Description

NDRs are issued to the senders of email messages that haven't reached their intended recipients. Quota messages are issued to users whose mailboxes or public folders have reached the specific warning, prohibit send, or prohibit receive quotas. Custom NDRs and quota messages replace the default messages that are included with Exchange.

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

New-SystemMessage -DsnCode 5.3.5 -Language en -Internal $false -Text "The recipient email system can't process this email message. Please contact your system administrator for more information."

This example creates a custom English NDR for the enhanced status code 5.3.5 for external senders.

Example 2

New-SystemMessage -QuotaMessageType WarningMailbox -Language en -Text "Your mailbox has exceeded the warning limit specified by your email administrator. Please reduce the size of your mailbox."

This example creates a custom English quota message for mailboxes that exceed their issue warning quota.

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.

-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.

You need to use this parameter with the DsnCode or QuotaMessageType parameters.

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:

  • <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:

  • &lt; for <
  • &gt; for >
  • &quot; for "
  • &amp; for &

Here's an example value for this parameter that uses HTML tags and special characters:
