I THINK I HAVE FOUND THE PROBLEM!
I have spotted the detail thats causing it to go into Inbox rather than Junk.
Outlook naturally puts into Junk the emails where the Recipient Emails blank. This has been happening for a while (its super annoying because it fills up my junk and I can’t find emails that should have come to my inbox. I wish they would block emails with a blank recipient!)
BUT what has started happening this week, is if the Recipient email is blank AND the Sender contains “Newsletter@“. So Newsletter seems to be the magic word that allows it into the Inbox.
So if Microsoft could just do a blanket blockade of anything with a blank Recipient, this will completely fix all of my woes.
Im convinced this is the problem, so please support this post so that Microsoft investigates.
Thanks
