title: Edit all ressource Mailbox settings of all the available ressource mailboxes in Powershell at once
body: <p>Quick introduction to my issue:</p>
  
  <p>Our Resource-Mailboxes show the name of the organizer of the meeting instead of the subject.
  I found following solution to this problem (Powershell Script)</p>
  
  <pre><code>Set-CalendarProcessing -Identity &lt;RESOURCEMAILBOX&gt; -DeleteSubject $False -AddOrganizerToSubject $False 
  </code></pre>
  
  <p>This works perfectly so far BUT... is there a way to set this Option for ALL Resourcemailboxes available?</p>
  
  <p>something like...<code>Set-CalendarProcessing -Identity &lt;*&gt;</code> ... ?</p>
  
  <p>Thank you for your time.
  Cheers
  Denis</p>
