Thunderbird Support Forum

System specs below. Thunderbird is set with 1 account: A paid Yahoo email, with a LOT of messages (well over 36K), using IMAP (Yahoo only lets the most recent 10K come down via IMAP, sadly). Most emails do download and are correctly rendered. But around 10%, starting usually a month or so back from the high water mark of last update, show email source code (text of headers, mimeparts, etc.) for a totally different email than the one highlighted (a few days later, different sender, etc.) Checking the message on Yahoo, it renders correctly. There is no pattern to the corrupted messages: they can be from mailing lists, company marketing mails, an alert from my local town, whatever.

Once the error occurs, it is consistent across Thunderbird shut-and-restarts (still showing same wrong email source as before). Emails to either side (earlier and later) render properly in the message pane.

Double Clicking the message to it's own child pane renders a pane with Subject and From as blank, and the same email source text for a different email. Forwarding the email puts the email source code in as text (I was hoping the act of refreshing and reformatting might grab the correct content, but no).

Doing a Repair Mailbox (which seems to mean "download headers again, then download all the mail again" does seem to correct for a time (including the previously corrupted emails now rendering correctly)... but within a day or two, a new crop of messages will be corrupted, and the dance starts again.

Windows 10, 64 bit. Norton 360 set to exclude all mailbox directories. Thunderbird 115.12.2 (64-bit), though this has been happening since 110. No plugins, no extensions.

Are there diagnostic logs or other info I can share that can help us figure this out? I really like Thunderbird, but it's just unusable here. Outlook, Apple mail, other tools don't seem to have this problem.

I've been using Thunderbird for my hotmail.com and cox.net accounts for many years. Recently cox transitioned to yahoo.com with their email and users had to transition over. I was able to do this for 5 accounts - no problem. My hotmail.com was a bit more of a challenge but I was able to get it to work. Last week I started getting sign-in errors. Nothing worked and I deleted my hotmail.com address in Thunderbird figuring it would be better to just start over - wrong choice. Now I cannot even install my hotmail.com account on my Thunderbird.

I first tried the straightforward approach. Get an app password from my Microsoft account. Nest I it account actions, add email account. I added my name, email address and app password. When I hit ok a message quickly flashed saying configuration doesn't work. When I done I get a message that server already exists. I tried going to manual configuration and changed to normal password but got the message again that server exists. I went to the Outgoing server (SMTP) list but the outlook server doesn't show up.I tried using the hotmail password instead og the app password with same results. Finally I logged out of Thunderbird, turned off the two party requirement in Outlook and again tried to add the account to Thunderbird. Now I get the message 'could not get issuer fot oauth2 authentication'. I next went into manual configuration, turned authentication to 'normal password' the the hotmail account installed.

I closed Thunderbird and started again. sent a message to the hotmail account and had to reenter the password - works. Tried to send a message and was asked againgn for the app password - then it works. So all is good except when I check the server settings for smtp and IMAP, ot shows 'normal password' After strugglig for two hours I do not want to risk changing them to oauth2. Checked under 'saved logins' and the app password is shown. Is it likely that I have arrived at a stable solution? What am I risking by having the 'normal password' authentication?

The Inbox is not showing up but my Drafts is showing two emails in it, but I can not forward on do anything with them. I am on a updated Dell Studio laptop with Windows 10. I have had a lot of problems getting my email to work Optimum using suddenlink.net server. It is working well on my Mac Mini. I have been at this for two days trying to get it to work. Thanks for the work on this good software!

AOL emails won't download to TB. POP. Spent hour and a half with AOL help, reset password, checked everything, got recent emails downloaded, but still can't connect for new mail. 'Server Error" " Log-in Failed" etc. Sending mail no problem. They say TB issue. Sudden stop 6/21/24. Mozilla help site directs me to find things on PC that I can't locate or understand. Not very tech-savvy, pretty frustrated.

I have been running Thunderbird for almost seven years now, and these behaviors have persisted since day one on my laptop and desktop computer. First, I have five accounts set up. I am running two add-ons (Provider for Google Calendar, and Quicktext). I am currently running a snap version 115.12.2 of Thunderbird on both machines and they both are running Ubuntu 22.04 LTS. Plenty of RAM and plenty of free disk space.

Here are the two issues...

1. More often than not, when an email comes into one of the inboxes and I am viewing the unified inbox there are two copies of the same email. If I switch back to the actual inbox of the account it only shows the one. This is very aggravating and when you start trying the delete emails from the unified inbox it gets all hosed up and I end up having to go to each individual mailbox to delete the messages.

2. This somewhat relates to issue one... Sometimes when an email is deleted from the unified inbox, a blank record remains like in the image. This shows only one but sometimes there are multiple ones. Of course, if I go to that message's inbox it is not there.

I have tried all the common things like deleting the index files to let the indexes rebuild, comparing folders etc., and again, this has been a persistent problem since day one. Any insight or solution would be greatly appreciated.

Thank you! Mike

I have read that in earlier versions (TB 102) arrows would appear on the left of the message header indicating that a message had been replied to or forwarded. I'm using TB 115 and there are no such arrows. I tried safe mode, but that made no difference. It would be helpful to see which messages have been replied to or forwarded, and which not.

As of Sunday, Thunderbird can no longer reach my ATT server to download email. It has behaved for ten to fifteen years. Last time someone at ATT fixed it. I have been on the phone or on screen with ATT most of my waking hours since Sunday. (In the process I lost my internet, my landline, my cell connection, etc.) Everything is restored except the connection between Thunderbird and ATT. Everyone thinks changing my password will do it. Done it four times. It gets me into the ATT mail. I have replaced the password in Thunderbird settings with it to no avail. Is there anything you can think of? Not only is Thunderbird more attractive than ATT, I have thirty years of mail boxes there, a continuation from Eudora. I will appreciate your wisdom.

Greetings,

In Thunderbird 115.12.2 (64-bit) on Linux Debian 12.6, when I examine "Help -> About", cursor movement in the focused information window moves the list of messages displayed underneath in the unfocused messages window. Hopefully the image suggests the issue. Is this an OS problem or something that can be corrected in Thunderbird?

Also, I maintain several accounts, each with several folders. It would be helpful if these all stayed collapsed until selected, with a digit alongside indicating the number of unread messages in each, but recently they each seem to fully expand at inopportune times, making email management rather difficult.

Is this the result of a selectable setting somewhere, please?

When I start a email message search, I am bombarded with bad suggestions for email addresses. These include addresses from everyone I've received email from even though I have deleted these entries in collected email addresses and my personal address book.

The addresses could be from old purchases or ebay responses or anyone I've ever received an email from. I have deleted most of the emails entirely, yet I still get all these bad addresses when I search.

Is there a way to clear the history in search or remove the email addresses where I have deleted the email?

I've attached a Home Depot search as an example.

A couple of days ago I had to change my default browser from Firefox to Chrome to fix a problem on a particular company's web site. After I made Firefox the default browser again I found that every hyperlink in an email or a document that I clicked on opened Firefox at the same web page: "https://read.amazon.com/landing".

I have no idea what I might have done to create this situation, let alone how to undo it.

I am using Linux Mint with Firefox, Thunderbird and Libre Office.

Hi, Any time I'am connecting to email addresses ending by @akeonet.com (SFR compagny) on THUNDERBIRD, I'm receiving a message asking me my password imap.sfr.fr. Same to send a message exit server (STMP) smtp.sfr.fr.

Problem is the existing password is not working anymore with THUNDERBIRD but is still working with the webmail of SFR ????

I'am don't have such problem with addresses ending by @gmail !!!!!

Can you help to reconnect THUNDERBIRD to server SFR/ Neuf ?

Thank you to help me to solve the problem.

Claude

keep getting "Login to server imap.mail.yahoo.com failed." I've tried everything thru Mozilla to change passwords and tried every password possible. It's been 2 weeks no access to my emails thru Thunderbird. I'm at a loss. what can I do to get into my Thunderbird account without dumpig it all to start over?

I've had Thunderbird mail for some years but I haven't been using this computer for about 18 months. (Mac High Sierra). MacBook Pro 17-inch mid 2010 2.66 Ghz Intel core i7. 8 gb memory

I came to open Thunderbird mail today. It was all set up as before. The Yahoo accounts were fine, and Cloud. But when I opened Google it gave me: "Authorization Error. Error 400: invalid_request You can't sign in to this app because it doesn't comply with Google's OAuth 2.0 policy for keeping apps secure. You can let the app developer know that this app doesn't comply with one or more Google validation rules."

I went to Google and was able op open google mail fine as a standalone M-Gmail (https://mail.google.com/mail/u/0/#inbox)

How can I incorporate gmail into Thunderbird.?

This has happened to me on several occasions but today I was fed up with it and came here.

I completed an important message in Thunderbird (latest Windows desktop version) and saved the draft so I could read it over with the Darling Bride before sending it. When I opened the draft to go over it with her, the draft literally stopped in the middle of a word - and nothing after that had been saved!

Several carefully-worded paragraphs had simply vanished, even though I saved the draft when the message was complete. WHY is Thunderbird not saving entire messages when I finish them and hit SAVE??? One can imagine my anger and frustration of trying to recall, word for word, what I had written so I can rewrite it (and it's never as good as the original). I like the idea of Thunderbird and not using the big data-mining email apps out there... but this is ridiculous!

Hi,

I've downloaded T-bird on two computers- a windows platform and a mac. It works find on the windows platform, but on the mac, while it appears to have populated from my email account (IMAP) with no issues, the search feature always returns nothing. On the windows computer, it works fine.

If relevant, it's open on both computers at the same time, but that doesn't seem to cause any issues, as they're pulling from a web-based email account.

Any ideas about how to make the search feature work on the mac? I search for words or names that I know are there, but the results are always empty. It's important, and I need to get it up and running quickly.

Thanks in advance!

Hi, I added this https://packages.gentoo.org/packages/added.atom and in Thunderbird I do not see the summary tag data :(

Is it expected?

Hi,

I repaired my inbox yesterday. I had many messages still in that inbox but after the repair I only see 5 messages. I looked in the directory my profile points to for my email and can see a large Inbox file - but I also see a very small Inbox.msf file. It is almost like the process of rebuilding is pointing to another Inbox file. See the picture attached.

I even tried to take a previous copy of the Inbox.msf file from a backup (it was 800 kb). I deleted the old Inbox.msf file and replaced with the larger 800 kb file. When I opened Thunderbird, it started to something: "Building summary file for inbox" and about a minute later those same 5 emails show - instead of the full Inbox I would have expected.

Is there anyway I can re-associate the Inbox.msf file process rebuild/repair to the correct Inbox file (the one that is 737 meg in this case)? I sure would like to get my inbox messages back (and file them away i/o leaving them there vulnerable to this kind of problem in the future).

Thanks in advance,

Patrick

Outlook email accounts are duplicating and asking for passwords which are in the password manager. T/B does not accept the entered password. Gmail accounts are also duplicating and adding weird passwords. Just started last week. Probably has something to do with the new Microsoft Authorizarion rules. It is a mess. I have been a lifetimme used if Mozilla and Thunderbird.

Not always, but frequently when I delete an email from an inbox, the other emails are hidden for awhile. This occurs whether I am pressing Del while the email is visible, or pressing Del with the email selected in the Inbox. If, however, I immediately open another folder and then re-open the inbox, all emails are instantly visible. Am I doing something wrong, or is this a "feature"?  ;-) Regards, Dave
