Since earlier today, the Junk filter keeps sending all emails received (from a microsoft email server) directly to the Junk folder, even when I turn it off.

I have this new behavior (all incoming emails going to the Junk folder, even when I move these back to the inbox; and even when having the junk function off in settings for that account) since earlier today (about an hour ago). I never had this behavior before with this email (or any other; and my other emails are showing no such behavior). I have been using Thunderbird for years. That particular email is handled by Microsoft. outlook.office365.com (IMAP, port 143)

Anyone aware of any changes happening today? (April 29, 2020) with outlook emails fed to Thunderbird?

Cheers, FFL

My guess is that office is marking it as spam, not Thunderbird. That would account for it happening when Thunderbird's junk filtering is disabled. So anti virus/internet security products interfere in this space as well. Does your have a spam filtering option or a scam tool?

Thank you.

I had to turn off junk mail filtering on the original outlook service. So something was changed from Outlook's side, but I do not know what yet. I will now have to rely on only Thunderbird's junk filtering. Best FFL
