Hosted Exchange 2010 Access Protocols
Hosted Exchange supports many protocols that will allow you to connect to the Exchange server to access your information. Certain connections provide access to more information than others, but all of the connections provide access to your email information.
Messaging Application Programming Interface is the traditional connection used to interface with the Microsoft Exchange server and was designed by Microsoft. It allows the Exchange server to directly communicate with the email client, so that all of your information is updated in real time. This is the recommended connection to use when setting up your email client.
RPC over HTTPS
This is a special function that allows for secured access when connected to the Microsoft Exchange server.
Post Office Protocol (Version 3) is what most users need and use today. POP3 is a client/server protocol in which email is received and held on a mail server. Periodically, you check for mail on that server and then download it to your email client. POP3 is the standard protocol built into practically every email client. This method is well-suited for users that don't want to store email messages online.
Internet Message Access Protocol (Version 4) is another popular way to access email messages. With IMAP, messages and folders are always stored on the mail server. When users access their email, they are working directly with these messages. This means that any updates made to the email, such as moving, flagging, or marking a message as unread, is stored on the server.
IMAP is a convenient option for users who need to access their email online from multiple clients at multiple computers or locations.
Our IMAP server supports IMAP IDLE, which provides real-time push support for IMAP applications, alerting you the second you have new mail... which makes it very powerful for users on the go.
Simple Mail Transfer Protocol is the standard protocol for sending email messages across the Internet. It is also commonly referred to as the outgoing mail server. Our SMTP servers are configured to require SMTP Authentication. The servers themselves perform two important functions. First, they verify that anyone attempting to send outgoing email through the SMTP server has the right to do so. Then secondly, they send the outgoing email. If undeliverable, the mail gets sent message back to the sender.
SSL and TLS Encryption
We provide SSL and TLS encryption for POP3, IMAP, SMTP, and Outlook Web Access. Basically, this encrypts your data so that others cannot view it. Our servers also support opportunistic TLS, which allows your incoming and outgoing email data to be encrypted as it travels through the internet. This is very important for passwords and confidential emails.
RFCs are standards for email communication between servers and email clients. These standards are approved by the Internet Engineering Task Force (IETF) and are known as RFCs. These standards cover SMTP, POP, and IMAP, among other Internet technologies.
