❓ Has anyone explored creating a singer tap for MSFT 365 admin data sources (graph API) and OneDrive usage in general? Does anyone have any tips on how to get started or if there is an open source example with Graph Auth via service principal to any data in general

yes to graphapi. no to onedrive usage. https://hub.meltano.com/taps/ms-teams

Thanks, it looks like the one drive usage account detail is very much like the team drive usage stream in that project
