New-InboxRule -MoveToFolder cant find folder

Hi there,

I was already looking to the other similar issues here about -MoveToFolder but non of the solutions works for me with Exchange2013.

Goal: Provisioning a Rule which checks the header and moves mails to a folder.

Manually I can achieve that by ECP without any problem.

Now I used

$userName = john.doe
$dest = 'archiv'+$userName

New-InboxRule $userName -MoveToFolder $dest -HeaderContainsWords $userName -StopProcessingRules $true

Getting the error:

Postfachordner "archiv:\john.doe" kann nicht gefunden werden. Stellen Sie sicher, dass der Name richtig
eingegeben wurde. Ursache: Der Vorgang konnte nicht ausgeführt werden, weil 'archiv:\john.doe' nicht
gefunden wurde.

(saying: that the mailboxfolder could not be found.)

• The folder is existing definitely!
• Get-MailboxFolder -recurse by the archiv-user himself is working!
  

[PS] C:\Windows\system32>get-mailboxfolder -recurse

• I tried not using variables but typing the values
• I tried already get-mailbox "archiv" | new-... with $_.Alias variable and $($_.Alias) variable
• I tried it by a user of the group "enterprise administrators" (who have full access on the mailbox)
• I tried it by the archiv user itself (because I read that you can use get-mailboxfolder only on your own mailbox and assumed it might be a problem in that direction...
  

Always the same result...I am going mad here!

Please, anybody with some ideas?
