| MC1113112 | (Updated) Microsoft Exchange Online | Releasing Multi-Geo In-Region Routing | In-Region Routing (IRR) is disabled by default. If you do not plan to use this feature, no action is required. For domains where you choose to enable IRR, the feature allows you to route inbound emails to accepted domains associated with specific geo-regions. When these domains are aligned with users located in the same geo-region, emails are fully processed and stored within the recipient's region. This ensures that data remains within the user's Preferred Data Location (PDL), supporting stronger data sovereignty and compliance with regional regulations. If your organization uses Microsoft Purview capabilities such as Data Loss Prevention (DLP), retention policies, or eDiscovery, you may need to review and adjust those policies to ensure they align with the new regional routing behavior. |
