    Hello Daniel,

    I am working at one application which have to communicate with Exchange 2003 and to read the delegates and their rights for given user email with WebDav. The names of the delegates for a user email can be read from Active Directory (there is a property "publicDelegates") but the schema of their rights (right to read email,or rights to read/edit calendar, or tasks) is stored in Exchange. I tried a lot of WebDav queries but I did not found nothing to help. Unfortunatelly this sample which I found here does not work. The sample returns a XML string which contains more nodes for every folder from mailbox, like this one:


    – <a:propstat>

     <a:status>HTTP/1.1 404 Resource Not Found</a:status>

    – <a:prop>

     <d:dlmembers />




    – <a:response>

    So in the node <d:dlmembers /> there is nothing even I added few delegates for the mailbox of the user administrator. I also tried with publicDelegates, or public-delegates.  How can I read the delegates and their rights from Exchange 2003 with WebDav ?

    I found nothing about dlmembers property in WebDav reference on Microsoft site.
