Body (from Message Center)

Updated October 3, 2025: This update serves as a reminder that SharePoint Add-Ins will retire and stop working in 6 months from now (April 2, 2026).

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 app 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.

[What you need to do to prepare]

You will want to notify your Add-In users and developers. Update your user training and prepare your help desk.

For admins

New: How to disable SharePoint Add-Ins on your tenant

Admins can disable SharePoint Add-Ins with the Set-SPOTenant SharePoint Management Shell PowerShell command.

Connect-SPOService -Url https://<tenant>-admin.sharepoint.com

Set-SPOTenant -IsSharePointAddInsDisabled $true

After SharePoint Add-Ins are disabled, users will not be able to add SharePoint Add-Ins to their sites, and admins cannot add new SharePoint Add-Ins to the tenant and site collection app catalogs. SharePoint Add-Ins already added to sites will stay available and can still be used by the site's users.

New: SharePoint Add-Ins will not be available from the public marketplace

After July 1, 2024, users browsing the public marketplace (AppSource) will see SharePoint Add-In, but if they select Get it now, a message will explain that SharePoint Add-Ins are retired and cannot be added. If you still require a specific SharePoint Add-In, contact the Add-In creator to understand the possible options.
