Hello all:

Transferring Thunderbird from the system above to the system noted above. Follow the instructions from here on the Mozilla Support page (copied both "Thunderbird" directories into the Roaming and Local destination directories. When the destination machine installation opens, it is functional (i.e. it picks up all the existing e-mail accounts, downloads new mail, etc...). The problem starts when we get to the local folders.

All of these have a date and time appended to them in the destination installation. For example, if the original folder is "Prosperity Bank" the destination folder is labeled "Prosperity Bank (2025_09_21 23_06_33 UTC)" and will not let not populate (shows no messages inside).

As I am typing this, it seems I may have identified the problem (or at least part of it). It seems the destination system install is slowly working its way through the local folders randomly (not in alphabetically order), as it seems to be slowly populating them with the old mail stored therein on the original system. It is going very slowly. Very slowly.

Has anyone else experienced this? Is it normal? Is there any way to quickly eliminate the dates now appended to the local file names? (Visually this is very annoying and I do not want to try modifying the individual folder names yet until I'm sure its populated as much as it will populate.)

Thank you for any assistance.

Hello,

Need To Know:

I have used Thunderbird (TBird) for many years. Recently, I moved TBird data from a Dell Inspiron 530 Win 7, to Alien Arora 1250. Unfortunately, the passwords would not go, so I copy and pasted the data for 10 email addresses. All worked well, until 5 days ago when I could not log into the ISP.

Since then, 12 ISP tech support people gave me 12 different was to fix the login problem. The 'logging in' kept trying to login. The only way to stop it is to close TB and restart it. The same happens with all 10 accounts - can't login.

I followed instructions to the letter and nothing worked. Later, a tech at ISP said they have had a lot of complaints from people with Tbird and said it's Mozilla's fault. They all said they don't support Thunderbird. They only support webmail. One even suggested I delete all my cookies. Of course I'm not going to do that.

You would not believe the amount of crazy ideas I was given.

Here is the core problem:

I used both Pop and IMAP depending on the email account. TBird was great with POP and IMAP either.

I changed all the passwords as instructed. I followed the Step-x-Step settings on the ISP web site

The ISP, Rogers, took over Shaw. Rogers, I'm told, dropped support for 3rd party email clients and requires customers to create a new email on their Webmail host. Webmail is WEBmail because it is not Email.

Testing Out TBird:

1. On the old Win 7 TBird (Ver. 68.1.1 (32-bit)) Email works with both POP and IMAP settings.
2. On the new Rig, Tbird (V. 147.0 (64-bit)) worked for a while.

What Happens: -- Due to the issues, I set Tbird to not:, -- Check for new messages at startup -- Check for new messages every -- Automatically download new messages -- Fetch headers only

The two ISP are Rogers Rogers and Shaw <--- just redirects to Rogers. But webmail.shaw.ca still works.

My Rig with the issues: Alienware Aurora Desktop 1250 Intel i9 Ultra Nvidia RTS 5080 Memory 32 GB DDR5 Storage 2 TB SSD + 2Tb HDD Thunderbird Version-147.0 (64-bit)

Is the ISP correct, that Thunderbird may be the core problem?

Thanks for your volunteering - where would we be without you, ~r

I am setting up a new computer with Linux Mint and Thunderbird. I got my primary comcast.net account added in and working but when trying to add another account I get the following:

Unable to connect

The connection was refused when attempting to contact localhost.

   The site could be temporarily unavailable or too busy. Try again in a few moments.
   If you are unable to load any pages, check your computer’s network connection.
   If your computer or network is protected by a firewall or proxy, make sure that Thunderbird is permitted to access the web.

Since the first account works, I assume there is no problem with network connection, firewalls, or proxy settings. I have confirmed spellings of username and password. Any ideas?

When inserting several larger images (JPEG, 1.4 MB, 1770x2440 px, 300 dpi) directly into the message body (i.e. not as an attachment), Thunderbird crashed and the draft of the written message was not saved.

Is there a limit to the maximum size or format of an image that can be inserted directly into the body of the message?

I am using THB release 140.6.0esr/32-bit

Hello, I just moved my email host from Microsoft to Bluehost and I am having trouble getting Thunderbird set up correctly. I can send and receive from Bluehost webmail, and I can receive in Thunderbird, but not send. I can reply successfully, but all sent mail from Thunderbird shows as sent but never arrives.

I am running Windows 10 and using Thunderbird 140.7.1esr

Any help would be great. Thank you!

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.

When my message filter uses the "Reply with Template" action, the reply e-mail is always PGP encrypted, even when I do not have any public key for the recipient e-mail address. As a result, the reply e-mail is always corrupted.

I am using Thunderbird 140.7.1esr on Windows 10.

I have attached a screenshot of what the reply e-mail always looks like.

In the Template that I am using, the "encrypt" button is not selected, and in the OpenPGP menu of the Template, the "Encrypt" menu item does not have a checkmark next to it.

Does anyone know how I can get Thunderbird to send reply e-mails without using encryption?

thunderbird Is working fine, but this message crops up every few minutes, and requires 4 - 8 Cancel clicks. I've tried "Open anyway", I've deleted and reinstalled the app several times, and tried the terminal command "xattr - cr" and dragging the app into the window. Is there a proper fix for this. V. grateful for any solution. TIA Brian

Add outlook email account in Thunderbird app on Macbook does not strictly go through microsoft 2-step verification process. In stead, microsoft verification window flashes away instantly and Thunderbird window takes over. Although OAut2 is specified, the set up is not right. Sending email from outlook account takes about one minutes. Sometimes if it takes longer time, sending email will fail.

I'm trying to find the proper way to revert back to the default location for local mail message storage in TB (ver 140.7.1 esr).

Years ago I set my local message storage to a storage drive on my Win10 PC. I now want to move all of TB to a new Win11 PC but realize I have thing in 2 places - messages on my storage drive and everything else of TB in the default C: drive location.

If I simply change the Message Storage Local Directory back to the default path - will it move my current/old messages to the default location or do I have to manually move things (first or after?)?

I have many years and about 13Gb of email messages that I want to ensure I keep.

TIA

Hi there,

Is there a way to get checkboxes to select messages or at least a plan to get it in a future release? I saw that there has been an add-on in the past, but not maintained for some years and therefore not possible to use in newer versions. Yes, I know that you can select messages with ctrl and mouse click, but there are others in my family who are not familiar with it and reluctant to get used to it. (have used gmail for too long).

I do not understand how profiles work, and hence don't know how to fix my problem. I had a problem with my printer connection, and tried to solve it by rolling back my Linux O/S, (using Timeshift) to a date prior to the printer not connecting. (It didn't help.) But what it *did* do was to screw up my TB, which when I tried to open it, after the roll-back, complained that the TB profile was "newer", and I needed to create a new one. I did this, but then found that all my old emails had disappeared and it had started a complete new collection of emails, and all the mail folders had disappeared . I went back to the data backups from prior to the rollback, (using Cronopete), and was able to find the TB profile (and 5 years' worth of old emails) in the .Thunderbird folder in the Home directory. And I have pursued the profile manager in TB, and located the profile from before my roll-back. But I can't figure out how to recover this old one. I have a button "Set as Default", (I hesitated to commit to this - should I?), and another for "Launch Profile". But when I click on this last, it drops right back into the requirement to create a new profile. I already have one new profile, (which was created when I tried to sign on to TB after the roll-back.) I can't see much point in making yet another one. And I don't really understand how the data are stored in the profile in any case. (emails seem to be in a Mail folder, but are scattered about in a whole series of sub-folders and files within the Mail folder). And some of the numbered "profiles" seem to refer to things other than Thuderbird, (they lack any folder named "Mail".)

I have been using ThunderBird on Linux Mint for some time now. I am using Outlook.com for emails, calendar and contacts and I sync with another laptop and mobile phone. All fine until a few days ago when I noticed calendar events were not syncing with my phone. I found one calendar event in ThunderBird had an error when I manually synced with TbSync. The error report did not say anything specific. I deleted this calendar event and TbSync ran successfully uploading 2 events that it had not uploaded due to the calendar sync error. I then wanted to manually recreate this calendar event in ThunderBird. When I clicked on "New Event", the Calendar New Event pop-up window did not appear. When I minimised the ThunderBird window, the New Events was not behind it. The ThunderBird icon pinned to the panel had a "2" in the corner. When I hovered over the ThunderBird icon in the panel, it showed both the ThunderBird window and New Event window preview. When I selected the New Event preview window in the panel, it still did not become visible. All I could do with with New Event preview window in the panel was click in the 'X' to close it. I checked for Lightning Calendar Tab add-on updates. It was up to date. I check the settings. All OK. I disabled and enabled this add-on. Still not working. My Windows habits made me shutdown and restart my device. Still Not working. When I checked the other ThunderBird functions, New Event pop-up windows appeared for Emails and Contacts but not Tasks which had the same symptoms as the Calendar.

Bonjour Désolée, je ne sais pas écrire en Anglais, mais je pose ma question ici, au cas où une bonne âme pourrait m'aider. Je suis nulle en informatique, le minimum... -Mon mail ' nadetted@free.fr ' a basculé sur ZIMBRA, et je n'aime pas du tout fonctionner avec.

                 Les 2 adresses mails sont les mêmes, et je me perds dans les mots de passe.

-Sur l'ordi, mes mails vont jusqu'au 29 novembre ? .et on me demande "Saisissez votre mot de passe pour nadetted sur imap.free.fr : *alors que je n'en ai jamais mis, et accédais direct à mes mails.

-Ensuite j'ai cela  :: "échec de la connexion depuis le serveur imap.free.fr avec le nom d’utilisateur nadetted"

                                 *le serveur IMAP .free serait déconnecté !?

-Sur le GSM, je vois mes mailsl jusqu'au 15 décembre 2025 ?  !

-J'arrive à voir mes mails sur Zimbra, mais je voudrais sortir de là et récupérer *sans pertes de dossiers etc, ma boîte mail d'avant  :: nadetted@free.fr classique, que j'ai depuis très longtemps. Cela est-il possible SVP ? -Depuis, j'ai de gros soucis de connexion avec mes contacts et RV médicaux, nous sommes des personnes âgées, et personne pour nous conseiller. Je pense à un Bug, ou une mise à jour défaillante ? Je suis en W10

-J'espère que quelqu'un pourra me lire, voir me contacter en Français, sur mon mail de secours : [edited from public] @laposte.net ou [edited from public community support forum] @free.fr Bien à vous Merci Mme Benard France

Sorry but I find carrier pigeons easier than computers and no I don't have any. I am trying to get a second email account sorted as the first one has been disconnected (old supplier) even though new emails sent to the old address show up on thunderbird. Online advice on how to do this does not work, as the information that should be on screen is not there. Oddly enough the new email address has allowed me here, does this mean that the new email address is now working? Many thanks

Hello,

After today's Thunderbird update for Windows 11, over half of the folders in the local folder are no longer displayed. However, the folders are present in the backup folder on an external hard drive.

What's causing this?
