Microsoft changed how the Microsoft Peering routing domain is reviewed for Azure ExpressRoute. Starting July 31, 2017, all Azure ExpressRoute customers can enable Microsoft Peering directly from the Azure Administrative console or through PowerShell. After enabling Microsoft Peering, any customer can create route filters to receive Border Gateway Protocol (BGP) route advertisements for Dynamics 365 Customer Engagement applications (formerly known as CRM Online).
Customers who need Azure ExpressRoute for Office 365 must request a review from Microsoft before they can create route filters for Office 365. Please contact your Microsoft account team to learn about how to request a review for enabling Office 365 ExpressRoute. Unauthorized subscriptions that try to create route filters for Office 365 will receive an error message.
