SharePoint Designer 2013 loses all support on 14 July
Reviewed by Helen Jones
Microsoft will end support for SharePoint Designer 2013 on 14 July 2026 under its Fixed Lifecycle Policy, with no extensions. The tool was used for years to build and edit classic SharePoint workflows. SharePoint 2013 workflows themselves were already fully retired for existing Microsoft 365 tenants on 2 April 2026. On-premises SharePoint Server can still run them if Workflow Manager stays up, but Microsoft will provide no security updates, bug fixes, or technical support after the July date. Microsoft is directing organisations to move remaining processes to Power Automate. Built-in migration help is limited, so most workflows will need to be rebuilt rather than converted automatically.
Until now many teams could leave older Designer workflows running in the background while they experimented with Power Automate on new processes. The authoring tool still opened, lists still triggered, and IT could patch problems if something broke. That buffer is gone. Any process still sitting on Designer is now on a hard clock, and the people asked to rebuild it are often the same non-developers who already wrestle with missing dynamic content, approval stages, and silent failed runs. The migration pressure lands exactly where reliability habits are weakest.
Analysis
This is a change to act on, not a trend to watch. Open your main SharePoint sites, list every remaining 2013 workflow that colleagues still depend on, and rebuild only those critical ones in Power Automate with a clear owner, a Teams or email alert on failure, and a simple rejection or timeout path before the July deadline.
