You manage Microsoft 365 across a global company with central identity and security, consistent configuration, sensible licensing, and a clear joiners and leavers process. Done well, every office works the same way, access is controlled wherever people are, and you are not paying for licences nobody uses. Microsoft 365 is the backbone of most firms’ daily work, so managing it properly matters across all of it.

A sprawling, unmanaged Microsoft 365 tenant gets messy and risky. Here’s how to keep a global one in good order.

1. Central identity and security

Managing identity centrally, with MFA and access by role, means a single change protects every office at once. It is the foundation of keeping a global tenant secure and consistent.

2. Consistent configuration

Email, files, sharing and security settings should follow the same sensible standard everywhere. Consistency makes the environment easier to support and avoids one office being set up less securely than another.

3. Sensible licensing

Across a global company, licences add up. We help you match licences to what people actually need and remove unused ones, so you get the right tools without overspending.

4. Clear joiners and leavers

People join, move and leave constantly in a global firm. A clear process to set up and remove access promptly keeps both security and licensing tidy, with no lingering accounts.

A real example: M365 managed across offices

We supported a software company serving financial trading firms with Microsoft 365 administration across offices in the UK, the US and Asia-Pacific, handling mailboxes, distribution groups and licensing centrally so the environment stayed tidy and consistent across every location.

For most technology and trading firms, this sits within fully managed IT at about £45 to £100 per user per month, billed per user, with the security and resilience these businesses rely on built in.
