Customer Action Needed by April 2, 2026 - Certificate Based Authentication
In progress - Scheduled maintenance is currently in progress. We will provide updates as necessary.
Feb 26, 2026 - 19:15 UTC
Scheduled - Cohesity is issuing this advisory to inform our Cloud Protection Service (CPS) customers of an important change regarding authentication for Microsoft 365 workflows. Microsoft is retiring Azure Access Control Service (ACS), effective April 2, 2026. Currently, ACS is utilized for authentication in certain Microsoft 365 workflows, including backups for SharePoint, OneDrive, Teams, and Groups.

After April 2, 2026, backups for these protection jobs will fail unless customers migrate to Certificate-Based Authentication (CBA). To ensure uninterrupted service and data protection, we strongly recommend that all customers review the provided Knowledge Base (KB) article and follow the migration instructions.

This impacts all regions and all CCS customers.

Recommended Action:

All recipients of this Field Notice are advised to review the KB article from the additional Resources section for detailed information and recommended preventive actions.
