Notes & Warnings

Important If enabling the Office 365 proxy bypass setting described in this article, ensure you have appropriate firewall rules in place. With this setting enabled, traffic to Microsoft Office 365 services will be routed directly, and will not be subject to inspection by the cloud service. Fore more information on the URLs and IP address ranges required for access to Office 365 services, see the following Microsoft article: https://docs.microsoft.com/en-us/office365/enterprise/urls-and-ip-address-ranges

Note: If Office 365 is bypassed, it will prevent you from performing Office 365 tenant restriction using custom headers inserted by the cloud proxy. See Restrict users to specific Office 365 Tenants for more details.
