Re: proficient in Outlook Express
Are you sure? I don't know any business that uses it.
Moreover, all e-mail programs are the same. They have an Inbox. That's filled automatically by incoming mail. And if you open such a mail (just click on it) they have a "Reply", "Reply to all" and "Forward" button. And the main window has a button to compose a new email, which in turn has a Send button to send the mail.
That's all you have to know to be able to use it quite well: read, reply, forward and send mails. If you can use one, you can use all in a business environment.
