This is still the official list:

MS provides this enormous list of IPs and subnets in some crazy format or XML. I counted 343 entries!!! Do they really know, they need all of these?!

Seems to be more secure, to use a list of FQDNs. But how can I use FQDNs with wildcards like *.office365.com to alias and use them in the pfSense firewall rule set?

I found one posting, someone used Robtex.com to translate a much shorter list into IPs. But that seems not feasible by sheer amount.
Any suggestions?

You can't. If you want to know why, research how a domain alias works.
