Thunderbird コミュニティフォーラム

Running Thunderbird 128.14.0esr (64-bit) via 64 bit Win11 Pro v. 25H2 on a Dell Inspiron 16 plus, Core i7-12700H @ 2.3 GHz, 24 MB cache, 40 Gb RAM, 877 Gb free on a 1.8 Tb Crucial T710 NVMe SSD drive. Integrated Intel Iris Xe graphics using 20 Gb shared RAM.

I have 5 email accounts (AOL = Yahoo, Yahoo, GMail, Verizon = Yahoo & MSN) each with a distinct IMAP server description. I also had my daughter's AOL account in the same TB profile.

On 5/9/2026, I foolishly entered my credentials in an AOL request for verification of her account (to allow TB access). As result, my jawarters@aol.com account and her jmwarters@aol.com account somehow became linked. Her email account in TB now contained only messages which were duplicated in my email account.

I deleted her existing jmwarters@aol.com mailbox and attempted to recreate it in Account Settings. Despite entering distinct IMAP settings (user name = jawarters@aol.com, imap.aol.com, port 993 and user name = jmwarters@aol.com, imap.aol.com, port 993) and having distinct SMTP settings with the user name in the Description, the recreated account again downloaded my emails into her TB account. The same happened when I opened TB on my desktop.

Interestingly, TB for Android v. 18 kept both accounts separate. I attach a copy of the TB Android k9s settings file which shows the same IMAP and SMTP settings as the laptop / desktop TB.

Help solve my self-imposed problem! Jim W

This is what I get when I click on email link. I can't delete it. This has to be solved before I can get to my second problem https://webmail.spectrum.net/mail? context_token=eyJza3NpZCI6ImNvbnRleHRfdG9rZW5fc2lnbl9rZXlzZXQiLCJza2lkIjoiNmJkYzZiMTEtZjBiZS00ZGFlLTliOWUtY2RkMGMyNWE5ZmUyXzIwMjAtMDEtMjRUMDcuNDIuNDQuMzQwWiIsInNlY3BvbCI6ImNvbnRleHRfdG9rZW4iLCJraWQiOiI2YmRjNmIxMS1mMGJlLTRkYWUtOWI5ZS1jZGQwYzI1YTlmZTJfMjAyMC0wMS0yNFQwNy40Mi40NC4zNDBaIiwia2V5VHlwZSI6IlJTQSIsImFsZyI6IlJTMjU2IiwianRpIjoiYWU2MzMwZDYtNTBlZi00Mjk3LThlOTMtZDUxOWVjZmMxMjdkIn0.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.SkxhnFtRLxHTpXXn5_kDX8nBISuPu3wdpoNFwTKLtmUadL29D40rNMHlmEOOa2LbGFVi8qlEWnscUMV8WXGLF02RFhSsEMFtBbXGpB9XUy6q_YW5FRJo1su5AJxboh1LMastJ39rdqnooQsnvA5_Mmy4NDBZrb1bQCmzXn3wiLsiBDMxorQ8Kk45CEWL6Bz09Z8EltuEQ2yVN3FGTGqAeU2i5-qNv12kzgimIu4TbDyE2DIi6_AKenLGc1kXlcZ8oxGjUEbJm1AThmpNbGF9WJ7d55_JQyfGWvEMIYNOtAiPaNNRCF1AlcBP3TAH34L1uI49Ve6C0SvidbRu2jYDuQ&referrerAppVisitId=202601311716P-753ab3c2-c22c-44cd-865d-2b77307fabfa&referrerAppName=SpecNet&referrerAppType=Web

I have two computers, both Lenovo. One is an older model running Ubuntu linux and the other is a newer one running Windows 11 and Ubuntu WSL. The plan is to move from the older to the newer. The older model has Thunderbird 140.10.1 esr (64Bit) and I have no problem with it. The newer one came with Windows 11 and Thunderbird 150.0.1 (64Bit) installed. I want to set up the newer computer with the same complement of email accounts as the older. This complement of accounts includes a gmail account, a yahoo account and an account that existed on comcast.net before being moved to yahoo. The latter still retains its comcast.net identity, but is served by yahoo. To support this account, it was necessary to provide Thunderbird 140 with the comcast.net email address, but configure it with yahoo entities underneath. However, this same process does not appear to be supported by Thunderbird 150. It seems to insist on using comcast.net entities, which do not exist anymore. My question is, am I correct in this conclusion, or is there a way, which I have not discovered, to configure the account to work on Thunderbird 150? If so, what might it be? One final note, I am not likely to be unique in the comcast.net issue. I suspect there may be thousands of us.

I can receive outlook e-mail but I cannot send from Thunderbird. I am asked for a password for the specific Microsoft server. I enter my Microsoft account password but this does not work. Security setting is STARTTLS withNormal Password authentification. My other Thunderbird non-MS e-mails are problem free.

Email will not send. Message-- "Sending of the message failed. An error occurred while sending mail. The mail server responded: Email rejected. Please verify that your email address is correct in your account settings and try again." I am not sending to another person but testing with my personal email. Thank you.

Hi, I use thunderbird as both POP and IMAP through gmail. I keep all my emails on my POP thunderbird desktop client. I use IMAP on my thunderbird laptop client, iPhone, iPad via Apple mail when remote, then download the emails to my desktop.

What I want to do is read emails and set them to archive on my IMA laptop, iPhone, iPad. I know Gmail tags the archived emails. How do I stop thunderbird from downloading the archived emails to my POP thunderbird desktop client?

Thanks! Art

I have connected a Google Workspace (Gmail) account to Thunderbird, let's call it scott.harper@myorg.org. I am able to send, receive, and reply from this account as expected.

In my Google Workspace configuration, I have an alias address forwarded to my account, let's call it info@myorg.org. I receive messages addressed to "info" just fine. But when I send or reply to messages addressed to "info", I'm running into a problem.

In the Account Setting I opened Manage Identities, and added info@myorg.org as an alternate identity. I then edited the Private Data for that identity so that the "Reply from this identity when delivery headers match" option is checked, and set to match info@myorg.org. See attached image.

When I reply to an incoming message, the From field appears to be (sort of) correct... it shows from info@myorg.org, but next to it (in italics) is the primary account identity, scott.harper@myorg.org. See the other attached image. This is also the case when I compose a new message and select the info identity.

In both cases, when the message arrives at the destination inbox, it is from scott.harper@myorg.org instead of "info".

I'm assuming I don't have the matching rule, or some other setting configured correctly. Would appreciate any other tips/ideas.

When emails arrive it shows the number received in bold in my inbox. Since the last update instead of the new emails being listed at the top of my inbox they disappear. I then have to search through all the emails listed at the top of my inbox to find out if the new emails have been added to one of those. How do I get back to having all new emails listed at the top of my inbox.

Hi... so, when I realized that Thunderbird was not able to access Outlook accounts successfully about two years ago, I was offered the opportunity to try Owl as an add-in, which did a splendid job at the time for accessing my Outlook email and saving it/using it within Thunderbird.

But now it's my understanding that Thunderbird supports Outlook email natively, and I've dumped Owl (including turning it off as an add-on within the software), and I cannot receive emails. I tried resetting the password using the method of "deleting the password from the passwords list so that Thunderbird asks for it the next time", but it continues to check for the email at that address, tells me there isn't anything to download, and won't import the mail. I have to be missing something simple, but I cannot put my finger on it.

I've tried a couple of Reddit methods, also no help. Any ideas?

Thanks!

Hi, my folders have disappeared, apart from my inbox - including sent, junk, deleted. How do I recover them please? I've tried the suggestions from Google, but nothing works.

Also, as a separate issue, I can't now send or receive emails from my iPhone, but can from my Mac? On my phone, I get a message saying that the server is not responding. I have tried entering my server details but it doesn't work. The message says 'bad certificate format - 9,808'. This happened overnight and I hadn't changed anything. How do I fix this please, in order to send and receive messages on my phone.

In Thunderbird all of a sudden my sent e-mails are going in to the sent box of ANOTHER e-mail address I have on Thunderbird. I looked at some similar posts and think my settings are correct but obviously not. Please help! Thanks, Adam

Die Servereinstellung ist: imap.vodafonemail.de

Bei einem zweiten eingebundenen Mailkonto funktioniert Thunderbird einwandfrei.

Перестали отправляться письма с почтового ящика gmail.com. Соединение с сервером исходящей почты не устанавливается. Разные порты и способы шифрования уже пробовал. помогите решить проблему. Спасибо.

Hi, very nice of you to listen to my problem. It already startet some days ago when I realised that it took very much time to receive mails, in some the content still kept hidden. To work with the about 60 mails listed in the Income-folder, and select some to read the text I was surprised to realize, that in the next moment the folder was empty, none of the mails could be seen on my Windows laptop. I had to switch to the mail-server with Vodafone to see me mails. This situation occured with all folders on 2 Laptops with Windows 10 and windows 11. What could I do ?

Good afternoon.

The message was composed using a translator I have 3 mail for work. 1 personal, 2 shared There are no problems with my personal email. I can't send messages from two other emails, and I get an error

Error translation "Error sending message. Error sending mail. Mail server responded: Error: send AUTH command first. 1777978756-Gxds2c0SZiE0-r8k7j8Ju. Make sure the email address you specified in your account settings is correct and try again."
