Office 365 Whitelist URLs for Firewalls & Trusted Sites

By Chris Blackburn

With the ever growing list of Microsoft Office 365 services comes a growing number of URLs to whitelist on web application firewalls, proxies, and IE trusted sites lists. The full list, which can be found at https://support.office.com/en-us/article/Office-365-URLs-and-IP-address-ranges-8548a211-3fe7-47cb-abb1-355ea5aa88a2, is quite intensive and for my own sake (and that of my clients) I’ve created the abbreviated list below to save not only the community but myself some time!
