Microsoft 365 is a strong fit for most Australian small businesses. It gives you a professional email address on your own domain, a shared calendar and files your whole team can access, and — when it's properly protected and backed up — a secure inbox, typically billed as a predictable monthly cost per user rather than a large upfront purchase.

Who Microsoft 365 suits

Microsoft 365 scales from a single home-based operator right up to a larger team, which covers the vast majority of small businesses across Australia. It's worth considering if you:

  • Use a free or consumer email address (Gmail, Outlook.com) and want to look more established
  • Have a small team who need a shared calendar, files or group inbox
  • Are on Microsoft 365 already but feel you're paying too much, or waiting too long for support

Why business owners put it off — and what actually matters

The usual hesitation is that it sounds like an IT project. It doesn't need to be one, but it's worth being clear-eyed about what's actually at stake if the setup is left half-done. Small businesses hit by cybercrime in FY2024–25 lost an average of $56,600 per incident, up 14% on the year before (ACSC Annual Cyber Threat Report 2024–25).

What tends to matter more than the software itself is whether protection and recovery are built in from the start, rather than treated as something to configure later. In practice, that means checking that:

  • Security is switched on by default, not something you have to know to ask for
  • There's a way to recover something that's gone missing — a deleted folder, a lost thread — without a drawn-out process
  • Pricing is simple and predictable, so it's easy to budget against month to month
  • Support from an actual person is available if something goes wrong

Common questions

Is Microsoft 365 good for a small business in Australia? Yes — it's one of the world's most widely used business email and productivity platforms, and it scales from one person to a 20-person team without needing in-house IT.

Do I need an IT person to set it up? Not necessarily. A guided, automated setup can take minutes with no technical knowledge required, though it's worth checking what level of support is available if something does come up.

Is Microsoft 365 secure by default? Base Microsoft 365 includes baseline protection, but many businesses layer on additional security and backup rather than relying on the defaults alone — it's worth understanding the gap before you decide what you need.

How should it be priced? Look for pricing that leads with a single, predictable monthly amount covering email, security and backup together, rather than treating protection as a separate line item you have to opt into.

Where to next

Curious exactly what's included when people talk about "Microsoft 365 for small business" — and whether that covers tools like Teams? That's the next question worth answering.
