I'm trying to exclude XML attachment files from being blocked when using Outlook Web Access. I've made the changes in the reegistry and restarted WWW service but to no avail. Any ideas on why it's still not working?

Which version of Exchange do you have? Which changes did you make to the registry?Outlook Web Access For PDA , OWA For WAP www.owa-pda.com email a@t leederbyshire d.0.t c.0.m

We're running 2003 Ent. I exclude the XML extention in the Level2FileTypes.

Hi,If you have front-end and back-end, then please modify the registry from back-end. 1. Click Start and click Run. 2. Type "regedit" (without quotation marks) and press Enter. 3. Navigate to the [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\MSExchangeWEB\OWA] key. 4. In the right pane, open the Level2MIMETypes value and remove "application/octet-stream" from it. 5. Open the KnownContentTypes value and add "application/octet-stream" to it. 6. Open the KnownContentTypes value and add "application/xml" to it. 7. Open the Level1MIMETypes value and remove "text/xml" from it. 8. Open the Level2MIMETypes value and remove "text/xml" from it.Besides, please apply the last update for Exchange 2003 sp2.Regards,Xiu

Thanks!My bad, I have all the latest patches including SP2 installed.
