Try the following:
This issue may occur if you publish a Microsoft Exchange Server 2003 OWA site behind Microsoft Internet Security and Acceleration (ISA) Server or Microsoft Forefront Threat Management Gateway, Medium Business Edition. This issue occurs if both the following conditions are true:
To work around this issue, configure the Web publishing rule so that it does not block high-bit characters. To do this, follow these steps:
When you configure HTTP filtering to block high-bit characters, URLs that contain characters from a double-byte character set (DBCS) or URLs that contain Latin 1 characters are blocked. This configuration may affect scenarios such as OWA publishing or Microsoft SharePoint Portal Server publishing. Additionally, this configuration may affect any scenario where a GET request passes a parameter that includes a character from a double-byte character set. You can configure HTTP filtering on a per rule basis for Web publishing rules or for access rules in ISA Server or in Microsoft Forefront Threat Management Gateway, Medium Business Edition. For additional information about HTTP filtering, search on "HTTP filtering" in ISA Server Help or in Microsoft Forefront Threat Management Gateway, Medium Business Edition Help.
Note You may receive the message that is mentioned in the "Symptoms" section if you configure HTTP filtering to reject part of the HTTP request or part of the HTTP response. If you want to permit the request, review and reconfigure the HTTP filtering rule that affects the request.
