OWA on Exchange 2003 gets "unknown error 400" when open up public folders

Has anybody seen this error before? (Please see the attached pic) This only happens when you try to open Public Folders in OWA. As you may know public folders in OWA opens in a separated window different from your emails, contacts& etc.

This happens in our LAN environment, to all users including admins but only in IE. I guess it might have something to do with WEBDAV extension but not an expert for that. For end point protection we have Trend Micro Officescan on the workstations. Any help is appreciated.

are you hosting a replica of the public folders on your OWA machine?

does it work in Firefox?

Are you seeing any other errors in the application logs?

Yes we have a replica hosted on the machine. The OWA works in Firefox because it connects in basic mode (without WebDav extension). And no errors in Application logs.

and is this happening internally? externally? or both?  Running a proxy server? and, if so, are you by-passing it for internal addresses?

You might be having issues with your firewall not passing the http-webdav-extension correctly

We are running IE7 and I've tried previous versions but no luck. The error happens internally and the webdav extension passed through for the initial OWA page (the first page when you logged on), all my mailboxes are available and accessible. However, we are using Trend Micro Officescan 8.0 and ScanMail on the exchange backend servers. I tried to do some research on the Trend Micro side but no luck. And Ive also tried to open OWA on the front end exchange and still got the same error. So& unless anybody got a better idea whats going on, Im not sure it is the firewall.

on your IE settings, have you defined the internal addresses that the proxy shouldn't be used to access?

Yes, "Bypass proxy server for local addresses" is configured through GPO.

I tried it on a clean image VM, no GPO, no Antivirus, and still got the same issue.
