Gmail has been deleting all my saved emails in sent and folders! If I download Tbird will this be a clean break with Google and Apple or does Tbird sync to these platforms too. I've tried to get to the bottom of this problem but there is no relevant setting. I'm disgusted, Google and Apple want to control my life.

Hello

i am struggling with TB as it always uses the default email of a server account.

Instead, i would like to use different accounts based on the recipients

I could not find an extension with this behavior.

For example, I would like all email exchanged (sent & received) to a domain ( @thatcompany.com ) to use a given account alias (myalias.email@proton.me)

Thanks for all assistance

I get a message saying "The certificate is invalid." And I am currently unable to receive emails. When I open the server settings screen, it says "The certificate exception already exists."

I just added two new email accounts to my Thunderbird installation, which has been working with three accounts flawlessly for years. All my accounts are POP/SMTP.

Both the new emails are Google Workspace accounts for an in-home business. One uses (my) name@(domain) as the account name, the other uses info@(domain). The account using my name works fine, sending and receiving. But the info@ account does not display a Sent folder, and will not send messages. It looks as if it does, but they never show up. I checked the Account Settings and the two new ones are set up identically, and just like the other accounts that have been working just fine. Any ideas? Many thanks in advance.

Linux Mint 22.3, Cinnamon Thunderbird 153.0 esr

clicking on 'get messages' produces no response. zero. Nothing happens. two email accounts are affected.

Consistently Reproducible.

On Saturday morning 27 June 2026 I tried to login my Orcon email account via Thunderbird (which I have been using for a long time). But my login didn't work, I got a message saying "login to POP3.orcon.net.nz with username habitation failed." On 30th June 2026 I reported the problem to Orcon.

Orcon gave me the following settings for Thunderbird. I have done that and even made a new account: Incoming Server Type: IMAP Mail Server: imap.orcon.net.nz Port: 143 SSL: Off Authentication: On (username and password required)

Outgoing SMTP Server: Mail Server: smtp.orcon.net.nz Port: 25 SSL: Off Authentication: Off

Since then I have spent many hours and going around in circles with Orcon's Technical Support to resolve this, but no luck. They blame Thunderbird. I used Thunderbird Troubleshoot Mode. The message that comes up reads: login to server mail orcon.net.nz with username habitation failed. Please can you check that your server settings above are correct? And if there is a bug? Irma

Steps to reproduce:

Open Thunderbird. Account settings: Check "Check for new messages every 10 minutes". Keep Thunderbird running forever.

Actual results:

Sometimes Thunderbird stops checking messages for no reason. No checks are done for many days.

Expected results:

It should always check messages every 10 minutes, keep checking forever.

I was asked to post this here in https://bugzilla.mozilla.org/show_bug.cgi?id=2057745

I have 13 email accounts in Thunderbird. Most of the emails work flawlessly. However, in some accounts , before I read them, the original emails are "automatically" duplicated in other folders (for instance, "important", and or "save" folders). After reading the emails in my inbox, I have to open each folder where the duplicates are and wait for the emails to disappear "automatically". It's a pain b/c the folders are hi-lighted and therefore I can't tell if I received a new email in my inbox or is it an old one I just forgot to delete in another folder. How can I stop this from happening?

Steps:

1. Email received in inbox; inbox high-lighted in blue 2. Open inbox in order to see emails, some folders (on the right-hand side) are also high-lighted in blue. The contain duplicates of emails in the inbox. 3. Deal with emails in inbox (open, read, keep, file, delete) 4. Some folders are still high-lighted in blue ( for instance, in uploaded image "all mail" and important") 5. Open high-lighted folders which deletes folders that were deleted in the inbox or if not deleted in the inbox, emails remain in the folder but the boldness turns off and the folder is no longer highlighted in blue. How do I stop the original emails from duplicating to other folders?

Hi. My main email address was accidently removed. All my previous emails are stored locally thanks to Thunderbird IMAP syncing up to now. I'm currently in touch with my ISP in order to restore my email address. This will be done in a few days : I am going to get my email address back, but all the emails on the servers will not be restored. Therefore, when the server is restored, it will be empty.

I fear that when it's done, during the next IMAP sync, my Thunderbird will delete all local emails.

What can I do to prevent that, or circumvent it ? I would like for the local state to be uploaded to the server, not the distant state to delete everything locally.

I retrieve email from two different servers, one is mine, one for work, All of a sudden last night I got a spam email from my personal email server, that kept coming in over 100 times, but no other email. My work email is fine. I contacted the hosting company for that server, who was supposed to blacklist that spam address, (my Thunderbird junk button wouldn't do it), but I'm still getting those emails only. Thunderbird tells me there are 110 emails (and counting) on the server, but won't retrieve them. I can see them on my phone, just not my desktop. (I have the phone set to leave emails on the server until I retrieve them with the desktop). I thought maybe it was because I hadn't cleared out my Inbox for a while, so I deleted about half of the 30k emails that were in the Inbox folder, but it didn't make any difference. It won't compact because I keep getting an error that says some other operation is in progress, but nothing is. None of my settings have changed, and I'm still downloading what I think are copies of that spam email, since they all have the exact same Send time. My Thunderbird version is current, v 140-13 oesr 32-bit, on Windows 10. What can I do, thank you in advance. Long time Tbird user, rarely any problems. Image of some of the copies of the spam email.

TalkTalk have outsourced their email to Everymail. We use Thunderbird as our e, Mail client on a pc. We have stopped getting email and can’t send any for a week now. Do I need to reset the server names suddenly.

My “Sent” folder is now under my “Local” folder. How can I move it back under “Gmail”? Also, my “Sent” folder only contains 5 sent messages when my Gmail Account lists over 100 sent emails. How can I correct this?

I use Thunderbird on my desktop and since early June, I have not been able to receive any new messages but I can still send. Everything works fine on webmail (Yahoo) and phone (Samsung Galaxy), it's just my desktop which is affected . I asked Duck AI about this and this is what I got...

I tried the solutions offered without success.

I have a friend who send me things that I often like to share with others who are on a distribution list. He is also a member of that group. When I forward what he sent me to the group, I would like to exclude him from receiving that mail. How can I do this without removing him from the group list each time?

family and friends, communities sending info directions to my Inbox and I'm not receiving these emails. We always compare if I gave them the right email address. I need help to correct the problem.
