title: How to get Mailbox list in batches of 100 using -ResultSize
body: <p>I have to fetch Exchange Mailboxes in batches of 100 (there are total 1m+ mailboxes in organization).<br>
  I am using the following powershell command:<br>
  <code>Get-Mailbox -ResultSize Unlimited</code><br>
  This gives me all the mailboxes which is taking long time. I can process the result in batches of 100 so I hit this command: <code>Get-Mailbox -ResultSize 100</code>.<br>
  Seems to work fine but I'm stuck on how to bring the next 100 mailboxes.  </p>
  
  <p>PS: You can assume that the mailboxes are static and no changes will be made on them for indefinite time...</p>
