Mobile phones that are enabled for Microsoft Exchange ActiveSync let users access most of their Microsoft Exchange mailbox data any time, anywhere. There are many different devices enabled for Exchange ActiveSync. These include Windows Mobile phones, Nokia mobile phones, and Palm mobile phones. This topic provides an overview of these mobile phones.
Although there are several non-phone devices that support Exchange ActiveSync, in most Exchange ActiveSync documentation, these devices are referred to as mobile phones. Unless the feature or features we're discussing require a cellular telephone signal, such as SMS message notification, the term mobile phone means both mobile phone and mobile device.
Exchange ActiveSync is a communications protocol that enables mobile access, over the air, to e-mail messages, scheduling data, contacts, and tasks. Exchange ActiveSync is available on Windows Mobile phones and third-party phones that are enabled for Exchange ActiveSync.
Exchange ActiveSync offers Direct Push technology. Direct Push uses an encrypted HTTPS connection that's established and maintained between the phone and the server to push new e-mail messages and other Exchange data to the phone.
To use Direct Push with Microsoft Exchange Server 2010, your users must have a Windows Mobile phone or a phone with another mobile operating system that's designed to support Direct Push.
Exchange ActiveSync Features
Exchange ActiveSync provides access to many different features. These features enable you to enforce security policies on mobile phones. By using Exchange 2010, you can configure multiple Exchange ActiveSync policies and control which phones can synchronize with your Exchange server. Exchange ActiveSync enables you to send a remote device wipe command that wipes all data from a mobile phone in case that phone is lost or stolen. Users can also initiate a remote device wipe from Outlook Web App.
Exchange ActiveSync allows users to generate a recovery password. This recovery password is saved on the mobile phone and is used when a user forgets their password. The user generates the recovery password at the same time that they generate the device password or PIN. This recovery password can be used to unlock the phone. Immediately after this recovery password is used, the user will be required to create a new PIN.

Windows Phone 7 synchronization
If you're configuring a Windows Phone 7 mobile phone to synchronize with an Exchange mailbox using Exchange ActiveSync, synchronization will fail under the following two simultaneous conditions:
- If the AllowNonProvisionableDevices property of the
Exchange ActiveSync mailbox policy is set to False.
- If any policy properties that aren't included in the following
list are configured for the Exchange ActiveSync mailbox policy:
If you have Windows Phone 7 mobile phones in your organization, you can set AllowNonProvisionalDevices property to true or you can create a separate Exchange ActiveSync mailbox policy for users with Windows Phone 7 mobile phones. This new Exchange ActiveSync mailbox policy should either have the AllowNonProvisionalDevices property set to true or only have the preceding list of policy properties configured.
