are used by Exchange, run this command: Get-SystemMessage -Original | Select-Object -Property Identity,DsnCode,Language,Text | ConvertTo-Html | Set-Content -Path "C:\My Documents\Default DSNs.html".
<QuotaMessageType>: Valid value are:
Mailbox size quotas:

- WarningMailboxMessagesPerFolderCount: A mailbox exceeds its MailboxMessagesPerFolderCountWarningQuota limit when it has a MailboxMessagesPerFolderCountReceiveQuota limit configured.
- WarningMailboxMessagesPerFolderUnlimitedCount: A mailbox exceeds its MailboxMessagesPerFolderCountWarningQuota limit when it doesn't have a MailboxMessagesPerFolderCountReceiveQuota limit configured.
Maximum number of subfolders in a mailbox folder:
- ProhibitReceiveFolderHierarchyChildrenCountCount: A mailbox exceeds its FolderHierarchyChildrenCountReceiveQuota limit.

Maximum number of levels (depth) in a mailbox folder:
- ProhibitReceiveFolderHierarchyDepth: A mailbox exceeds its FolderHierarchyDepthWarningQuota limit.
- WarningFolderHierarchyDepth: A mailbox exceeds its FolderHierarchyDepthWarningQuota limit when it has a FolderHierarchyDepthReceiveQuota limit configured.

-Original
The Original switch specifies whether to stop using the custom system message and start using the default system message. You don't need to specify a value with this switch.
This switch is useful when you want to preserve the custom system message without using it.
This switch only works on custom system messages for default (not new) enhanced status code values.
| Type: | SwitchParameter |
| Position: | Named |
| Default value: | None |
| Required: | False |

| Applies to: | Exchange Server 2010, Exchange Server 2013, Exchange Server 2016, Exchange Server 2019 |
-Text
The Text parameter specifies the text in the custom system message. The text should explain why the system message was sent and any actions that the user should take.
This parameter can contain text and HTML tags. The maximum length is 512 characters (which includes all text and HTML tags).
The following HTML tags are available:
<B>and</B>(bold)<EM>and</EM>(italic)<BR>(line break)<P>and</P>(paragraph)<A HREF="url">and</A>(hyperlink). Note: You need to use single quotation marks (not double quotation marks) around the complete text string if you use this tag. Otherwise, you'll receive an error (because of the double quotation marks in the tag).
Use the following escape codes for these special characters:
<for <>for >"for "&for &
Here's an example value for this parameter that uses HTML tags and special characters:
'You tried to send a message to a <B>disabled</B> mailbox. Please visit <A HREF="https://it.contoso.com">Internal Support</A> or contact "InfoSec" for more information.'
