I’ve recently been sent hundreds of emails saved as msg files which I needed to extract and save all of the attachments so they could be processed. Opening each message individually in Outlook and saving the attachments would of taken a month of Sundays. So instead I wrote the following powershell script.

param([string]$msgpath = [System.IO.Directory]::GetCurrentDirectory(), [string]$savepath = [System.IO.Directory]::GetCurrentDirectory() )
$outlook = new-object -comobject outlook.application
$msgs = get-childitem $msgpath -filter *.msg

foreach ($msg in $msgs)
{
	
	if ($msg.exists -eq $true) {
	write-host "opening message:" $msg
	$Omsg = $outlook.CreateitemFromTemplate($msgpath+$msg)
	$Omsg.attachments|foreach {
		$_.saveasfile((join-path $savepath $_.filename))
	}
	}
}

The script accepts 2 input parameters msgpath and savepath. msgpath is the path to the saved msg files. savepath is the path to save the attachments to. Both parameters default to the current working directory if they aren’t supplied.
