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:

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.
