Google Apps Sync for Microsoft Outlook (Gmail)

If you plan on using Outlook with CSE Gmail, you might consider using Google Apps Sync for Microsoft Outlook (https://tools.google.com/dlpage/gappssync). This will allow you to sync not only mail (as with the IMAP solution below), but also contacts and calendars, similar to what you would expect from a Microsoft Exchange server.

Microsoft Outlook (Microsoft Cloud)

If you plan on using Outlook with CSE Microsoft Cloud, you might consider using Microsoft Outlook in MAPI mode. This will allow you to read not only mail (as with the IMAP solution below), but also contacts and calendars, similar to what you would expect from a Microsoft Exchange server.
