For most companies, email, documents, calendars and video calls now come from one of two subscription suites. Choosing between Microsoft 365 vs Google Workspace affects how your staff work every day and is tedious to reverse, so it deserves more thought than comparing the cheapest plan on each pricing page. This guide compares them on the points that matter in practice and offers a simple way to decide.
The short version
- Microsoft 365 suits organisations that rely on desktop Word, Excel and Outlook, exchange complex documents with clients, use Windows PCs managed centrally, or need advanced compliance features.
- Google Workspace suits organisations that work mainly in the browser, value real-time co-editing and simplicity, and have mixed devices such as Chromebooks, Macs and phones.
Both are mature, secure and reliable. Either will run a small or mid-sized business well. The deciding factors are usually habits, existing files and integrations.
Microsoft 365 vs Google Workspace at a glance
| Area | Microsoft 365 | Google Workspace |
|---|---|---|
| Exchange Online, used via Outlook (desktop, web, mobile) | Gmail, used mainly in the browser and mobile app | |
| Documents | Word, Excel, PowerPoint; desktop apps on Business Standard and higher | Docs, Sheets, Slides; browser-first |
| File storage | OneDrive (personal) and SharePoint (team sites) | Google Drive and shared drives |
| Meetings and chat | Microsoft Teams | Google Meet and Google Chat |
| Device management | Intune on Premium plans; deep Windows integration | Endpoint management built into the admin console |
| AI assistant | Microsoft Copilot | Gemini |
| Admin experience | Powerful, many separate admin centres | Simpler, single admin console |
Plan names, included features and bundling change over time, and some products (Teams being a notable example) have been packaged differently by region. Always check the current plan comparison pages from Microsoft and Google before buying.
Documents and collaboration
Google built its suite in the browser from the start, and it shows. Several people editing the same Sheet simultaneously, with comments and suggestions, is smooth and natural. Sharing a link is the default way of working, which reduces the "which version is final?" problem.
Microsoft has closed much of that gap; Word, Excel and PowerPoint support co-authoring in the browser and the desktop apps when files live in OneDrive or SharePoint. Where Microsoft still clearly leads is in the depth of the desktop applications. Finance teams with large Excel models, macros and Power Query, or legal teams exchanging heavily formatted Word documents with outside firms, often find Google's equivalents limiting.
Email and calendar
Both handle business email well, with good spam filtering, shared mailboxes and calendar delegation. The difference is mostly in style. Gmail uses labels and search rather than folders and is designed around the web interface. Outlook is folder-based, has a powerful desktop client and is familiar to anyone who has worked in a corporate environment. A Google Workspace mailbox can be used from Outlook, and an Exchange mailbox from other mail apps, but each service is at its best in its own client.
Administration and security
Google's admin console is easier for a non-specialist to understand: users, groups, devices and security settings are in one place. Microsoft's admin tools are spread across several centres (Microsoft 365 admin, Entra ID, Exchange, Intune, Purview, Defender), which can be daunting but offers very fine control.
Either way, apply the basics on day one:
- Enforce multi-factor authentication for every user, especially administrators.
- Use separate admin accounts rather than giving daily-use accounts admin rights.
- Set up SPF, DKIM and DMARC for your domain so your mail is trusted and harder to spoof.
- Restrict external file sharing to what the business needs.
- Consider a third-party backup; built-in retention is not the same as an independent backup.
You can confirm your domain's mail records are published correctly with our DNS lookup tool, checking the MX and TXT records. A correct SPF record for each suite looks like this:
; Microsoft 365
example.com. TXT "v=spf1 include:spf.protection.outlook.com -all"
; Google Workspace
example.com. TXT "v=spf1 include:_spf.google.com ~all"Integration with the rest of your IT
If your staff sign in to Windows PCs joined to Active Directory, or you plan to use Azure, Microsoft 365 fits naturally because identities are shared through Entra ID. If you use Google Cloud, Chromebooks or many SaaS tools that favour Google sign-in, Workspace is the smoother fit. Both support single sign-on to thousands of third-party apps through SAML and OpenID Connect.
Migrating between them
Both vendors provide migration tools for mail, calendars and contacts, and third-party tools cover files and shared drives. The technical part is manageable; the human part is harder. Allow time for training, expect some formatting issues when converting complex documents, and plan the MX record cutover carefully, lowering the TTL beforehand so mail flows to the new system quickly. Our cloud solutions page outlines how such migrations can be planned.
How to decide
- List the five tools your staff use most and how they use them (desktop Excel, shared docs, video calls with clients).
- Check which suite your key clients and partners use; exchanging files is easier on the same platform.
- Consider who will administer it and how much complexity they can handle.
- Run a trial with a small group from different departments for two to four weeks.
Key takeaways
- Microsoft 365 is strongest for desktop Office users, Windows-managed fleets and advanced compliance.
- Google Workspace is strongest for browser-based collaboration and simple administration.
- Plan contents change, so compare current official plan pages rather than old reviews.
- Whatever you choose, enforce MFA, configure SPF/DKIM/DMARC and back up independently.
