Thunderbird Community Forum

Some bubble-headed bimbo wiped out the columns inside folders, and deleted the headers - which deleted Thunderbird's ability to choose sorting by date or contact. This f'd it up so BADLY, that I find it USELESS now. I'm going to have to find some other email program.

A 2nd way it was f'd up, is it now seems incapable of importing an existing archive of emails. I tried to do that, and it WIPED OUT the entire archive of "local folders", to create a brand new Local Folder lacking any contents at all. The old stash was DELETED. In the past, I've been able to use this feature of Local Folders, to use the same archive of email between several different OS installations of Thunderbird. Those glory days are gone, thanks to some genius. It seems to have lost the ability to do that.

Really, all this makes me sorry I contributed to Thunderbird, this year. What a waste.

I didn't select to be emailed when somebody answers, because without the sorting I won't be able to notice it happened.

Hi folks, I'm managing a group of users, all using Thunderbird as email clients. I want to disable the users ability to ask for read receipts. I have succeeded to disable read receipt confirmation in a policies.json file, but I also want to block the users from asking for read receipts. I have scanned the different options, but nothing that seems suitable exist.

I would be grateful for help here.

Best regards,

Peter

Greetings, Is there a way to change the order of threads in a folder? The all appear with the oldest message in the thread at the top and new emails that come into that bunch are buried at the bottom with no indication that they are there. I'd like to have the newest entry to the thread at the top and to have the threads with new messages highlighted until the message is read. Possible? Many Thanks

Since a few days, there seems to be an italicized copy of each folder in my mailbox. I tried multiple times to delete them, but, although they seem deleted, they appear again when I start up Thunderbird. I already contacted the hosting service, but they replied that this is an issue of Thunderbird.

I have tried all the recommended methods to alter the display of dates in my Thunderbird inbox but cannot alter the format as short. It is very inconvenient not to see the correct Day number.

Hi! I use Thunderbird at home, but at work I have to use Outlook. This M$ sh... uses Ctrl-Q to mark emails as read. After a long day at work, I go home, sit down at my computer, and automatically keep pressing Ctrl-Q instead of R. I'm sure I'm not alone in having this problem. Could you please allow users to choose which hotkey exits Thunderbird, or at least disable the hotkey?

In reference to the article [[Knowledge Base Article|http://mzl.la/1ApHiU3]], "Move Thunderbird data to a new computer", this misses the transfer of Local Folders.

The instructions only include moving the Thunderbird application data folder with profile information but does not include Local Folders, after completing these instructions the Local Folders will not be present on the new computer.

The path for Local Folders is under Account Settings > Local Folders, this folder needs to be copied to the similar path on the new computer as well.

I have copied emails from a Windows 10 to Windows 11 computer using these instructions and it appears to work.

Only my new Mail is shown in Thunderbird all my Yahoo Sub Folders are MIA. I need to see & have access to those subfolders to a working Email system for me.

The last new email I've received on Thunderbird for one of my accounts was on 5/13/2026 at 12:02 p.m. Every time I open thunderbird it tries to re-download the entire yahoomail account and times out. I have deleted all emails from the yahoo mail box from 5/13 and backwards. All spam emails have been deleted and the trash can has been emptied. Per online instructions I have also deleted the popstate.dat file, tried to repair the inbox file by right clicking on it, going to properties and clicking repair folder. I also tried to compact the folders, and have turned off my virus protection and nothing seems to be working. I also tried a new app generated password from yahoo. Current setup is pop.mail.yahoo.com port 995 SSL/TLS, authentication method = normal password. Any help would be greatly appreciated. Thank you!

I'm having a connectivity issues. Did some searching which directed me to the Appdata Profiles folder. When looking inside I see Mail and ImapMail. Both have numerous folders inside. Too may I believe. Based upon the screen prints of the folder's contents, do you see conflicts?

I have three email addresses with Outlook.com.

Pop.windstream I have not used in many years. Not sure what others I could possible delete.

Thanks.

I want to create a filter to match any of the 20 addresses on my list. Rather than manually repeating the 'add rule' 19 times, I hoped to import all 20 at once.

Creating a filter with 'to' and putting a comma separated list there doesn't seem to work; the addresses won't be matched. I can't find a config file to manually edit in my profile directory for filters, or an extension to create this filter.

My end-goal is to add this 'blacklist' of my old e-mail addresses that have been leaked to a spam filter. These messages already end up in my spam folder by a rule at my provider, but I want to mark them as spam too, so I can sort through the spam folder more easily to find false positives.

Thanks in advance!

I have folders designated A-G, H-Q, etc. and in those folders are subfolders. The A-G folder displays as though it is in Italic font and I cannot move a folder into it.

Wise, a currency transfer business, claim to have sent me several emails as part of a two stage verification process. But they never arrive! They will not accept that the problem is at their end, they say it must be my email programme which is Thunderbird. I have searched everywhere but they aren't to be seen. They say to look in my spam folder but Thunderbird doesn't have one - Thunderbird flags up what it thinks is spam, (usually correctly), but still deliver to my Inbox. Has anybody any suggestions as to what I should do? Until I login, I cannot use my account.
