Using Exchange ActiveSync

Microsoft Exchange is, for better or worse, the 800-pound gorilla of corporate email; and its mobile protocol, Exchange ActiveSync (EAS), is the way you connect mobile devices to Exchange. However, a while ago, Microsoft did something quite brilliant with EAS: they decoupled it from Exchange. So, it still has the name, but you can use it with servers that have nothing to do with Exchange, such as servers from Google, Kerio, Zimbra, Atmail, and others.

Exchange ActiveSync, name aside, is a boon to iOS devices and the like because—rather than configuring your email server and your calendar server and your contact server separately—you just set up EAS and you’re done. Exchange ActiveSync also allows handy things for IT folk such as the remote wipe of a device without signing up each and every device for “Find my iPad/iPhone.” In Exchange ActiveSync settings (Figure 4.9), you configure Exchange ActiveSync accounts on your iOS devices.

As with email, you’ll find the ”normal” fields here, such as Account Name, the server name, Use SSL (YES), and so on. A few fields, however, may appear a bit odd to the uninitiated. First of these is the Domain field. If you are on a Windows network using an Exchange Server, the domain is usually your Windows domain. If you’re using a server such as Gmail, or Kerio Connect (that is, something other than an actual Microsoft Exchange server), you can leave this field blank.

The other strange fields are the authentication credential fields. These are used with certificates that validate the server to the client. This may seem odd, but it is a good way to avoid accidental connection to a rogue Exchange server that happens to have the same DNS address as the desired server. As with email settings, leave the User, Email, and Password fields blank unless you specifically want to fill them in for each user.
