[Owncloud] Problems with ownCloud in Windows+IIS and eM Client

[Leon Orator]

Hello,

I installed ownCloud on Windows 7 + IIS. The web application seems to 
work well, but when i try to access the Contact List from a CardDAV 
client -in this case, em Client- i get the following error:

[CalDAV / CardDAV]  MailExceptions.OperationException: Subfolder 
synchronization for folder "testOwn" failed with following error: Not Found

I tried the eM Client with other CardDAV servers (Sogo, Memotoo) and it 
works.

The address I use in eM Client for the CardDAV server is:
http://myowncloud/owncloud/apps/contacts/carddav.php/


This is the web server log:
2011-12-07 18:30:25 127.0.0.1 OPTIONS 
/owncloud/apps/contacts/carddav.php/ - 80 - 127.0.0.1

eM+Client/3.5.12280.0 404 0 123 2

It seems it can't find the proper resource. Could it be an IIS 
configuration problem, maybe related to WebDAV support? Or is someting 
wrong with the ownCloud installation?

And by the way, could you suggest a tool to test the CardDAV server? I 
mean, a desktop application that allows you to send CardDAV commands and 
see the response from the server?


Thank you.
