SharePoint vs OneDrive: What Is the Difference and Which Should Your Business Use?

If your business uses Microsoft 365, you already have both SharePoint and OneDrive — whether you realise it or not. They both store files in the cloud, they both sync to your computer, and in File Explorer they can look almost identical. So it's no surprise that this is one of the most common questions we get from Australian small businesses: what's actually the difference, and which one should we be using?

The short answer: OneDrive is for individual files, SharePoint is for company files. Get that distinction wrong and you end up with the problem we see constantly — critical business documents scattered across the personal OneDrive accounts of staff members, invisible to everyone else and gone the moment that person leaves.

This guide explains what each tool is for, how they work together, and how to structure your files so your team can actually find things.

What Is OneDrive?

OneDrive for Business is each staff member's personal cloud storage within your Microsoft 365 tenancy. Every user with a licence gets their own OneDrive (typically 1 TB), and by default, only they can see what's in it.

Think of it as the modern replacement for the “My Documents” folder or a personal home drive on an old file server. It's the right place for:

• Drafts and works in progress — documents that aren't ready for the team yet
• Personal working files — notes, templates you use individually, meeting prep
• Files you occasionally share one-to-one — sending a single document to a colleague for feedback

The critical point: a OneDrive account is tied to a person, not the business. When an employee leaves and their account is deactivated, their OneDrive content is typically retained for only 30 days by default (extendable, but many businesses don't change it). If your client contracts, pricing spreadsheets or project files live in a departing staff member's OneDrive, you have a real problem.

What Is SharePoint?

SharePoint is Microsoft 365's platform for shared, company-owned file storage — plus intranet pages, lists and workflows, though most small businesses use it primarily for document libraries.

Files in SharePoint belong to a site, not a person. A site might represent a department (Finance, Operations), a function (Policies & Procedures), or a client project. Access is controlled by group membership, so when someone joins the accounts team, they get access to the Finance site — and when they leave, the files stay exactly where they are.

SharePoint is the right place for:

• Anything more than one person needs — client files, project documents, templates, procedures
• Records the business must retain — contracts, financial records, HR documentation
• Files that need structured permissions — payroll visible to two people, marketing assets visible to everyone

Here's the part that surprises many business owners: if you use Microsoft Teams, you're already using SharePoint. Every team you create in Teams gets a SharePoint site behind it, and every file uploaded to a Teams channel is actually stored in that site's document library. Teams is just a friendlier front door. If your team channels are a mess, your SharePoint is a mess — our Microsoft Teams setup guide covers how to structure teams and channels properly from day one.

SharePoint vs OneDrive at a Glance

The Most Common Mistakes We See in Australian Businesses

1. Running the whole business out of one person's OneDrive

This is by far the most common setup we inherit: the owner or office manager keeps “the company files” in their personal OneDrive and shares folders out to staff one at a time. It works — until that person is on leave, changes roles, or resigns. Shared links break, permissions become impossible to audit, and nobody can say with confidence who can see what. Company files belong in SharePoint, full stop.

2. Treating sync as backup

Files syncing to the cloud feels safe, but sync is not backup — a file deleted or encrypted by ransomware on your laptop is deleted or encrypted in the cloud within seconds. Microsoft's built-in retention helps, but it's limited. We've covered this in detail in Does Microsoft 365 Back Up Your Data? — the short version is that a third-party backup of both SharePoint and OneDrive is cheap insurance.

3. Creating a new Team for every small thing

Because every Team creates a SharePoint site, a business that creates Teams freely ends up with 40 sites, most abandoned, with files duplicated across several of them. A 10–30 person business usually needs somewhere between 4 and 10 well-named Teams/sites, not dozens.

4. Lifting the old file server into SharePoint as-is

Copying a 15-year-old file server structure — with its 12 levels of nested folders — straight into SharePoint creates real problems. SharePoint has path length limits, deep nesting breaks sync, and old permission chaos comes along for the ride. A migration is the one chance to restructure; our cloud migration guide for small business walks through how to plan it properly.

5. Sharing sensitive files with “Anyone with the link”

Microsoft 365's default sharing settings are often more permissive than businesses realise. If you handle client records, financial data or health information, unrestricted anonymous links are a Privacy Act incident waiting to happen — and increasingly something cyber insurers ask about. Sharing defaults should be locked down to “people in your organisation” with external sharing enabled only where genuinely needed.

How They Work Together in Practice

SharePoint and OneDrive aren't competitors — Microsoft designed them as a pair, and a healthy setup uses both:

1. Draft in OneDrive. A staff member starts a proposal in their OneDrive while it's rough.
2. Move to SharePoint when it's team business. Once it's ready for review, it moves (not copies) into the relevant SharePoint library or Teams channel.
3. Collaborate in place. Multiple people co-author the same document simultaneously — no more “Proposal_FINAL_v7_JohnsEdits.docx” emailed around.
4. Sync what you need. The OneDrive sync app on Windows and Mac can sync both your personal OneDrive and selected SharePoint libraries to File Explorer, so staff work with familiar folders while everything lives in the cloud.

That last point causes most of the confusion: because the OneDrive app is what syncs SharePoint libraries to your computer, people assume everything they see is “OneDrive”. It isn't — the app is just the delivery van. Where the files actually live is what matters.

Which Should Your Business Use?

Both — but with SharePoint doing the heavy lifting. For a typical Australian SMB with 5–50 staff, a sensible structure looks like this:

• A small number of SharePoint sites mapped to how your business actually works — e.g. Company-Wide, Clients/Projects, Finance & Admin, Management (restricted)
• Group-based permissions so access is granted by role, not by individual sharing links
• OneDrive for personal working files only, with staff trained on the “would it matter after I left?” rule
• Locked-down external sharing defaults, with exceptions granted deliberately
• Third-party backup covering both SharePoint and OneDrive
• An offboarding process that reviews and transfers a departing user's OneDrive before the account is deleted

Since both tools are included in every business Microsoft 365 plan, there's no extra licensing cost to using them properly — if you're weighing up plans, see our breakdown of what Microsoft 365 costs in Australia in 2026.

Getting the Migration Right

If you're moving from a file server, Dropbox, Google Drive or a tangle of OneDrive shares into a proper SharePoint structure, the work is 20% technical and 80% planning. The steps that matter:

1. Audit what you have. Identify what's current, what's archive, and what can be deleted. Migrating rubbish just moves the problem.
2. Design the site and permission structure first. Decide the sites, the libraries, and who gets access to what — on paper, before touching anything.
3. Migrate in stages. Move one department or site at a time, verify it, then move on. Big-bang migrations over a weekend are where files go missing.
4. Train staff on the new structure. Fifteen minutes explaining where things live and the OneDrive-vs-SharePoint rule saves months of drift back to old habits.
5. Switch on backup and lock down sharing as part of go-live, not as an afterthought.

This is exactly the kind of project we handle as part of our managed IT services — including the ongoing administration that keeps the structure tidy after month one.

The Bottom Line

OneDrive and SharePoint aren't rivals — they're two halves of how files should work in Microsoft 365. OneDrive is each person's private workspace; SharePoint is the business's filing system. The businesses that get this right have files that are findable, permissions that are auditable, and nothing that walks out the door when a staff member does.

The businesses that get it wrong usually don't notice until something goes missing — a departed employee's OneDrive, a broken sharing link, or a client file nobody can locate. A couple of hours of deliberate structure now prevents all of it.
