How to Grant Access to an On-Premises SharePoint Link
Question details
The user needs to grant permissions to an on-premises SharePoint site linked from SharePoint Online, but lacks access because the site owner is away and SharePoint Online administrators cannot manage local server permissions.

- Product
- SharePoint Server
- Device & OS
- not provided
- Scenario
- Attempting to grant user access to an on-premises SharePoint Server site that is linked within a SharePoint Online portal.
- Observed behavior
- SharePoint Online administrators are unable to grant access to the linked on-premises site, as permissions must be managed directly in the local IIS-based server environment.
Verify whether the target link points to a SharePoint Online site or an on-premises SharePoint Server. You will need local administrator or site collection administrator credentials for the on-premises environment to make permission changes.
Contact the On-Premises SharePoint Administrator
Since SharePoint Online cannot manage on-premises site permissions, access must be requested through an authorized local administrator or another site collection administrator.
SharePoint Online and on-premises SharePoint Servers (such as those running on IIS 10) operate in separate permission environments. Even if a link to the on-premises site is placed in SharePoint Online, the security settings remain isolated.
If the primary site owner is unavailable, you must escalate the request to another local administrator.
Hover over or copy the link in SharePoint Online to determine the internal server URL (e.g., a local company domain) for the on-premises site.
Reach out to your organization's IT department or SharePoint Server Management team to locate a global administrator or secondary site collection administrator.
Provide the administrator with the site URL and ask them to grant the necessary user permissions directly within the on-premises SharePoint environment.

Frequently Asked Questions
Why can't I manage on-premises permissions from SharePoint Online?
SharePoint Online and on-premises SharePoint Servers operate in entirely different environments. Adding a link to a local site in an online portal does not bridge their permission structures, so local sites must be managed locally.
How can I tell if a SharePoint site is on-premises or online?
Check the URL of the site. SharePoint Online URLs typically end in 'sharepoint.com', whereas on-premises URLs usually feature a custom company domain or an internal server name (often hosted on IIS).
What should I do if the on-premises site owner is unavailable?
If the primary site owner is on vacation or otherwise unavailable, you should contact your organization's central IT support or a global SharePoint Server administrator who possesses top-level administrative access to the local environment.
