We actually contacted the user and asked. Their story goes like this:

Yesterday they were looking for an email from us, which was supposed to
arrive yesterday (it was a contract renewal). It was not on their inbox,
so they used search to find all emails from us and last year's email
came up. So they clicked on last year's email and opened it. They did
not report it as spam yesterday, they only viewed it. They don't use an
email client, they only use the web interface provided by hotmail.

So it's not bulk moving emails to junk using imap. Opening the email
yesterday triggered the fbl process somehow.

I'm still not quite certain of how it works, but Mihai Costea also
posted that 1% of their fbl reports are back from 2016 ...

[mailop] Hotmail/Outlook feedback loop processing delay?

[Sotiris Tsimbonis]

Hi all,

I received today (9 Jan 2018) a message from outlook's feedback loop
with a message that was originally sent to a hotmail address on 30 Jan 2017.

Can someone explain why I've received it so late, almost a year after it
was sent?

Is it because the hotmail user marked it as spam today?
Did the hotmail user mark it as spam earlier but was processed by
hotmail today?
Did the user do nothing, but hotmail's own processing classified it as
spam almost a year after it was received?
Something else?

Kind regards,
Sotiris.
