Optiv's Go365 tool does some awesome bruteforcing & enum for Office365 tenants. Would be great to have a CredMaster plugin for it, with an optional --endpoint flag to specify RST or Graph.

I could probably do it myself, theres just a lack of time in this world, would appreciate if someone tried their hand with a PR!

Update, looks like the graph method of the go365 tool is the same as the msol plugin of CM, but the rst method is new
