Hello,

I am trying to get this working with a Yahoo calendar but I get an error message when trying to test settings. Error message "An error occurred while sending the request. the server committed a protocol violation, Section=ResponseHeader Detail=CR must be followed by LF". Should this work with Yahoo calendars? How can I fix this error message?

Thanks.

The server sends invalid headers. Enable the commented out option useUnsafeHeaderparsing in the app config file, see Debugging and more config options above.
