Thanks for confirming this Sven. I took your advice and found out that according to fastcompany website, the app stores messages on third party servers and sends password information back to microsoft (annotated source: https://genius.it/14327807/www.fastcompany.com/3042238/microsofts-new-outloo...)
I spotted a couple other IP addresses that also belong to them and are used to access my users mailboxes (and possiblty passwords !)

Could it be that the outlook app uses microsoft's servers to fetch the

Yes, this is the case. Have a little web search for "microsoft outlook
app security risk" to see the implications.
