I too have been with Outlook/Microsoft for over 20 years. The the last 10 years as an insider, in a professional network admin. and consultant manner. I can't fix this problem, either. The only mail that goes to junk, which I don't want to go to junk is from my bank. It started a few months ago and regardless of what I do, it simply goes to junk. I have even "reset" the app, uninstalled, reinstalled, reset junk settings, cleared blacklist and whitelist and rebuilt both lists. Nothing fixes this. It occurs in the Outlook 365 app and web app. I will no longer subscribe to 365 after this, as I have a professional copy of Office 2021, and will just use that until it crumbles to dust. With the disaster that is Windows 11 and "subscribe for life paradigm" that Microsoft is moving to, it is time to bid them farewell. There is a whole other world out there where software just works, isn't bloated, isn't tied to oligarch shareholders, and where the community is the tech support and doesn't copy and paste from a corporate-approved script.
