Announcing Exchange ActiveSync version 16.1

Thursday, October 19th 2017

Microsoft Exchange has just announced support for EAS Protocol version 16.1 on their blog.

They have introduced three new major capabilities

  1. Improved Keyword Search – Get quicker, more relevant results when searching your inbox. Clients can now perform Keyword Query Language searches (from, to, subject, etc.) by using the new Find command.
  2. Propose New Time – Users have asked for the ability to propose a new time for a meeting while on the go, and we have added full support for new time proposals in EAS 16.1.
  3. Account-Only Remote Wipe – Administrators can now request clients using EAS 16.1 to wipe only Exchange data from a user’s device.

Customers with their mailbox in Office 365 can take advantage of these new features when their favorite EAS client is updated.

How do you know your mailbox is supported with the new EAS Protocol?

As an end user, how can you tell if your mailbox is enabled for EAS version 16.1? The simplest way is to run an “Exchange ActiveSync” test at https://testconnectivity.microsoft.com and look for version 16.1 listed as one of the supported protocol versions (MS-ASProtocolVersions header in the OPTIONS command response) in the test results. Note that you need a valid Office 365 email address and password in order to run that test, and the results are specific to that mailbox only (not the entire tenant).

How to Check EAS 16.1 on you Mobile Device? 

In my case I’m using iPhone 6.0, and the app below shows that these capabilities are available.

Office 365

 

Outlook APP

If you only OWA APP for Exchange is capable of doing these new feature. Outlook App and iOS default Exchange and Outlook can’t perform these features. I believe #Apple will have to support it. But i wonder why only one OWA APP is supporting EAS 16.1 and why not Outlook APP.

In my opinion it would have been  perfect if it supports the native client on iOS which dominate most of the mobile market. I’m not sure about Windows Phone and Android Phones. I believe Apple will get it fixed while I still have to hear from someone if these new capabilities are possible on Windows Phone.
