With version 128, now when I open Thunderbird, I get a notification alert and sound for every new email. If I have 20 new emails, I get 20 notification alerts and sounds. Very annoying. The previous version would have one notification saying I have 20 unread emails. Much better.

Outlook is used on one PC with POP3 data retrieval. Messages are only deleted by the email service provider if they are deleted in Outlook.

Thunderbird is also used to access the same accounts with IMAP access to the online accounts. All of the messages online have been downloaded by Thunderbird.

I am comparing the .pst Outlook files, and the various Thunderbird data files stored by the PC.

The Thunderbird data files are much larger than the Outlook files. For example, the largest Outlook .pst file is 2G. But there is a Thunderbird data file that is 8G.

Any reason or problem or cleanup suggestion regarding 20G of Outlook .pst data that appears as 30G of Thunderbird locally stored downloaded IMAP data?

Hi. I am using Thunderbird 128.2.1esr(64-bit), most recent update. Recently (about 1-2 months ago approx) some of my emails have started having an attachment that does not belong with it. For example, I just received an email that I know for a fact was not sent with an attachment, however in my inbox it shows that the email has an attachment. It is always the same attachment and is always the same file name, and is a file I received about two years ago. (The fie that gets attached is a legitimate one from a trusted source. It is a pdf file, and is always the same one when it gets attached to incoming emails). I can open the attachment everytime when it shows up, so it is acting like it belongs with the specific email, even though I know it is not supposed to be there. I also noticed that when this happens there is no text in the email message, just the attachment. This happens at random times and does not seem to have any specific pattern. I use a gmail account & am connected by imap. If I go directly to my google inbox the specific email shows as normal, meaning the attachment is not with it, and the text of the email shows up. How can I fix this? I have tried compacting my folders however that has not helped. I have scanned for any malware and the scans show no issues. I do not know what else to do. Any help would be appreciated. Thank you. Rich

For the past week or two, TB only downloads 3 or 4 (never more than 4) messages at a time from my Gmail. Now, instead of just starting TB and it downloading all new messages, I have to click Get Messages multiple times to retrieve everything. I have seen similar questions here and the answers have all been variations of blaming the user. So: a) I have not changed any settings. b) It used to download all available messages, whether when TB started up or when I clicked Get Messages. c) Just now on starting TB, it took 6 clicks to retrieve 20 message. They are all text, no attachments, so the total size would be in KB, not MB. d) Using Speedtest, my connection speed is over 300 MB/second so it isn't a connection speed limit on my side. And I doubt it is a speed limitation on Gmail's side.

With all of that in mind, I would appreciate any suggestions of what could be causing the problem and what the fix might be.

After a power outage I now get this message on all three of my computers but only on some accounts:

"An error occurred while sending mail, The mail server responded: <1234@roadrunner.com> sender rejected. The email address you are sending as must match the email address you used to auth. Please check your SMTP settings, AUP#Out-1500. Please verify that your email address is correct in your account settings and try again."

I know what that means but I'm very confused because I use and have always used ONE <default> smpte for all my accounts and never had a problem until now. Thunderbird even gives the user a choice of whether to use one default account or separate smpte password statements for each account. I still can't send when I try to enter separate urls and/or passwords for each account. Anyone know what's going on? Thanks, Joe

Email was fine until around 1. Now all of a sudden it won't send outgoing email. It just sits there and spins. This happened last week for few hours, but that was just before the latest thunderbird update. It's annoying.

Hallo Team, bisher hatte ich mit Thunderbird keine Probleme, aber kommt wie aus den nichts immer die Meldung. Anmeldung auf den Server imap.arcor.de mit dem Benutzernamen "f.heben" fehlgeschlagen. Nochmals versuchen. Obwohl ich die Meldung anklicke, erfolgt keine Anmeldung,, sondern der oben genannte Hinweis kommt wieder. Warum? Muss ich etwas reparieren? Mit freundlichen Grüßen Franz Hebenstreit

I am new to Thunderbird having just installed version 128.2.1esr. I am trying to build distribution lists, what you refer to as mailing lists. Your support document says to open the Address Book then Select File>New>Mailing List. When I try to do this after selecting File>New Mailing List does not come up as an option. Is there another way to build my lists? Thanks

when I select multiple msgs using the shift-arrow keys and hit delete an error pops up that says "msgs could not be moved or copied to the trash folder because writing to the folder failed. To gain disk spaces, from the file menu, choose empty trash, and then compact folders, and try again"

I've done this and it still does not work. I can delete msgs 1 at a time but when I get so many a day that takes a while.

I've tried reinstalling thunderbird to no avail.

Thanks!

I need to talk or chat with someone who can walk me thru a solution. Your online helps are beyond my comprehension. When I try to send, or reply to, a message, I get a screen saying "Password required for outgoing (SMTP) server.twc.com." HELP!

Dobrý den, na starém PC jsem měla v nastavení serveru typ POP. Aniž bych cokoliv měnila, při instalaci Thunderbird do nového PC mám najednou typ IMAP. Jak se typ serveru dá změnit? Jde mi o možnost zaškrtnutí volby Ponechat zprávy na serveru. děkuji Iva Gurecká

While transferring Mozilla Thunderbird from my old MAC computer (OS 10.11, TB 78.14) to my new MAC computer (OS 12.7.6, TB 128.1.1) everything went well except that the “inbox” for 2 of my main accounts were not placed at the top of the left hand column with my other account inboxes. I found them in the account “envelopes” at the bottom of that left hand column. 1. How can I move them back to the top of the left column under the “main general inbox”? 2. How can I reorder these inboxes so that my main inboxes are at the top? Any help would be greatly appreciated. Thanks.

Can no longer send/receive email. Error message about "certificates", ports?, IMAP? settings......... Have tried various combinations and receive a variety of error massages.

Hello, I recently bought a MacBook Air 2024 with G3 chip (Sonoma 14.6.1) and used Time Machine to transfer all the data from my previous Apple MacBook Air from 2015 (Mojave 10.14.6) to the new computer. This also transferred my Thunderbird profile folder. It has the extension .default and an 8-digit combination of letters and numbers in front of it. Since the old version of Thunderbird no longer ran on Sonoma, I installed Thunderbird 115.15.0 and then opened Thunderbird on the new MacBook Air. Since then, Thunderbird has been taking an extremely long time to open (much longer than on the old MacBook Air with Mojave. Yesterday I updated to 128.2.0esr, which didn't help either. I deleted a deactivated extension in the add-ons, so that there are now no extensions, only a few dictionaries that I deleted as a test, which also did not bring any improvement. Switching off the hardware acceleration, clearing the cache and changing the themes did not improve the situation either. With the themes, I can only switch between dark, light and system theme - automatically. I checked and made sure that Thunderbird actually loads the .default profile folder from my old computer as the active profile. However, Thunderbird has also automatically set up a second profile with the extension .default-release. Could this be causing the problem? My active profile folder has a size of 15.21 GB and the new .deault-release profile folder has 18.6 MB. Both profile folders are located in Library/Thunderbird/Profiles I am quite desperate and hope that someone can help me. Thank you very much!

I have been assiduously marking all the junk and non-junk items coming into my junk mailbox for over a month. The situation was better, the volume of junk mail was decreasing by half every two weeks. Now it is rising again to pre-thunderbird levels. Has something happened to the junk mail filter to stop it from working? Why does it take so long to identify junk. The same words keep appearing: debt, lawn, lawyer, cancer, zantac, loans, credit, glasses, frames, windows, insurance, fitness. If I can spot these why can't a the filter. Honestly, this spammer is driving me nuts. My account is with hotmail.com.

As the title says, when I enable the "Digitally sign" option for OpenPGP in a new mail, I get "Sending of the message failed" when trying to send, but if I disable only this option, then the message sends successfully.

That is the case whether I encrypt or not the message.

The versions of Thunderbird I tried where: 115.14.0 and 128.1.1esr.

Please, explain me (with pictures) what should I do, to be able to read my received emails in Tb

I run Thunderbird on a PC, and, to free up space on Drive C:, I have moved the contents of the folder Thunderbird in Appdata to Drive D:. I then changed my Server Settings, in Thunderbird, from C: to D:, and note that any new mail is indeed now appearing there along with those already transferred. This move could save me a valuable 6 gig of space, and more in the future, however, I am unable to remove that original Thunderbird folder entirely, notably I am unable to remove the contents of the Profiles folder, as it is still linked to the application. Notably with cookies.sqlite, cookies.sqlite-shm, store.json, mozlz4, aborted-session-ping and many others, which I note some have continued to be updated. I have been unable to find any other settings in Thunderbird referring to Drive C:, other than those in Server Settings.

I could presume that if I installed another version of Thunderbird on Drive D: and maybe moved those existing contents of the Thunderbird folder on C: onto Drive D:, and made those numerous settings changes to the App it could work. But I ask is there an easier way to complete this move? How can I complete this transition of Thunderbird from Drive C: to Drive D:?
