OneDrive Cloud Location

For OneDrive used with Microsoft 365 in Australia, customer data at rest is stored within the Microsoft 365 geography associated with the tenant, and Microsoft provides specific data residency commitments for that geography.

Key points from the provided information:

1. OneDrive is part of Microsoft 365 and follows Microsoft 365 data residency rules. All OneDrive data is stored within the customer’s tenant and follows the standard Microsoft 365 data storage guidelines by available geography.
2. Microsoft 365 has defined geographies and local region geographies (including Australia and New Zealand). Tenants in these local region geographies can have additional data residency commitments via Advanced Data Residency (ADR). For SharePoint and OneDrive, data location details are provided per service.
3. For Australian and New Zealand customers, Microsoft Entra ID (the identity platform behind Microsoft 365) stores identity customer data for directory management and authentication within Australian datacenters when the billing address is in Australia or New Zealand. Other Entra services may store data globally, but this is identity-related data, not OneDrive file content.
4. For Core Online Services (which include Microsoft 365 services such as OneDrive and SharePoint), Microsoft stores customer data at rest within certain major geographic areas (Geos) as defined in the Product Terms and the Microsoft Products and Services Data Protection Addendum (DPA). For services in scope of the EU Data Boundary, data is stored and processed within the EU, but this is specific to EU tenants.
5. OneDrive explicitly states that all data is stored within the customer tenant for the given service and follows Microsoft 365 data storage guidelines by available geography. For Australia, this means storage in the Microsoft 365 Australia Geo, subject to the commitments in the Product Terms and DPA.

To determine the exact data location for a specific Microsoft 365 tenant (including OneDrive and SharePoint), use the Microsoft 365 “Where your Microsoft 365 customer data is stored” documentation and the SharePoint and OneDrive data location section referenced there. These resources describe the geography (for example, Australia) where data at rest is stored for that tenant.

In summary: for an Australian Microsoft 365 tenant (business use, with an Australian address), OneDrive for Business data at rest is stored in the Microsoft 365 Australia geography in Microsoft datacenters located in Australia, in line with Microsoft’s data residency commitments for that region.
