I was having this same issue and your advice helped me. Thank you.
This is such a wasteful shame to need to do this silly work-around. My Windows 11 pc was using the "old" Outlook app and I decided to use the "New" Outlook app. No problems setting up all of my email addresses when I had originally set them up on the "old" Outlook app. The "New" Outlook app was giving me so many issues.
