If your business uses Microsoft 365, there’s a good chance you’re already interacting with SharePoint even if you don’t realize it.
Maybe employees collaborate on documents through Microsoft Teams. Maybe different departments need a shared place for files. Or perhaps your organization has outgrown traditional shared drives and employees are constantly emailing documents back and forth.
SharePoint helps bring that information together.
Microsoft SharePoint is a platform within the Microsoft ecosystem that businesses can use to store, organize, share, and manage information across their organization. It can support everything from shared document libraries and project collaboration to company intranets, department sites, internal resources, and secure file sharing.
But SharePoint is much more than cloud file storage.
When it’s structured properly, it can become a central part of how employees find information and work together.
So what exactly does SharePoint do and does your business actually need it?
What Is Microsoft SharePoint?
Microsoft SharePoint is a collaboration and content-management platform that allows organizations to create sites where employees can store files, organize information, communicate, and work together.
Instead of company information being scattered across individual computers, email attachments, old shared drives, and miscellaneous folders, SharePoint can provide centralized locations for employees to access the resources relevant to their work.
A business might create separate SharePoint sites for:
- Human Resources
- Accounting
- Marketing
- Sales
- Operations
- Individual projects
- Company policies
- Employee resources
- Leadership
- Client or vendor collaboration
Each site can then contain its own documents, pages, lists, permissions, and otherresources.
Microsoft describes SharePoint as a platform organizations can use to share and manage content, knowledge, and applications across the organization.
What Is SharePoint Used For?
There isn’t one single way businesses use SharePoint.
A small company might primarily use it as a central location for shared documents. A larger organization might have dozens of SharePoint sites supporting departments, projects, internal communications, and business processes.
Some common business uses include:
Document Management: SharePoint document libraries give employees a centralized location for business files rather than storing everything on individual computers or sending attachments back and forth.
Team Collaboration: Employees can work with shared documents and information without maintaining separate copies on everyone’s computer.
Company Intranets: Businesses can use SharePoint to create an internal company site containing announcements, policies, employee resources, links, forms, and other frequently used information.
Department Sites: HR, accounting, sales, marketing, and other departments can have dedicated spaces for their own documents and resources.
Project Collaboration: Teams working on a project can maintain relevant files and information in one central location.
External Collaboration: Organizations can configure SharePoint to share certain information with customers, vendors, contractors, and other external users.
Business Processes: SharePoint lists and its integrations with other Microsoft tools can also support workflows and processes that go beyond basic document storage.
The important thing is that SharePoint should be designed around how your organization actually works rather than becoming another place where employees dump files.
How Does SharePoint Work?
SharePoint becomes much easier to understand when you stop thinking about it as one enormous cloud drive.
Think of it as a structure.
Your Microsoft 365 Environment
↓
SharePoint Sites
↓
Pages, Document Libraries & Lists
↓
Folders, Files & Information
A site creates a workspace for a particular team, department, project, or purpose.
Inside that site, you can have document libraries containing files, pages displaying information, and lists used to organize structured information.
Permissions then determine who can access those resources and what they’re allowed to do with them.
That structure is one of the reasons planning is so important. If every department begins creating sites, folders, and permissions without an overall strategy, SharePoint can become just as disorganized as the systems it was supposed to replace.
What Is a SharePoint Document Library?
Document libraries are where SharePoint starts becoming especially useful for everyday business operations.
A SharePoint document library is a location within a site where users can store, organize, access, and collaborate on files.
But it isn’t simply a folder sitting in the cloud.
Depending on how your environment is configured, document libraries can support features such as:
- File sharing
- Permissions
- Version history
- Metadata
- Search
- Real-time collaboration
- File organization
- Integration with Microsoft 365 applications
For example, instead of your HR department keeping policies inside:
Shared Drive → Company → HR → Documents → Policies → Current
You could have an HR SharePoint site with a dedicated Policies document library where approved employees know exactly where those documents belong.
Good SharePoint architecture can make information easier to find without relying entirely on complicated layers of folders.
SharePoint Version History: What Happens When a File Changes?
One useful SharePoint feature for businesses is version history.
Rather than employees creating:
Proposal.docx
Proposal-Final.docx
Proposal-Final-NEW.docx
Proposal-Final-NEW-v2.docx
SharePoint can maintain previous versions of a document as changes are made.
Depending on configuration, users may be able to see when a file changed, who changed it, and restore an earlier version when necessary.
This can be particularly useful when someone accidentally overwrites information or a team needs to review how a document has changed over time.
Microsoft also describes version history as part of SharePoint and OneDrive’s built-in data-protection and recoverability capabilities.
SharePoint Permissions Explained
Putting company information in one central location is useful—but only if the right people can access the right information.
That’s where SharePoint permissions come in.
For example, your entire company may need to read an employee handbook, while only HR employees should be able to edit it.
Your accounting department may need access to financial information that shouldn’t be available to everyone else.
A project may also include an outside contractor who only needs access to a specific set of files.
SharePoint permissions allow organizations to control these different levels of access.
You will commonly encounter groups such as:
Owners:
Users responsible for managing the site and its content.
Members:
Users who actively contribute and collaborate.
Visitors:
Users who primarily need to read information.
However, SharePoint permissions can become complicated when organizations begin creating numerous unique permissions for individual files and folders.
A better strategy is generally to structure access intentionally and follow the principle of least privilege: employees receive the access they need to do their jobs without automatically receiving access to everything.
Permissions should also be reviewed over time as employees change roles, projects end, outside users no longer require access, and the organization evolves.
Can You Share SharePoint Files Outside Your Business?
Yes. SharePoint can be configured to support collaboration with people outside your organization.
This can be useful when working with:
- Clients
- Vendors
- Contractors
- Consultants
- Business partners
- Other third parties
But external sharing should be controlled carefully.
SharePoint supports different types of sharing links, and they don’t all provide the same level of control.
For example, Microsoft documents options including Anyone, People in your organization, People with existing access, and Specific people links. “Anyone” links can potentially be forwarded to others and don’t require authentication, whereas a “Specific people” link is intended for designated recipients.
Before enabling widespread external sharing, businesses should decide:
- Who is allowed to share information externally?
- What information can be shared?
- Which sharing methods are appropriate?
- How long should external users retain access?
- Who is responsible for reviewing old access?
Convenient file sharing shouldn’t come at the expense of control over company information.
Can You Share SharePoint Files Outside Your Business?
SharePoint includes security and access-management capabilities, but simply moving your files into SharePoint doesn’t automatically create a secure information-management strategy.
Security still depends heavily on how the environment is configured and managed.
Businesses should think about several layers of protection.
Identity: How are users proving who they are? Multi-factor authentication can provide another layer of protection if a password becomes compromised.
Permissions: Can employees only access the sites and information appropriate for their roles?
External Sharing: Who can send company files to users outside the organization?
Devices: Are the computers and mobile devices accessing company information properly protected?
Accounts: Are old, inactive, and former employee accounts being properly managed?
Employees: Do employees understand phishing, suspicious login attempts, unsafe sharing practices, and unexpected MFA requests?
Monitoring: Would your organization recognize suspicious account activity or inappropriate access?
SharePoint security should therefore be considered part of your broader Microsoft 365 security strategy, not managed as an isolated system.
SharePoint vs. OneDrive: What's the Difference?
This is one of the most common sources of confusion in Microsoft 365 because both platforms can store files.
The easiest way to understand the difference is:
OneDrive = Your Work
OneDrive is generally intended for an individual’s work files.
You may be creating a document yourself, working on something that isn’t ready for the rest of your department, or storing files associated primarily with your own work.
SharePoint = Our Work
SharePoint is designed around information that belongs to a team, department, project, or organization.
If the accounting department needs a document regardless of whether a particular employee is working that day, it probably shouldn’t exist exclusively in that person’s OneDrive.
For example:
Draft presentation you’re still working on → OneDrive
Final marketing materials everyone needs → SharePoint
Your personal working notes → OneDrive
Company policies → SharePoint
Department templates → SharePoint
Shared project files → SharePoint
Microsoft similarly advises users to think about whether a document is an individual work file or something being worked on as a team when deciding between OneDrive and SharePoint.
How Are Microsoft Teams and SharePoint Connected?
Here’s where Microsoft 365 gets interesting.
If your company uses Microsoft Teams, you may already be using SharePoint without realizing it.
Teams provides employees with the communication and collaboration interface they’re familiar with, while SharePoint plays an important role behind the scenes for file storage and collaboration.
For example, files associated with a Microsoft Team are stored in the connected SharePoint environment.
So when an employee goes into Teams and accesses a shared document, SharePoint may actually be handling the underlying file storage.
This is why Teams and SharePoint shouldn’t necessarily be planned as completely separate systems.
The way your organization structures Teams can affect your SharePoint environment, file organization, permissions, and overall Microsoft 365 governance.
Can SharePoint Replace a Traditional File Server?
For some businesses, SharePoint can reduce or replace certain uses of traditional file servers.
But this shouldn’t be treated as a simple:
File Server → Upload Everything → Done.
Traditional file servers and SharePoint don’t work exactly the same way.
Before migrating, businesses should consider:
- What types of files are being stored?
- How large are the files?
- How are employees currently accessing them?
- Are any applications dependent on existing file paths?
- How complicated are the existing permissions?
- Are employees working remotely?
- Which information should move?
- Which information should be archived?
- How should SharePoint sites and libraries be structured?
This is also an opportunity to clean up old information rather than migrating years of digital clutter into a new platform.
A poorly planned SharePoint migration can simply recreate your messy shared drive in the cloud.
SharePoint for Remote and Hybrid Businesses
SharePoint can be particularly useful for businesses whose employees don’t work from one central office every day.
Instead of requiring employees to access documents stored on an office server, SharePoint can make appropriately permissioned company information available through Microsoft 365.
Employees can collaborate on shared documents whether they’re working:
- In the office
- From home
- At another company location
- While traveling
- Across different departments
This can reduce reliance on emailing attachments back and forth or maintaining separate copies of the same document.
However, remote accessibility also makes identity security, device management, MFA, permissions, and access controls especially important.
Convenience and security need to be designed together.
Common SharePoint Mistakes Businesses Make
SharePoint can solve organizational problems, but a poorly managed SharePoint environment can create new ones.
Recreating Your Entire Shared Drive: If your current file server has 15 layers of confusing folders, copying the exact same structure into SharePoint doesn’t fix the underlying organization problem.Use migration as an opportunity to rethink how information should be structured.
Creating Too Many Sites: Creating a new site for every tiny project can eventually leave employees wondering where anything lives.Establish rules around when a new site should actually be created.
Giving Everyone Too Much Access: “Just give them access to everything” might solve today’s support ticket, but it creates unnecessary security exposure.
Forgetting About External Users: A vendor may legitimately need access today.That doesn’t necessarily mean they should still have access two years from now.
No Naming Standards: “Marketing,” “Marketing Team,” “Marketing New,” and “Marketing 2026” are eventually going to confuse somebody. Nobody Owns the Environment Someone needs responsibility for SharePoint governance, permissions, site creation, external sharing, and overall organization.
Moving Everything Without Cleaning It Up: You probably don’t need every file your company has created since 2008.Migration is an excellent time to archive, delete, consolidate, and reorganize.In the office
SharePoint Backup, Recovery and Versioning
SharePoint provides built-in capabilities that can help users recover from certain mistakes, including recycle-bin functionality and version history.
But businesses shouldn’t assume that version history, retention, recycle bins, and backup are all the same thing.
They’re not.
Your organization should understand:
- What information is being protected
- How long deleted information remains recoverable
- What your retention requirements are
- What happens after accidental deletion
- How information would be recovered following malicious activity
- What happens when an employee leaves
- Whether additional backup capabilities are appropriate
Your recovery strategy should be based on your organization’s actual data and business-continuity requirements.
What Happens to SharePoint Access When an Employee Leaves?
Employee offboarding should include more than disabling an email account.
When someone leaves the organization, businesses should consider the Microsoft 365 resources that person had access to.
That may include:
- SharePoint sites
- Microsoft Teams
- Shared documents
- OneDrive
- Microsoft 365 groups
- Shared mailboxes
- External resources
- Administrative privileges
- Business applications
Their access should be removed appropriately, but the organization should also make sure important business information remains available to the employees who still need it.
A documented Microsoft 365 onboarding and offboarding process can help prevent forgotten accounts, unnecessary access, and lost information.
Not every organization needs a complicated SharePoint deployment.
But it may be worth considering if your employees constantly ask:
“Where is that file?”
“Which version is the newest one?”
“Can you send me that document again?”
“Who has access to this folder?”
“Why can’t I get to the shared drive from home?”
You may also benefit from SharePoint if your organization:
- Uses Microsoft 365 extensively
- Has remote or hybrid employees
- Needs centralized document storage
- Has files scattered across employee devices
- Wants an internal company resource center
- Collaborates heavily through Microsoft Teams
- Needs better document access controls
- Frequently works on documents as a team
- Shares information with vendors or clients
- Has outgrown its current shared-file structure
The question isn’t simply whether SharePoint has useful features.
It’s whether those features solve an actual problem within your organization.
