Paul is a Microsoft MVP for Office Apps and Services and a Pluralsight author. He works as a consultant, writer, and trainer specializing in Office 365 and Exchange Server. A mechanism exists to allow the client to indicate that it couldn't apply some parts of the policy in either of two ways: The client can indicate that part of the policy is irrelevant (e.g., disabling Bluetooth on a device that doesn't support it) or that the policy couldn't be applied (e.g., requiring device encryption that isn't supported). Beyond this mechanism, the server has no enforcement mechanism to verify that the client is telling the truth. For example, some versions of Apple iOS lie about whether they can enforce device encryption when the EAS policy is set to require it. Therefore, you might create a policy that's honored by only some of the devices that sync with your server, and you won't know unless you keep track of which devices you have and the specific policy features that they do and don't support.If the mailbox receives a new item the server responds to the HTTPS request.

The simplest way to apply a given set of EAS settings is to change the settings of the default policy to match the values that you want.

It’s my understanding that internal clients on the trusted LAN would all use SCP to resolve autodiscover & use the internal url (FQDN of the CAS) and for external clients such as iphones or android autodiscover would be needed on external DNS. Many protocols provide some means of negotiation, whereby the client and server can agree on exactly how their communications should go. EAS isn't one of these protocols. When a device first synchronizes, the server and client negotiate which EAS version they'll use; they agree on the highest version that they both support. This happens when the client sends a provisioning request to the server and the server responds with a temporary synchronization key and a policy. The client should return an indication that it will enforce the server-supplied policy. The client then gets a permanent synchronization key, and there's no further checking or enforcement of what the client says. In an EAS conversation, the Exchange server presents a policy to the client, and the client is expected to honor it.

This name is a little misleading; when most of us think of Exchange rules, we think of things such as Outlook rules or transport rules, which typically contain a condition, an action, and a set of exceptions. EAS ABQ rules specify a device family and a device model. The predefined families include the iPhone, iPad, iPod, Android, and Windows Phone. After a user has synchronized a device that you want to use as the basis for a device access rule, you can create one by performing the following steps: Now that you know how EAS ABQ is implemented, you're probably wondering how you actually set things up to control which devices can connect. You need to worry about only a few scenarios:

All new devices (i.e., those that have never previously tried to sync with a mailbox in the organization) start in the device discovery state. This state is short-lived, though. The longest that a device can stay in this state is 14 minutes (1 minute less than the default EAS heartbeat timeout interval). After that, EAS uses a straightforward algorithm to determine which state to use. This algorithm technically begins with forcing the device to authenticate. (If the device can't authenticate, then it doesn't enter any state because the Client Access server won't talk to it.) After the device authenticates, here's how the algorithm works: Nokia Expands Microsoft Exchange ActiveSync Enabling Device Range.

First, you can use the Set-CASMailbox cmdlet with the -ActiveSyncEnabled parameter to turn off EAS access for the user's mailbox. Of course, if you turn off EAS, the user won't be able to synchronize any device (which might be exactly what you want). As a security measure, many organizations disable EAS for all mailboxes and then enable it only for users who have permission to sync their devices.Please note that you need an Exchange organization administrator role for enabling and disabling Exchange ActiveSync.domain.com, autodiscovery.domain.com, and SRV records were added to dns, all that name in cert too, but automatic detection does not work in mobiles, after tried the mobil left the fields for user, server y domain with: user.domain.com, domain.com and empty.

Exchange Server 2010 Service Pack 2 (SP2) implements EAS version 14.2. However, not every client can say the same. Because so many mobile devices support EAS, you can't assume that any particular device family supports a particular EAS version, or even all the features in that version. Microsoft started a Wiki page to document which specific EAS features various device and OS combinations support. It's a valuable reference because it tells you whether a given device will support an EAS policy or feature that you need. For example, Apple's iOS 5 and Google's Android Ice Cream Sandwich release both support the disable camera EAS setting, but other versions don't.
