WebDav And Exchange2007 HTTP1.1 404 Ressource not Found! - calendar

Question

i have Exchange2007. and
i am using the url:
"https://exchange2007.exchange.server.com/Exchange/username/calendar";
'calendar', or 'mailbox'( in your language! example, "boite de reception" in french or "calendário" in portuguese)
with that url that i'm using i can list my ressources, but can't send a mail or write an appointement! why?!?
See that i get a response of the server 207multistatus and ok, but the return a
HTTP/1.1 404 Resource Not Found
i wish a 201 created!!! (for my appointement)
someone have better ideia ?
thx.

Answer 1

I don't know anything about Exchange, but here are two WebDAV related comments.
1) Your property "mapi" in the namespace "xmlns" looks fishy. Not even Microsoft comes up with a namespace name that bad (I hope).
2) In the second server response, you are getting a status of 200 OK for most properties, except for getcontenttype (which is indeed 404).
Other than that: are you sure you it's the right thing to PROPPATCH against a calendar URL to do what you want?
