Changing authentication method affect on existing jobs

[HangTen]

How does changing authentication method (from basic to modern) affect the existing backups? I have read this article: https://www.veeam.com/blog/office-365-b ... te-4c.html. I was wondering if there is a more up to date document in case Microsoft has addressed some of these limitations.

Veeam has a KB page about the limitation.
This page should be up to date:

It looks like the same limitation from your blog post

Mildur is correct, and no, those limitations remain I'm afraid
