- Product
- Microsoft Copilot
- Device & OS
- not provided
- Scenario
- Determining the correct tenant configuration and understanding privacy obligations for using AI services within China.
- Observed behavior
- Data privacy obligations and compliance rules differ significantly depending on whether the service is provided through a locally hosted 21Vianet tenant or a globally hosted Microsoft 365 tenant.
Ensure you have global administrator access to your Microsoft 365 Admin Center to verify your tenant's hosting location and service agreements.
Identify Tenant Type and Review Compliance Settings
Determine if your organization uses a local 21Vianet tenant or a global tenant to establish the correct data residency and compliance framework.
Data residency and personal information processing regulations in China require organizations to strictly monitor cross-border data transfers. Microsoft 365 operated by 21Vianet is physically hosted in China to meet these local regulatory demands, whereas standard Microsoft 365 tenants store data globally.
Before deploying Copilot, you must audit your tenant's architecture and consult local data processing terms.
Log in to the Microsoft 365 Admin Center, navigate to 'Settings', and click on 'Organization profile'. Check the 'Data location' tab to confirm whether your services are hosted in China (21Vianet) or globally.
Access the Microsoft Purview compliance portal. Navigate to the 'Data Residency' or 'Privacy' sections to read the specific service descriptions and data-processing agreements applicable to your tenant's region.
If you plan to use a globally hosted tenant via a VPN-based access method in China, schedule a review with your organization's legal and compliance teams to ensure the cross-border data transfer complies with local privacy laws.

Ensure Data Privacy with WPS Office
If you are navigating complex data residency regulations with cloud-based AI tools, consider WPS Office as a secure, locally-installable productivity suite. WPS Office provides exceptional compatibility with Microsoft formats while giving you complete control over your local data.
- 1. Download the installer: Visit the official WPS Office website and click the free download button for your operating system.
- 2. Install the software locally: Run the downloaded installer file and follow the on-screen instructions to set up WPS Office on your local machine, ensuring all files remain on your device.
- 3. Open and edit your files: Launch WPS Office and open your existing Microsoft Office documents. You can instantly start editing with full formatting support.

Frequently Asked Questions
Can I use Copilot in a globally hosted Microsoft 365 tenant from China?
Yes, but accessing a globally hosted tenant from China often involves cross-border data transfers. You must consult your legal and compliance specialists to evaluate local data privacy laws and the compliance of VPN-based access methods.
What is the difference between Microsoft 365 operated by 21Vianet and the global version?
Microsoft 365 operated by 21Vianet is a localized service physically hosted within China to comply with local data residency requirements. The global version is hosted on international servers and is subject to Microsoft's global compliance standards rather than specific localized regulations.
How do I check my organization's data residency settings?
You can view your organization's data location by logging into the Microsoft 365 Admin Center, selecting 'Settings', clicking 'Organization profile', and reviewing the 'Data location' tab.
