Editor’s note 7/31/2017:
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 via PowerShell. After enabling Microsoft Peering, any customer can create route filters to receive BGP route advertisements for Dynamics 365 Customer Engagement applications (formerly known as CRM Online). Customers needing Azure ExpressRoute for Office 365 must obtain 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 trying to create route filters for Office 365 will receive an error message.
Editor’s note 6/6/2016:
Please review our guidance on network connectivity for Office 365 including specific scenarios where ExpressRoute for Office 365 is recommended.
Azure ExpressRoute for Office 365 enables organizations to establish a private, managed network connection to Office 365 as an alternative to connecting over the Internet. This direct connection offers customers more predictable network performance, an SLA for guaranteed availability and additional data privacy. As more organizations depend on Office 365 for document collaboration and communications, they will come to depend more and more on the network connectivity they have between their users and Office 365.
Today we’re pleased to announce that Azure ExpressRoute for Office 365 is now generally available from these network operators:
- British Telecom
- Tata Communications
- TeleCity Group
You can read about how Microsoft is using ExpressRoute for Office 365 in the Microsoft IT white paper, “Optimizing network performance for Microsoft Office 365.”
Connecting your network to Office 365 using Azure ExpressRoute
Depending on your network configuration, here’s how you can work with network operators offering ExpressRoute for Office 365 to establish a connection between your network and Office 365:
- If your organization already uses Azure ExpressRoute, your network operator can simply turn on the connectivity for you. Since use of Office 365 generates additional network traffic, you should discuss the requirements for additional bandwidth with your network operator.
- Organizations using IP VPN technology for a WAN provided by a network operator can ask the network operator to add Office 365 as a node on your WAN. Once Office 365 connectivity is added, Office 365 services appear as if they are on your WAN—like an offsite datacenter.
- ExpressRoute can also support large or point-to-point network connections. If you have a large broad network, then you may already have a network connection in a co-location facility where Azure ExpressRoute is available. You should work with your network provider to identify the best way to connect to Azure ExpressRoute.
