I have Office 365. From our systems I get an automated email every morning with system statistics from the day before. I have been receiving this email for years.
Every so often, Exchange 365 decides it's 'Clutter', and puts it in that folder. Every day, I tell it that it isn't clutter, and have it moved back to my Inbox.
After a couple of weeks of Exchange refusing to learn this simple fact, the email disappeared from 'Clutter' and from Inbox. I eventually found it in 'Junk Email'. I have now reported it several times as 'Not Junk' but it still puts the email in the Junk folder.
Needless to say, the email comes from the same domain as it is delivered to.
