Thunderbird Community Forum

I use TBird/GMail on two Windows 11 machines - a desktop and a laptop. In my All Mail folder there many emails promoting misc items, in fact over 1000 that I do not want. I have set server settings to delete immediately but no matter how I try the deleted emails reappear. They are not in the Bin or Trash. I get the same results using either the laptop or the desktop. Any ideas?

In the past week or so, I've been having multiple issues with Thunderbird. First, Thunderbird [v140] suddenly started crashing a few minutes after opening.

I checked the help community and KB to try to find a solution and none of the following helped:

Opened Safe Mode, the application continued to crash. Created a New Profile, the application continued to crash. Close Thunderbird, then deleted the Parent Lock File, the application continued to crash. Upgraded to v144.0.1, the application continued to crash.

Uninstall Thunderbird, then reinstalled, the application stopped crashing.

Upon restoring my profile from backup, I discovered several folders were missing. When I checked the Mail folder, I found many of the .msf files were missing but the folder file names were there. So, deleted my profile, created another, and restored from backup again only have the same results. This time I copied the missing .msf files from my backed up profile Mail folder, with the same results. I checked the help community and KB again and found a suggestion to copy the folder files and missing .msf files to the Local Folders folder. After copying the folder files and missing .msf files to the Local Folders folder, the missing folders appeared, including subfolders, but under Local Folders, not in my main account folder. I checked further and saw that all my emails were in fact in those folders, including in the subfolders. So I then closed and reopened the application and clicked to 'get messages' and discovered the message filters weren't working for the previously missing folders that were copied to the Local Folders. I thought OK, I'll just redo those filters.

Later on, I opened Thunderbird to get messages and discovered none of filters for the previously missing folders that were copied to the Local Folders were working. I checked further and found that the folders were there, including the subfolders and emails except... the subfolders under the newest, most recent folder I created before the crashes started.

Here's the kicker... after copying the subfolders' file under the newest, most recent folder and the .msf files back to the Local Folders folder and reopening the application, everything's there again. But after closing and reopening they're, gone again.

After all these years of deleting and creating profiles and restoring from backups with very little or no problems, I've never encountered anything like this.

I need a little help. Thanks.

Help me retrieve my inbox and its subfolders. I have used Thunderbird for 9 or 10 years or more. I know how to find Users and the thunderbird profiles but I cannot figure out what to do next. This is a disaster for me because earthlink doesn't save my old messages.

My computer (Surfacepro 6) crashed shortly before this happened. Thunderbird seems to have updated itself at some point while this was happening and suddenly it was asking me to log in. I didn't know whether to imap or pop. I should have stopped there and gotten help, but i was so bewildered that moments before I was writing emails and several minutes later - poof.

I have turned off every junk filtering option in Thunderbird, globally and for each account, yet the application started and continues to mark nearly every incoming email I receive as possible junk -- even emails from MOZILLA... It is not my ISP, nor my email provider, as they are not filtering junk, either. The banner on the preview window says "Thunderbird thinks this message is Junk mail", so that tells me it is THUNDERBIRD that is doing this. How can I get the app to stop??? There are no helpful conversations in the forum, since I've tried all of the solutions that were presented. I'm about to just delete the app and use something else which is a shame since I've been using Thunderbird for probably 20 years, but I cannot continue if this problem does not stop.

Hello, For the past few days, I've been receiving three messages. My email provider (free.fr) tells me the problem isn't on their end and suggests I contact Thunderbird. Can you help me resolve this?

Thank you

I use Thunderbird to access my Hotmail account. I normally work on my Desktop Windows 11 system but have a laptop Windows 11 which I seldom access email with. When I just tried to update the laptop Thunderbird mail I eventually get the Thunderbird message "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". There is enough free space on my drive and it succeeded writing 10522 messages before it came to a halt. I notice that the desktop is at 140.4.0 and the laptop is at 144.0.1 and help says they are both up to date.

Since the Desktop mail is up to date it would seem the quick solution is to replace the mail folder on the laptop with a copy of the mail folder from the desktop. Will this be a problem since they seem to be at different versions. Version 140.4.0 on the Desktop and 144.0.1 on the laptop.

Hello,

same issue as described here: https://support.mozilla.org/mk/questions/1487230 I use: 144.0.1 (aarch64) on macOS 26.0.1 (25A362) (MB Pro M1 Pro).

When I attempt to search for emails with a date (such as after Sept 30, 2025) in the INBOX plus subfolders (checked off), it only returns those in the INBOX. There are emails in subfolders dated after Sept 30, 2025.

If I search for a word without any date, it lists all emails. If I add a 2nd condition with a date as noted above, only the INBOX is displayed. Is this a bug?

I have a new Raspberry Pi 4; OS is version Trixie (released in Oct 2025) and I installed Thunderbird apparently successfully a couple of days ago. I had asked our admin for a new email address (just for this Raspberry Pi device) and I added it to Thunderbird apparently successfully. It successfully receives all emails.

However, sending fails with the message "login to server smtp.office365.com with username ################ failed" (the message had the correct user name)

I have retyped the password many times. No success. I have edited the SMTP server settings selecting all the Authentication Methods in turn ( no authentication; normal password; Encrypted password, Kerberos / GSSAPI, NTLM and OAuth2 which was the one Thunderbird had placed there and which google told me was the right one.)

I even tried to use smtp-mail.outlook.com as my SMTP server (Microsoft suggested this), but all to no avail. Don't think I am an expert just because I tried various things. I was getting desperate. I was supposed to deliver the device yesterday. Please help. Thanks in advance.

Hello,

I use Thunderbird for my emails and have both a customer email account and an order email account. After a recent update on my computer, the order email account disappeared, and I haven’t been able to add it back into Thunderbird.

Could you please help me restore or reconnect this email account?

Thank you in advance for your assistance.

After the most recent Thunderbird update, the connection with my Gmail account has become inconsistent, sometimes taking more than a day for Gmail messages to appear in my Thunderbird Inbox. What has changed, and how do I fix the problem?

I am trying to transition from Windows 10 to 11 but cannot log in to my AOL email account on the Windows 11 device. A message comes back "Edge: Too many requests". Presumably this refers to Windows Edge? although I have set Firefox as the default browser. I have set up my Gmail account without problem and the AOL configuration is correct. I can log in OK if I visit the AOL webpage and also still log in from the Windows 10 device. Any help would be gratefully received.

hi all

have somehow got an imap and a pop3 [version of the same acct] acct on my main pc , but they are are the same TB acct if that makes sense. suddenly ive lost all msg's in inbox.

have opened Tb in troublshoot mode but no help. i also did an "impoort" which was no help

i have 2 inboxs with associated folders [which i don't want]. i was tackleling a problem with this acct in another thread and appreciate peoples
input there, but it was not completely resolved

i suspect i need to change both accts to either pop2 or imap , preferably the one where data is kept on a server so acct is syced with my laptop pc

any help much appreciated. thanx

update: just now i did a second "Import", this was successful and recoverd my inbox msg's, but id still like some help getting back to normal, thanks

Since the error appeared that disabled the xPunge plugin (around TB 140), I have been compacting the folders in my 4 Thunderbird mail accounts manually. I wish there was a better way, but unfortunately not at this time. When I select to Empty Trash, I get messages showing quite an extensive dialog. It logs in, syncs, and even checks the folder capability of the server. When I select to Compact Files, I first get a simple message in the lower left corner "Compacting Files." Then I get messages showing each folder being compacted, and how much space was saved. It even shows reloading the last message at the end, even though the message is already there.

Since I now see this detailed dialog, I have noticed that, from time to time, the compacting fails. I get the first message, "Compacting Folders." But then nothing else. I also don't see the email message list go blank for a second when it is compacting the folder I am viewing. If I repeat the compacting folder command, it does the same thing. It appears that TB thinks the folders are already compacted, and takes no action. The only way I have found to get the compacting to work is to wait for more messages to come, delete the ones I don't want, and it will probably work on the next try. It seems to fail perhaps every 10th time or so.

Perhaps this is the same TB base code issue that is affecting xPunge? I do not get any errors, at least that I can recognize. I looked at the console, but I could not discern anything there that might be applicable - but that could be because I don't understand most of the messages there. Is there anything I can do to get around this issue? Thanks.

Hello, Here is what I consider a new bug in TB. It goes this way: While I am reading a message in the message pane of the standard window (not in its own window), if messages arrive (with a small ding for me), the message pane I am reading goes BLANK and the message I was reading is deselected. I have to reselect the message I am reading and scroll down to where I was. This behavior is very annoying and did not exists in previous versions.

I hope this helps. Thank you , Alain Damlamian

merci de votre aide

Yesterday I changed my AOL password online. Now Thunderbird email no longer works. I get a popup labelled "enter credentials for user on pop.aol.com". Within the popup window it says "Edge: Too Many Requests"

Settings have not changed and worked prior to password change. I believe if the popup window was working correctly I could enter my new password and all would be fine.

pop.aol.com 995 SSL/TLS OAuth2

smtp.aol.com 465 SSL/TLS OAuth2

Thanks,

Ed

Hi Thunderbird,

Windows would not let me keep any apps when I upgraded to Windows 11 so I am having to set up Thunderbird again. But I also had to sign into my Yahoo account again - and had to change the password. Now Thunderbird can find my address (vervelu@yahoo.com) but it cannot verify the password.

I had an email I had to send today so had to download Outlook - against all my principles! Please, please, find a way I can get back to Thunderbird and expunge Outlook! I donate every month and have done for years. . .

Best wishes, Kitty
