Additional Domain Whitelisting Required for Microsoft Whiteboard [MC1150679]

Message ID: MC1150679

Introduction

To maintain uninterrupted access to Microsoft Whiteboard, organizations using explicit domain whitelisting must update their firewall configurations. This change supports backend service operations as part of Microsoft’s One Consolidated Domain Initiative (OCDI).

When this will happen

This change is effective immediately. We recommend updating your firewall rules as soon as possible to avoid service disruptions.

How this affects your organization

Microsoft Whiteboard has transitioned to the cloud.microsoft domain under OCDI. While many tenants have already whitelisted *.cloud.microsoft, some organizations using explicit domain whitelisting have only added whiteboard.cloud.microsoft.

To ensure full functionality, including backend service operations, the following domain must also be whitelisted:

• whiteboard.svc.cloud.microsoft

Failure to include this domain may result in issues with Whiteboard loading or sharing features. This has been confirmed in multiple support cases where backend calls were blocked by firewall rules.

What you can do to prepare

If your organization uses explicit domain whitelisting, please ensure the following domains are allowed:

• whiteboard.cloud.microsoft
• whiteboard.svc.cloud.microsoft

Compliance Considerations

No compliance considerations identified, review as appropriate for your organization.
