Exchange 2010: Moving Messages to Another Working Queue on another CAS Server

One of my CAS Hub servers was acting up and started queuing email. I needed to move the message to another working server while I needed time to troubleshoot what was causing the queuing.

This is what I had to do.

On the non working server:

• Create a Folder on C: called MailsExport
• Open Exchange Management Shell and type the following:

$array = @(Get-Message -Queue "QueueName" -ResultSize unlimited)

$array | ForEach-Object {$i++;Export-Message $_.Identity | AssembleMessage -Path ("c:\MailsExport\"+ $i +".eml")}

• Mail should start exporting.
• Once completed Move the *.eml files to the “Exchange Server\V14\TransportRoles\Pickup” folder on the working server.
• The new server should immediately start processing the messages.
