Some Junk Mail (so far, only from my Outlook mail account) is appearing in my Inbox. This mail has a yellow banner at the top stating "Thunderbird thinks this message is Junk mail". Also on this banner is a button marked "Not Junk", that allows me to tell Thunderbird that it is not Junk. At the very top of the message (as with all messages) is a button marked "Junk", which in this case is "greyed out" and so won't work, although this button is not greyed out for messages that are not thought to be Junk!. This seems counter intuitive to me. Thunderbird is allowing some messages into the Inbox which it thinks are Junk, but disables the button that allows me to confirm it! I know that I can still mark the message as Junk by using the individual menu for the message (3 vertical dots), but why disallow the obvious "quick action" button?
