I need to relay to an Exchange server that's about to be configured to

to configure Exim to authenticate *as a client* using OAUTH2?
I built an OAUTH2 plugin for Cyrus SASL and tried it, but it appears
that Exim's Cyrus SASL driver doesn't have a client side at all?

says
"OpenID Connect is a concrete protocol for authenticating users,
devised on top of the OAuth 2.0 framework.
As such OpenID Connect is also often called a profile of OAuth 2.0."

might be of interest, if your Exchange supports that profile.
