Exchange Online IP Addresses

Finding a simple list of IP addresses used by services like Office 365 can be really challenging. Good news for you is I’ve already found them for you. I’ve got a copy of all the IPs (at the time I copied them) plus a link to the Microsoft page where they’re all listed. Enjoy…

as of 2023-08-23 here is the list:
