[asterisk-users] Calendar Integration Problem

[Bharat Lalcheta]

Hii All,

Thanks for helps. Problem solved. Its due to exchange side authentication
problem. In exchange IIS server ,for EWS site only window authentication
enabled which is not supported by neon library. Just enabled basic
authentication for EWS site on IIS and its working fine now.

Thanks for help..
