Microsoft 365 support in Lujiazui

Microsoft 365 support in Lujiazui 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 Lujiazui 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 Lujiazui is not like migrating anywhere else

People assume the global tenant and the China service differ only in where the servers sit. They don’t: licensing, feature behaviour and routing all vary, and performance is a function of how your traffic reaches Microsoft’s network. Layer the compliance question on top — what you may store where, and what you can demonstrate — and you have a design problem rather than a copy operation.

Nobody touches a mailbox until the audit is done: what you are licensed for, how Domains and DNS are set, which mail rules exist, how Teams and SharePoint are genuinely used, how identity is configured, and where the devices are enrolled. A straightforward tenant move take a few weeks end to end.

What we migrate

• Mailboxes, mail flow and shared mailboxes
• Teams, channels and chat history, where the move allows 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

Mailboxes move first, then the collaboration content, so people keep working while the rest follows.

How a migration runs

1. Audit the current tenant and the actual business requirements
2. Settle the destination design: tenant, licensing, routing
3. Run a pilot group and record what actually changes for users
4. Cut over in a planned window; we schedule it around your team’s calendar
5. Hypercare — we stay on through the settling-in period, while the small faults surface
6. 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 Lujiazui 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 before

Our 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?

Very little, if the cutover is planned properly: mail flow flips inside a window, users sign in again, work resumes. The time goes into the days afterwards — profiles, devices, shared mailboxes, and the odd Teams channel that behaves differently.

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.
