End of Life for Lightning Link with effect from April 2026
Beginning April 2026, the Skyhigh CASB Lightning Link capability will reach its End-of-Life as we execute on the Delta API initiative.
Customer Impact
Customer Impact
- Effective April 2026, when Microsoft deprecates the legacy SharePoint API stack, the Lightning Link functionality will stop working.
- With Microsoft moving away from the old SharePoint Web app to Graph APIs, the Lightning Link feature [requiring push notifications] won't work with the new Delta API Pipeline powered by Graph API.
- If you're already a Skyhigh for Microsoft 365 customer, you can still use Lightning Link until April 2026. NRT DLP will work with the new Graph APIs once you switch to Delta API, and Lightning Link will keep using the SharePoint Web App.
Deprecation Notice
- Documentation has been updated to reflect the change
- Migration to Delta API - FAQ Section
- Lightning Link Section
