Problem with WEBDAV configuration-need advice

[shk2287]

Hi everybody

I am trying to configure WEBDAV in outlook express but it is not working. It says unable to connect to the server and following is the error message.
Unable to poll for new messages on your HTTP
server. Account: 'WebDAV', Server: '

http://server_name/exchange/user_name',

Protocol: HTTPMail, Server Response: '', Port: 0, Secure(SSL): No, Socket Error: 12029, Error Number: 0x800CCC0E

One thing which I want to bring to the knowledge is that I have configured SSL on my exchange server and to accesss OWA I type address

https://server_name/exchange/username.

OWA works fine. I tried in Outlook express also to put server address as

https://server_name/exchange/user_name

but it keep trying to communicate with the server and never works. Adive highly appreciated. Plz if some have any advice, plz write back at shk2287@yahoo.com.

with best regards

Shakeel
