Thunderbird Community Forum

I have been shifting my email platform from Comcast to the new Yahoo platform. This has worked for my iPhone and for my Thunderbird app on my iMac. But NOTHING works for this on my MacBook Air. My gmail is fine, but the only way I can get to my new Yahoo platform is to sign in via the web browser. Thunderbird will not configure for the MacBook Air, and I've tried 10-15 different things already (not an expert by any means). I have all the proper settings. I have reinstalled Thunderbird on the latter machine.

Does resetting your primary password in Thunderbird only delete the usernames and passwords in Thunderbird or does it also delete the usernames and passwords in Firefox?

Thunderbird just updated and the next time I opened it all of the folders I created and the emails I'm storing within them are missing. I found my profile as directed. I'm not sure if I have a backup of it. I've included the screenshot as you ask for. I know that those folders and emails are there as I was playing around with the the 3 lines > View and when I moved between the different choices I saw my folders/emails are all in there.

Any assistance you can provide is appreciated!

I have just installed Thunderbird on a replacement computer (running Linux Mint). The version I have is 140.7.1esr. I use a POP Gmail account. For a change it installed and connected seamlessly, but I cannot persuade it to download anything other than the messages in my Inbox. I have right clicked as recommended on my Gmail address, but see no 'Subscribe' to select. What am I doing wrong?

TB suddenly moves messages from inbox to trash automatically without any interaction. Search through the forrum shows that it has been asked for already, see https://support.mozilla.org/en-US/questions/1588804, similar postings can also be found with you search engine.

As described in other postings, the messages are moved from Inbox to trash. When moving them back manually from trash to inbox, they are moved to trash again immediately.

• it happens for the default account only,
• there're no filters at all in TB,
• junk detection is disabled,
• Settings->General Storage is all disabled,
• (account)->Settings->Server Settings has checked "move deleted messages to trash",
• (account)->Settings->Storage is all disabled,
• Inbox->Properties "Repair folder" does not help,
• Inbox->Properties "rules is set to "use account settings" (and greyd out "do not delete messages"),
• exactly same behaviour when starting TB in save mode,
• manually deleting all *.msf files (for inbox) does not help,
• manually deleting xulstore.json does not help,

Additional notes, which are not related to the problem, IMHO:

• IMAP on port 993,
• no other clients anywhere are connected to that account,
• TB configured for more than 10 accounts, more than 500 folders and sub-folders,
• host with > 16GB RAM, TB uses 3GB virt,
• problem observerd in older TB also, at least 13x.x

I'd be happy to debug/trace the problem if someone can give me detailled insructions how to start TB with debugging. Please feel free to ask for about:config settings as they are non-ambiguous and language independent ;-)

Thanks.

I put emails from my Inbox into the delete box. After a while I delete these but I have just found that they remail in the All Mail Box. How do I delete these emails from my acccount on Thunderbird? They do appear in my online Gmail account as far as I can see.

I'm running TB on Windows 11 on a Dell Desktop machine. It's a pretty basic installation with EE Cyber security, which is I think Norton. I've been using TB for a couple of years but recently it has almost stopped working. I notice from Task Manager that TB is massively leaking memory and consuming much CPU time. I don't think I have any add-ons and I only use TB for email. It's now so bad that I'm even unable to go into TB's Settings or Tools or anything else. I've tried creating an exclusion for TB profiles and TB.exe in the Norton. I've tried starting TB in troubleshoot mode but all to no avail. I have it in IMAP, Port 993, SSL/TLS for incoming mail and Port 465, SSL/TLS, Authentication Required for Outgoing mail. I'm currently often unable to even access mail previously downloaded to the local Mail folders, TB is just hanging with the bar in the lower right corner endlessly running along. Most puzzling of all, is that very occasionally is starts working again and then I dare not switch the machine off! It's become an indeterminate system. Please help, I'm nearly eighty and trying to organize my holiday, which is needs email to make bookings. Thanks in anticipation.

Enclosed are jpg copies of the current sets of filters failures in my TB email program.

TB Error0 shows the 6 emails that have arrived and are placed in the INBOX. However, each of these has a corresponding filter set up to move them upon arrival to a separate subject email mailbox.

Note: If I highlight the INBOX and then go to Tools > Run Filters On Folder ... all of these INBOX email messages will be correctly filtered and moved to their respective email mailbox, BUT each of them is shown as having been "read" and unless you pay close attention, you may not know where these INBOX emails were sent.

I am also enclosing TB Error1 & 2 that show the last couple of days message filtering errors.

I can find nothing wrong with how each of these filters are set up, yet they seem to consistently fail to operate when new emails arrive.

Note one of them is for incoming emails from ... schiffsovereign.com. I have edited this filter repeatedly, even deleted it and re-input the information. Yet the filter never takes hold and does what it is designed to do. I am enclosing a jpg of that specific filter as TB Error3

I am looking for suggestions on how to fix this problem.

Thank you and best wishes,

I've successfully connected to a hosted Exchange server through EWS and NTLM authentication (kudos BTW). But there is a problem - often during operations against EWS I'm presented with "Login to account XXX failed" "Login to server YYY with account XXX failed". I can ignore it (cancel) and it will work for seconds or minutes but eventually reappear. Sometimes it's very frequent, sometimes is here and there. TL;DR; connection works, I can read directories and e-mails.

From looking at development tools I see these scenarios: 1. POST requests return 200 always (no messsage of course) 2. Eventually a POST would return 401. Then Thunderbird issues a GET, it returns 401 as well but response includes header WWW-Authenticate: NTLM XXXXXX. Then another GET is issued containing header "Authorization" with the value from previous response. This time it gets 200 and continues without POST requests without a dialog. 3. Sometimes there are more POST requests with 401 (I assume in parallel) before a GET is issued and then I see a dialog. Sometimes it recovers (regardless of whether I cancel or retry), sometimes gets stuck with 401 with dialog reappearing each time it tries something. This case it's similar in sense that thunderbird issues GET with 401 and WWW-Authenticate header, issues another GET with Authenticate header but still gets 401.

If I had to guess I'd say the problem happens when POST requests are issued in parallel, not sequentially. OTOH it might be a problem at the server, but it isn't very likely.

Within the past day or so, which means 7-18-26 or later, some of my email messages on thunderbird for my pc have a "From" description that is not correct. I look at the messages, and the "From" is entirely different than the "From" description when looking at the email message list. I have never encountered this problem before. I'm using thunderbird 152.0.1 64-bit on my pc.

Need help to stop that. Don't need it on receipts or email notes I want to save as PDF files. Very frustrating no matter what I have tried. Dell XPS 8940 desktop win 11 Pro 32 GB RAM Appreciate any help...scanned files but didn't turn up this issue.

Been struggling to get any of the 4 different accounts from PennTeleData at my body shop to connect to thunderbird. They were working yesterday and all of a sudden no good this AM. I can access my PTD email through their web browser and they don't have any support for a 3rd party program. Sure wish there was someone to call at mozilla. I have exhausted soooo many different options all to no avail. Any advice or questions for me to better let you know what my issue is?

I have two domain accounts; crumpcorp.com and dannycrump.com with GoDaddy. I have two E-mail accounts; [redacted] @crumpcorp.com and [redacted] @dannycrump.com. I use Thunderbird desktop Email. Thunderbird has the ability of use filters to perform automatic actions on messages received. One of the filters is “Forward Message To”. Unfortunately, attempting to forward messages fails. Thunderbird displays the following message:

Sending of the message failed. An error occurred while sending mail. The mail server responded: Request failed; Mailbox unavailable. Please verify that your email address is correct in your account settings and try again.

Please help with this issue.

Please respond to [redacted from community support forum] @dannycrump.com

I just had to reinstall Thunderbird on my computer. Somehow after being away for a year and firing up my computer Thunderbird advised best to reinstall. I was able to get some of my contacts but not all. Thought it would be simple to just export my Thunderbird address files from my Windows laptop and import it to my Thunderbird app on my windows computer. Seems obvious and simple but not so for me. The suggested solutions do not work. Am I missing something?

Can not get my password to be accepted. Since I am on this page I know the email address is correct Do You have an idea how You can get Me a phone number to ask for help? O don't want to list a number here to call since I might have been scammed and fear the number would be fake callback..

I need a filter on a message to FULLY FINISH before a next message starts to be filtered. The "help" (quotes because it's an abyssal crap) says that simply ending the filter with Stop Filter Execution does it - but that's simply NOT TRUE: calling a console program in the filter, I can see five DOS boxes opening at the same time with five messages matching, i.e. the filters on the next message DID NOT wait! So... what can I do??

All of the above is because I'm getting "Too many simultaneous connections on the server". I'd like to limit the concurrency, but it only seems to be possible in IMAP, while this connection is a POP. Why only IMAP??!
