Microsoft is retiring the SharePoint Add‑In app model as part of a global rollout. The official retirement date is April 2, 2026, but tenants will experience the change at different times depending on Microsoft’s deployment schedule.
When your tenant is affected, clicking the Nintex Workflow or Nintex Forms Add‑In will show a generic Microsoft message indicating that the service is no longer available. This is expected behavior and is not specific to Nintex.
What this means for you
Nintex Workflow for Office 365 Add‑In
Workflows created in the Nintex Workflow Add‑In will stop running once Microsoft disables the Add‑In model in your tenant.

Nintex Forms for Office 365 Add‑In
Forms created using the Nintex Forms Add‑In will no longer open. Any forms you need to continue using in SharePoint Online must be migrated or rebuilt using SPFx.
