Some time ago office365 team announced that shared calendars are now synchronized (with some limitations) over EAS. But this applies only to outlook.com and office365 users. So, my questions are:
What are min requirements to get shared calendars synchronization over EAS for hybrid and pure on-premise environments?
Is there any confirmed plans to add it if it is not available now?
The answer is quite critical as my company develops mobile exchange email client and this question is quite hot amoung our customers.
