What needs to be allowed through web proxy to run Hybrid Configuration Wizard?

Iron Contributor

We are migrating our Exchange management server for hybrid to a new server.

The new server has internet access blocked and needs to go through a proxy.  What are the URLs and IP addresses that are required to be allowed outbound through the proxy and firewalls to successfully run the Hybrid Configuration Wizard and get the new server set up?


There are no on premises mailboxes.

The new server is at a different physical location and will have a different host name and IP address.
