Each of these email protocols operates on a web-based system to transfer messages from a server. In addition, each one supports most, if not all, email clients. So, no matter what email client you choose, you can access your email on a remote server.

IMAP supports both online and offline account access. It provides advanced sync features, and lets you view and manage messages without removing them from the server. Therefore, any changes you make are saved and reflected from all locations.

The POP protocol lets you read email messages without a constant Internet connection. POP downloads the messages from your server to your local computer or phone. While you can save a copy of the messages on your server, changes made from the local device are not saved on the server.

The Exchange ActiveSync® protocol provides a robust syncing tool for all of your email, calendar, contacts, and other communications between your desktop, mobile device, or Internet connection. With your Hosted Exchange Email account and your Exchange ActiveSync-enabled phone, you have secure access to communications from anywhere.

For easy and safe access to your email accounts, IMAP is recommended. If you are a small business or need access to more than just email, Exchange provides the highest level of communication and syncing.

See Setting up Your Email with IMAP or Setting up Your Email with POP for general instructions, or see below for specific client setup instructions.

TIP: To ensure that a copy of your email messages is left on the server, you can modify the settings of your email client.

SMTP email problems are among the most common. While these problems are typically easy to find and fix, they often cause the most headaches for email account management. The first step is to identify the error or problem. Then, you can research the possible solutions and get back to emailing.

If you are unable to send email, you should:

• Verify your SMTP and account settings including the User Name and Password. See What are the SMTP Relay settings for my email client? TIP: The User Name is the full email address associated with the account.
• Make sure that your Firewall, AntiVirus, and ISP are not blocking the ports. Our SMTP server, on WIFI, is limited to the ISP's restrictions, so you may need to modify your port settings as indicated here.
• Check the bounceback information here and here. There are several reasons that a message might get bounced back. If there is a link in the error message, follow it to find and resolve the problem.

In addition to the above list, see What do I do if I have trouble connecting to my email? for more troubleshooting help.

Many mobile service providers use their SMTP server port as a default. In most circumstances, this doesn't need to be changed.
