Office 365 and huge list of proxy exceptions

Hello,

we are migrating to Office 365 including the migration from on premise to online Exchange.

I found this thread:

https://community.sophos.com/utm-firewall/f/general-discussion/101289/office365-deployment-best-practice

Since the last entry is years ago, are there any new solutions for the problem of maintaining these huge lists of exceptions?

It looks like the scripts aren't working anymore.

I think I need days of inserting all these ips, subnets and urls just once. And there may be many typos.

This is a little annoying, since this is the final step towards office 365 and it is such a blocker.
