Thunderbird Community Forum

Thank you for the advice on copying the Thunderbird folder, which I have done. However, what is failing is the adding of further existing email accounts. I enter the Account name, the email address and the password but I still get Authentication error. I have, after some difficulty, succeeded in adding five accounts with three different hosts. The further accounts I wish to add use two of the hosts of the successful additions.

Hallo,

ich benutze Thunderbird 154.0 unter Windows 11 Pro, aktuelle Updates. Seit geraumer Zeit bekam ich die Meldung, dass Ordner Posteingang nicht komprimiert werden kann, weil er ungültige Daten enthält. Das habe ich heute abgeklemmt, indem ich die automatische Komprimierung abgeschaltet habe. Danach war eigentlich alles gut und ich hätte besser nichts mehr machen sollen. Aber dann entdeckte ich den Button "Ordner reparieren". Nachdem ich den geklickt habe, werden mir im Posteingang keine Mails mehr angezeigt, Anzahl = 0, Größe auf Datenträger jedoch 2,3 GB. Die Daten scheinen noch vorhanden zu sein, nur die Anzeige scheitert. Im Papierkorb sind die vermissten Mails auch nicht zu finden. Alle anderen Ordner sind inhaltlich ok. Ich habe eine 5 Tage alte Sicherung, die ich auf einem anderen Windows-11-Rechner mit frischer Thunderbird-Installation eingespielt habe. Leider zeigt sich dort nun das identische Problem. Hat jemand eine Idee?

Viele Grüße Peter

I bought a new computer and want to transfer my emails, calendar and anything else to start using Thunderbird and lightning. I don't want to lose any information. I hope it will be seamless as I use it for business. Both Computers are Dell Laptop with Ubuntu . I am just really old and not too savvy with tech stuff. Will you help me make the necessary transfers? Ever grateful...Thanks, Frances

As above, is there any EASY way to edit the Subject line on a received email. These days, most accounts are via email, and currently if I receive a bill for payment, I have to add an XNote or something similar, to note that I have paid, which means that you then have to open that email, to see it... Would be SO much easier, if I could just add a note to the subject line. Realise that you can (laboriously) go through the actual mail files and edit/create a script to do this, but before I go through the process, was thinking there must be an easier way??

Thanks,

I have been using the INBOX that is under my email address. This worked for years except one time before when the same thing happened where the messages are from years ago. I have to go further down to use ALLMAIL to get the current messages. The INBOX shows "3" while the ALLMAIL shows 5,626.

So, the INPUT is not current as before but old messages. How do I fix this?

Thanks,

Eddie

I had Thunderbird on my Windows 10 computer. I bought a new Windows 11 computer and downloaded Thunderbird. When I try to set up my email account, I provide my full name (not my Thunderbird user name) and email address. The next screen has the message "Configuration found in Mozilla ISPDB ". I clicked on IMAP and hit continue. The next screen I type in my password for my Spectrum mail account. I have confirmed that the password works went I log onto the Spectrum website. The next screen has the Authentication error "Unable to log in at server. Probably wrong configuration, username or password.". I've also tried using my Thunderbird user name and Password instead of my full name and Spectrum password with the same results. I know my Thunderbird user name is correct but I can't be 100% sure that my Thunderbird password is correct.

I'm not sure if this matters but my email has the has the extension ----@socal.rr.com. This was assigned to me by my original email provider, which was Time Warner Cable. Spectrum bought Time Warner Cable a few years ago and I think Spectrum uses a different extension.

What is the best way in TB of organising the storage of email messages on my local storage device:

• Many folders/subfolders, each containing a limited number of messages?
• Few / One Archive folder containing all messages, each message tagged with one or more tags for easy search/retrieval?

I would prefer the latter, but I am unsure if there are any limitations to how many messages that can be stored in one folder i TB.

• Are there any practical limitations regarding the no. of messages in one folder?

I recently got a notification that a Thunderbird update was available, so the update was downloaded and installed.

Next I went to my inbox to tidy it up, by deleting some items and archiving some that I wanted to keep. On looking at the 2026 archive none of the items where found.

Why has this happened and is there any FIX ?

I am not able to receive or send emails using my wifi, but can using data (same provider). I have queried this with my email host and wifi provider and both have said there is no issue on their end that would block these actions. The email host suggested I change port 465 to 587 for outgoing to see if that made a difference. It did not.

This issue is occurring on the web platform as well as the android app.

The error message in account setting is: an error occurred connecting to gsyd1001.siteground.net:993."

I apologize for the subject line, but there is no better way to describe the problem....

I've been using Thunderbird for a few months now and it has mostly worked well. Then this afternoon I was reading my mail in the Unified Inbox and I noticed something very odd. I had a number of emails showing in the header list with the same "From" and various subject lines. On the face of it, that wouldn't describe any weird behavior except that I noticed the subject lines absolutely didn't match the "From" information.

As I would go to read these emails, the email itself would be correct in the preview pane -- including showing the correct sender name and email -- but the "From" information in the header list pane would still be wrong.

I'm sorry that I can't post a screenshot to make this more clear because there is just too much personal information on screen. But these emails are from several different senders, received by several different email accounts. Everything is correct except that the "From" shown in the header pane is wrong. This is very obvious to me because I normally run entirely in the Unified Inbox with the emails sorted by the "From" information

One example is an email that is actually from "U.S. Department of Veterans Affairs <do-not-reply@notifications.va.gov>" which Thunderbird displays correctly in the preview pane (where I usually read my emails) and if I open the email itself, but the header pane says this email is From "Prepper-co <joshua@prepper-co.com>"

Another example is an email that is actually from "USPS Customer Support <uspscustomersupport@usps.gov>" but the header pane says it is from "Rainier Arms <sales@rainierarms.com" < p></sales@rainierarms.com">

These two examples were received in different email accounts that aren't even on the same server. I have other emails from these same senders that are shown correctly

I found this problem while using 150.0 (64-bit), which said 150.0.1 was available, so I restarted Thunderbird and it updated to 150.0.1 (64-bit) but the problem is the same.

Hello all,

Apologies if this is going over old ground. I've tried the usual Repair Folder fix without success and I'm cautious about trying anything further without some expert input for fear of doing more damage.

Thunderbird version: 140.12.1esr (64-bit) Windows version: 11 Server type: POP, messages not left on server Inbox " Folder properties" reports: 16384 messages. 13.8GB on disk

The Entire contents of Inbox disappeared after the following sequence of actions: 1. Tagging a selection of messages (in Inbox). 2. Making only those tagged messages visible (using Quick Filter). 3. Selecting all of the visible messages (select first, shift-select last). 4. Deleting the selected messages (Del key) The intended messages were successfully moved to the Deleted folder.

The Inbox now appeared empty. At this point only tagged messages were set to be visible but these had been deleted so an empty Inbox pane seemed correct. Resetting the tags visibility of Quick Filter did not make the messages reappear.

The messages are however visible and openable when doing either a straight folder search or when using a search folder. Inbox Folder Properties reports that the messages are still present and the reported size on disk seems appropriate for the number of messages.

Messages in all of the other folders are visible.

At this point I did a complete Export of the profile. When I discovered that Windows would not recognise the resulting .zip file I also did a straight copy of the Inbox file within the profile folder to a safe location (I understand that the export .zip file is intended for re-import to Thunderbird and that Windows might not recognise it).

I then did a Repair Folder (within Folder Properties dialogue). This made no difference although the size of the Inbox.msf file reduced dramatically (I didn't make a note of the before and after sizes).

I then quit and restarted Thunderbird several times. This at first made no difference. After perhaps 3 or 4 restarts however a relatively small number of files have reappeared in Inbox (a tiny percentage of the correct total). Curiously, most of these (but not all) are marked as spam. Ordinarily I would delete all messages marked as spam but there are probably some that I have missed. It looks rather as if the files which are now visible in Inbox are ALL of the spam messages plus a handful of others. Of the 172 messages which are now visible they were initially correctly reported in the folder pane as being 172 unread messages.

Another strange thing is that when selecting the Inbox on the folder pane, the small number of messages which become visible only appear after a delay of perhaps 10 seconds (previously this was instantaneous). When selecting any other folder, the messages are displayed instantly.

I'm not quite sure what best to do next. I haven't yet tried deleting the Inbox.msf file. Any wisdom will be gratefully received.

Thanks in advance.

Hi

Just checking when ThunderMail and Pro will be available? I'm in need of email services for my small business and just don't want to subscribe to Google. I love Thunderbird, glad it survived so many transformations over decades and would like my subscription contribute to further development.

Can you, please provide me with at least estimated timeline?

Thank you S

Prelude:

1. I have several email addresses in Thunderbird.

ISSUE:

1. One address, the first on the list, Draft folder shows "1"
2. View email Shows "No message found"

QUESTION: I like to keep a tidy Thunderbird - how might I fix this issue?

Thanks for the read, ~r BTW - this seems to be the last of the gremlins since my migrating - - Thunderbird - - Yea! :)

After I migrated everything to a different computer, 'Local folders' no longer appears in the side bar, so I cannot archive messages locally.

Can some kind person please help me to reinstate it?

For the second time today, I lost the entire body of a rather detailed email I was composing for two different glitches. When I started to reconstruct the first I was hitting cntl-S frequently. I relaxed a little for the second and was about to save, but I got a message about the attachment from my drive that I was forwarding, and the entire body was again lost.

From the posts I've read, it appears I'm not alone. Unclear what triggers the saving of a draft, but is there a way to increase the frequency? Between the two I lost today, I wasted over an hour and lost some of the original thinking.

I searched the setting help, but didn't find anything.

Thanks! Bob

I'm new to Thunderbird so can you explain what is the status of a Local Folder, please. Does it count against the email allowance? and How can I move emails from a Local Folder back to the main folders, please?
