To help ensure that network traffic from Microsoft datacenters is accepted, you may need to open ports in your on-premises firewall so network traffic originating from IP addresses in the datacenters can enter your on-premises organization.

Microsoft Office 365 relies on third-party content caching engines to achieve good performance and response times. The types of content cached with these third parties are non-SSL resources, such as the images downloaded to draw the Outlook Web App user interface. As stated above, it's possible and supported to use IP-based filtering for the SSL content downloaded from Office 365 and for the Office 365 end-points that make in-bound calls to an on-premises environment. However, it isn’t possible or supported to use IP-based filtering for the non-SSL resources hosted on third-party content caching engines. To express filtering rules that allow those non-SSL resources to be downloaded to clients on your intranet, you need to use hostname-based filtering (as opposed to IP-based filtering). This is because the IPs used by the third-party content caching engines change frequently in a manner which makes it impractical to track each individual IP change. Allow the following hostnames for these non-SSL resources:
r3.res.outlook.com
r4.res.outlook.com
xsi.outlook.com
prod.msocdn.com
*.mail.onmicrosoft.com
