Webmail is the ability to access your business email account from any PC or Laptop in the world without using any applications such as MS Outlook, just like hotmail or yahoo mail and all in English.
You can use any industry standard Browser application such as MS Internet Explorer or FireFox just as you do to browse any normal website. You can then go to your email account by simply using the URL for your webmail access. You are then presented with a login page (see photo 1) which you can enter by using your email address and password. You are in and can now view your emails, compose new email, reply, forward and delete your email as if you were in the office (see photo 2).
