Remove/ Undo Ignore Thread on deleted email

Question

My thunderbird had a spaz out recently, and it seemed to do three things:

1. placed an "Ignore thread" on an email
2. deleted said email
3. created an archive folder in my inbox

This happened while I was attempting to write an email, and the draft became non-responsive without me knowing, and while I was typing, it seemed to take my input as command prompts/shortcut inputs? So now, I cannot see any new emails related to the one that was deleted.

For a while, there was a prompt to "Undo Ignore Thread", but pressing the button did nothing. I pressed it several times, and waited, to no avail. I ended up resetting Thunderbird, and the prompt disappeared.

I have since received new emails, and it says that I have 1 unread email, but I can't find it anywhere in my inbox, or any of the subfolders.

Answer 1

So, luckily, in my case the message hadn't been deleted, only hidden.

There's an option to choose whether or not you want to see ignored threads. Select the folder (in my case, the Inbox), then go to View > Threads > Ignore Threads

This will show all threads you have chosen to ignore. To undo this, select the message you have placed the ignore on, then go to Message > Ignore Thread. Refresh the folder, and all following emails will appear.
