Oh that’s pretty cool, thanks for the link. I’ve used davmail as a proxy like this, just for the oauth support, but it doesn’t scale to large mailboxes or high traffic well at all. May forward this along for some of our internal services people.

You can also use this (locally-hosted) proxy of mine which transparently adds OAuth 2.0 support to any IMAP/POP/SMTP client: https://github.com/simonrob/email-oauth2-proxy.
