SharePoint Add-In retirement in Microsoft 365

Since the release of SharePoint Add-Ins in 2013, Microsoft has evolved SharePoint extensibility using SharePoint Framework (SPFx) enabling you to write applications that can be used in Microsoft SharePoint, Viva Connections and Microsoft Teams. With our continued investment in SharePoint Framework, Microsoft is retiring SharePoint Add-Ins.

Key Points:

  • Major: Retirement 
  • Timeline:
    • Starting July 1st, 2024, SharePoint Add-Ins cannot be installed from the public marketplace, also referred to as store by existing tenants. Installation from a private tenant catalog stays possible.
    • Starting November 1st, 2024, new tenants will not be able use SharePoint Add-Ins, regardless of their origin (public marketplace, private tenant catalog).
    • Starting April 2nd, 2026, Microsoft will remove the ability use SharePoint Add-Ins for existing tenants.
  • Action: Review and assess impact

How this will affect your organization

If your organization still uses SharePoint Add-Ins, they will no longer function after April 2nd, 2026. We recommend customers to port their customizations to SharePoint Framework (SPFx) and ask their solution vendors for updated solutions.
