Don’t use “Outlook (new)” in #Windows 11. I just did a tcpdump and looked also at my #mail servers when setting up an account in there. The mail client only spoke with Microsoft-servers, never with my mail-servers and I saw on my mail-servers only connections from Microsoft-IPs.

Better yet, don't use ANY Micro$haft product. There are two basic choices, Mac or Linux. Using Gatesware at all is a fundamental error.
