Stipefoarum foar Thunderbird

Since Thunderbird updated to 115.11.1 (64-bit), , the DEL key no longer deletes messages from within the message window. It DOES still delete the messages from within the message list. Any ideas as to why?

I set up a new Windows 11 PC (64-bit) about 2 months ago, and installed Thunderbird Supernova. I allowed MTS to choose all the settings and everything was working fine until about 3 weeks ago I am now running version 115.11.1 (64-bit). I noticed that many messages I recieve at scheduled times every day were not appearing in my MTS message list until sevveral hours (a few actually took 3 days) after their normal delivery times. Checking with the senders revealed no change to the time they were sent. Looking at the messages when they appeared showed that they WERE received on time. Logging into the web interfaces for Gmail and Comcast/XFINITY email revealed that the messages were arriving on time. The only logical conclusion is that MTS has a problem in its IMAP protocol implementation that does not recognize new/unread messages as such, and therefore does not retrieve them. I am legally blind, and up to this point, mTS is the only fully accessible, easy-to-keyboard-navigate email program.

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

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.

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!

Witam, w ostatnim czasie mieliśmy jakiś spam na naszą pocztę i dostaliśmy blokadę, zależy nam na zdjęciu jej ponieważ jest to e-mail firmowy i jest nam potrzebny. Proszę o informację co mamy zrobić aby zdjęto blokadę. Pozdrawiam

In Thunderbird, the content of all my Sent emails has disappeared. When I went to my Sent folder, the sent emails were listed but when I clicked on any of the listed emails, the body was blank. I right-clicked the Sent folder, selected Properties and then clicked Repair Folder. My Sent folder now lists messages that I sent today and yesterday and I can see the content of those emails... but none of the previous Sent emails are listed.

My email history is essential to my business. Unfortunately, I never figured out how to back up the Thunderbird file incrementally so I don't have a backup. Is there any way that I can recover my Thunderbird Sent emails?

P.S. If my Thunderbird Sent email history is unrecoverable, then I think I need to find a different email client that I can back up incrementally... or should I switch to directly using Outlook online in my Microsoft 365?

Hello everyone. I have just installed version 115.11.1 (64 bits) on my PC. The fonts of the incoming mail messages display strangely and change when I move the mouse over them. Attached are two screenshots of the same messages at two different times: https://mega.nz/file/vZtlBCSa#Hi_C1bjz4NNvG5WPfqSam1eefv7BHvF4bGv6VWNDZ8g

The rest of the programs and windows display normally. The problem only exists in Thunderbird windows. Does anyone have any idea what the problem is? Could a graphics card at the end of its life be at the root of the problem? Thanks.

I sent a message a while back about slowness with 115, which I had to download because I had a crash.

There were various suggestions, but no solutions to the excessive slowness with 115. This culminated to day in a long 'no reply' mail which suggested the issue might be the virus checker.....

I checked again the various messages about 115 - most were archived, only one month since they were posted!!

Is there an issue with 115?? I saw a thread which asked was I having issues with it, my answer is yes, is there nobody out there with a suggestion??

Witam, Mam problem z wysyłaniem wiadomości przez Thunderbird. Przy próbie wysłania wyskakuje takowy komunikat. Nie rozumiem z jakiego powodu mogłem dostać blokadę, ponieważ nie wysyłam aż tylu wiadomości, żeby można je było uznać za spam. Co mogę zrobić w takiej sytuacji, aby jak najszybciej odblokować swoje konto? Proszę o jak najszybszą pomoc, możliwość wysyłania wiadomości jest mi bardzo potrzebna. Pozdrawiam.

It has been one year, and you still have not fixed the multiselect functionality that was ruined with your Supernova "update" (which is worse in almost all aspects btw). Can you at least tell us WHEN you plan to release the fix since you locked the comments to block the countless negative ones? Is it so hard for your UX team to understand that removing multiselect functionality is like removing Ctrl+C, and Ctrl+V and set the correct priority???

I've just started getting error messages that I need to enter my password to send emails. I've tried that but it still keeps saying unable to connect to the server. This has been happening for about two days now. I've tried updating Thunderbird, restarting Thunderbird and restarting my PC. None of this has worked. I made no changes to my system, software or home network. Any help would be appreciated. Thanks, Dave

I have been trying to send a couple of emails today and I keep getting a server error message. I am not good at all with computers . I am a 78 year old partially disabled vet with no computer knowledge. My son set this up for me years ago but he has since moved away. I sent one email this morning that went out but now nothing works. I think I can receive emails but not sure now.

I see that others have had the same problem as me. My trash folder has many thousands of duplicate emails. If I block delete them it will take days to complete. So 3 questions 1. How do I stop duplicate emails in my trash. After deleting many reappear with the date 01/01/1970 2. Is there a faster way of deleting. I use select email>shift key>find last email>delete 3. Is there a limit to how many emails I can put into the block mentioned in #2

Dear community,

I use a MacBook Air (software version 13.6.1 (22G313)) and Thunderbird as my mail client (software version 115.11.1 (64-bit)).

I have set up approx. 8 mail accounts, but for a few weeks now I have had the problem with my google mail accounts that mail with somewhat larger attachments (approx. 5MB) is often (not always) sent, but no copy is saved in the Sent folder.

I get the following error message from Thunderbird:

The message was sent, but no copy was saved in the Sent folder because there were problems accessing the network or files (translated from German, original English error message may differ slightly)

Security and authentication settings of the affected IMAP and SMTP accounts:

SSL/TLS OAuth2

Changing these settings was not successful, sending mail was no longer possible with other security settings.

A request to google support did not help, I was referred to Thunderbird support.

Perhaps someone has an idea for me as to what the problem could be?

Thanks a lot and a nice day to you all! Hendrik

I suffered a BSOD on my fully up to date Win10 Pro (v 22H2, build 19045.4474)

Upon rebooting, Thunderbird is failing to open. The error message is:

   Unable to open the folder Inbox on xxx@example.com because it is in use by some other operation. Please wait for that operation to finish and then select the folder again.

There is no other process using the Inbox folder. I have rebooted and the error message persists. It looks to me like the more correct message would be that the Inbox or the profile is corrupted.

I see other threads asking how to restore a corrupted profile, but none of the answers are very useful. They all see to be tips on how to restore a backup of the profile at %APPDATA%\Thunderbird\Profiles.

If I had a backup of that folder, I wouldn't need to ask how to recover a Profile after a crash.

If it helps at all, when I opened the Error Console in Thunderbird, I see the following messages:

``` Uncaught Error: Component returned failure code: 0x8055000a [nsIMsgFolder.updateFolder]

There must be some tool that validates the Profile independently of Thunderbird.

For many years, my wife and I have each used Thunderbird on our own computers. Several weeks ago, when my wife turned Thunderbird on, a new screen appeared that mentioned account setup and directed her to set up her existing email address. When she did, a home screen appeared that was significantly different than the one she had been using. But more than that, she lost all her saved emails and Thunderbird started to reload emails. The reloading ended with over 1800 “new” emails whose dates reached back for almost a year. Since then, after some work, the home page has been returned to its earlier look; downloading, sending and deleting are working as before. Missing are a few important, personal subfolders. We’ve tried a few things that we thought/hoped would return us to the point before everything went crazy. That hasn’t happened. Recently, we looked at the Profiles folder on each of our computers and saw something that, I think, is unusual and, I hope, might provide a way get her back at least some of what was lost.

The route to my Profiles is C: > Users > Me > AppData > Roaming > Thunderbird > Profiles In Profiles are two folders, one ends with .default and the other with .default-release. The only thing in the default folder is the file times.json. The default-release folder contains many files and folders, including the Mail folder. The Mail folder contains two subfolders: Local Folders and mail.comcast.net.

On my wife’s computer, there is only one folder inside Profiles. The name ends in .default. Inside that folder is the Mail folder. Within the Mail folder are six subfolders: Local Folders, Local Folders-1, Local Folders-2, mail.comcast.net, mail.comcast.net-1, mail.comcast.net-2. The Date Modified date for Local Folders is probably the date the problem started. Date Modified for Local Folders-1, mail.comcast.net and mail.comcast.net-1 is the same: a few days after the date for Local Folders. The dates for Date Modified for Local Folders-2 and mail.comcast.net-2 are the same, and change daily.

I’m hoping/assuming that the missing, personal subfolders are in one, or more, of Local Folders, Local Folders-1, mail.comcast.net, mail.comcast.net-1. What I’m asking here is: does anyone know of a way to easily locate and recover the subfolders and, then, move them into the correct location in Local Folders-2and/or mail.comcast.net-2.

Thanks for taking the time to read this long story.

I have several Comcast.net accounts that I have set up in Thunderbird. About 2-3 times per week, Thunderbird makes me re-enter one or more of my passwords, only for the comcast accounts. It says Authentication Failure, but I have not changed anything on the accounts, including passwords. Entering the same password works - for a while. Any idea how to stop this?
