ActiveSync can push the e-mails directly to your phone (as of version 4.5). Outlook 2013 also has ActiveSync functionality.

It is intended for mobile phones. The main idea is to have the phone recieve the mails without polling the server to check for new mails on intervals, thus saving power and data usage.

No, you are not using the same protocol. ActiveSync is only for mobile devices, not a traditional computer (PC: desktop, laptop). While Outlook 2013 does have built-in support for ActiveSync, you cannot connect to an Exchange server using ActiveSync.

See Activesync/OWA Desktop Client and my answer there for more details, discussion and additional links.

Microsoft and others have many posts about configuring Outlook Anywhere for various version of Exchange. I think 2007 was the first version to do this. I can tell you it can be a bit tedious, and requires some specific things (like valid SSL certificates, not self signed ones).

A Microsoft Exchange account is a work or school email account. The organization that gave you the Exchange email account is running a Microsoft Exchange Server, or is using Microsoft Office 365 which uses Exchange Server to provide email.

What's the name of my Exchange server?

You usually won't need to know the name of your Exchange server. If you do, contact the people who gave you the Exchange email address and ask them for the name of the Exchange server.

When you set up a mobile device, the AutoDiscover feature will find the name of your Exchange server and mailbox, and configure Outlook for you. It uses the domain name in your email address to find the server. Only if Autodiscover fails will you be asked for the name of the Exchange server. At this point, usually something isn't working correctly and you’ll need to contact the people who gave you the email address. They'll tell you the name of your Exchange server and help you set up Outlook.

How do Exchange accounts work?

When you use an Exchange account, your email messages are delivered to and saved in your mailbox on the Exchange server. Your contacts and calendar are saved there, too.

When your business or school sets up their Exchange server, they choose what method your Exchange account uses to access email on the server. This will determine how your email works. Here are the possibilities - ask your business or school how your Exchange account is set up:

  • Exchange ActiveSync; MAPI/HTTP are methods for accessing your Exchange email, usually from a laptop, phone, or tablet. When you access or read your email, you aren't actually downloading or storing email on your mobile device; instead you're reading it from the Exchange Server. It allows you to access your email even when you're not connected to the Internet.

  • IMAP, like Exchange ActiveSync, is a method for accessing your email wherever you are, from any device. When you read an email message using IMAP, you aren't actually downloading or storing it on your computer; instead, you're reading it from the Exchange Server.

    With IMAP, email in your Inbox, Deleted Items, Sent Items folders are synchronized between your device and the server. IMAP allows for limited calendar storage but does not support collaborating on a calendar with other users.

  • POP email is downloaded from the Exchange Server onto your computer. Once email is downloaded to your computer, it's deleted from the server. To access the email after it's downloaded, you have to use the same computer. If you access your email from different computer or device, it will look like some of your previously downloaded messages have been deleted.
