Microsoft M365: where is customer data stored and processed?

Microsoft's own privacy page states that customer data can be stored and processed within the EU under the EU Data Boundary, but this is general and not confirmed specifically for M365. The M365-specific data location is therefore not verified beyond that general statement. Lists of other possible storage countries (including Australia, Austria, Brazil, Canada, Finland, France, Germany, Hong Kong and India) are general datacentre lists and are not confirmed for M365. Telemetry, logs and analytics are described generally as possibly processed in the USA, without M365-specific confirmation. Customer group is not stated, and no data processing agreement, sub-processors or certifications were found in the pages retrieved.
