SYMPTOMS
If you use Microsoft Outlook Web Access (OWA) with Internet Explorer to view your Exchange 2003 Inbox, the Inbox opens and all the icons appear, but no messages are listed. If you try to view public folders, the screen is blank.

If you use OWA with Netscape Navigator to view your Inbox and your public folders, all your messages are listed. You determine that there are no network devices (firewalls or routers, for example) that are blocking communication between your client and the OWA Web server.



CAUSE
This issue may occur if the URLScan tool is installed on the OWA Web server. The default configuration of URLScan assumes that the Web server is serving static content only. OWA components use Web Distributed Authoring and Versioning (WebDAV) and other HTTP verbs that are not permitted by the default URLScan configuration. This default configuration prevents the correct display of the Inbox and the public folders.



RESOLUTION
To resolve this issue, edit the Urlscan.ini file to modify the URLScan settings to permit additional WebDAV and HTTP verbs.
