How to run a PowerShell / ImapX script manually or in Task Scheduler?

Question

I'm running this script in PowerShell ISE and it works great and it downloads the attachments to the folder I've specified.

But if I run it manually in PowerShell using PS C:\tmp> .\pdftofolder.ps1 it doesn't download the attachments and the log says this:

And if I run it through the Task Scheduler (which is the ultimate goal) it just gets stuck. I run it with this command (its ran with highest privileges btw):

Start-Transcript -path C:\tmp\log.txt -append

$dll = 'C:\tmp\ImapX.dll'
[Reflection.Assembly]::LoadFile($dll)

$Username = "[email protected]"
$Password = "foo"

# Initialize the IMAP client
$client = New-Object ImapX.ImapClient

###set the fetching mode to retrieve the part of message you want to retrieve, 
###the less the better
$client.Behavior.MessageFetchMode = "Full"
$client.Host = "mail.foo.com"
$client.Port = 993
$client.UseSsl = $true
$client.Connect()
$client.Login($Username, $Password)

foreach($m in $messages){
    $m.Subject
        foreach($r in $m.Attachments){ 
                Write-Host $m.Attachments
                $r.Download()
                $r.Save('C:\tmp\dl')
                }
       }

Stop-Transcript

What part of running a PowerShell script made after its built in ISE have I missed?

Answer 1

You've skipped

 $messages = $client.Folders.Inbox.Search("ALL", $client.Behavior.MessageFetchMode, 1000)
