sharing agenda from outlook.com with Ical

Hi,

I hope my English writing is understandable :-)

I'm trying to sync my agenda from my mailacount at outlook.com with Ical.

I can send a mail from the outlook account fot sharing the agenda. I get a link in my mailprogram at the imac were I can accept the invitation for sharing the agenda.

When I click on accept, safari opens the site of outlook.com where I must log in to.

But when I do this (by the way: what should people do when they don't got a outlook.com account???) I get an error site:

Server Error in '/Calendar' Application.

Runtime Error

Description: An application error occurred on the server. The current custom error settings for this application prevent the details of the application error from being viewed remotely (for security reasons). It could, however, be viewed by browsers running on the local server machine.
Details: To enable the details of this specific error message to be viewable on remote machines, please create a <customErrors> tag within a "web.config" configuration file located in the root directory of the current web application. This <customErrors> tag should then have its "mode" attribute set to "Off".

<!-- Web.Config Configuration File -->  <configuration> <system.web> <customErrors mode="Off"/> </system.web> </configuration>

Notes: The current error page you are seeing can be replaced by a custom error page by modifying the "defaultRedirect" attribute of the application's <customErrors> configuration tag to point to a custom error page URL.

<!-- Web.Config Configuration File -->  <configuration> <system.web> <customErrors mode="RemoteOnly" defaultRedirect="mycustompage.htm"/> </system.web> </configuration>

Were does it go wrong?

greeting Sven.
