title: MsGraph shared mailbox operations
body: <p>Are the following operations possible through the MsGraph API.</p>
  <ul>
  <li>Add an user to a shared mailbox</li>
  <li>Create a shared mailbox</li>
  <li>Delete a shared mailbox</li>
  <li>Remove an user from a shared mailbox</li>
  <li>Rename a shared mailbox</li>
  </ul>
  <p>From my searches and reading the MsGraph API documentation I could not find any end point for doing the above apart from reading shared mailbox mails.  Is this correct ?  If this is not possible through the MsGraph API should I use the ExchangeAPI ?  I did some reading on the Exchange API and also could not find a proper endpoint to get this done.</p>
