Google Apps Sync for Outlook

You aren't alone. If your company moved over to G Suite and you are now stuck in Google's less than user-friendly Gmail interface, don't fret. What most people don't know is that, if you're on a Windows based machine, you can continue to use Outlook to manage your mail, contacts, and calendars even after moving over to G-Suite. Meet Google Apps Sync for Outlook.

It's very easy to set up. All you need to do is login and it creates a new profile on your outlook for you. All of your emails, calendars, and contacts are immediately sync'd. Beware though, the default download is 1Gb so if your mailbox is bigger than that, you'll have to change the settings to ensure you get all of your historical email.
