Att made me change my account password. Now Thunderbird cannot access messages. I have entered the new password in out going and incoming but there seems to be more to this than that because nothing happens. Where do I have to put in new passwords? Thanks so much. Marjorie

I must be doing something wrong. I am new to thunderbird, migrated from Eudora since I can't send mail with Eudora anymore.

I tried to configure Thunderbird as much as possible like Eudora, but ... it doesn't receive nor send mail. On the surface it looks fine, it seems thunderbird logs into the server, it seems it sends mail and checks for new mail, only I don't receive anything, nor send anything even though it looks it does. So what am I doing (or is going) wrong? (I can still receive mail with Eudora and today I checked and received 54 mails, none with Thunderbird)

I'm dealing with a properly updated 'bird: 140.5.0 (32-bit) running on an equally updated Windows 10 desktop. First thing this morning, out of nowhere, I started getting an "unable to write the email to the mailbox..." message when sending, thus I could send but not save. And then I realized I wasn't receiving either, on all three accounts in my Thunderbird. I stopped everything and focused on trying to fix this. It's been an all-day, losing effort. So far.

I tried the various quick checks and fixes recommended here and there: I'm running the program as an administrator. I restarted the program. I rebooted the computer. I think I have enough disk space, but to be sure I deleted some bloat from possibly overly large files. I compacted, even though the program is configured to do that regularly. I temporarily disabled my antivirus program. I went into my webmail and deleted all messages that have arrived since my Thunderbird stopped receiving, in case one of them was corrupted. And probably some other attempts as well. Nothing has helped.

And now a second, even worse issue has fallen from the sky. Thunderbird opens. The folder list is where it always has been. The number of unopened messages in each folder is there in boldface, as always, but...the folders are all blank and I get the dreaded popup: "unable to open the summary file...." Have I lost my years' worth of carefully curated emails?

I've tried folder repair. I've deleted parent.lock. Etc. Nothing. Nothing. Nothing.

I will be super-grateful for any wisdom sent my way.

I am having a problem with receiving emails that are someone replying to an email I sent. I don't hear back from them and when I give them a call to see why they haven't responded they say, yes they have. So I go and type their name in the search bar at the very top and it shows me their responses and says that the email is in my inbox but it isn't! How do I figure out where these emails actually are and how can I get it to stop doing this?

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

Hello, I'm using the most recent version of Thunderbird on a desktop using Windows 11. Just this morning (Aug 11), all incoming email to all my four accounts are coming in with no subject or correspondents showing and when opened the email is not formatted in HTML, just plain text and lots of code. I have tried several fixes with no success: repair folders, turn off all add-ons and anti-virus protection, uninstalled and reinstalled software. Can you help, please? Thanks!

I have been using Mozilla Thunderbird for decades and they have even contributed a small amount of money to Thunderbird periodically. Just within the last two or three days all of a sudden I have been unable to send emails with my phone. I receive emails, but I do not send them. So I opened up a laptop where I did not have Thunderbird and set it up properly through Spectrum using the incoming and outgoing servers as mail.twc.com. and yes, just like on my phone. I continue to receive new emails, but even with the laptop I was unable to send an email. I received the message"send message error sending a message failed. The message could not be sent because the connection to outgoing server smtp mail.twc.com was lost in the middle of the transaction. Try again."I contacted Spectrum twice and both times they had me try to send a message through their Web server spectrum.net and that message did go through. Of course then their response is that this has to be a problem with the third-party app meaning Mozilla Thunderbird, and they can’t help with that at all. I sure would appreciate some help because I hate to walk away from Thunderbird as well as change my email address after all of these decades.

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.

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?

Following a switch off and restart triggered I think by a Windows update, Thunderbird is not displaying any messages in my Inbox, though it is showing the number of messages in the Inbox title bar. 'Drafts' and 'Sent' all display correctly, but the 'Inbox' is blank with a grey icon of an envelope and the statement: "No message found". I am an IT novice. I looked on the 'help' pages. I have checked that no filters are set. I have right-clicked on the 'Inbox' title to display the menu with 'properties' at the bottom. I have clicked on that to bring up the dialog box with the "Repair" icon. It shows 'Inbox' in the 'Name' box but I note that the 'Location' box is blank. Presumably it should not be. Presumably it should show either the location of locally stored messages on my hard drive, or the location of the messages on the email server. I am not sure which. I have found the directory on my hard drive where I believe the messages are stored locally. The size of the file suggests to me that they are all there. The periodic 'Checking for new messages' is happening, but nothing is displaying, though a check via webmail shows that new messages are arriving on the server. What should I do to get my Inbox to display correctly? With many thanks, Iain

To my new computer Thunderbird has just fetched the INBOX-mails from the IMAP-server, not my many subfolders, not the SENT-folder, not the SPAM-folder. This has previously worked when I changed to a new computer. How do I get Thunderbird to transfer these mails.

hi all today thunderbird stopped downloading messages from the mail server

a manual d/load doesn`t do anything

the mail is backed up on the server & i can`t get a d/load to happen ( manual or auto)

how to auto- clear the server so i don`t keep getting maibox full messages or is this the inbox on my computer that the message refers to

i keep deleting the junk files

I can not send out emails from Thunderbird. I get the following message "Sending of the message failed. The message could not be sent because the connection to Outgoing server (SMTP) mail.xxxx.ca timed out. Try again." I have not been able to find an answer to this problem. I hope you can help. Please note I am a Senior so please be patient with me. Thanks, Al

When sending an email using the keyboard shortcut, the settings tell me that I can set TB to give me a confirmation prompt. Why can't I get a confirmation prompt when using the Send button? Is there any way to make TB do that?

I set TB to run a spell check before sending, and that gives me an opportunity to cancel the Send operation. But it only works if the email contains a misspelling.

Thank you.
