Thunderbird Support Forum

Dear Support,

suddenly my INBOX file has a size of 480GB - the mails in all my IMAP folders online is less than 4GB.

How can that happen?

Is there a fix or should I just re-create the account?

Best wishes, Johannes

I see that others have had the same problem as me. My trash folder has many thousands of duplicate emails. If I block delete them it will take days to complete. So 3 questions 1. How do I stop duplicate emails in my trash. After deleting many reappear with the date 01/01/1970 2. Is there a faster way of deleting. I use select email>shift key>find last email>delete 3. Is there a limit to how many emails I can put into the block mentioned in #2

I want to move a lot of gmails to the Bin but keep them in local folders. An answer to someone else's problem said to be sure the local folder contains a true copy and not just a link, by checking that I could read it, but how do I do that for several thousand emails? Maybe they are all true copies in at least in one local folder? I need to remove a large chunk of 25000 gmails in All Mail to free up space on my hard disk. I was having problems with Global Search and followed instructions to re-index everything. Apart from taking several hours to index All Mail, I subsequently found that I could no longer get 2GB free space by using Disk Cleanup, the best I could get was about 300MB, which is apparently too small for Thunderbird to compact All Mail, or for Dropbox to sync with my mobile phone camera photos. The All Mail file in C:\Users\Michael\AppData\Roaming\Thunderbird\Profiles\hgwapwu4.default\ImapMail\imap.gmail.com\[Gmail].sbd is 4.5GB, and Important is 1GB

Here is a very strange problem: 1. all my notifications about interac are attributed to only one person: INTERAC e-Transfer: A money transfer from X has been automatically deposited. Under correspondents I have Y, no matter what X is. 2. When I do a global search for INTERAC, all notifications show up, but attributed to Z, different from X and Y. Further, Z only sent me an interac transfer once, maybe 10 years ago. Indeed, if I global search for Z, none of the interac notifications show up. 3. this is ONLY on Thunderbird, not at the server.

Any ideas?

I opened Thunderbird this morning and there were no issues. Closed it and just now reopened and I'm getting this message: Thunderbird detected a potential security threat and did not continue to live.thunderbird.net. If you visit this site, attackers could try to steal information like your passwords, emails, or credit card details.

It downloaded 28 emails but will not let me see/access them.

Can anyone help? Thanks, Linda

I've read a few historic suggestions about how to resolve this, but I haven't been comfortable with what solutions were suggested as they didn't seem to comprehensively answer the questions, I'm afraid.

Until this morning's attempts to resolve the "running out of disk space" warnings, I had two mail accounts on Thunderbird - my old Hotmail account and my new personal domain based account. Both accounts had old emails (3/4 years' worth) filed locally on my PC pending my satisfaction that the new mail account was working satisfactorily. To try and resolve the storage issue, I deleted all the locally stored emails from my Hotmail account from within Thunderbird, then deleted the Hotmail account, and restarted both my PC and Thunderbird.

The expected reduction on space occupied by the .thunderbird folder didn't materialise - at all.

How can I get back the space so I can continue working, please?

I had 115.2.2 installed and all was good. I upgraded last night to 115.7 and things seemed ok but I am now on the road at Atlanta airport and I can neither send nor receive email. In the lower left corner of the display it alternately is stuck on compuserve: connected to imap.AOL.com or my other server eberger35:connected to imap.comcast.net

If I try to send a message from either my compserve/AOL, or comcast, or gmail accounts I get this error message:

The message could not be sent because the connection to outgoing server (SMTP) smtp.comcast.net timed out. Try again.

If I try to send from the compuserve or gmail accounts the message will reflect that server SMTP has failed instead.

I think everything was working at home before I left, but I'm not sure if I checked mail after I upgraded. Perhaps the problem is the Atlanta airport Wifi, but I won't be at my destination till much later today and thought I would post this now in case someone has an answer. I will be able to get the reply on my iPhone. Thank you.

Good morning. I need help with sending emails in Thunderbird. The problem has existed for a couple of days now and is confusing as some emails are sent and others fail. I am receiving mail OK. Details of my setup are :- I am using a HP All-in-one desktop running Windows 11 with Norton 360. My Thunderbird account settings: Server type: IMAP mail server User name: ****@gmail.com Server name: imap.gmail.com Port: 993 Connection Security: SSL/TLS Authentication: OAuth2 Outgoing Server (SMTP): Google Mail – smtp.gmail.com (Default) User name: ****@gmail.com Port: 465 Connection Security: SSL/TLS Authentication: OAuth2

The problem: I only recently set up Thunderbird and at first it seemed to working OK. However, now when I try to send a message, after some time, I the following error message :-

"Send Error Message Sending of the message failed. The message could not be sent because the connection to Outgoing server (SMTP) smtp.gmail.com timed out. Try again."

What is particularly confusing is that some messages are being sent. I have tried several fixes that I found from the Mozilla, Google and Norton web sites but none of the fixes resolved the issue. Any assistance would be very much appreciated.

Regards Mike

PS: I have 2 email accounts set up in Thunderbird. I just tried sending a test message from the Gmail account to the Bigpond account. From the Gmail account it appears to have been sent but in the Bigpond account an error message appeared as follows :-

"Could not connect to the mail server smtp.telstra.com; the connection was refused."

I don't know if this is a related issue or I have another one to resolve.

My phone has been deleting emails from my mozilla account and removing them from my laptop. Although I can still delete from my phone they don't delete from my laptop. This system has been working for years and I've only just noticed the problem. I normally use my phone for this so I have about 3 months worth of emails still on the laptop.

I installed Thunderbird and eventually got it working. I download with IMAP and upload with SMTP. TB did a great job downloading gobs of email from Gmail and converting the labels into folders. In a couple cases, it created folders, but none of the emails with that label were downloaded into the folder. FOr example, there is a folder 'PE' and a subfolder " CD Ads'. Emails are present in both. However, in TB, 'PE' is lighter grey and italicized and empty.

The folder structure is not an exact match to the label structure. For example, in the labels, I have an 'Employment' label with 5 employers underneath it. None of the employers made it into TB.

I have a few other oddities too, but lets start with these. I did end up using a normal password to access the account, as 0Auth2 would not cooperate.

Thanks for you insites!

Hello, I recently installed Ubuntu 24.04 with the version of Thunderbird (115.10.1) supplied with the distribution. I can no longer display mail saved as .eml in a remote folder (sftp). Thunderbird opens, but the mail window is empty. If I ask for the source code, this message appears:

Unable to read file at address view-source:file:///run/user/1000/kio-fuse-ouSeRu/sftp/myuser@myserver/mymessage.eml?type=application/x-message-display.

If I open from CLI I get this message :

JavaScript error: chrome://messenger/content/aboutMessage.js, line 218: NS_ERROR_FILE_ACCESS_DENIED: Component returned failure code: 0x80520015 (NS_ERROR_FILE_ACCESS_DENIED) [nsIMsgDBHdr.mime2DecodedSubject]

If I open the save file with a file editor I'm able to see the source code.

Could you please help me? Thanks

I had an email account from my university that used gmail in the past but just recently disabled the email and migrated away from it.

However, when I removed that email account from thunderbird and restart the app, the oauth dialogue to authenticate the disabled account each time. It would also keep opening that dialogue every 30 minutes. Any help is appreciated.

I am using a Mac with Big Sur (macOS Monterey, Version 12.7.5), and my email is POP, using Thunderbird Version 115.11.0.The message count of my inbox is wrong. It is two (2) more than it actually is. Right now there are ten (10) messages in my inbox BUT the message count of my inbox says twelve (12). Please correct.

TB won't set up on Yahoo mail. Spent about 3 hours on the phone with one and sometimes two Yahoo techs and giving them total access to my computer so they could set up TB but could not get it working. It was eventually suggested I contact you folks, so here I am. When sending an email, it just keeps running like it's sending but doesn't stop. Eventually displays the following:

Sending of the message failed. Unable to authenticate to Outgoing server (SMTP) smtp.mail.yahoo.com. Please check the password and verify the 'Authentication method' in 'Account Settings | Outgoing server (SMTP)'.

The techs and I went around an endless loop of re-entering PW and checking authentication settings. Any suggestions?

I was using thunderbird. I accidentally hit the sort by star right above the email list. The application crashed closed. When I reopen it, it immediately crash closes. I can't even get an pointer arrow for long enough to exit myself.

On window 10. Thunderbird was up to date.

Tried - restarting computer. Signing out of TB in the crash report box. Can't get into safe mode.

I accidently powered off system (PC with Windows 10) without closing programs, including Thunderbird. After restarting the system and opening Thunderbird, TB crashed. I have tried numerous fixes:

• Installed the latest version of TB (from 78.11.0 to 102.8.0)
• Opening TB in Safe Mode (disabling all add-ons, reset toolbars & controls)
• Uninstall & reinstall TB

All result in the Crash Reporter dialog, with Report Contents. I can supply the report contents. (It wasn't obvious how to attach to this forum post.)

One KB item (https://support.mozilla.org/en-US/questions/1337785) suggested that the issue may have to do with session.json file. Based on the file timestamp, that seems likely. But I don't know how to edit this file to fix the problem.

I also created a new TB profile, with does not crash on startup, but I cannot get email properly configured.

I have hundreds (maybe 1000s) of email stored in TB that I cannot access.

I would greatly appreciate any help!

Hi,

I have a user who sends me an email to one of my email addresses and it always ends up in the Junk folder. I've repeatedly marked his emails as not junk but that doesn't seem to change anything.

Is there anything I can look at that will help me figure out why it happens, and hopefully find a way to fix it.

I'm on Betterbird in case that matters. I looked thru the release notes and there seems to be nothing tagged with the junk filter.

I noticed this in the X-Proofpoint-Spam-Details email headers: mlxlogscore=764 clxscore=1015

This person seems to be the only person that has this information in their headers. Is it added by the junk filter? Or is it something on the sender's side (he uses an icloud.com and a me.com address)?

Thanks,

L

Has anyone seen a message similar to this when trying to attach a document, usually a pdf to an email?

O:\XXXXXXXXXX.pdf could not be opened, because the associated helper application does not exist. Change the association in your preferences.

Also, when someone send me an image file, I can't open it directly from the email. I have to download it and then open it. This isn't as big of an issue as the above, but I thought I'd ask it too.

Thank you

Windows 10 Thunderbird 115.10.0

Since yesterday, Thunderbird will not connect to my TalkTalk IMAP mail server unless I switch on a VPN. This is inconvenient. I have no problems accessing my emails through TalkTalk's online mail service, which doesn't happen when the server is down.

115.05 when I started.

I typically open Thunderbird about once a month, download my emails from a hosted website, do some clean up, write some emails, close Thunderbird, and do the same about a month later.

Today I opened Thunderbird, saw that it was downloading around 400 emails in the lower left corner, and waited patiently, as per usual. When "done", however, none of them showed up in the main window. The latest email did not change, was still from around a month ago. When I ask Thunderbird to Get Messages it says there are no new emails to download.

I restarted Thunderbird several times, no change.

I then upgraded to 115.10, hoping this might fix the issue, but it has not.

Since restarting Thunderbird, 2 new emails have come in and are showing correctly, but none of the initial 400 emails "downloaded" today are showing anywhere.

I repaired the Inbox folder (right click > Properties > Repair Folder), no help. I renamed the "Inbox.msf" file and had Thunderbird rebuild it, no help. I renamed the "global-messages-db.sqlite" file and had Thunderbird rebuild it, no help. View Ignored Threads does not help. View > Threads > All is selected. Emails are not in the Trash folder, or any other folder.

All of the initial batch of 400 emails - and the emails I had previously opened - just disappeared.

Opening up the Inbox MBOX file directly, I can see that these 400 emails were never actually downloaded into this file. Not sure what happened.

Opening up my remote email host, I can see that those 400 emails are still there, to the exact point when I last closed Thunderbird.

Asking Thunderbird to download new messages does not download these remote emails.

How do I reset Thunderbird to start the process over and re-download these emails again? Part of TB seems to think it's already downloaded these emails, while another part of TB never actually did.

Does anyone have any idea what to do here?
