Exchange Server Webdav: How to retrieve the unique id of new items created

Question

I am creating the appointments using WebDav in Exchange server 2003 and it is working perfectly fine. I however want to get an handle for the newly created items for future user like setting custom property/deleting etc.

How to get back a unique ID or something for the newly create the appointment? Does the PROPPATCH return any value??

Thanks Shreedhar

When you create new item server returns MultiStatus. Inside MultiStatus response is item's url. Keep this url for later use (to delete/update item).

There is also a library with clean design from Independentsoft which implements WebDAV protocol for Exchange. It also returns item's url when you create new item.
