When our team moved to Office 365, we wanted something declarative, and the only option was [Microsoft365DSC](https://microsoft365dsc.com/). We of course tried it, but the experience is subpar, went through hoops to set it up on Windows (no Linux, Mac support) and the output was a mix of imperative code and declarative specs, with GUI tool to help you manage. Seriously hope some Microsoft expert will create a Terraform provider for Microsoft 365. currently we have to use the Office 365 sluggish admin dashboards.
