![]() Managing Exchange Active. Sync Policies in Exchange 2. Once upon a time, the only way to get your email on a mobile device was to use IMAP or POP (or Research in Motion's Black. Berry devices, but I'm going to pretend like those don't exist because soon they won't). Either choice was widely - - and correctly - - perceived as a bad deal. Neither protocol works especially well for mobile devices because each depends on connection- based polling. Microsoft surveyed this state of affairs and decided to attack it by developing a protocol and server application to provide direct, integrated mobile- device access for Exchange Server. That product, Mobile Information Server, was eventually integrated into Exchange; its protocol, Exchange Active. Sync (EAS), is now the de facto market leader for mobile email and calendaring. Even Microsoft's staunchest competitors, including Google and IBM, have adopted EAS as the basis of mobile- device access for their own email server products. EAS is making inroads on the desktop, too, now that the Windows 8 Mail application and Microsoft Outlook 2. It's too early to sound the death knell for Messaging API (MAPI), but we can envision a future in which EAS is the primary protocol used for Exchange synchronization. There are four points of interest to us: The EAS protocol defines how clients and Exchange talk to each other. The protocol defines how clients can synchronize data with, and download device policies from, Exchange. ActiveSync is a mobile data synchronization app developed by Microsoft, originally released in 1996. It synchronizes data with handheld devices and desktop computers. ActiveSync is the latest software release for synchronizing Windows Mobile-based devices with Windows XP. Microsoft ActiveSync provides a great synchronization. ![]() Microsoft has released the EAS protocol specifications so that, in theory, anyone can release a completely functional EAS client just by reading the protocol docs and writing a client that follows them. Different versions of Exchange implement different EAS versions: Exchange 2. Service Pack 1 (SP1) implements EAS 1. Exchange 2. 01. 3, although this might change when the final product is released.

Whenever user connect a Windows Mobile device to Windows Vista Windows Mobile Device Center (WMDC) via a USB cable, WMDC fails to connect to the Pocket PC (PPC) Phone. Microsoft ActiveSync 4.5 is the latest sync software release for Windows Mobile-powered devices. ActiveSync provides a great synchronization experience with Windows.

Global Address List (GAL) photos. Depending on the feature, you might or might not be able to enable or disable it through EAS policy settings. Clients are free to implement whichever parts of the protocol and features they want. You can't change which features clients support unless you install a different client application, something that isn't always possible. Microsoft and Apple ship EAS clients on their mobile devices; some Android device vendors do too, whereas others require the user to download an app such as Touch. Down or Road. Sync. That's where we get to control which devices and users are allowed to use EAS and what they can do with it when connected. You don't need to do anything to let users sync their devices - - which might or might not be what you want. There are two competing schools of thought when it comes to EAS access. Microsoft Introduces Outlook.com, New Email Service with Metro UI. We all know that Microsoft is upgrading all its services and products to match with Windows 8 Metro UI. From Microsoft: Synchronize your Windows Mobile-based device with a Windows powered desktop PC. Microsoft ActiveSync 4.5 is the latest sync software release for. Some administrators prefer to leave access open to everyone, restricting only a subset of users (e. EAS access. Others prefer to turn off access for all users, and then re- enable it for selected users only. Both approaches are easy to implement; they just require a slightly different approach. First, you can enable or disable EAS on individual Client Access servers. This type of restriction is the broadest option: A Client Access server that has EAS disabled won't accept EAS connections, even from users who are otherwise authorized. Think of it as having a coupon for free ice cream and then presenting it at your local car wash. EAS depends on having a properly configured virtual directory set up in Microsoft IIS on the Client Access server. So to disable EAS, merely go into IIS Manager on the Client Access server, right- click the MSExchange. Sync. App. Pool object, and choose the Stop command. To turn EAS back on, right- click the stopped pool and choose the Start command. The Active. Sync. Enabled flag is what makes the magic happen. You can combine Set- CASMailbox with whichever other Exchange Management Shell (EMS) cmdlets you want. Of course, if you'd rather, you can use the Exchange Management Console (EMC) instead: Just open the target mailbox's properties and use the appropriate controls on the Mailbox Features tab. This is generally the most robust means of control because the EAS policy mechanism gives you the most control over what the devices - - and thus the users - - can do. If you don't explicitly assign a policy to a user, the default policy is applied instead. The Microsoft article . Think of the policy key as a GUID or MAC address; it's a unique key that indicates one specific policy. If the device and server keys don't match, the device is required to request the most recent policy and then apply it. The process of applying a policy to the device is known as provisioning. If the user declines the policy, the server might or might not allow the device to continue to sync to it; the exact behavior depends on whether the default policy on the server allows non- provisioned devices. ![]() The - Active. Sync. Mailbox. Policy switch for Set- CASMailbox controls which policy is assigned to a given mailbox. You can assign a policy by specifying the policy as an argument to this switch. The simplest way to do so is by calling Get- Active. Sync. Mailbox. Policy with the name of the policy you want, as in this example: Set- CASMailbox id paul@robichaux. Active. Sync. Mailbox. Policy (Get- Active. Sync. Mailbox. Policy . Doing so causes the user to get the default policy. There's no way to have a user who doesn't have any policy at all defined. The trick is to remember that not every device will implement every policy setting, and that devices sometimes lie about which policy settings they actually implement. For simplicity, I'll discuss the EAS interface as it appears in EMC. Most organizations that allow mobile- device access require the use of a password. The settings on this tab include the following: Require password - - When the Require password check box is selected, the EAS policy forces the device to require a password. None of the other password options are active when this check box is cleared. If you select this setting without changing any of the other settings, the policy requires a simple 4- digit PIN. The biggest drawback to this requirement is that the on- screen keyboard that the device shows for password entry is easiest to see and use when it contains only numbers. Requiring alphabetic characters means that the device must display its full alphanumeric keyboard, making password entry a little more difficult. Character sets include lowercase letters, uppercase letters, symbols, and numbers. Setting this value to 2, for example, requires that the user pick a password that includes characters from at least two of those four sets. The default value of 1 allows users to specify all- numeric passwords. Exchange administrators can also use the EMC to look up recovery passwords. Windows Phone, Apple i. OS, and most Android clients don't support this setting, which is too bad. It's a useful capability. This is one area in which client software - - Apple's in particular - - has been caught failing to apply device encryption, but it seems that all the major client vendors now properly handle this setting. In EAS, we get the option to force a device erasure after a user enters the wrong password a specified number of times. On most clients, this setting is a floor. That is, if you set this value to 1. This is a tricky setting: Users hate forced PIN changes, so enabling this setting is likely to generate some discontent, especially because users seem to be less likely to write down their PINs in the way that they might write down a complex AD password. However, because there's no way to expire the device passwords as you can for AD passwords, this capability isn't terribly useful. You can limit the number of days worth of calendar items or email that can be synced to the device, although most mobile clients have better controls for selecting how much email is synchronized and from which folders. The two most interesting controls on this tab are the Allow Direct Push when roaming check box, which controls whether devices that are roaming away from their normal cellular carrier network are allowed to use push email, and the Allow attachments to be downloaded to device check box, which gives you a way to keep users from downloading potentially sensitive attachments. Even low- end devices now usually have high- resolution cameras, Bluetooth audio streaming, and other features that once were reserved for high- end devices. Not every organization wants all these features to be available to users. Some customers, such as parts of the US federal government, solve the problem by buying devices that don't have the unwanted features; you can actually buy modern smartphones from which the camera has been removed. More often, though, organizations either tell users not to do certain things (e. EAS provides a means for you to define a policy that blocks certain device features from working . Many devices don't, either because the policy setting doesn't make sense (such as enabling the Allow infrared setting on i. OS devices, which don't have infrared .
