O365 - puzzlepeaches/CredMaster GitHub Wiki
The O365 module is for brute-forcing Office365 instances using the "autodiscover-s.outlook.com" URL method. This works for both Managed/Federated environments.
This plugin does not require any additional arguments.
TBD, more research required (feel free to PR with notes)
