Thunderbird Support Forum

The setup screen popped up when I tried to start Thunderbird. I had to reset Windows 10 and doing so my Thunderbird disappeared. I am using High Contrast mode and sometimes white text gets hidden in a background color. I was kind of expecting a text message. As I progressed through the set up screen I get error messages when I try to click on Done. Above the Done box is some blue text that I can't read clearly. The blue text generates a message about IMAP already being there when I click on Done. There appears to be no correct way to click on Done. When I click on Cancel my email pops up with Local Folders highlighted. When I click on Inbox it looks like every thing is back to normal. I do want to ask someone to add a vertical scrollbar to the setup screen. Otherwise I have to go through the Windows Setting screens to resize everything to get it to fit on my desktop. This also requires changing my font size for some reason. At this point I am becoming really frustrated with Windows 10 - which Mozilla has nothing to do with.

-Made custom domain through cloudfare, lets call it 'solv@xdomain.com' , fully paid for and working -Registered it through iCloud mail on my iPhone and mangaed to get it working - Decide I would like Thunderbird client as main client so download - I follow steps of generating app-specific password for thunderbird, after entering my name and email 'solv@xdomain.com' correctly. Then I generated password through iCloud for non apple app, pasted it in and tried to log in - Server error, something wrong with password etc.

I have double checked everything and even re-installed thunderbird but it still comes with a server error. What can I do to use my own email address with thunderbird? Thanks solv

I setup my account, but I keep getting a message - Login to server outlook.office365.com with username waynec67@outlook.com failed. How do I fix this?

I can't download emails and get the message "Unable to write the email to the mailbox. Make sure the file system allows you write privileges, and you have enough disk space to copy the mailbox." I know I have plenty of available disc space (>40GB) and I haven't changed anything. This happened overnight. Please help

So use to when I installed, I would loose all my folders and have to reset them up. When I downloaded the beta, all my folders on the cox server showed up as I would expect. Has this been fixed on new releases on a new version so that all I folders on the server will show up when I upgrade to the new version so I don't have to remember how to fix that? Was so pleased when I uploaded the beta version and all my folders were there, woooo hooooo.

P.S. Also love the newest version of K-9 Beta, I now use that for email on Android instead of BlueMail! Thank yo Guys, er, and Gals!

I have Thunderbird 115.9.0 (32-bit). Previously, I had no problem with the Dictionary. But now, I get no spelling suggestions at all. There is a blank space after "Language:" in the "Spelling" section of Settings > Composition

I have tried several times downloading the "English (British)" Dictionary and the Language pack In the "Add-on and Themes": in the "Dictionaries" section: "British English Dictionary (Marco Pinto)" is there and enabled. In the "Languages" section, "Language: "English" is present and enabled

When I am writing an email, clicking on the "Spelling" shows "English (United Kingdom)" with a tick next to it. I was not able to get a screenshot of this last item but I attach screenshots of all my other statements above.

What have I missed? Thanks in advance for any help.

Dear Thunderbird Support,

I installed Thunderbird and added my xfinity email account. All worked fine for half a day, then it stopped connecting while downloading a folder of files and hasn't reconnected since. The "extra" pop up window where the first time I logged into Xfinity and then used the Xfinity App for 2FA and it worked fine, now opens a window and starts with a long URL, then after approx 10 sec replaces that long url with a localhost one and the page says "Unable to connect, An error occurred during a connection to localhost."

Can't seem to get past this now. Restarted the program then restarted my Windows 10 PC, same unfortunate result. I'm afraid to remove the account because it wasn't through synchronizing one or more folders.

Thanks, Robert

I cannot get K9 to accept that I do not have a password verification for my e mail account.When K9 automatically configures my account IMAP and outgoing server it asks for password which I don't have

Bonjour Madame/Monsieur. Depuis 2 jours voici le message qui s'affiche à toutes mes tentatives de connexion à ma boite mail :

Échec de la connexion depuis le serveur imap.orange.fr avec le nom d’utilisateur robert.verger0524@orange.fr.

Que dois-je faire ? Cordialement. Dr. Robert Verger.

Since (I think) installing the latest version of TB SuperNova 115.7.0 (64-bit) emails are not stored on my MacBook. They load, I can send emails but they disappear and all my various folders over the years are empty. From Synchronization & Storage I have "Keep messages in all folders for this account on this computer" checked. When I log into my "Google Mail" account I see all some of my previous mail. Very confusing. Obviously a setting someplace but where else to look Thanks for any advice.

Fresh Thunderbird (115.7.0 (64-bit)) install on windows 11. Set up my POP3 (x4)accounts okay, but missing any form of the address book. When I click on "Tools" > "Address Book" , or hit CTRL+Shift+B nothing happens. The program is grabbing email addresses as when sending new messages I get the contacts button with previously used addresses, but no actual address book that I can add/edit addresses. I did try un-install and re-installing thinking i just had a bad install.

The second issue is that Thunderbird is no longer automatically retrieving emails on startup, even though I have the option checked for each email account. It is retrieving on the 10 minute intervals that I've set it too, but not on startup.

I'm a long, long time Thunderbird user, this is the first time I have ever had any issues. Any help would be much appreciated. Cheers

I am setting up Thunderbird on a new computer. I have installed the most recent version of TB. I have different att/yahoo emails that are separate att/yahoo accounts and not linked. When I set up the first account, it downloads all folders and emails perfectly. However, when I set up the next account, it will only download the same folders/emails from the first account. They are both set up as IMAP with unique usernames and passwords. I had the same issue when I transferred the TB profile from the old computer. I have no issues with different google email accounts. I have uninstalled TB and deleted all folders with no change when setting it up again. I have cleared all cookies on all browsers and closed them. Any solutions?

Every 2 years, when a new Ubuntu LTS version comes out, I need to migrate my cloud based mail server. After I have transferred the domains and set DNS to the new server IP, I always have the problem, that my existing thunderbird imap mail accounts don't work properly anymore. K9 mail on my android devices doesn't have this problem. Sending mails does work, but the imap connection to my mail accounts is broken. I tried using the IP of the new server instead of its DNS name, but this didn't help either. The only way that works, is to add a new account. This is very nagging as I then need to manually edit all my adapted settings and my various mail identities. Is it a generic problem with TB, possibly with the server certificates? Or is there another way to change the imap server of an existing account?

I use Owl to receive my emails on Thunderbird. This has been working fine, but stopped round about my renewal date. I have re-added all my account details and can get the data to come up, but it doesn't stay. Every time I close Thunderbird, so all the folders and emails disappear too. Please help. I have tried contacting the Owl Support several times by email, but they have not replied!

I am trying to move back to Thunderbird from Apple Mail. The issue I am having is that Thunderbird is not pulling my sent messages on my Mac or in Linux. When I used Thunderbird in the past this was not an issue. I checked the forum and my iCloud and Fastmail accounts are set up as IMAP. What has me confused is that Thunderbird pulled three messages with very old dates but nothing else.

Hi,

I just got a new laptop and installed Thunderbird, which I've had for years. Tons of contacts, using two email addresses. One is with Spectrum and the other is through Bluehost (my website).

I was able to figure out how to download the emails from Spectrum, but when I click on email, I get empty box, no details within the email. What happened?

Also, I don't have any contacts. Where did all my contacts go?

Please help. Email is my lifeblood with work. I'm also self-employed, so no technical help from employer.

Thanks so much, Patti P.S. Would love to speak to a human if at all possible. This is so challenging for me.

I don't understand inglish, sorry bonjour, je viens de changer de PC et je n'arrive pas à mettre mon compte mail live.fr dans thunderbird J'y ai des archives importantes pour moi. Pouvez-vous m'aider? merci

I have used TB for a long time now and never had this problem. If I configure it on a new PC (Win 10 Pro) to get mail from a zoho hosted account, hitting mail download generates a bit of activity at the bottom of the window but no emails downloaded (I have checked there is one there) and no errors. I've disabled AV and no change. I'd like to see the POP3 traffic to try and diagnose the problem. How do I do that please? There seem to have been various generations of how this was done and the help is confusing - I've tried what I think are latest instructions but don't see an error console. Is there simply a way of getting the traffic spat into a text file please?

I am transferring Thunderbird to a new computer (from pc to MacBook) for my grandmother and I am completely unfamiliar with the program. I was able to transfer the account via thumb drive, but when I try to send an email I am getting a message failed error. As I don't know anything about how Mozilla works and am fairly technologically illiterate, simple guidance would be greatly appreciated! I have tried to make all the settings on the new computer match the old, but am not getting anywhere. TIA!
