A client recently go a new Samsung Galaxy S4. I set up his exchange email account, which is through office 365. We noticed that he was receiving text messages on his phone as well as his email.
On the phone:
Open e-mail inbox go to settings, you will see your email address here with a tick
Press it and scroll down to "More Settings"
Scroll to "Sync SMS" and untick it.
