SharePoint Online URLs and IP Addresses

IT administrators might want to control communication to specific SharePoint Online sites through an on-premises firewall. To do this, you’ll need to know the IP address ranges used by SharePoint Online.

Outgoing IP Address Ranges

Ports in your on-premises firewall might need to be opened to accept network traffic originating from Microsoft Datacenter IP addresses. SharePoint Online accepts inbound connections through the browser using the HTTP or HTTPS protocols over ports 80 and 443 and makes outbound connections on port 25 (SMTP). The IP address ranges used by SharePoint Online are listed below. Note that because Project Online is a SharePoint Online service, these IP address ranges also apply to Project Online:

Note    If you see issues after successfully setting up firewall ports, please check for updates to the IP values in this article.
