Microsoft M365 in China: What You Need to Know
Using Microsoft 365 in China: What International Businesses Need to Know in 2025
Operating an international business in China presents distinct IT challenges—especially when using cloud-based platforms like Microsoft 365. Due to China’s strict data sovereignty laws, Microsoft services in China are operated by 21Vianet, resulting in a separate, localised version of Microsoft 365 that differs significantly from the global tenant.
At PTS Managed Services, we help businesses understand these differences and implement IT strategies that comply with local laws while maintaining global productivity. Here's what you need to know.
Key Differences Between Microsoft 365 Global and China Cloud (21Vianet)
1. Data Sovereignty and Regulatory Compliance
Global Tenant: Data is stored in Microsoft’s global data centres, governed by standards like GDPR.
China Tenant (21Vianet): Data is stored entirely within China to comply with local regulations. This isolation means Chinese and global tenants cannot share the same infrastructure.
2. Feature Availability and Product Gaps
Global M365: Includes full features such as Microsoft Teams Live Events, Audio Conferencing, Power Platform integration, and access to the latest productivity tools.
M365 in China: Many features are limited or unavailable, including:
Microsoft Teams Live Events
Power Automate connectors
Windows Autopilot
Integration with Google services
Limited Teams bots and third-party apps
⚠️ These feature limitations may impact workflow, especially for teams that rely on automation, hybrid work tools, or mobile device management.
3. Network Performance and User Experience
Users in China accessing Global M365: Often experience high latency, packet loss, and poor video call quality due to cross-border data routing and the Great Firewall.
China Cloud users: Benefit from faster, more stable access, but lose integration with global services.
Microsoft Intune and Endpoint Management in China
Device Management Differences
Global Intune: Offers full functionality, including Android Enterprise support, Windows Autopilot, Exchange connectors, and telemetry.
Intune via 21Vianet:
No support for Windows Autopilot
No Google Mobile Services (impacts Android MDM)
Intune Company Portal may not be available or delayed in the China app stores
Implication for IT Teams
You’ll likely need to segment device policies between users in China and global users.
Global MDM policies may need to be customised or removed altogether for China-based devices.
Licensing, Support, and Updates
Global M365: Supported directly by Microsoft, with uniform global updates and roadmap features.
China M365:
Supported by 21Vianet, not Microsoft directly.
Update cycles differ, with delays in feature rollouts, patches, and support availability.
Strategies for International Businesses Using M365 in China
To operate effectively across China and other regions, businesses must create a bifurcated IT strategy that considers both versions of Microsoft 365.
Recommended Approaches:
Local China Tenant for Mainland Operations: Ensures compliance and optimal performance.
Global Tenant for Other Offices: Maintains full feature access for teams outside of China.
Bridge Gaps with Process Design: Redesign workflows to accommodate limited integrations and support dual processes where needed.
Employee Training: Ensure your team understands the differences and potential workarounds.
Ongoing Monitoring: Stay informed on the evolving Microsoft and 21Vianet roadmaps.
