I have a problems receiving and sending emails from and to externals users. However I don't have this problem with the emails receiving and sending between my coworkers (we have the same domain @spectratech.gr). We checked the SMTP settings (IMAP/POP3), SSL/TLS settings, updates and these setting seems to be ok. What could be the problem? thank you

Hi - I have a problem very similar to https://support.mozilla.org/en-US/questions/1493859?page=1 I think.

I am unlikely as technically savvy as user @iwright2 though.

I am running a MacBookPro 14.1.1, Thunderbird 129.7.1esr

Like the other user, this is no doubt due to my overstuffing of folders. I have, as a friend says, terrible computer hygiene.

I can see from the size of the empty inbox that there are many messages there. These messages all display in AllMail and outbox. These are all embarrassingly large.

I believe the problem stems from my searching on a string in one email's inbox and highlighting just these - they numbered n=60 I think, and I transferred them to an inbox on a different email account. They transferred slowly and after that, the entire first folder was empty.

This is a mac, running a lot of different gmail accounts all as IMAP.

Perhaps I need to restore some file, but I'm pretty nervous to do this. I will backup the computer first.

I'm not sure what else to tell about or investigate. Is there anyone who might be willing to help see me through trying to restore these emails to visibility. I tried someone's suggestion to change the display parameters, but that doesn't work. I must have messed things up in the transferring. I can also try repairing a disk as suggested in the other thread, though I'm not sure that's the root of the problem, I think the transfer amid way-too-big-files is.

Thanks - Huge Thanks!!! - if someone has a thought/suggestion as to where to start.

Hello, Since tuesday (2025 february 25) I can no longer send e-mails from my main account, whoever is the recipient. As soon as I clic on "Send" I get the message below: "Sending of the message failed. An error occurred while sending mail. The mail server responded: : Client host rejected: Access denied. Please check the message recipient <recipient address>". I did not change anything. I have the exact same issue on an other computer with the same Linux distribution (Xubuntu 20.04, both up to date) running the same Thunderbird version (115.18.0). What is weird is that I have no trouble to send e-mails from a secondary account, on both computers. I checked using openssl that the problem is NOT related to the smtp server. Anyone experienced the same weird issue? Thanks in advance for any help. Lucie

My Macbook Pro has been crashing - sometimes Firefox, sometimes Thunderbird -sometimes multiple times/day. I've saved many of the crash reports in case they might help someone know how to fix this. An Apple tech person diagnosed my memory was broken, so I just got a new logic board and reinstalled all my data from my Time Machine backup. Then a message popped up that Thunderbird was damaged and should be put in the trash. Around the same time i replied to an email from someone at Thunderbird donor who was responding to a question i had about a small donation i tried to make - i explained i was having trouble with Thunderbird. At that time, i could see the Thunderbird icon in my task bar. When talking with someone from Apple support this evening who was helping me answer a couple of questions, including about a new "mail" icon that showed up in my task bar, I mentioned that i'd like to learn how to back up or archive my emails in Thunderbird. That's when i saw that the Thunderbird icon - had disappeared. The Apple support person and i searched all over my computer for the Thunderbird app, but couldn't find it. I'm really nervous. I have over 300,000 emails I've been wanting to learn how to archive - or something. I don't want to delete most of them. I hope someone can help me find everything. Thank you.

I just changed the incoming and outgoing servers on Thunderbird. Both are the same server name. I can send emails but when I check email, the incoming server times out. I added the account that I check with Thunderbird to Outlook and it both receives and sends emails.

so i made my Microsoft account [email]@GMAIL.com insted of [email]@outlook.com so then how can i use my microsoft account WHEN thunderbird knows @gmail= gmail.com and knows @outlook = outlook.com PLS HELP PS: im useing family link so im useing a bypass from microsoft. ;)

personal information removed from a public forum

Trying to create a Group of ten people. Went to New Message, File, New, Connect where I filled out the Group name and emails of people in in it and then clicked add to Personal Address Book. Then there wasn't any other choice but to x it out but when I went to use the Group in an email it wasn't there.

if i move a message from my Thunderbird inbox on my PC to a folder in the local folders, the message moves correctly on the PC, but remains in the inbox on my iPhone.

If I delete a message from my Thunderbird inbox on my PC, it is deleted correctly on the PC and on my iPhone.

Any ideas why moving a message to a local folder is acting up suddenly!

I need to move around 9,000 emails from a business Google workspace email to a personal Gmail account. I successfully exported all 9,000 emails to a Mbox file. I added the new Gmail account I want to move the emails to and the exported file to Thunderbird and it shows over 20,000 emails in Thunderbox (even though there should only be around 9,000). I have tried moving the email file to the new email account within Thunderbird twice now. Both times it shows like it is moving the 20,000 emails but when it finishes it only moves around 1,200 emails. How do I get it to import all 9,000 of the emails that are in the exported file?

Background - my old (selfhosted IMAP) server died, I was able to recover the Maildir but for whatever reasons both dovecot and courier ignore the "message read" metadata embedded in the filenames so the local copy in Thunderbird is suddenly the most authoritative.

But every time I try to bulk copy from the old account to local folders or to my new server it fails because it tries to contact the dead server.

Looking for ways to attack this problem

I recently clicked a like on a reply to one of my questions on this help forum and then somehow I also clicked on dislike as I was scrolling through the reply so I clicked the dislike again thinking this would remove the dislike but instead it added another dislike to the person who replied to my question I did not think is was possible to add mulitple likes and dislikes to the same person but it appears this is what I have done is it possible to remove the likes and dislikes you have added and if so how do you go about removing them. Thanks.

Hello

Overnight Thunderbird has developed a major problem. The count for the number of mails in a folder is correct, as best I can tell, but when I open the folder it is either empty or has fewer mails than the count. Based on several tests, repairing sometimes adds more mails, sometimes not, but never the entire folder.

I repaired the inbox and it is now showing several mails that I deleted in the last few days (by emptying the delete folder having previously deleted them). Curiously, they’re all the same type, routine mailings about road works.

I may have backup in that I copy the entire Thunderbird folder to an external drive every morning, including today, and to Google Drive every Wednesday.

Please can you help.

Thank you

When I open up my Thunderbird to get emails I keep getting getting error code 0x80570015. I can't see attachments and cannot respond to emails. Also cannot delete emails. I Iooked it up to see how to fix it and they say to remove the "lightning" add on. When I go under tools and look for this add on, it is not there. In fact it doesn't seem that I have any add-ons. Something to do with the calendar which I don't even use. It says Thunderbird is up to date. Could you please give any advice how to fix it. Thanks, Matt

I am an office worker. I close all applications every day before I leave for home. If I forget or miss and leave Thunderbird open overnight, I do not have an internet connection the next morning and I have to reboot my machine. Any ideas as to why that might be?

I am using Thunderbird 128.7.1 on Windows, have several mailboxes (POP and Imap) with many sub-folders and large email archives (~20 years of emails) under "Local Folders". Indexing used to work fine over all those folders and I liked it a lot, in particular the timeline view on global searches.

Now, since a while (not sure for how long) indexing only looks into all my "Sent" folders, and not any of the incoming folders or local folders. I see that in all the global searches I try now. Note, whenever I archive a large amount of emails, I delete global-messages-db.sqlite and re-start TB to make sure the index gets re-built to match the real folder content. Previously global-messages-db.sqlite had a few GB in size, not it does not get larger than ~100MB.

How can I tell TB to index all folders as it used to do?

I am not receiving any emails on one particular account (I have several and the others seem to be working normally). I did receive messages yesterday on this account. I can see the messages on my phone and on the web interface and if I forward the message I can see it in the "sent" folder. What could be going on? Thanks for your help

On Thunderbird on macOS, I am trying to use a Security Device to client certificates made available by the OS for TLS authentication to IMAP servers and S/MIME signing and encryption. Under Security Devices, there is no Security Device that provides this functionality so in Security Devices I click Load and Browse... and select /Applications/Thunderbird.app/Contents/MacOS/libosclientcerts.dylib to add the appropriate security device. However, when I click okay, I get "Alert" "Unable to add module" . What am I doing wrong?

I also use libosclientcerts.dylib in Firefox just fine. Why is it not working in Thunderbird?

Dear technician,

I have configured my email account to Thunderbird mailbox, but the email sending speed is too slow and cannot be sent successfully.

When using Thunderbird mailbox mail merge plug-in, it always shows: Your email has been sent, but due to network or file access errors, the copy could not be placed in the outgoing backup folder (sent). How to set up the account to solve this problem, you can put the email into the outbox or draft box of the email account.

How to activate Thunderbird mailbox account enterprise version and enterprise version fee and daily email limit?
