When I connect to all mailboxes using PFDAVADMIN to my exchange 2007 server I get a list of all the userse but when I expand any of the users I get the following error
Could not expand http://server.local/exadmin/admin/PGW.LOCAL/mbx/[email protected]/non_ipm_subtree/: The remote server returned an error: (404) Not Found.
I was getting the same problem a while ago, what I did was :
I logged on to my workstation (Windows7) on the same Subnet / Domain as Exchange.
On the connect window for PFDavAdmin, I specified DNS Names for Exchange Server and Global Catalog Server,
Authenticate as Currently Logged on User
It worked straightaway for Public Folders and Mailboxes.
Try that if you haven't already - it will be good if your workstation and your exchange server are on the same domain (ofcourse) and using the same DNS server.
Hope that Helps
