Microsoft 365 support in Yuexiu

A Microsoft 365 support project in Yuexiu looks simple on a spreadsheet and rarely stays that way. The first question is the one nobody asks outside China: the global Microsoft tenant, or the local 21Vianet service? From there it becomes a design exercise — keeping mail flowing, Teams history intact, and an audit trail your head office can actually read.

For foreign-owned companies in Yuexiu 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.

What makes Microsoft 365 support in Yuexiu a different project

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.

The audit comes before any mailbox is touched: licences, domains and DNS, mail rules, how Teams and SharePoint are genuinely used, identity configuration, and which devices are enrolled where. Most migrations then take a few weeks to cutover.

What we migrate

• User and shared mailboxes, plus the mail-flow rules around them
• Teams, channels and chat history, where the move allows it
• SharePoint and OneDrive content, with permissions verified on both sides
• Entra ID, groups, sign-in policy and conditional access
• Endpoint policy and Intune device enrolment
• DNS records, domains, and the licence position on the new 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 for a weekend
5. Hypercare — we stay on for the fortnight after cutover, 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 Yuexiu 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.

The questions that come up every time

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.
