I use Windows 7 and I'm trying to open zimbra account folder using Webdav.

I've been reading this link:
WebDAV - Zimbra :: Wiki

and trying to configure webdav by mapping the following adresses:

\\myserver.domain@80\DavWWWRoot\dav\username
\\myserver.domain\DavWWWRoot\dav\username

But none of then are working... what am I doing wrong?
