G Suite IMAP and the email node


So I've been working on trying to get external mail working with a pager flow I'm building. In some of my testing at home, I've been able to get the email node to work just fine with normal gmail accounts, but my particular institution uses G Suite as our mail provider. I've been picking at getting IMAP to work with my mail and security admins, but have had pretty much zero luck.

What I'm asking is this: has anyone out there had any success with getting the email node to work with G Suite at all? If so, are there any particular recommendations/caveats?
