Third-Generation File Sharing, Link Governance, and Expiration Rules

Microsoft is simplifying how users generate and manage URLs across Microsoft 365.

The new hero link sharing experience introduces a single, primary link for every file and folder stored in SharePoint Online and OneDrive for Business. Microsoft calls this update the third generation of file and folder sharing. Rollout runs worldwide across commercial tenants from October through November 2026, requiring zero technical action from end users before it arrives.

Core Architecture and Everyday Benefits

First, understanding how single-link sharing works clarifies its operational benefits for enterprise teams:

• Single primary URL: Every file and folder maintains one persistent sharing link across copying, email sharing, and browser bar URLs.
• Dynamic permission updates: Owners can adjust link access permissions later without generating and redistributing new URLs.
• Unified cross-app rollout: This update standardizes file sharing simultaneously across SharePoint, OneDrive, and Microsoft 365 web apps.
• Conservative default setting: By default, the main link uses “Only people added” access, which grants no immediate permissions until widened.

Admin Controls and Governance Considerations

Second, managing default audiences and legacy link settings requires administrative review:

• PowerShell configuration: Administrators can set the default audience site by site using the DefaultMainLinkScope parameter in SharePoint Online PowerShell.
• No tenant-wide switch: Currently, Microsoft provides no single tenant-wide setting for the default main link scope.
• Link expiration behavior: Existing link expiration policies do not apply automatically to new hero links, so IT teams must evaluate how retention rules apply.
• Legacy link retention: Existing sharing links remain functional and appear under a separate “Other links” tab within the updated dialog.

Action Plan for IT and Helpdesk Teams

To ensure your organization transitions smoothly to updated sharing dialogs, IT leadership should take three steps:

• Evaluate default site settings: Decide whether the default main link audience fits your corporate sharing policy across sensitive sites.
• Audit link expiration policies: Test how tenant expiration rules treat main links to ensure access periods remain secure.
• Update internal training assets: Revise user guides and helpdesk scripts before employees encounter the new sharing interface.
