Not if you are using an Exchange server released in the last decade.

The exchange server I use has it's web site enabled that works pretty well (granted, it's not as friendly as the full blown client.. but, works for me since I really only use it for email, my calendar and shared calendars).  You did make me think of one caveat... at work I'm required to use Lync (Lync messaging is built into the Exchange web-site but I can't make phone calls anymore without it).
