Microsoft 365: Multi-Geo In-Region Routing

🚨 The Signal: Multi-Geo In-Region Routing allows organisations to specify the geo-region for inbound email routing for accepted domains. This enhances data residency controls for email, aligning with sovereignty requirements.

The Impact

Security teams and compliance officers are affected by enhanced data residency controls for email, reducing data sovereignty risks.

• Compliance officers: Improved ability to meet data residency obligations.
• Security teams: Enhanced control over email data location, reducing sovereignty risk.
• Legal teams: Better assurance of data location for regulatory compliance.
• IT architects: New configuration options for email flow and data placement.

The Action

1. Review existing Multi-Geo configurations for Exchange Online.
2. Identify accepted domains requiring specific in-region routing.
3. Configure In-Region Routing for relevant accepted domains via Exchange Online PowerShell.
4. Validate email flow to ensure correct geo-routing.
