Notifications and Syncing Exchange/Office-365 Calendars

Question

I'm working on an application (server-side) that requires syncing calendar events.

The application is intended to work with both Google Calendar and Microsoft Exchange calendar services. I already have the Google calendar syncing in place thanks to their use of web-hook notifications when a resource changes, but I'm having trouble figuring out what method to use with Microsoft's service.

All I've been able to find when searching for a Microsoft solution has been related to EWS. Does the Office 365 calendar API provide any sort of notification mechanism? Am I missing some link/relation between O365 and EWS?

Thanks!

Answer 1

We are working on offering webhooks and sync for Office 365 Mail, Calendar and Contact REST APIs, especially for Calendar. Stay tuned.

[UPDATE] You can use Exchange Web Services in the interim. Take a look at SyncFolderItems, SyncFolderHierarchy, and Notifications. In the Notifications doc, you need to look at the info for Push Notifications.

Answer 2

If you are using O365, you will likely want Streaming Notifications as opposed to Push Notifications.
