What's Actually Included in Microsoft 365 for Small Business?

3 May 2026

When people hear "Microsoft 365 for business", most assume it's just an Outlook email account with a company name in the address. It's considerably more than that.

Here's a clear breakdown of what's actually included — and why it represents genuine value for small businesses at £8/month per user.

Professional domain email

The headline feature: your own branded email address using your domain. Instead of yourbusiness@gmail.com, you get you@yourbusiness.co.uk. Every email you send reinforces your business name and looks professional to whoever receives it.

You can set up as many addresses as you need — info@, sales@, yourname@, admin@ — each with their own mailbox.

Outlook

Outlook is one of the most widely used business email clients in the world, and for good reason. It handles high email volumes well, has excellent calendar integration, and plays nicely with every other Microsoft tool. If you've ever used Outlook in an employed role, you already know how to use it.

Microsoft Teams

Teams gives you a full communication hub — instant messaging, video calls, voice calls, and file sharing, all in one place. For a small business, this replaces the need for a separate video calling tool and makes internal communication much simpler.

OneDrive (1TB cloud storage)

OneDrive gives you a terabyte of cloud storage per user for the Business Basic plan. Files stored in OneDrive are accessible from any device, can be shared with clients or collaborators via a link, and are automatically backed up. No more emailing files to yourself or losing documents when a laptop dies.

Office Web Apps

The Business Basic plan includes browser-based versions of Word, Excel, PowerPoint, and OneNote. For most everyday document tasks — writing proposals, managing spreadsheets, creating presentations — these are fully capable without needing to install anything.

50GB mailbox

50GB per user is substantial. Most small businesses never get close to filling it, which means you're not constantly archiving old emails or worrying about storage limits.

Security and spam filtering

Microsoft 365 includes built-in spam filtering, malware protection, and phishing defences. Properly configured, it significantly reduces the amount of junk that reaches your inbox and keeps your business communications secure.
