Forum Dukungan Thunderbird

A bit of an odd request, I know, but I'm trying to send encrypted email from Thunderbird such that only the recipient, and not the sender (me) can access the message once it has been sent. I direct Thunderbird not to save a copy in the "Sent" folder when I do this, but Thunderbird still encrypts the message such that my personal key can decrypt it. Is it possible to send a message that can only be decrypted with one key? I have access to the recipient's private key, if that helps.

Thunderbird has suddenly stopped pulling in email, please help. It just says 'Checking mail server capabilities'. I have changed no settings at all. Webmail works. Email on my phone works. So it's not the ISP or the server or anything like that. It's just on Thunderbird where I can't do anything, but I've not changed anything so I don't understand.

When I try to send email it fails and says: Sending of the message failed. Unable to communicate securely with peer: requested domain name does not match the server’s certificate. The configuration related to mail.mandyhaggith.net must be corrected.

So please can you tell me how to correct the configuration?

Thank you for any help you can offer.

Best wishes Mandy

Very soon after startup it begins to stutter with the spinning beachball of unresponsiveness. At first it will spin, then come back for a few seconds, then spin again. Eventually the whole app is unresponsive.

The troubleshooting steps I see on here all start with "Go to [some location in the menu]". I can't do anything with anything in Thunderbird. I can force it to quit and start it up again, that's about it.

It is also always asking me for the passwords of some of my IMAP accounts. These are big accounts, some folders have several hundred thousand emails. The Inboxes are smaller, maybe a couple hundred in total at the moment. The last configuration I was able to make put it into Unified mode.

The damn thing is that after having been useless like this ever since I installed it, last week it started to work fine. Stayed that way for several days. Eventually that failed, though, and my whole Mac ended up locked up the way the app is, I had to manually power it off.

I don't know if it writes any info about what it's doing to a log file somewhere, I am not having much luck trying to find any information here. Just other people with similar problems but no substantive replies.

Using Thunderbird on an older Mac laptop, running macOS Monterey 12.7.5.

I was setting up my new email account on thunderbird and I was facing some issue, so to solve the issue I set up the account without entering the password, but later when TB is asking for the password and I am entering the password then TB is not accepting it, it is only showing that "Login to server imap.gmail.com with username 23je0520@iitism.ac.in failed".

please fix this problem.

Hi,

I am running Thunderbird 115.10.1 (Flatpak) on Ubuntu 20.04. (no extensions except birdtray) I have 4 email addresses added to my TB, and I like to see all of them together, therefore I am using Unified Folders. When I am accessing Unified Inbox, TB is very slow and basically frozen until it loads this folder (often a pop-up appears that 'TB is not responding'). it takes between 30-60 seconds to load my emails (either on start-up, or clicking on another folder, then going back to Unified Inbox). Every other folders open almost instantly. I have to admit I have a lot of emails in the Unified Inbox (~20K), however the inbox of my main email has 18K, and accessing that folder separately is instant. So any operation, other than opening Unified Inbox, is quite snappy.

This issue persists since I upgraded to v115, even when I did an OS reinstall (also tried installing apt (v115.11.0)).

I have seen this answer: https://support.mozilla.org/en-US/questions/1428374#question-reply however, nothing changed by resetting the folder.

On startup TB pops an error box up saying ' There is no email program associated to perform this action'. When dismissed TB continues to open normally. No other errors seen during operation.

I have checked my Win 10 Control Panel Apps options. TB is the email default. MailTo, file type .eml and all other settings I can see are set to TB as well.

I have tried nearly everything on all the forums and help sites to no avail. I still get the error message that my message cannot be sent. Most of the time I get the server response as [C20]: message blocked. I have triple-checked my SMTP server settings and password, uninstalled TB and re-installed. TB seems to have recently changed the profile in use, so it no longer has all the files in Mail\Local Folders it used to have. I'm thinking I need to create a new profile but I don't know how to do that.

I have two identical instances of the Thunderbird 115.11.0 (64-bit) installed on Fedora 40 (two different boxes) They display Email preview differently (See attached pictures)

Anybody knows how to change that view? What settings?

I am writing to let the community know that, at least in my case, the guidance from TB 1/2024 KB article on Qauth2, [and linked Microsoft article], didn't solve the odd password behavior that began around January, 2024, between TB and my Microsoft hotmail account--which had worked perfectly with TB for maybe 10 years?

Beginning in January I typically received an error message that SMTP server login failed; please enter password. But after fixing that as per the KB article (first trying to maintain normal password, then when that wouldn't solve it, turning on 2FA, switching to Qauth2 with cookies enabled), it turned out for me that with Qauth2 and 2FA, I could send mail okay but then the Outlook.IMAP server would not connect so receiving emails stopped. Several times after this failure I tried switching back to normal password AND turn OFF 2fa in order to get Outlook.IMAP to reeive email...but then SMTP would keep requesting passwords, and every day or two i'd get a repeated request to reenter the Imap server password for receivfing also.

The only stable fix I found after weeks of livign with this and debating abandonment of TB came when I turned 2FA back on, requested an app password from my Microsoft Account, changed TB Server settings back to Normal password for SMTP and Outlook.Imap, and then entered the App password when prompted by TB for to eonnect with server for receiving and sending.

This has worked fine and apparently been stable, without new reqauests to me for passwords, for 2 days, whereas all other fixes in past couple months have not lasted longer than a day or less before TB requests again that I enter a password to connect with my hotmail account. (All through this my gmail connection via TB ahas remained flawless, thought I did get a request for a gmail app password, which I obtained and entered--just once and all has since been fine).

I don't know why several careful step by step attempts to do everything in Mozilla's Thunderbird KB and Microsoft articles suggested didn't work--for a residential Microsoft account, whether I tried to follow guideance for those experiencing SMTP problem only, or the Imap server connection generally.

My only guess about why my Win 10 desktop installation is different? I have Outlook for Android running on two or 3 different Android devices also, perhaps that complicated things?  I also used to have a mirrored account (in other words, name@hotmail.com is my main account, but I also had a 2nd "nickename" acct with the same name, set up as name@outlook. com.  

(But I removed that nicknamed acct in case it was causing any of my authentication problems; made no difference. )

I had a problem where emails from two months ago were empty meaning that when I click to open them, they contain nothing. I tried using the Repair Folder tool. Now, almost all of the emails in my inbox have been deleted. Unfortunately, I did not back up the folder. Any way to get these back? Is this expected action when using the Repair Folder tool?

Thank you

I installed the Thunderbird software on (2) devices to replace the Windows Mail product. On the first device (Windows 11 laptop) I was able to add all (3) personal email accounts needed (1 Spectrum and 2 Gmail). On the second computer (Windows 11 MS Surface) i was only able to install (1) Gmail account and the Spectrum account. The second Gmail account gives an error when it tries to verify the account with Google giving the error as follows.

400 that is an error. The server cannot process the request because it's malformed. It should not be retried. That's all we know.

Since the settings on both computers are the same for the account and both Gmail accounts work on one computer this doesn't make sense to me. Any suggestions would be helpful.

I can't send email from comcast.net account. Outgoing server (SMPT) ERROR. Comcast said problem with mozilla. What should password be for comcast smtp://smtp.comcast.net (smtp://smtp.comcast.net)?

I've been using Thunderbird for a very long time now but I've never experienced this kind of problem: I have few outlook.com accounts set up and looks like I can't send emails from outlook.com using Thunderbird. To send a new email or respond to my emails I have to manually log in to my outlook website account or use my phone (Android). Every time I try to send or respond to email the Thunderbird I get these messages (included in the attachments): no connection to the server or it keeps asking me to put my password even though passwords has not changed. There seem to be no problem with receiving emails.

Tired of Apple mail, want to install Thunderbird 78.14.0 on my mac mini. Am running Yosemite 10.10.5.

I can see access to the files on this site but need an installer to load to system.

Am familiar with unix can work off a console but am not a programmer, wouldn't know one end of a compiler from the other.

Can you point me in the right direction?

Hello,

My boss, (small family business) insists on using Thunderbird for the business. He sends and receives hundreds of emails every day. Often times has 20+ email tabs open at the same time. It's become such a problem that I have purchase larger SSD drive because he was always running out of storage space on his PC. His Thunderbird file is currently over 12 gig.

The main issue is: He will have several emails open and will start to reply to a customer. When he hits reply, the body of the email references data from an really OLD previous email that was either archived or deleted. Most of the time these are emails that were previously deleted. Then he goes back to his Inbox to try to find the original message and it cannot be found and is missing. He then finds the original email on his iPhone Inbox (Same Email Account - IMAPED to his phone) then forwards it to himself, in order to obtain the original contents of the message again. Sometimes the reply box has data from multiple old emails! It's hard to explain.

This goes on and on and he's driving me nuts, as I'm the local "Mr. IT Fix it." for the company. Although, I have no formal degree or training in such things. My background is in Accounting. LOL

From reading other forums, this appears to be either an IMAP Indexing or Email Deletion Retention policy issue? But it's just really beyond me!

Both myself and a family friend who actually has IT support exp. have told him to stop using Thunderbird for Enterprise use, and migrate to a more appropriate application. But he doesn't want to have to learn anything new or complicated.

Any thoughts, suggestions, other places where I can find a possible solution?

One other thought: This issue does goes go away (albeit Temporary) when I clear his system cache and Force ALL Thunderbird folders to Compact. Thank you!

If the above data is too vague, I can try to provide steps to replicate and screenshots on the next time this happens. Which is often. However, it is almost impossible to replicate on demand.

Additionally - I've read in other forums of similar issues where they were related to indexing and IMAP syncing across multiple devices. One person commented - that it was a deletion retention failure policy within Thunderbird. Something to the effect of, Thunderbird never really deletes emails when you press delete on the desktop application. The email is marked for deletion but all of the email headers and data is still stored in the active cache, or something like that. - And apparently, there is a lag in time that the server or servers update a deletion request if the email is deleted from another app. His primary email host is Comcast.net. So, he's using Comcast Webmail, Thunderbird Desktop, and iPhone 13 mail app. via IMAP, all for the same account that has about 10+gig of stored emails. Oh, he currently has threads turned off by request. Storage cache is currently set to 650mb.

Any help, suggestions or solutions are greatly appreciated. If you have any areas that need clarifying, I would be happy to take screen shots or provide additional data in order to find a valid resolution, as he's not interested in migrating to Outlook or any other Enterprise application.

Thank you!
