When we went through this over a year ago, and I believe we had to provide Microsoft IP addresses that they should expect to see traffic from when leaving our network.
Likewise, the on-premise hub servers had to be configured to allow connections from certain Office365 address ranges. We encountered a hiccup because we were doing SNAT on the LTM and the hub servers weren't trusting the SNAT address we were using, so we had to add it in as a connector.
We also started with just one hub server to get things working and then added others after getting one working. Keep it simple to start with.
