I can no longer send messages through the email client on one of my accounts using Thunderbird, which no longer recognizes my internet service provider's password (but it does receive messages). Everything works fine with my other accounts.

Thank you for your help.

why just today is all my incoming emails coming to trasha nd not my in box in Thunderbird worked fine in the morning but i am not getting any mail in my in box it is all going to trash

I have a new laptop and did a backup of my files on the older laptop (Windows Home) and restored them to the new laptop (Windows Pro). Then I installed Thunderbird on the new laptop and I already had e-mails on it. But there are thousands of e-mails in the wrong folders.

The Windows Home has Thunderbird 128.10.oesr (32 bit) and the Windows Pro laptop has Thunderbird 128.9.2esr (64 bit). What should I do? Should I uninstall Thunderbird on the new laptop? Then what?

I need to do something with a profile folder, right? But what?

Please help.

It's a mess right now.

Starting on 10/01/2024 Thunderbird no longer allows me to send or receive email.

When I try to read messages using Thunderbird, I get the following: Sending of password for user XX@msn.com did not succeed. Mail server outlook.office365.com responded: Logon failure: unknown user name or bad password.

When I try to send messages using Thunderbird, I get the following: Enter your password for XX on smtp.office365.com:

I have tried redoing the password and it does not help.

This is on a WIN/10 system. I updated to the latest version of Thunderbird and it did not help.

I checked out Thunderbird on my WIN/XP and get the same results as with WIN/10.

When I use Firefox and login to https://outlook.live.com/mail/0/, I can send and receive email as before. The same is also true with my Mobile Phone.

The global search in TB is completely defective. I am now running 128.2.0esr and hoped that update might fix it. It hasn't. I just wonder, are there any older or non ESR versions I can downgrade/move to, where the search is fully functional?

My thanks again to sfhowes, Rick and others for assisting me to get back my ability to once again send e-mails from Thunderbird. Now for the next step.

Just days ago, I migrated my years of Thunderbird e-mails on a POP protocol to IMAP. Before doing so and before also uninstalling my old Thunderbird because of e-mail sending problems and then reinstalling a new version, I saved a profile. Now with the most current version of Thunderbird, I lost (i)a decades worth of saved inbox e-mails (but for the last 2 years), (ii)I lost all of my sent e-mails but a few odd ones, (iii)I lost my archived e-mails in Local Folders and (iv) I lost all of my contacts and saved group e-mail address lists.

My profile is saved on an external hard drive. Obviously the new installed version of Thunderbird must have somehow found the last 2 years of my inbox e-mails but nothing beyond that as mentioned above. Can you share please a recommended procedure where I can better import what I assume I saved correct on the profile I saved twice (I saved a master folder named Profile and separately saved 4 folders - 2 folders ending in default and 2 ending in default-release. Thank you.

Is it possible to open incoming mails in the same window as the list of e-mails, just like in Google? I get distracted from seeing suddenly my e-mail in another window/tab.

Thank you!!

When I reinstalled Thunderbird, I got my account back, but the Local Folders were missing. I found where they're hiding on my computer, but I can't figure out how/where to copy and paste that folder so they show up in Thunderbird. Can someone walk me through those last steps, please?

Thanks

I exported my profile to an external drive, then reset my Windows 11 PC. The resulting file is a zip file. When I import, the import starts, then stalls and gives an error. The error log is incomprehensible to me. How can I not lose my local folders and messages? I tried unzipping and importing that folder, but another error. I need help! Ideas? Thanks.

I was forced to erase my PC because it was infected with malware. I saved my Tbird profile to my HDD before erasing. I pasted the saved profile to %Appdata% >Thunderbird, copying 1,777 items. When I brought up Tbird, I got the Account Setup window, so I don't think the profile was actually there. What did I do wrong?

Hi all,

After thoroughly searching this database, I could not locate an answer to the issue I am facing, although there seem to have been several similar cases.

My former university has recently decided to delete alumni email accounts, so I am using Thunderbird for email transferring from university to GMail (added both accounts to Thunderbird and then began copying emails and folders). Transfer is slow, depending on the server capabilities etc., but I am going folder by folder and so far it has been fine. I began the transfers a week ago.

Last night I noticed my Thunderbird inbox for my school is not showing anymore. The profile folder is only showing one file (.msf) for Inbox, instead of what should be, in my understanding, two files.

Thunderbird is still communicating well with the university email server because I made a folder rearrangement on the university webmail service (outlook.com) and it showed on Thunderbird. In addition, all my Inbox emails appear fine on the university webmail service (outlook.com).

Any ideas? This is obviously important and urgent.

Thank you in advance.

Hello All, I'm new to Thunderbird and here is something I'm wondering about: I created all my accounts and set everything to Unified ... all works fine. All 5 accounts show under "All Folders" ... if it's also checked, but I don't use it usually. In Unified view, however, UNDER the unified folders, my primary account is missing...?!? Again, I'm talking about the account list UNDER the unified folders! ... not the "All Folders" list! (if it's checked) (I usually don't have "All Folders" on)

The drop-down lists of the single unified folders, however, e.g. Inbox, Sent, etc., DO SHOW the primary account! (On a side note: under Drafts only four accounts show ...?)

So, why is the primary account missing in the list UNDER Unified folders ... (there are only four plus "Local Folders") but it is listed in the separate unified folders, if opened..? I hope explained it clear enough.

Please see attachments

BTW, at my home computer, ALL accounts are showing (in Unified view) under the unified folders. Please let me know what I did wrong or if I have to explain it better.

Thanks

Just installed TBird on new laptop, had an awful time. On the main mail page, across the top, there is a search bar (ctrl k). Should there be a 2nd one below it in the middle? Trying to configure it exactly like my older one, but can't find the right selections. Had remote help from BestBuy Geek, she only got half of it. The 2nd search bar is there, and tried to take a snap of it but can't get it. It has the threads symbol, the attached symbol, and one other on the left, and at the end of that line is the symbol to select them. She missed that completely. Can anyone tell me what that part is called, and where to make the selections from? (easier if I could show it to you, sorry) As always, Thank you! Stacy

I used to troubleshoot when Thunderbird would fail to download new messages by looking at the last successfully downloaded email. But I can't find the error log. I'm pretty sure older versions allowed you to see the error log under Tools. But it isn't there and developer section is not helpful. I have tons of message filters going into folders so it is impossible to identify the last successful email download.

How am I to fix this issue if there is no longer a way to see failed email downloads via the error log?

I wasn't happy with the UI changes burying the menus into the hamburger on the side, but figured I could live with it. Not sure the benefit, maybe it looks cleaner? But removing functionality at the same time is really NOT helpful.

Anyone have any ideas how to find the error log or find the email causing Thunderbird to stop seeing downloadable emails?

Trying to change the color of the unread background and the top header bar. Got the unread message color change to work.

But if I try to change something else, it doesnt work. I dont know how to combine these codes properly.

thunderbird 142 or latest. windows.

I inadvertently deleted a mail sub folder named Shopping Oder Confirmations I found the folder in my acronis backup and copied it to my desktop I then pasted it in to the profile window of thunderbird in hopes that when i restarted it would show up in my mail folders which it did not I can send you screen shots of the different windows where I dropped the folder Can you help please?! There is tons of information in these folders I reference often. Thank you! BTW I did just make a donation :)

I hope someone can help here. I have used Tbird and FF almost exclusively from release. Thundebird is my only email program and the whole thing is playing up badly at the moment. I can send no emails. Some emails that show in the inbox show a blank screen and can not be deleted. All messages I send come back with an end of message error and SMTP blocked (see attached). This happened a few weeks ago and my email sourse gave me some new settings using port 587 and it worked ok until a few days ago then exactly the same again. They have checked and everyting works ok for them. I then checked with BitDefender to see if they could assist and everything was as expected so I did a complete computr scan with it and it came back with 3 trojan errors all of which were in Thunderbird. So I decided to do a complete delete and reinstall. No matter what I do or what I deleteincluding shutdown after every delete, when I reinstall it comes back with the total and Faulty Thunderbird So I can't start with a clean sheet. Not that I would like to as I have hundreds of contacts an email saves going back many years. Suggestions anyone

I have seen many questions a bit like mine but they all refer to downloading emails. Mine is different: "The folder 'Trash on my@email.com' 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." It now happens on two different email addresses (one is POP one is IMAP). Trash seems otherwise to work and can be deleted. But still this alarm. MAS OS 15.1.1 (24B91) - latest Thunderbird 128.5.2esr (64-bit)
