Hi,
I try to create a calender-item in the personal calendar folder from
an ASP.NET application using XML-HTTP Request (WebDAV).
System: Windows 2003 SP1, Exchange 2003 SP1
Configuration IIS: Default Web Site stopped, OWA running on a second
virtual site, my application is running on a third virtual site.
OWA is configured for Integrated Windows Authentication only, my
application the very same. The application uses impersonate=tru e
without a userName.
The problem:
Some times access succeeds. Some times access fails with exception
501 - not implemented. The exception occurs during the attempt to
open a request stream (GetRequestStre am property of HTTPRequest
object) to the private calendar folder.
Post your code. 501 usually means that a particular HTTP method (e.g.
PUT or DELETE) isn't implemented by the server.
Cheers,
