Dear Team,

I am creating an application using NodeWebkit and javascript for achieving following functionalities:

• Autodicover URL
• Fetching calender items
• Get user availability details
• Fetching contacts
• For streaming notification

Please let me know the recommended way of connecting EWS using javascript. Also, Please let me know is there any javascript API to connect to EWS. Any help would be highly appreciated.

Thanks,

Alka Saini

EWS doesn't support Cross-origin resource sharing (CORS) so building SPA type browser applications that will directly authenticate against an Exchange Mailbox generally won't work (in Office365 and coming Exchange 2016 there is new REST API with CORS support). One workaround is build an intermediary web Service that uses something like the JAVA ews api https://github.com/OfficeDev/ews-java-api and then instrument your requests via the intermediary to your backend 2007 server.

Cheers
Glen
