No. not unless you had a backup. Filter rules are stored within the mail account folder.

Yahoo are being a real pain. They are advising people to delete their mail accounts when all they need to do is access the Account Settings for the yahoo account and change the incoming and outgoing server smtp settings for Authentication Method to OAuth2. Then restart Thunderbird to get the yahoo prompt to set up oauth token.

Anyone know how to post a new question in the Thunderbird support question? I can't seem to find the start new thread option.

Thanks

Thank you @Toad-Hall , yes I agree they've been a pain, it's not the end of the world, I can set up new rules as and when appropriate emails come in. At least I now know there's a short cut for my wife's account.

I just wondered if there might be some lingering trace of the old rules in a profile folder somewhere.

Filters are stored in the msgFilterRules.dat file in each account subfolder of Mail or ImapMail, e.g. ImapMail\imap.mail.yahoo.com, and can be copied between accounts or from an old profile folder to a new one, with TB closed.

@sfhowes , You sir, are only a flipping genius!!!

MikeZZ From Thunderbird Help > Thunderbird Help Then scroll down and click on 'Ask the community' Select 'Thunderbird' Top right 'Ask the community' - click on 'ask now'

If in a forum question At the top of page click on 'get Help' and then select click on 'Ask the community' Select 'Thunderbird' Top right 'Ask the community' - click on 'ask now'

Thanks Todd, I tried from a forum question from Firefox 77.0.1 and there was no 'Ask the community' on the top right. See the attached screenshot

From within Thunderbird it does work as you described

The image shows you looking at a question, so obviously, at that point in time, you had not even started to follow any of the instructions.

You need to hover the mouse over the words 'Get Help' which is visible at the top, then you would get a large drop down in which you would see and need to click on 'Ask the community' Then you would select 'Thunderbird' and at that point you would get 'Ask the community' on the top right, where you can select 'Ask Now'.

I see what I did wrong. When I hovered 'Get Help' I saw 5 Firefox options and 'browse all product forums', clicked that and selected Thunderbird. This leads back to the questions.

Ask the community needed to be clicked first.

Thanks
