Dear AnywhereNow Customers and Partners

Microsoft has announced the retirement of the Client ID/Secret authentication method for SharePoint Online in April 2026, which has historically been used to connect to SharePoint. This change is part of Microsoft’s deprecation of Azure Access Control Services (AACS). For more details, see the official Microsoft announcement: https://aka.ms/retirement/acs/support.

Timeline and Impact
As per Microsoft Message Center announcement MC693863 (November 27, 2023):
November 1, 2024: New tenants can no longer use SharePoint ACS.
April 2, 2026: ACS will be fully retired; existing tenants must migrate by this date.


What does this mean for the Dialogue Cloud Platform?
After April 2026, the Client ID/Secret method will no longer work to connect the Dialogue Cloud platform with your SharePoint sites.


What is AnywhereNow changing?
To align with Microsoft’s security standards and roadmap, AnywhereNow is transitioning to certificate-based authentication for SharePoint Online integrations. This approach enhances security and ensures long-term compatibility with Microsoft 365 services.

Action Required:
Before April 2026, please change your UCC site authentication method to using AppOnly/Certificate as advised by both Microsoft and AnywhereNow.

For detailed guidance, refer to:
https://golive.anywhere.now/platform_elements/sptemplate/additionalconfiguration/sptemplate-from-appclientsecret-to-appcertificate.html


What happens if no action is taken?
If the migration to certificate-based authentication is not completed before April 2026, your applications will lose access to SharePoint Online, leading to critical service disruptions.
• UCCs will fail to start after a restart, causing an outage,
• Call recordings will not be saved in SharePoint.
• IVR or agent list changes will not take effect.
• Callbacks and voicemails will not work.
