Microsoft Office 365 for enterprises is a set of cloud-based services, delivered through multiple data centers worldwide. The services are provided through many IP addresses and URLs, listed in this topic.
|All IP addresses listed here are IPv4 addresses, and are supported by Microsoft. If you would like to use IPv6 addresses, learn about the Office 365 IPv6 Program.|
Delivering cloud-based services requires scalable, dynamic solutions that are accessible from anywhere. With these requirements in mind, Microsoft will continue to use new and alternative methods to deliver cloud-based services. To benefit from these changes, we strongly recommend that you enable routing to the root domain names listed in the following tables (such as *.Outlook.com, *.MicrosoftOnline.com and *.SharePoint.com) instead of routing to specific IP address subnets. Relying on IP address subnets runs the risk of outages for your users as changes are made.
This topic contains information that will change over time in order to provide a continued evolution of the services. Periodically refer back to this topic for updates so that you can continue to apply security and routing for your services. |
To see the type of changes that were made to URLs and IP addresses listed in this topic, see Change notification for Office 365 URLs and IP address ranges.
In an urgent situation, we may need to update the services without advance notice and before we can update this topic.
Use these IP addresses and URLs for Office 365.
