Click the Email Accounts icon



To access your webmail for the main account, you would use this link, but we're not going to do that

Instead, click More



Then click Access Webmail



Type the password for this email address NOT your cPanel password



Now click Log In



Click the webmail application available to you... in this case we'll select Horde



This is the Horde webmail main screen, where we can check our inbox...



... and compose a New Message



We're not going to get into the specifics of using the Horde webmail application... but suffice it to say that this is how you access, and manage your emails from within cPanel



When finished with web mail, click Logout
