SYMPTOMS

In an Exchange Server 2010 environment, you cannot forward a signed S/MIME message by using forwarding rules in Outlook Web App through Exchange Control Panel (ECP). Additionally, when you try to forward a signed S/MIME message, you receive the following non-delivery report (NDR):
Error Message:
------------------

Delivery has failed to these recipients or groups:
 
<john@contoso.com>
The e-mail system had a problem processing this message. Exchange will not try to redeliver this message for you. 
 
Diagnostic information for administrators:
 
Generating server: server.contoso.com<john@contoso.com>
#550 5.6.0 M2MCVT.StorageError; storage error in content conversion ##

RESOLUTION

This hotfix is scheduled to be included in Exchange Server 2010 Service Pack 1 (SP1).

MORE INFORMATION

In Exchange Server 2010 you can forward a signed S/MIME message in Microsoft Office Outlook or in Outlook Web App by using one of the following methods:
  • Forward a signed S/MIME message by using forwarding rules through ECP.
  • Forward a signed S/MIME message as usual.
  • Forward a signed S/MIME message as an attachment.

Currently, only the third method works. Therefore, we recommend that you forward a signed S/MIME message as an attachment in Microsoft Office Outlook or in Outlook Web App.

STATUS

Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section.
