Emails to Outlook delivered to Junk Email folder with SCL 1
The move to Junk folder might be performed by Outlook's antispam engine, not EOP. A quick way to verify this is to check the "info bar" - it will tell you who marked the message as Junk. Or run a message trace - if It was marked by EOP, it will be reflected there.
Here's an easy to follow article on that: https://www.slipstick.com/outlook/rules/moved-message-junk-email-folder/
It can also be due to custom Junk threshold, as detailed for example here: https://support.microsoft.com/en-za/help/3019725/how-to-troubleshoot-unexpected-junk-email-behavior-in-office-365-dedic
The "info bar" shows 'This message was identified as spam. We'll delete it after 10 days'
Would this suggest that it was EOP? I didn't think that Outlook.com had it's own Anti-Spam engine - I thought that EOP served that purpose.
Your second link refers to Office 365 which is a slightly different platform that Outlook.com so am I to assume the content of that KB doesn't apply?
