What Was Happening
A small business in Wimbledon SW19 had outgrown the email it started with. Like a lot of new businesses, it had been running on a free, generic mailbox — fine at the very beginning, but it looks unprofessional on a business card, it doesn’t scale across a team, and it gives you none of the calendar sharing, Office apps, or central control that a growing business needs.
What they wanted was straightforward to describe and easy to get wrong: professional email carrying the business’s own domain name rather than a generic free-mail address, the Office applications, and shared calendars the team could actually rely on. They asked us to set it up properly rather than piecing it together themselves, because email that’s misconfigured tends to fail quietly — messages bounce, or worse, appear to send but never arrive.
Our Diagnosis
We talked through the options and settled on Microsoft 365 Business as the right fit: it bundles the email, the desktop and web Office apps, OneDrive storage, and the management controls a small business benefits from, for a predictable per-user monthly cost.
The part that needs care is the domain. For mail to flow to a Microsoft 365 mailbox, the domain has to be verified as genuinely owned by the business, and several DNS records have to be put in place — an MX record to route incoming mail, an SPF record so other mail servers trust that Microsoft is allowed to send on the domain’s behalf, and an autodiscover record so Outlook configures itself. Get any of these wrong and you get the classic symptoms: bounced messages, mail landing in spam, or Outlook refusing to connect. So the plan was to set the tenant up, prove ownership of the domain, and lay the DNS records down correctly before creating a single mailbox.
How We Fixed It
We set up the Microsoft 365 tenant and added the business’s domain, then verified ownership by publishing the verification record Microsoft provides. With the domain verified, we configured the DNS records that route and authenticate the mail — the MX record pointing to Microsoft, the SPF record authorising it to send, and the autodiscover record that lets Outlook find its settings automatically.
We then created the mailboxes for the team and configured Outlook on their devices, signing each user in and confirming that mail sent and received correctly on the new addresses. We checked the shared calendars worked across the team and that the Office apps were activated. Because the records were correct from the outset, there was no period of bouncing mail or missing messages to chase afterwards.
The Result
The business left the visit with professional email live on its own domain, the Office apps installed and activated, and shared calendars working across the team — all configured and tested before we left. Email now looks the part on their domain, and because it’s a managed Microsoft 365 setup rather than a free mailbox, they can add staff, reset passwords, and recover accounts centrally as the business grows.
Why Businesses Move to Microsoft 365
Free, generic email is fine for a side project, but it holds a real business back in three ways. It looks unprofessional to customers. It doesn’t give you central control — when someone leaves, you can’t easily lock their account or recover their mail. And it lacks the collaboration tools, shared calendars, and document storage that a team needs to work together.
Microsoft 365 solves all three, but the email-routing side is genuinely fiddly, and it’s where DIY setups come unstuck. The DNS records that make business email reliable — MX for routing, SPF (and ideally DKIM and DMARC) for authentication — are invisible when they’re right and baffling when they’re wrong, because the failure mode is usually “some mail just doesn’t arrive” rather than a clear error. That’s the part worth getting a professional to set up once, correctly.
Getting a Microsoft 365 Move Right
- Don’t change the MX record until the new mailboxes exist — point mail at an empty tenant and it bounces.
- Set SPF correctly, and consider DKIM and DMARC too — these are what stop your domain being spoofed and keep your mail out of recipients’ spam folders.
- Preserve old mail — if you’re moving from an existing provider, migrate the existing mailboxes rather than starting empty and losing history.
- Set up every device while you’re at it — desktop Outlook, webmail, and phones — so nobody is locked out the next morning.
- Keep the admin login safe and separate — the global admin account controls everything; protect it with multi-factor authentication.
