SharePoint is the part of Microsoft 365 that everyone has and almost nobody understands. It quietly powers your Teams files, your company intranet and your shared documents - yet ask ten business owners what it is and you will get ten shrugs. Here is the plain-English version: what SharePoint actually does, where it helps, where it goes badly wrong, and whether it is worth your attention.
SharePoint in one honest sentence
SharePoint is a place to store, organise and share your company's documents and information in the cloud, with proper structure and permissions - think of it as your firm's shared filing system and internal website rolled into one.
If you already pay for Microsoft 365, you already have SharePoint. It is the engine underneath: when you save a file in a Teams channel, that file actually lives in SharePoint. So the real question is rarely 'should we buy it' - it is 'should we use it deliberately instead of by accident'.
What businesses actually use it for
Stripped of the jargon, SharePoint does a few genuinely useful jobs that most firms struggle with otherwise.
- •Shared document storage: one organised home for company files, replacing the chaos of email attachments and a sprawling old file server.
- •Team and project sites: a dedicated space per department or project, with its own files, links and pages, and access limited to the right people.
- •Company intranet: a simple internal website for policies, news, forms and 'where do I find...' answers, so knowledge is not trapped in people's heads.
- •Co-authoring and version history: several people edit the same document safely, and you can roll back to any earlier version.
SharePoint vs OneDrive - the confusion that costs you
The single most common SharePoint mistake is muddling it with OneDrive, and it leads to real problems when staff leave.
The rule is simple: OneDrive is for your individual work - your personal drafts and files, like your own drawer. SharePoint is for shared, company-owned content - the team filing cabinet everyone uses. Files that the business depends on should live in SharePoint, not in one person's OneDrive, because when that person leaves, their OneDrive can go with them. Getting this boundary right is the difference between an organised firm and a fragile one.
Where SharePoint goes wrong
SharePoint has a reputation for being confusing, and it is earned - but almost always through poor setup rather than the tool itself.
Left to grow organically, it becomes a digital junk drawer: dozens of overlapping sites, files duplicated everywhere, nobody sure where the latest version lives, and permissions so tangled that either everyone sees everything or nobody can find anything. The technology is not the problem; the lack of a deliberate structure is. A small amount of upfront design - a clear site layout, sensible naming, thought-through permissions - is the entire difference between SharePoint that helps and SharePoint that staff quietly route around.
Should you use it - and the backup catch
If you are on Microsoft 365, the answer is usually yes, but with intent. Used well, SharePoint replaces a creaking on-site file server, supports remote work naturally, and keeps company knowledge in one secure place. Used carelessly, it adds to the mess. The deciding factor is whether you will set it up properly, not whether it is capable.
One warning that catches firms out: SharePoint is not a backup. Microsoft keeps the service running and offers limited recycle-bin retention, but it will not save you from mass deletion, ransomware, or a need to recover a file from two years ago. Pair it with real backup - see our backup software guide and the 3-2-1 rule. And because SharePoint underpins so much, securing the accounts that reach it via identity and access management matters more than people assume.
