The body of the e-mail message appears empty when you open an encrypted or a digitally signed e-mail message in Outlook 2003

If you open an encrypted or a digitally signed e-mail message in Microsoft Office Outlook 2003, the body of the e-mail message appears to be empty. This problem occurs when you use Outlook 2003 in Cached Exchange Mode. If you use Outlook 2003 in online mode, the content in the body of the e-mail message appears as expected.

This problem may occur if both of the following conditions are true:

• You use the CryptoEx Outlook security add-in program. This third-party software is made by the Glück & Kanja Group. It is used to encrypt or to digitally sign e-mail messages.
• Outlook 2003 is configured to use Cached Exchange Mode.

When the CryptoEx Outlook security add-in program tries to replace the original encrypted or signed e-mail message body with the decrypted content, the call is unsuccessful, and the e-mail message body appears to be empty.

This problem was first fixed in a hotfix that is now contained in a service pack. If you installed the latest Microsoft Office 2003 service pack, you do not have to install the hotfix.
