Hypertext Transfer Protocol (HTTP) is the protocol used to display Web pages but it can also be used to read e-mail with Outlook Web App (OWA). The advantage to OWA is that you can read, send, etc. e-mail from any computer with an Internet connection and a modern Web browser capable of supporting a secure connection (SSL). The Web address for OWA is https://mail.ad.uab.edu.

For any troubleshooting concerning OWA, send an e-mail to the This email address is being protected from spambots. You need JavaScript enabled to view it. ">AskIT Help Desk or call them at 205-996-5555. Microsoft also offers many tutorials and guides on their Web site.

Post Office Protocol (POP3) can be used by almost any client including Windows Mail and Mozilla Thunderbird. The difference between IMAP and POP3 is that POP typically pulls your e-mail messages off the server and stores them locally on your hard drive. This is fine unless a problem arises with your hard-drive, which may cause you to lose all messages stored on your machine. Your POP3 client will need to be capable of providing secure authentication.

Messaging Application Programming Interface (MAPI) is used by the full version Outlook client in conjunction with an Exchange mail server. MAPI is very much like IMAP but provides extended features within Outlook. This is only available in Outlook on a machine running Windows. You choose this protocol by selecting Microsoft Exchange Server within the Outlook e-mail account configuration.

The Exchange Web Services (EWS) protocol serves as the critical link in enabling secure synchronization between Microsoft Exchange Server 2010 systems and Snow Leopard-powered Macs.

Internet Message Access Protocol (IMAP) is the most common way to configure the Outlook for MAC mail clients. The benefit of using this protocol is that your e-mail messages remain on the server. When configured this way, you do not lose any e-mail messages should a problem arise with your personal computer and have the option of using Outlook Web Access when you so desire. Your IMAP client will need to be capable of providing secure authentication
