SYMPTOMS
In Microsoft Antigen 9.0 for Microsoft Exchange or in Microsoft Antigen 9.0 for SMTP Gateways, you try to use the Add Outbound Disclaimer function to attach a disclaimer message to an outgoing e-mail message. When you do this, the whole e-mail message is unreadable when the e-mail message is delivered to the recipient.



CAUSE
This problem occurs if the disclaimer message includes non-US-ASCII characters. By default, Antigen formats the e-mail message in the basic Internet encoding standard when Antigen adds a disclaimer message. The basic Internet encoding standard is the UTF7 encoding standard. However, many languages include characters that are not included in the UTF7 encoding standard. Therefore, non-US-ASCII characters are not represented correctly after Antigen processes the e-mail message.

By default, Antigen formats the e-mail message in the UTF7 encoding standard even if the original e-mail message from the sender is in a different character set. For example, Antigen does this even if the original e-mail message is in the ISO-8859-1 character set.



RESOLUTION
Warning Serious problems might occur if you modify the registry incorrectly by using Registry Editor or by using another method. These problems might require that you reinstall the operating system. Microsoft cannot guarantee that these problems can be solved. Modify the registry at your own risk.

 Right-click Antigen for Exchange, point to New, and then click DWORD Value. To name the new value, type ForceDisclaimerNonUTF7, and then press ENTER. Right-click ForceDisclaimerNonUTF7, and then click Modify. In the Value data box, type 1, and then click OK.</li></ol>
