Consider the following scenario:
- S/MIME in Outlook Web App (OWA) is enabled in a Microsoft Exchange Server 2010 SP1 environment.
- A sender sends an encrypted or digitally-signed message to a recipient.
- The recipient uses OWA to open the message and tries to print it.
- The printer selection dialog box is displayed. The recipient selects the printer and presses the Print button.
This issue occurs because the encrypted or digitally-signed message is not correctly rendered when S/MIME control is installed.
Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section.
