What are the FQDNs used for Office 365 logon and authentication?

I mentioned that in my original post, quote "I found this list https://learn.microsoft.com/en-us/microsoft-365/enterprise/urls-and-ip-address-ranges?view=o365-worldwide of all URLs and IPs that Microsoft tries to use for Office 365, and I tried adding"

That link, in the word here, goes to that post you mentioned. Did you read my original post, or click the link?

That is a huge list though. I only want URLs that pertain to authentication for Office 365. Not random stuff to make skype, onedrive sync, etc work.
