How can I deactivate the display of fax formulars in Microsoft Outlook?

How can the display of the fax formular for incoming fax messages sent to users of the Outlook client be deactivated? 

This is done directly on the XPhone server under UM > FAX > GENERAL in the "Advanced Settings"

Add the parameter "Fax2Mail\NoFaxHeaders". Add trough a semicolon seperated receiving email addresses as the value for which the fax formular should not be loaded in Microsoft Outlook. If that should be the case for every receiver, set * (star) as the value.

After the settings have been set and saved the UM services have to be restarted under UM > SERVICES.
