Hi Scott,
It sounds like you are able to configure Outlook on your Mac to connect to your on-premises Exchange server without any issues, but encountering difficulties when trying to do the same on Windows with the latest version of Outlook.

Here are a few potential solutions you can try:
1. Verify network connectivity: Ensure that your Windows machine has proper network connectivity to reach the on-premises Exchange server. You can try accessing the server using other applications (such as a web browser) to check if there are any network restrictions or firewall settings blocking Outlook's connection.
2. Check Outlook...
