NOTE: These procedures only apply if you have installed Outlook with the Corporate Workgroup/Other option. This option allows you to use Messaging Application Programming Interface (MAPI) services. To determine your installation type, on the Help Menu click About Microsoft Outlook. In About Microsoft Outlook you should see "Corporate" if you have the Corporate Workgroup installation.



SYMPTOMS
If you use Microsoft Outlook with a Microsoft Exchange Server mail system, you may inadvertently forward a message that other Outlook users cannot open. This occurs when the sender has the Microsoft Exchange message security options enabled and the recipient does not.



CAUSE
With Outlook, when you reply or forward an e-mail message, your reply or forwarded message retains the same security as the original message. If the original message was sealed (encoded), your reply or forward remains sealed. Outlook sets the security to match the original message. This behavior helps prevent someone from inadvertently decreasing the security of an ongoing e-mail thread.



RESOLUTION
If you want the reply message to have a different security than the original, on the message toolbar click to turn off the Seal Message or Digitally Sign Message option (whichever is pressed) before clicking Send. This turns off the current security setting.

NOTE: If you do not have the Digitally Sign Message or Seal Message buttons on the message toolbar, then the message you have opened is not signed or sealed. If you do not have these buttons when you compose a new mail message, you are not set up to use these features and cannot open a sealed message.
