Microsoft 365 support in Xuhui
A Microsoft 365 support project in Xuhui 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.
NETK5 plans and runs Microsoft 365 support work in Xuhui for foreign-owned businesses: a pre-migration audit, tenant and licence review, the cutover itself, and the support in the weeks afterwards when the small problems surface. Global tenant or 21Vianet — that choice drives everything else.
What makes Microsoft 365 support in Xuhui 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.
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. Typical migrations take two to four weeks end to end.
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 verified on both sides
- Identity — Entra ID, groups, authentication and conditional access
- Endpoint policy and Intune device enrolment
- DNS records, domains, and the licence position on the new tenant
We move mailboxes first and collaboration content second, which keeps the team productive while the remainder follows.
How the project runs, step by step
- Establish what you have today against what the business genuinely needs
- Settle the destination design: tenant, 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 Xuhui 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.
Our experienceSince 2002 we have looked after IT for international companies in China, and Microsoft 365 sits at the centre of most of it. We have run a pilot migration of Microsoft 365 from the global tenant to 21Vianet for a client operating in China, and we manage cloud estates day to day — including an environment of more than thirty Azure virtual machines with Microsoft 365 alongside it. Our clients include names such as Siemens, Nestlé, McKinsey and JLL, usually alongside the international IT companies 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.
