This cmdlet is available only in the cloud-based service.

Use the Get-QuarantineMessageHeader cmdlet to view the message header of a quarantined message. The cmdlet will fail if the specified message is not in quarantine.

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

Get-QuarantineMessageHeader -Identity <QuarantineMessageIdentity>

The following example displays the message header for the specified message that's in quarantine. The Identity value shown is an example, and needs to be replaced by an identity provided by the Get-QuarantineMessage cmdlet.

Get-QuarantineMessageHeader 65ab8c7d-dcd3-4067-7c60-08d116c001c3\8b677327-0ef3-166b-e108-ff6cb380d191

The following example passes the identity of the first message returned by Get-QuarantineMessage to Get-QuarantineMessageHeader.

$qMessages = Get-QuarantineMessage
Get-QuarantineMessageHeader $qMessages[0].Identity

Standard SMTP message header syntax is described in RFC 2822. This cmdlet displays the message header exactly as it appears in the message. Individual header fields are not unfolded.
