Read delegates with WebDav

Hello,

I have a big problem. 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.
I cannot use CDO, or others because the application must connect remote to more servers so I have to use 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. There is only one example on http://blogs.msdn.com/webdav_101/arc...av-sample.aspx but it does not work. This sample returns only a few informations about the mails from mailbox, but nothing about delegates.
I also tried more queries from WebDav reference, like DAV:acl, or DAV:read-acl, but nothing seems to work.
Does anybody know how can I read the delegates and their rights from Exchange 2003 with WebDav ?

Thanks and have a nice day.

WebDAV .NET for Exchange ( http://www.independentsoft.de/webdavex ) can read and set users permissions. We have used the API to read permissions on folders.

Maybe this could be solution for you too.
