With Microsoft continuing to push organizations toward cloud services, particularly Microsoft 365 and SharePoint Online, an interesting question remains: Is there still a reason to deploy and maintain SharePoint Server on-premises?
For some organizations, the answer is absolutely yes. For others, moving to SharePoint Online makes considerably more sense. Bear in mind, for me personally, SharePoint Server has kept me busy for over 25 years.
I think the problem is that the conversation often becomes about which platform is better, rather than understanding what the organization actually needs.
The Argument for SharePoint Server On-Premises
SharePoint Server Subscription Edition continues to provide organizations with a supported platform for document management, collaboration, intranet portals, workflows, and business applications within their own infrastructure.
One important point that often gets overlooked is that SharePoint Server Subscription Edition remains actively supported under Microsoft’s Modern Lifecycle Policy and continues to receive updates, security improvements, and new capabilities. It is not simply an obsolete product being maintained for organizations unwilling to move to the cloud. Microsoft continues to invest in the platform, recognizing legitimate business and technical reasons to maintain on-premises environments.
For organizations in highly regulated industries, with limited internet connectivity, or where data residency and infrastructure control are critical, maintaining SharePoint on-premises can still make sense. Existing investments also raise questions. Some organizations have spent years developing SharePoint solutions, integrating them with internal systems, building custom applications, and establishing processes around the platform.
Moving those environments to SharePoint Online is not necessarily a simple migration. It can require redesigning applications, replacing customizations, changing authentication approaches, and retraining users.
On-premises SharePoint also offers greater control over certain infrastructure, deployment, configuration, and operational decisions. Organizations can determine how the environment is managed, when updates are applied, and how it integrates with systems that cannot easily move to the cloud.
However, that control comes with responsibility. Servers, security updates, SQL Server, backups, disaster recovery, monitoring, and ongoing administration remain the organization’s responsibility.
The Argument for SharePoint Online
SharePoint Online offers a different approach, particularly for organizations already invested in Microsoft 365. Rather than maintaining the underlying SharePoint infrastructure, organizations can concentrate on collaboration, information architecture, governance, and the user experience. Integration with Microsoft Teams, OneDrive, Microsoft Purview, Power Automate, and the wider Microsoft 365 ecosystem provides capabilities that are difficult to replicate in a traditional on-premises environment.
Microsoft also continues to introduce new cloud capabilities, including AI-driven experiences, modern collaboration features, and deeper integrations across Microsoft 365.
There are practical benefits as well. Reduced infrastructure management, continuous service improvements, built-in scalability, and easier collaboration with external users can make SharePoint Online an attractive option.
But moving to the cloud does not automatically solve existing problems.
Poor information architecture, excessive permissions, unmanaged content, weak governance, and low user adoption do not disappear just because Microsoft hosts the platform. In some cases, those problems become considerably more visible.
A Practical Decision Framework
Rather than starting with whether to move to the cloud, I would start by examining what the organization needs SharePoint to accomplish.
Several areas are worth evaluating before making that decision.
| Consideration | SharePoint Server On-Premises | SharePoint Online |
|---|---|---|
| Data and compliance | Appropriate when requirements demand direct infrastructure control, internal hosting, or isolated environments. | Appropriate when regulatory and data-handling requirements can be satisfied within Microsoft 365. |
| Infrastructure | Requires organizations to operate, secure, maintain, and update their SharePoint and SQL Server environments. | Microsoft manages the underlying service infrastructure, reducing operational overhead. |
| Customization | Offers greater flexibility for certain server-side customizations and integrations with legacy systems. | Supports modern extensibility, APIs, Power Platform, and cloud-based integration models. |
| Collaboration | Well suited to internal collaboration, particularly within controlled corporate networks. | Strong integration with Teams, OneDrive, external sharing, and Microsoft 365 collaboration services. |
| Security | Provides direct control over infrastructure security, network boundaries, patching, and configuration. | Provides access to Microsoft Entra ID, Purview, Defender, and cloud-based security capabilities, subject to licensing. |
| Costs | Involves infrastructure, licensing, administration, maintenance, and disaster recovery costs. | Involves recurring subscriptions, licensing considerations, and potentially migration or modernization costs. |
| User adoption | May align well with established business processes and existing applications. | Can support broader adoption through familiar Microsoft 365 applications and integrated workflows. |
The table provides a useful starting point, but the real decision requires looking beyond individual features.
First, identify the non-negotiable requirements. Do regulatory obligations, network restrictions, application dependencies, or security requirements genuinely prevent the organization from using SharePoint Online? Validate these rather than assume them.
Second, understand the existing environment. An organization with a heavily customized SharePoint environment may face a completely different migration challenge from one using SharePoint primarily for document libraries and intranet pages.
Third, calculate the actual cost of ownership. Comparing SharePoint Server infrastructure costs against Microsoft 365 licensing alone does not tell the complete story. Consider administration, migration, modernization, training, security, operational support, and ongoing maintenance.
Fourth, consider the organization’s direction. If the business is already adopting Teams, OneDrive, Power Platform, and other Microsoft 365 capabilities, SharePoint Online may provide a more natural foundation. If the organization operates primarily within isolated or tightly controlled infrastructure, SharePoint Server may remain the better fit.
Finally, and perhaps most importantly, evaluate adoption. How do employees currently use SharePoint? What problems does it solve? Are they comfortable with the existing processes? Will moving platforms improve productivity, or simply introduce change without delivering meaningful benefits?
The question should not be whether SharePoint Server or SharePoint Online has more features. It should be which platform best supports the organization’s requirements, users, and long-term direction.
The decision doesn’t have to be entirely one or the other. A hybrid approach may let organizations keep specific applications or workloads on SharePoint Server while adopting SharePoint Online for modern collaboration and other business needs.
For some organizations, that may be the most practical option, particularly when migration needs to happen gradually, or certain systems cannot be moved.
So, Which One Makes More Sense?
I don’t think this should be a cloud-versus-on-premises argument where one platform automatically wins.
SharePoint Server can still be a perfectly valid choice when clear technical, regulatory, operational, or business requirements justify maintaining the environment. Importantly, with Subscription Edition continuing to receive support and updates, organizations can make that decision as part of a deliberate long-term strategy rather than simply treating on-premises SharePoint as a temporary solution.
SharePoint Online makes sense when organizations want to leverage the broader Microsoft 365 ecosystem, reduce infrastructure responsibilities, and embrace the continuous development of cloud services.
There may even be situations where using both platforms is appropriate.
Ultimately, the decision should come down to business requirements, technical constraints, long-term strategy, and perhaps most importantly, adoption.
You can deploy the latest SharePoint Online environment with every modern feature available, or maintain a carefully designed on-premises SharePoint farm. Neither matters particularly much if employees don’t understand why they should use it, cannot find what they need, or continue working around the platform.
The technology is only part of the solution.
The real measure of success is whether SharePoint delivers value to the organization and whether people actually use it.
