Some organizations have policies that require inbound/outbound filtering to internet services such as Microsoft Office 365 for enterprises. As with most global high traffic web applications, listing all of the connection points to filter is a near impossible task. The connection points span many Microsoft datacenters worldwide and include the use of internal and 3rd party Content Delivery Networks (CDNs) to host graphics and other parts of the service. Using CDNs for HTTP & HTTPS traffic is an industry standard for web based applications enabling better performance, faster response times, and the ability to deliver enhanced end user experiences. Currently those enhanced experiences are available for our browser based tools (such as the Admin Portal, OWA, etc.). Although this may change in the future, the non-browser based tools (such as Outlook, ActiveSync clients, Lync, etc.) are not currently optimized to use the CDNs.

Considering the changing nature of our datacenters and the CDNs, we recommend moving away from inbound/outbound filtering, especially if the browser based tools will be a central component of your deployment. If the browser based tools will not be a part of your deployment strategy and only the non-browser tools will be used, filtering based on URLs (such as *.Outlook.com, *.MicrosoftOnline.com, *.SharePoint.com, etc.) will offer a reliable connection experience and filtering based on IP addresses will offer a reliable experience that requires maintenance when we add new IP address ranges.

If you still need to manage inbound/outbound filtering for the non-browser based clients, we maintain the list of URLs and IP addresses in this article and the associated articles for each service. We make a strong effort to update the list after we make changes to our production systems. We can’t guarantee that we will always support connectivity to the IP addresses from non-browser based clients and recommend you evaluate moving to URL based filtering in the future. If you want to see just the changes, we keep those with date stamps in the Change notification for Office 365 URLs and IP address ranges article. You should Subscribe to the RSS feed of these changes to ensure you are notified of changes.

The URLs and IPs below are for all Office 365 subscriptions regardless of which services are included in the subscription. To successfully manage inbound/outbound filtering, you need to include the URLs and IPs below as well as the URLs and IPs for each service included in your subscription. For URL and IP information of each of the services we have linked directly to those pages.
