Thunderbird-Hilfeforum

I have Thunderbird 115.9.0 64 bit on the 2nd latest version of Ubuntu Linux and by second latest I mean it is still supported even though there is a new version available. Several months ago there was a password problem with my internet account preventing me from logging into my internet/email service and all my devices could not send or recieve emails. I changed my password on my cell, my Windows 10 computers and they worked fine. My Thunderbird on my Ubuntu on the other hand rejected my password and I also checked all of my port and server settings with the help of my internet service provider tech support including comparing settings from other email clients. Still no password being accepted. My internet/email service provider tech agent suggested removing my account from my client and reentering it and this worked.

Several months later I changed my main email passwords again on incoming mail and outgoing mail servers on my account, verified my port settings are correct, which they were including the type of security and protocols used. When I select the desktop icon I get prompted to enter my main password and hit enter and the window keeps reoccurring as if it has rejected my password. I select cancel allowing me to enter and again clear and reenter password and again it is rejected. I removed my account (I think) and go through the motions of reinstalling my account and get a pop-up indicating the server already exists which puzzles me. Ports, security settings, password are all correct and tested on other devices. I can even use a browser and log onto my internet service providers server and access my account and my password works but not on my Thunderbird. Should I consider uninstalling and then reinstalling my Thunderbird on my Ubuntu? I think by mistake I deleted all of my emails BUT I have selected IMAP so my emails I want are still on my service providers server. IF I uninstall and reinstall how do I save my contact list. This I Inoticed is still intact. Suggestions please?

I'm getting a "nonoverridable TLS error" message when Thunderbird first opens. Also, new emails won't download into my IMAP account. I've tried adjusting the incoming and outgoing server port settings and even turning off the antivirus and phishing email scanners. Nothing works. It's now 1:59 PM on a Thursday afternoon and I've received no new emails since 11:20 AM. Please give me security settings that will work.

Occasionally I will see a set of Email messages that look exactly like the one in the attachment in the message body window. When I look at them on another client, they are fine, so I think they get downloaded to my Thunderbird incorrectly. I have about 10 or 12 messages that look like this (no change at all between messages).

Two questions:

1. Is this a problem others see (I only get it once in a while, both in the beta that I stopped using and in the current version).

2. When this does happen to me, what can I do to refresh these messages? I have not found anything in any of the menus that looks like it would help. I have cleared cache.

Thank you.

Dear reciever. After years of using TB and what we do think is a productive mail-tool that works for the benefits we are looking for has worked. However, the last 115- constantly freezing and shuts down. This is very annoying. It freezes at some folders from the main email-client- as we have deleted older folders integrated with this. But the problems remains. . We have done everything in our knowledge of the program but still no approvement. . At this point we are using Outlook..would be grateful to have some answers and possible sollutions for this issue. . Thanks in advance and keep up the great work U are doing. :-)

Hello, I have the following problem with the current version of Thunderbird (115.9.0 64-bit "Supernova"):

When writing an e-mail (no matter if only HTML format, or HTML and plain text) no list items are displayed (neither unsorted nor numbered).

Everything else, such as inserting tables, smileys, etc. works.

If I create a document with several list elements and sub-elements (indented elements) in Word as a test and copy this into the message in Thunderbird, the list elements are displayed from the second level onwards.

Even if I insert the whole thing as HTML code (ul, ol, li, ...) the same thing happens.

It is a fresh installation. I wanted to switch from Outlook to Thunderbird. However, this is really suboptimal:-(

Can anyone help? Many thanks and best regards Patrick

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 live in Canada. I cannot open a yahoo.com account with Thunderbird. The account is recognized without any problem, but when I try to connect to the account, Thunderbird opens a Rogers dialog box which does not recognize the yahoo.com account ID.

When I create a new folder in Local Folders, the new folder shows in the list and also appears in the local directory. However, if I close and then reopen TB, the newly created folder does not show in the list of folders in the Local Folder even though it still appears in the local directory, and I can see that the new folder contains data by the file size. I still have old sub-folders that I created some time ago available as normal in the Local Folder and I'm wondering if the issue may have been caused by switching from pop3 to imap a while ago as the folders I can still see were created prior to the change - but I'm guessing. Can anyone please suggest how to get the Local Folder to show the invisible folders within it after I restart? Thanks. I'm using version 115.9.0 (32-bit) on windows 10.

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

When I send email with an attachment (not very large attachment) it takes forever and then I eventually get a message back that the out going server has timed out and the message is then automatically saved in my Draft folder. However, it seems the message and attachment are actually sent and received by the recipient. Is the system not recognizing that the message is complete and just stays in the send mode until the server times out?

All of a sudden a number of emails are arriving with the correct subject line but the sender is listed as HotelMaven, with whom I do correspond. The emails are forwarded from my billsteiner@duck.com address. The sender, when viewed with BlueMail on my phone and tablet, is correct, so this is a Thunderbird issue.

Also, at the same time, Thunderbird began asking me for my password every time I open it. This has never happened before.

My Thunderbird email is bill@kikibobo.xyz. You can also reach me at wssteiner@yahoo.com. Thanks for your help. Bill Steiner

I have configured 2 mailboxes in Thunderbird sent some test mails to see if it is working. Now everything works great, but somewhere there is a mail which Thunderbird tries to send out. Unfortunately it looks like the mail is created with mail account 1 and Thunderbird tries to send it with mail account 2. Of course the mail server denies to sent the mail, because the mail address is unknown to him. I checked all outboxes in Thunderbird and at the webinterfaces of the 2 mailboxes and found nothing. I removed all mail boxes and smtp configurations from Thunderbird and uninstalled it. After new installation I still facing the issue. Where can I find the mail Thunderbird is trying to send?

Since a week or two, Thunderbird displays all emails, in all accounts, in all boxes (in, sent, drafts, deleted, etc) as dating from "June". An email received 1 March 2024 is dated 01.06.2024; the previous email (of 29 February 2024) is displayed as 29.06.2024 (see screenshots). I have emails form "31.06.2024", "31.06.2023", "31.06.2022", and so on. It continues through all emails, down to the oldest one I am keeping of 25 October 2013, displayed as 25.06.2013.

When I open a mail in a separate tab or window, the same 'June' date is there. The correcte data information is not lost: I can still correctly sort my emails on date and when I forward an email, it contains the corrected date.

The problem persisted after update to the latest version (115.9.0). Mac Monterrey 12.7.3.

In the "Find / Search" menu, files are concatenated by subject. This leads to incorrect date ordering, so sometimes impossible or very difficult to locate messages. It would be helpfull if we could de-activate this concatenated view in search option, as we can do in the main Inbox window, showing all messages by date only, and not concatenated by Subject.

Thanks for your attention. [removed email and phone# from support forum]

Until just a couple of days ago, I was able to compose a new email with Thunderbird on any of the six accounts I have on my Win10 desktop. Suddenly, the nice blue "New Email" button at the top of my folders has VANISHED and there is no way to create a new email! I can reply to emails, but I can't compose a new one!

I don't know if a fix is in the works, but for now: how do I downgrade to a previous version that I can use to send new mail? I'm at a standstill here!

Thank you!

Hi,

I'm not sure what I did but I can no longer see the headers of any of my messages. Setting headers to all doesn't change anything. All I see are the columns at the top, then the message immediately. I don't see the To: CC: etc.

I'm pretty sure I accidentally flipped a setting but I'm not sure which one. If this seems familiar to someone, let me know!

Thanks,

L

This the message I keep getting is - Sending of password for user thehawkesr@xplornet.ca did not succeed. Mail server pop.xplornet.ca responded: [SYS/TEMP] Temporary authentication failure. [imap-p6-05:2024-02-22 18:23:45]

A number of users have asked how to delete duplicate T'bird folders, and are told it can't be done. I have three Draft folders under my Inbox folder, and two other duplicates under other T'bird main folders. Several suggestions on the T'bird help site and on Google/Bing searches don't work.

Can't this be fixed? It's an old problem.

Hello,

Been using Thunderbird for years without any issues. Since yesterday it simply keeps freezing after startup and checking email. OS OpenSuSE Tumbleweed, Thunderbird 115.8.1.

- Cleaned up the inbox - Started in safe mode - removed add-ons

Nothing worked. Thunderbird simply freezes and has to be killed. In essence it has become unworkable.

What I notice is, I can start Thunderbird without being connected to the internet. It does not freeze. As soon as it starts pulling emails, it then freezes again.

Any hints?

Thank you in advance.

Regards Norbert

I have about 30,000 messages in a local folder on TB. I need to move them to an IMAP folder on my outlook.com account. I have been able to move some but TB just stops moving the files randomly. I have tried: creating a new TB profile Moving small batches Creating a new destination folder on the IMAP account Granting all permissions to destination folder Reindexing TB Compacting the Local folder Checking/Changing SMTP server settings Read everything I could find in various forums There are 'services' that claim to do this for you but require me to grant permissions I am uncomfortable with Thanks for any wisdom you can offer to resolve this.
