Thunderbird Support Forum

This issue shows up randomly, affecting a random number of messages. Issue is that one message will take over other messages following. Message notification will look normal in the inbox, but click on the message following X message, and the X message is what will appear. The subject line at the very top of the page will be from Y, but the rest of the information following will be from X. Two, three or more messages may be affected. Deleting X will make no difference. This time, four messages were affected.

Steps to reproduce:

Nothing! I walk away from Mac at night. When I come back in the morning, all of my normal apps are available and running fine (including Firefox). However, Thunderbird is unresponsive. Clicks aren't recognize. However, I can quit it and relaunch with it normally operational.

Actual results:

Thunderbird was unresponsive.

Expected results:

This shouldn't happen at all.

I have two email accounts. On the first one I cannot send or receive emails. I get message "login in to server imap.telstra.com with username *******@bigpond.net.au failed."

On the second I am receiving and sending emails but it is not saving my sent emails.

Any suggestions?

My Thunderbird email works perfectly when the PC is connected to a network by WiFi or cable. But when I connect the PC to the internet via the 'Personal Hotspot' (shared internet) function on my iPhone, I can only receive emails, not send emails. See attached screenshots of the error message and account settings. I use Thunderbird version 91.9.0 (64-bit), and Windows 11 Home version 21H2. Windows Security for antivirus and firewall. Mail provider is domeneshop.no.

hey all, I hope you can help! Thanks in advance.

Thunderbird crashes and hangs up many times every day. I am using a macbook pro, OS Monterey, 12.3.1 and Thunderbird 91.9.0 (64-bit).

When I try and submit the crash report I get an error page on submit that reads "Bad Request (400)". Trying this short thing in case the problem is how long that is ...

I just switched over to Thunderbird after seeing so many people saying it's the gold standard and I am having nothing but headaches with it so far. Hopefully it's just my computer illiteracy that's the problem. Any help would be MUCH appreciated!

The first I'm facing is that emails I open (and even respond to) keep automatically marking themselves as unread. It generally happens several seconds after I click on the message.

Another issue is that some messages I click on won't mark as read automatically, unless I click on another email, then back onto the one I want to respond to a second time, at which point it will finally mark itself as read (and occasionally go unread several seconds later).

A third issue is that when I switch from one email account to another, rather than keeping all unread emails open showing, it will switch to show all emails and it will automatically open a random unread email, which I'll then have to manually set back to unread before responding to the email I want to respond to. It also means I have to change the emails shown to all unread again, as well as having to change the date (I like to have newest emails at the top - Thunderbird insists on having them at the bottom). I already have the pin selected, so in theory it should keep settings from one account to the next, but it doesn't.

A fourth issue is that I'm using Conversations so show my replies in the thread in the inbox a la Gmail. Half of the time my replies show and half of the time they don't, so I have to manually check in the sent folder to see if they've actually been replied to.

Pleeeeease help anyone thank you!!!

I woke up yesterday and found Windows telling me I needed to restart my PC to install two new monthly updates: KB5013942 (Windows 10) and KB5013624 (.NET) and the related servicing stack.

[https://support.microsoft.com/en-us/t.../may-10-2022-kb5013942-os-builds-19042-1706-19043-1706-and-19044-1706-60b51119-85be-4a34-9e21-8954f6749504]

But after I did, I suddenly found that Thunderbird no longer had the ability to send e-mails -- only receive. The paper airplane icon was greyed out.

After checking some other things, I ran the usual uninstall and the ability to send e-mails was back . . . but it's gone again this morning, and the updates seem to be back. And of course Microsoft doesn't have this as a reported issue yet, either. I hope the problem can be fixed soon -- before my update pause ends.

UPDATE: To clarify the paragraph immediately above . . . this morning, the two Windows updates I'd uninstalled were back -- so, after inputting this question, I re-uninstalled them and re-booted the PC . . . but this time it didn't help. I'm STILL not able to send anything from Thunderbird. For everyone else's sake, I hope I'm the only one who has this problem. But for purposes of getting attention to the issue and getting it FIXED, I hope it's appearing on more and more screens. . . .

Struggling with TB constantly "downloading" x 10s of thousands of 10s of thousands of emails (all of which are downloaded), and the programme grinding to a halt. Have set the inboxes to a retention policy of 2500 total. So shouldn't even be trying to DL more than that. Seems to mainly manifest when I compose an email (exactly the time that the sluggishness is a problem). Have done the usual compacting/deleting * files.

This is getting to be a real issue now. I wonder if there's any paid support channels that can deal with this?

Whenever I create or "write" am email there is a grey box that shows up at the top. When I troubleshoot it is not there. I have disabled all extensions and addons and it goes not show. I tried it not using Troubleshoot and it is still there.

I have version 91.9.0

Any help is greatly appreciated.

Hi,

I have been using Thunderbird forever and had multiple email accounts in it, 1000's of emails and attachments, addresses etc and I just opened Thunderbird and EVERYTHING has disappeared!?

I desperately need to recover everything. Please help, my business is screwed at the moment and I'm in full panic mode. I am using a Mac.

Is it at all possible for someone to please give me a call?

I am not really a tech savvy person.

Thank you in advance.

Gentle Thunderbird Support or anyone that could help with the problem,

It has been at this point 3 weeks I'm trying to return Thunderbird to download my Gmail (2-step auth) emails via POP3 previously perfectly working from many years

TB stopped downloading my email with one recent version, almost probably the 91.X series, all started asking me to reauthenticate to Gmail asking for email and password in an external window (as the on the attached image)

I have read a lot of forums and contacted Gmail chat support (service for users that are paying google One services) but every time I end up blocked to the point you can see in the attached image, after clicking to Consent to the authorization request the window freeze

Here is a list of the things I have tried to solve the problem without success:

-deleting the Gmail account from TB and trying to start from almost zero -restarting TB in Trubbleshotting mode (with addons disabled) -deactivating any antivirus (useless but just to try all the possibilities) -deactivating Google 2step authentication and turning on less safe apps in Google security setting

After Google One support have tried suggesting some of the aforementioned solutions without success they suggested me to ask Thunderbird support as this could really be a bug inside the recent TB releases

Thank You Best Gaetano

I am experiencing a problem with the SMTP server rejecting sessions from Thunderbird v91.7.0 running on Fedora 36. Specifically, if I try to forward 2 e-mail messages only 1 message will make it to the SMTP server and actually get forwarded. The error message I receive is

Sending of the message failed. An error occurred while sending mail: Outgoing server (SMTP) error. The server responded: p-impout008.msg.pkvw.co.charter.net cmsmtp too many sessions from 104.33.187.187 AUP#Out-1360.

I researched the problem a bit and there seems to be a Thunderbird solution for IMAP users. However, I am using POP and I haven't found a way to configure a limit on simultaneous SMTP sessions.

This problem occurs because I am using Message Filters to automatically forward messages to another user. I think what happens is that Thunderbird is able to filter multiple messages for forwarding and tries to create multiple simultaneous SMTP sessions.

I am trying to setup support for Thunderbird Autoconfiguration, to make it easier for people to configure the software.

I have read the documentation that I can find, Thunderbird makes a ton of requests to different URLs. I've tried to make it happy buy having as many of the different URL's it is contacting return the info.

https://autoconfig.example.com/mail/config-v1.1.xml?emailaddress=user%40example.com

I can see both from the website & the developer tools, it is getting the config file back. No error in the client, other than to say 'Thunderbird failed to find the settings for your email account'.

My question is, how can I debug the issue? It is clearly getting the config file back, but there must be an issue with the config file that is preventing it from using the data in the file.

I have Thunderbird set up with several different email accounts. In December 2021, one of the email accounts suddenly stopped working. It won't receive or send emails. I didn't change anything.

I'm not knowledgeable about figuring this stuff out, so I'd be very grateful for some help. The email that's not working is a gmail account. At first I was getting an error message about the password not working. I'm positive I'm using the correct password, because I tried it on https://mail.google.com/ and it worked fine.

I have Windows 10. I updated Thunderbird to 91.8.0 (32-bit) and it didn't make any difference -- I still can't receive or send email from the problem account. I didn't change any server settings (they are the same as my other gmail accounts, except for the specific account names).

When I try to get messages, it says says Connected to pop.gmail.com...

then

connection to pop.gmail.com server timed out

I have no idea what this means or what to do. If you need more information about my settings, just let me know what you need and I'll get it.

Thanks for any help you can offer. At this point I'm desperate.

I 've used Thunderbird for several years without any issues - thank you for that - but suddenly, over the last two or three weeks when sending a message, I have been getting an authentication error message from my ISP and the e-mail is rejected. This occurs every time I try to send an e-mail after rebooting my PC.

A password change made no difference.

Incoming messages are not affected.

Clearly my ISP is blocking the messages because it is not receiving the correct password or account name - but why?

The workaround I have discovered is to enter troubleshoot mode, then send the e-mail (successfully). Then I can exit troubleshoot mode and any later e-mails are also sent successfully - until I reboot the PC and then I have to repeat the procedure again.

I am using v91.7.0 (32 bit) on a 64 bit PC and running two e-mail addresses, both of which exhibit the same behaviour.

I do not have any add-ons and I use default preferences.

Any help would be appreciated.

I can not send emails using thunderbird . I have tried to reply to emails, as well as different emails to a variety of recipients I get the following message. Go to https AUP#IPBL1000. I have not gone there, Is this a scam? How do I get back on track?

Hi,

I have several email accounts in Thunderbird (91.8.1 (64-bit), but for some reason there are always issues with my mail.com [not gmail] account. Emails have been ending up in people's Spam folders, and often when I try to send an email I get the following error message in Thunderbird: ______________________________________________

Sending of the message failed. An error occurred while sending mail. The mail server responded: Requested action not taken: mailbox unavailable Failure sending mail. Try again later. Please check the message recipient "[email@address.example]" and try again ______________________________________________

This happens at random, with different recipients - when I send the same email from my account via the mail.com website, this does not happen, so it must be a Thunderbird issue? Please help!

I've been using Thunderbird for many years and have continued using it successfully since my office changed its e-mail service from serverdata.net to Office 365 several months ago. (Server outlook.office365.com, connection security SSL/TTS, authentication method Normal password.) All was working well as of late on Sat Apr 23. When I next called up T-bird (on my Win 10 laptop) late on Sun Apr 24, I could no longer login to my account. Verified correct e-mail address and password, but multiple attempts to login were all rejected. I could still get in to my account via Outlook at portal.office.com as well as Outlook on my Android, but I can't get in via T-bird....but I hate Outlook and really would prefer to get T-bird working again. On returning to the office the morning of Mon Apr 25, I tried as well with the T-bird installation on my Win 10 desktop (which, again, had long been working fine) and immediately encountered the same problem. So it seems that either there was a silent update to T-bird on Sun Apr 24 which broke T-bird's ability to connect to IMAP on office365.com, or Microsoft did something to the IMAP service on office365.com on Sun Apr 24 which broke T-bird's ability to connect to that service. Yes, I know I could get the Exquilla extension for T-bird and try connecting via the Exchange protocols, but before I do that, it sure would be nice to know whether it's T-bird or office365.com that broke. Anybody else having the same experience? Any solutions figured out yet (other than Exquilla)? Thanks for any insights!
