While former Secretary of State Hillary Clinton is busy learning all sorts of lessons from her alleged faux pas of using personal email accounts to conduct U.S. Department of State business, Mark Ashton of Fox Rothschild says there are practical takeaways for anyone using an office server for email.

“Perhaps your electronic musings don't have the importance of communications from the Secretary of State, but you should know that the law is clear,” he says. “You are entitled to no expectation of privacy if you use an office computer to carry your personal email.”

So whether you're emailing your spouse to set up dinner plans or your attorney to confirm a tax return through a Gmail, Yahoo or MSN account, an employer has the right to retain and review those emails. Ashton notes that while not every office is actively doing this, it's generally a function of the server and not driven by office policy.
