title: change dns record for high number of email adresses
body: <p>My new client is using Office 365 accounts. his company has couple of email adresses. i built him a new website and planning to host it on my webserver. 
  i just want to make sure that i'm doing right:</p>
  
  <ol>
  <li>changing the dns (mx etc) records on his existing url to my host service.</li>
  <li>create "x" email adresses under his domain on my server (actually creating the same existing email adresses that they are using now).</li>
  <li>change dns for <strong>each</strong> email adress with office365 wizard.</li>
  </ol>
  
  <p>2 questions now:</p>
  
  <ol>
  <li>am i right?</li>
  <li>is there's any short way of doing that, am i forgetting something important, or this are the steps? 
  in other words: do i need to <strong>create every email adress</strong> on my host, and then enter <strong>every adress's office365 wizard and change the records</strong>?</li>
  </ol>
