Do I need to license external users for SharePoint Server?
Last reviewed by the MSLicenseHub Licensing Desk.
No separate per-user license is needed for external users — Microsoft Product Terms include external user rights with the SharePoint Server license. An external user is defined as someone who is not an employee, contractor or vendor of your organization or an affiliated entity.
The catch: those rights apply to your SharePoint Server, hosting your content for your business. You cannot stand up a SharePoint Server to host content for a third party — that is a Service Provider scenario and requires the Service Provider License Agreement (SPLA).
Apply this to your deployment
- Server
- Internal access
- Edition features
Check each installed server and the internal user/device access rights. Enterprise CAL features can require an additive CAL rather than replacing Standard. External-user exceptions and Subscription Edition requirements differ by product.
Decision checklist
| Check | What to record |
|---|---|
| Product and version | Record the full name, edition, version and part number in the quote. |
| Scope of use | Identify the user, device or deployment; count only the metric applicable to this product. |
| Evidence and support | Retain the agreement, invoice and support lifecycle date; perpetual licensing does not mean perpetual support. |

Practical checklist
- For SharePoint Server on premises, external users need licensing through CALs or the server's external-user rights as described in the Product Terms.
- SharePoint Server Subscription Edition keeps the server + CAL model; check the current Product Terms for external user rules.
- For SharePoint Online, guests are invited through Microsoft Entra B2B and many scenarios are covered by the tenant's licensing.
- Document which external users have access and why, for audits.
Common mistakes to avoid
- Assuming internet-facing sites need no licensing review.
- Giving partners internal accounts without CALs.
- Confusing SharePoint Online guest rules with SharePoint Server rules.
