Running everyday is not recommended, especially if you're just starting out. Your body needs time to recover, and over training can do more harm than good. You can still do some form of activity on your rest days - you don't have to take a break from exercising altogether, but I would advice against running everyday.
From Road Runners Club of America:
"Take a day off when needed. Beginners should NOT run every day. Every other day (three or four runs a week) is plenty. A day off gives muscles a chance to rest, and encourages runners to try other activities to keep their program varied and interesting." www.rrca.org/runners/getting-started/
