Thunderbird Community Forum

I just installed Thunderbird, linked it to my primary email account (ok!) and then tried to import one year's worth of email messages exported from my Apple Mail client as .mbox folders with an underlying folder structure (1 per month). Thunderbird went away for about 2 hours "downloading" and importing ( ... looking good!), but at the end my "Local Folder: Apple Mail Import" still shows no messages. Where are they and how can I access them in the Thunderbolt client?

I have Version 128.5.2esr (64-bit), it says it is up to date.

So I've been noticing a couple of days now that I can no longer view messages in the message pane to the right of the screen. When I click on an email in the list on the left, the top of the pane on the right shows me the To, From, subject etc, as well as a yellow bar saying "Warning: To protect your privacy, Thunderbird has blocked remote content in this message." Then, nothing underneath this. Where it used to show the email contents. I do NOT want to have to double click every single email in my inbox to look at them in a separate tab. Most of what I get is not useful. I want to be able to click once and preview the email, then click Down to check the next one, and on and on the same as Thunderbird did it LAST WEEK.

Can someone help me get it back to working please? Thanks!

I'm running Sequoia 15.1.1 on an M1 Mac Mini. Never had problems before. TB 128.6 0 esr.

As soon as it opens it crashes.

I have a lot of unopened files in a pop mailbox, going to try and remove them.

It seems to still work on my iPhone. Any ideas?

I M get this working. I'm in a panic. Please help.

Some emails I receive, when I reply to them, don't correctly display the email (body text) correctly. It looks like Thunderbird is choosing the wrong font colour for the reply email text and I'm after any info on why this happens and how to fix it.

Attached are two screen shots. "original.jpg" shows the original email and "reply.jpg" is my reply email. It doesn't always happen and it *may* be emails sent out by Zendesk.

I'm on latest TBird 128.6.0esr but it's been happening for the last few releases.

I have been having much trouble with Thunderbird. The latest problem is with the Sent folder. When I try to Compact Folders I get the message "The folder 'Sent on Local' could not be compacted because writing to folder failed. Verify that you have enough disk space, and that you have write privileges to the file system, then try again."

I have plenty of disk space and have Full Control. I tried creating a temporary folder and moving all the Sent messages to it, so that Sent had zero messages. I still got the same message. The file listing showed Sent to have a size of 182 MB even though it didn't contain any messages. I've tried deleting sent.msf to force Thunderbird to recreate the index - didn't work. I tried using Repair Folder. That worked, but when I tried Compacting Folders again it found another folder with the same problem. I fixed that one and then it said the Sent folder was bad once again. I'm going around in circles!

I've deleted and recreated scores of .msf files for various reasons, trying to get Thunderbird to work without errors, but as soon as I get one problem fixed, another one crops up. I'd conclude that it's my computer, except that I'm not having any problems with other programs.

Any thoughts on this particular problem or Thunderbird problems in general? Thanks.

I have tried to install thunderbird on an iPad Pro to transfer email etc from MacBook Air and now neither one will retrieve new email messages. Responce is account has been blocked / blacklisted.

After I've successfully logged in, why does Thunderbird continue to indicate my login has failed and asks me to login again, repeatedly? Do you know how I can fix this?

When I opened Thunderbird to get and read my new email I received this error message after I could see that Thunderbird had found new messages.

"Unable to write the email to the mailbox. Make sure the file system allows you write privileges, and you have enough disk space to copy the mailbox."

I checked the hard drive space on all of my hard drives and I have GBytes of space and in PREFERENCES for the hard drive, WRITE is allowed. In fact all items listed in Preferences is set to allow.

I've rebooted the computer and even had Windows check my hard drive for errors and it found no problems. What do I now need to do? Thank you. Fred Berney

Somehow, I have a second copy of one of my email accounts. They are mirrored, so what happens to one, happens to the other which makes deleting one not acceptable.

Any way to get to the mirrored account?

Thanks, Sue

Hi everyone.

Since I constantly switch between multiple computers, some of them Windows, some Ubuntu, some dual boot, I have installed portable clients for both platforms onto an USB stick. These are set up to use the same profile folder. Generally, this works fine.

However, I have one issue with my POP3 accounts, which are set up to keep messages on the server for 7 days. After I have fetched a message with the Linux client, checking for messages with the Windows client will fetch the message again, resulting in duplicates.

I checked the data being written to popstate.dat and checked the knowledge base to find out the issue. I found out that the "Flag" (always "k") and "UIDL" sections are written identically by the two clients, but the "Timestamp" section is different, which causes the issue. According to the knowledge base, "The message's time stamp in the file corresponds to the date and time in the From - line at the top of the message source." Needless to say that the message sources of the duplicates are identical, so this doesn't add up.

So here are my questions: 1. Why is a timestamp written to popstate.dat in the first place? Shouldn't the UIDL be enough to uniquely identify a message? 2. Why is the timestamp calculated differently from the same source data on Linux and Windows clients?

Thanks, Ansgar

This appears EVERYWHERE: emails unreadable (blurred). BUT if I select (left-button + mouse movement), a whole section (NOT the whole message) becomes crystal-clear. I have saved many such incidents, but one is below:

This problem started after the latest Firefox update was installed. I have looked in Thunderbird Solutions but with the only one that comes close to my problem the person was able to switch to a different profile. I don't have another profile that I can do that with. In another one the problem was solved with a bug fix in a newer version. I already have the newest version. ??? Please help.

Thunderbird, quite suddenly, stopped getting my email; Both on my account and my wife's account at the same ISP. I spent more than two hours on the phone with the ISPs help line trying to resolve this issue. They also use Thunderbird at their help desk, and the agent I talked to was familiar with your program. She (the agent) was not able to replicate the issue on their system. We then tried to set up a NEW email account. I carefully entered all the info needed for a new account, following instructions from the agent, then hit the 'Test' button. I got the following message onscreen: "THUNDERBIRD FAILED TO FIND SETTINGS FOR YOUR EMAIL ACCOUNT" The answer to the original issue suddenly became very clear - Thunderbird cannot, or refuses to, connect with the email server, therefore NO EMAIL. We tried everything in her toolkit to resolve the problem to no avail. We finally tried UNINSTALLING Thunderbird (and the Maintaince program). Once Uninstalled, I used the Registry Tool on CCleaner to remove any entries in the registry referring to Thunderbird (there were several), then restarted my computer. I then downloaded and installed a totally NEW Thunderbird program. When I ran the Thunderbird again, I found all my account(s) info was still present, and Thunderbird was still unable to find the server. I'm at my wits end trying to resolve this issue, and REALLY HATE to go back to Microsoft OUTLOOK to get my email. Anybody got any ideas??? Any help would be greatly appreciated. (Signed) Proteus

recently i am having problems with sending emails from my desktop, via thunderbird. it keeps asking me to sign in with my new password. however i have not changed my password with virgin. i can send an email from my phone, so i know its not virgin. i have spent 3hours reading up and checked the server and outgoing settings, and changed switched adjusted what i could see, and set them back to the original settings, which in effect meant i have done nothing, and all of a sudden it works again. this did happen a couple of week ago, so not sure what's going on, and i really haven't got a clue what im doing, so any help or advice would be appreciated.

see attached. When I right-click on the sender's name, nothing happens . . . .

[also, when I "browsed to get the file to attach, your system ignores all .BMPs. Very frustrating. And, why not allow us to drag an image?]

This all started when I cancelled Xfinity and went to Frontier Internet. I had previously used Thunderbird for 8 years through Xfinity with no problems. I have contacted Xfinity and Frontier and both have told me it is a problem with a Thunderbird setting.

Sending of the message failed. An error occured while sending mail: Outgoing mail server (smtp) error. The server responded: resomta-c2p-555920.sys.comcast.net resonta-c2p-555920 sys.comcast.net. Excessive failed authentication. ESMTP server temporarily not available.

Je ne puis plus éliminer les messages dans la corbeille malgré avoir suivi les instructions pour le faire. Je ne sais pas non plus désinstaller Thunderbird ! Je voulais faire une réinstallation mais cela semble impossible et vraiment je ne comprends pas pourquoi  ? J'ai fait un transfert sur un autre pc en suivant les données sur ce sujet et cela fonctionne. Pourrais-je faire la même chose en sens inverse ? Merci pour votre réponse

Is it possible to change the default calendar in Thunderbird so that my google calendar is automatically used when creating a new event rather than "Home"? It would be useful when creating events not to have to remember to change the Calendar from Home to another from the drop down menu. Grateful for any help.
