Some of the disadvantages of using rich text formatting in your business e-mails is that they don't always convert when they're sent outside of one company to another company. So, in other words, I'm in a particular company, where they're using rich text formatting, and they e-mail out to another company, that company is going to convert it into plain text, as most companies do. Therefore you'll lose some of the formatting of rich text in your business e-mail as you communicate with someone in another company. Within the company itself, most companies allow that sort of HTML to HTML, or rich to rich, or plain to plain, but it becomes difficult when e-mailing out of the company.
