Microsoft 365 support in Yizhuang
Microsoft 365 support in Yizhuang is one of those projects that looks tidy in a plan and rarely stays that way. The first fork in the road is China-specific: stay on the global Microsoft tenant, or move to the 21Vianet-operated service? Everything afterwards — mail flow, Teams history, the audit trail your head office asks for — follows from that one decision.
For foreign-owned companies in Yizhuang we take the whole journey: audit, then tenant and licence design, then cutover, then the settling-in weeks when the odd fault surfaces. The aim is a migration nobody has to talk about afterwards.
Why Microsoft 365 support in Yizhuang is not like migrating anywhere else
A global Microsoft 365 tenant and the China-operated service are not the same product with a different logo. Licensing differs, some services behave differently on each side, and performance depends on how traffic is routed between your offices and the nearest Microsoft edge. Add the compliance question — where personal data may legally sit, and what you can evidence to a regulator or a head office — and the migration becomes a design exercise, not a copy job.
We audit before anyone touches a mailbox: licence entitlements, domains and DNS, mail flow rules, Teams and SharePoint usage, identity configuration, and which devices are enrolled where. Most migrations take a few weeks from audit to cutover.
What we migrate
- Mailboxes, mail flow and shared mailboxes
- Teams and channels, carrying chat history across where the move supports it
- SharePoint and OneDrive content, with permissions checked before and after
- Entra ID, groups, sign-in policy and conditional access
- Endpoint policy and Intune device enrolment
- Domains, DNS records and the licensing picture on the destination tenant
We move mailboxes first and collaboration content second, which keeps the team productive while the remainder follows.
How a migration runs
- Audit the current tenant and the actual business requirements
- Design the destination — tenant choice, licensing, routing
- Pilot with a small group and measure what really changes for users
- Cut over in a planned window; we schedule it outside business hours
- Hypercare — we stay on for hypercare, while the small faults surface
- Leave you with documentation, and keep supporting the estate afterwards
Where we work
We are not a single-city provider. NETK5 dispatches engineers across mainland China: our own team is based in Shanghai, Beijing, Guangzhou and Hong Kong, and we staff projects elsewhere in the country as clients need them — Xi’an, Chengdu, Taixing and beyond. Outside China we have delivered rack-and-stack work and WiFi surveys in Japan, Korea, Singapore and Taiwan, usually for international companies coordinating several sites from a head office that has never been on site.
For Microsoft 365 support in Yizhuang that matters in a practical way: work can be planned around a visit rather than a relocation, and the same team that surveys or installs can hand over documentation the head office can actually use.
Where we have done this beforeOur China practice dates back to 2002 and Microsoft 365 work sits at its centre. We ran a pilot migration from the global tenant to 21Vianet for a client here, and we run cloud estates day to day — one of them more than thirty Azure virtual machines alongside Microsoft 365. Siemens, Nestlé, McKinsey and JLL are among the names we work with, generally alongside the international IT firms whose client sites we support.
Questions we get asked
Do we have to move to 21Vianet if we are in China?
It is a choice, not a requirement. Many foreign-owned companies stay on the global tenant and live with the trade-offs: performance, routing, and how easy it is to evidence how data is handled. We also handle moves the other way, from 21Vianet back to global, when a business restructures or exits. Your users, your regulator and your head office decide it, which is why the audit comes first.
How long are users without email?
In a well-planned cutover, not at all in any meaningful sense: mail flow switches in a window and users sign in again afterwards. What takes time is the settling-in — profiles, devices, shared mailboxes, and the occasional Teams channel that behaves unexpectedly.
Can you support us after the migration?
Yes, and a good share of our migration work becomes ongoing support — helpdesk in English and Chinese, monitoring, and someone who already knows how your tenant was built.
