SharePoint vs OneDrive: Understanding the Difference
One of the most common questions we hear from Microsoft 365 users is about the difference between SharePoint and OneDrive. Both are cloud storage solutions from Microsoft, both integrate tightly with the rest of the Microsoft 365 ecosystem, and both can be accessed from anywhere on any device. So when should you use each? And why does it matter?
Getting this right has a real impact on your business. When files are stored in the wrong place, teams waste time searching for documents, version control breaks down, sensitive information ends up in personal storage where it cannot be governed, and offboarding becomes a nightmare. We have seen organisations lose critical project files when a team member leaves, simply because everything was saved in their personal OneDrive rather than a shared SharePoint library.
This guide breaks down the practical differences between SharePoint and OneDrive, explains when to use each, and provides a framework for setting up a file management strategy that works for your whole organisation.
What Is OneDrive for Business?
OneDrive for Business is your personal cloud storage space within Microsoft 365. Think of it as the cloud equivalent of your personal documents folder - a private area where you control what is stored and who can see it. Every Microsoft 365 user gets their own OneDrive with 1TB of storage by default (some licence tiers offer up to 5TB).
Files stored in OneDrive are private to you unless you explicitly share them. You can share individual files or folders with specific colleagues, giving them either view-only or edit access. OneDrive syncs seamlessly with File Explorer on Windows and Finder on Mac via the OneDrive sync client, so your cloud files appear as if they are stored locally on your device.
Key characteristics of OneDrive for Business:
Personal storage - owned by and tied to an individual user account
1TB storage per user as standard (expandable with certain licences)
Private by default - files are only accessible to the owner until shared
Syncs with desktop via the OneDrive client for offline access
Supports Known Folder Move for backing up Desktop, Documents, and Pictures
Version history tracks changes and allows rollback
What Is SharePoint Online?
SharePoint Online is a team-based collaboration platform. It goes well beyond simple file storage, providing shared document libraries, intranet sites, workflow automation, and content management capabilities for groups of people. SharePoint is designed around the concept of "sites" - each site is a shared workspace with its own document libraries, permissions, and settings.
When you create a Microsoft Teams team, a SharePoint site is automatically created behind the scenes to store all the shared files. This is an important detail that many users do not realise - every file you share in a Teams channel is actually stored in a SharePoint document library. SharePoint is the backbone of collaborative file storage across the entire Microsoft 365 platform.
Key characteristics of SharePoint Online:
Shared storage - owned by a team, department, or project rather than an individual
25TB base storage plus 10GB per licensed user across the tenant
Granular permissions - control access at site, library, folder, and file level
Integrates directly with Microsoft Teams, Power Automate, and Power Apps
Supports metadata, content types, and custom views for organising documents
Files persist when individual team members leave the organisation
When to Use OneDrive
Use OneDrive when you are working on something individually and do not need others to access it yet. It is your personal workspace for content that is not ready to be shared or that genuinely belongs only to you. Common use cases include:
Work-in-progress documents - Drafts of reports, presentations, or proposals that you are still developing before sharing with the wider team.
Personal notes - Meeting notes, to-do lists, and reference materials that are relevant only to you.
Files shared by external contacts - When a supplier or client emails you a document, saving it to OneDrive first makes sense before deciding whether it needs to move to a shared location.
Desktop and Documents backup - Known Folder Move automatically syncs your local Desktop, Documents, and Pictures folders to OneDrive, protecting against device failure or loss.
A good rule of thumb: if you are the only person who needs this file, or if it is a draft that will eventually move to a shared location, OneDrive is the right home for it.
When to Use SharePoint
Use SharePoint when files need to be accessible to a group of people, when content has a lifecycle beyond a single individual, or when you need structured governance and permissions. If a document would cause problems if only one person could access it, it belongs in SharePoint. Common use cases include:
Project documentation - Everything related to a project should live in a shared SharePoint site or Teams channel so the whole project team can access, contribute, and review.
Company policies and procedures - HR policies, health and safety documentation, employee handbooks, and standard operating procedures need to be accessible to the right groups and controlled centrally.
Templates and brand assets - Shared templates for proposals, invoices, letterheads, and other branded materials ensure consistency and save time.
Departmental resources - Finance, marketing, operations, and other departments each benefit from a dedicated SharePoint site with their own document libraries and shared resources.
Client-facing deliverables - Final versions of reports, proposals, and contracts that may need to be accessed by multiple team members over time.
The key advantage is continuity. When someone leaves the organisation, team files in SharePoint remain accessible to everyone else with the appropriate permissions. Files in a departing employee's OneDrive require administrator intervention to recover, and there is a risk of data loss if the account is deleted before those files are transferred.
How SharePoint and Teams Work Together
Understanding the relationship between SharePoint and Microsoft Teams is crucial for getting the most out of both. Every Teams team has a SharePoint site. Every Teams channel has a corresponding folder in that SharePoint site's document library. When you upload a file to a Teams channel, it is stored in SharePoint. When you open the "Files" tab in a channel, you are looking at a SharePoint library.
This means you have two ways to access the same files: through the Teams interface (which is great for quick access during conversations) or through the SharePoint site directly (which provides more advanced features like metadata columns, custom views, content approval workflows, and detailed version history). Encouraging your team to understand this connection prevents confusion and helps people choose the right tool for the task.
Private channels in Teams create separate SharePoint sites with their own permissions, which is worth knowing from a governance perspective. If you have sensitive information in a private channel, be aware that it lives in a separate SharePoint site that needs to be managed alongside your main team site.
Best Practices for Your Organisation
The most effective approach is to use both platforms in tandem, with clear guidelines so everyone knows where to save different types of content. Here is a practical framework we recommend to our clients:
Create a clear information architecture. Before rolling SharePoint out broadly, plan your site structure. Map it to your organisational hierarchy, project portfolio, or business functions. A typical structure might include a company-wide intranet site, department sites (Finance, HR, Operations, Sales), project sites for major initiatives, and a central policy library. This prevents the chaos of ad hoc site creation.
Establish naming conventions. Consistent naming for sites, libraries, and folders makes content discoverable. Agree on conventions for project sites (e.g., "PRJ - Client Name - Project Name"), document libraries, and file naming. This sounds mundane, but it saves enormous amounts of time as your content grows.
Use metadata instead of deep folder hierarchies. One of SharePoint's most powerful features is metadata - custom columns that tag documents with attributes like document type, client, project phase, or status. Instead of creating five levels of nested folders, use metadata columns and filtered views. This makes documents much easier to find and allows the same document to appear in multiple views without duplication.
Train your teams. The best information architecture in the world is useless if your staff do not understand it. Invest time in showing people the difference between OneDrive and SharePoint, demonstrate how to save files in the right location, and provide a simple reference guide they can keep at their desk. We find that short, role-specific training sessions work far better than generic all-hands presentations.
Common Pitfalls to Avoid
After helping hundreds of UK businesses with their Microsoft 365 environments, we see the same mistakes repeated frequently. Here are the most common pitfalls and how to avoid them:
Defaulting to OneDrive for everything. This is the most common and most damaging mistake. When staff save all their work to OneDrive, it creates data silos that are invisible to the rest of the organisation. Permissions cannot be managed centrally, search results are fragmented, and when someone leaves, their files may be lost. Make SharePoint the default for any business content that others may need to access.
Creating too many SharePoint sites without governance. At the other extreme, some organisations allow anyone to create SharePoint sites and Teams teams without any oversight. This leads to content sprawl, duplicated sites, and confusion about which site is the "real" one for a given topic. Implement a site creation policy and consider using approval workflows for new site requests.
Ignoring external sharing settings. Both OneDrive and SharePoint allow sharing with external users, but the default settings may be more permissive than your organisation requires. Review your tenant-level sharing policies and set appropriate restrictions. For regulated industries or businesses handling sensitive data, you may want to restrict external sharing to specific domains or require guest accounts.
Not planning for offboarding. When an employee leaves, their OneDrive data is retained for 30 days by default (extendable to 10 years) before deletion. If you do not have a process for reviewing and migrating their files during this window, important business data could be permanently lost. Build OneDrive content review into your offboarding checklist.
Security and Compliance Considerations
Both OneDrive and SharePoint benefit from the same Microsoft 365 security infrastructure, including encryption at rest and in transit, DLP policies, and sensitivity labels. However, SharePoint gives you significantly more control over governance. You can apply retention policies to ensure documents are kept for the required period (important for UK regulatory compliance), set up content approval workflows, and audit who has accessed or modified files.
For businesses subject to regulations like UK GDPR, FCA requirements, or NHS data standards - where compliance pressure is a constant concern - SharePoint's governance features make it the more appropriate choice for regulated content. Sensitivity labels can be applied to SharePoint sites to automatically enforce access controls, encryption, and data protection policies based on the classification of the content stored there.
