Thunderbird Community Forum

I've used Tbird for PC for years with no problem. A month back, I installed it on my Android, then used the desktop "Export for Mobile" option to recreate all my emails (I have several) on my phone. The setup worked and I receive emails. But realized last week that no one receives emails I send from my phone from my domain emails.

No error messages, no bounces, and email ends up in Sent folder. Plus, bcc'ing myself, I receive them. I double-checked outgoing servers. These match what is on the desktop Tbird.

However, emailing from my gmail account in Tbird on Android works--email received. Just the emails from my domain don't go through.

versions: TB for Android 10.1, Verizon (samsung) android (v 15) set to cellular (vs wifi) for internet, I have emails via my domain on shared hosting service.

Thank you!

Hello,

We are using Mozilla Thunderbird on a Windows-based computer to manage our corporate email hosted on the Yandex domain. We are facing an issue: emails sent to addresses ending with @gmail.com do not reach the recipients. However, we can successfully receive emails from @gmail.com addresses.

Could you please advise how we can resolve this issue and what settings in Thunderbird should be checked to ensure correct email delivery?

Thank you!

To whom it may concern

All of a sudden Thunderbird desktop Version 142.0 is constantly running Building summary for inbox, not sure why the steps i have tasken to try and resolce this issue are delete inbox.msf and global-messages-db.sqlite files

Unfortunately, thunderbird freezes and is nonresponsive or crashes when trying to build the summary file for my inbox

Please help me figure out how to get thunderbird working properly again

Thank you

For months now, when deleting emails in Thunderbird, it sometimes creates multiple records of the same deleted email in the Deleted Messages folder, sometimes several hundred copies of the same email. It doesn't do it for all deleted emails, and I have not been able to discern any pattern or cause. As a result, my wife's Deleted Messages folder has 8,700 deleted emails in the last 3 months, far more emails than she receives. Edwin Miller

Hello,

I recently "cleaned up" my inbox for an email account that is many years old. I did this because old emails that come up in search are found, but blank. So per Mozilla recommendation I "cleaned up" this folder but when it finished it removed every single email except for one from 2011 and starting in mid 2024. Everything in between is either hidden or gone.

What happened and how do I get these back? They weren't deleted as they aren't in the trash.

Thanks!

I have tried at least 6 different ways to get my unique 'local folders' copied into my new computer running windows 11 from old windows 10 computer. I've tried different ways of copying folders, copying in the unique ini address, using the "%AppData%" approach and several other ways I've found on internet searches. None of these are working. Could several people tell me how they recommend I do this so I can find if there's another way I haven't tried yet. Very frustrated with this and wish I hadn't bothered donating to Thunderbird ever since this problem has cost me at least 15 hrs of my life at this point. Transferring filed emails that took years to fill should not be so cumbersome and should be a much easier task. Shameful. Thanx.

Recently I've noticed that Thunderbird asks to compact folders very frequently and if I say 'later' the size of the file needing compacting grows substantially each time (typ. 3 to 5 GB increase). See attached screenshot When I finally tell it to compact folders, the message pane goes blank but usually (but not always) returns. When it does come back there is an error window (See attached screenshot )

This is a new phenomenon and is making Thunderbird a pain to use: it wastes time and is scary when the Mozilla support pages say it can lose messages. I'm reluctant to have it do compacting automatically.

Can this bug be fixed? I'm on 138.0.1 on Win 11, but the question in support only customizes to 128. Probably irrelevant. I have plenty of disk space and RAM space available

I'm a decades long Eudora/Thunderbird user and don't want to have to change to something else. Thunderbird is great, except for this.

Help please. Thanks,

I've been using the current version of Thunderbird Daily for several months without any issues. I recently started using the Calendar and assigning specific categories for events. I'm able to easily assign different colors for each category, but unfortunately the color displayed on my calendar is always the same (sort of a pale red).

Hoping someone can help me figure out why my events aren't being displayed in the appropriate color of the assigned category.

Thanks!

PS. The ScreenShot shows several events that have been assigned different category colors

I get the following message from Thunderbird and denying to send it: "Sending of the message failed. An error occurred while sending mail. The mail server responded: [VO-101] Message blocked due to spam content in the message.. Please check the message and try again." I spent quite a bit of time with my ISP and the tech did a number of tests and then determined that it is a Thunderbird problem. She then had me go into Thunderbird outbound settings and check "Normal Password" once or twice and the problem was solved for about 2-3 weeks...until today. The system is back at it's old tricks and now I can't even send out a message with a simple link to a story, article, etc. Not always, but if I try to send it to 10-20 friends, it kicks the message back with the above message. Needs a permanent solution. Thanks.

I right clicked on the trash and hit empty trash which then not only deleted my emails in my trash but also deleted my sent & inbox emails. Why did this happen and how do i get those emails back?

Has anyone out there received a message or messages 4-6 weeks after the send date. In cleaning my files I often find unread messages from months ago even after I know I have deleted all messages from a specific source. i.e, a friend of mine sent me an email then was a little bit discouraged when I didn't respond. I went back at looked at my messages and his was nowhere to be found. About 3 weeks later when cleaning out my messages, there if was, unopened and about 3 months late. Anyone else experiencing similar problems. This is not the only incident in which this has happened. the same has happened with other no so important messages.

Recently my Intel NUC died and I have switched to using n ASUS Strix laptop with a Synology NAS storage. Since that switch whenever I start up Thunderbird I receive this error message; " The folder ‘Inbox on meddingsbasil@gmail.com’ could not be compacted because writing to folder failed. Verify that you have enough disk space, and that you have write privileges to the file system, then try again."

I am not sure if the error is in my ASUS Strix or in Thunderbird or elsewhere. If you can help, please note that I am a senile old geezer of 95 years and 7 months. I used to be OK with computers but I am now getting forgetful of how to do things.

Can you help ??

For the past 2-3 months my thunderbird has been virtually unusable. I can not pin down the issue but I reboot and restart the program and sometimes it works for seconds, other times it works for minutes or even hours. But I can not get through an entire day without it crashing. I need help with this issue. I am running Windows 7 Pro which is likely part of the problem. But this release states that it still supports it. Is there a solution to this problem?

My tags stopped working, right click -> Tag no longer has the list of tags, although 'Manage Tags' shows my list of tags and 'New Tag' applies the tag to the selected message, but no tags appear on right click-> Tag list. I'm using Mac OS Version 15.5 and Thunderbird 139.0.2 and have rebooted and reinstalled Thunderbird to no effect. Thanks for any help you may have!

Several times a day, TB pops up a message box with the following...

The folder 'Inbox on email@domain.com could not be compacted because writing to folder failed. Verify that you have enough disk space, and that you have write privileges to the file system, then try again.

I have a few accounts in TB, and it does this for all of them, but at seemingly random times.

Everything seems to work, it's just annoying to have these messages pop up.

I have 0.9Tb free space on the disk, so I don't think it's a lack of space! I also have admin rights to the file system, so that's not it either.

Anyone any idea why I get this? Thanks

Hello,

I run TB 141.0-64 with Windows 11 and am on the Release Update Channel. I've had Spam sorting problems for about a year, through many TB updates, and many Windows updates.... I run SFC, and DISM, regularly.

The Spam difficulties are of two types: Many messages appear in my Inbox, are marked as Spam, but are not moved to my Junk folder, so, I move these to their Junk home manually. Also, many messages appear in my Inbox that are obviously Spam, but are not marked as such, and, of course are not moved to my Junk folder. For each of these, I click on my Junk button, and these messages jump over to their Junk home to meet their new friends. Often, messages of this second category, are identical to messages that have been properly moved to my Junk folder earlier.

(Though possibly unrelated, I'll also mention that my CTRL-K Search function has failed for many months, typically, unable to locate messages that I then can locate manually.)

Finally - The the Spam sorting problems I've described, are intermittent. I can sometimes go for many hours with my Spam tools working as they should. Then, the Spam sorting system fails again, as I have described.

I express my thanks, in advance, for any assistance that you kind folks might be able to offer,

Lothar

I need to migrate from Outlook 2010 to Thunderbird latest version. There are multiple email accounts configured in Outlook and tons emails. This is my wife's system so I don't want to make a mistake doing the conversion.

I intend to use a automated tool if a reliable on exists - paid is fine. I need to get all of the accounts and associated outlook folders moved to tbird. Also need contacts migrated. Some of the Outlook accounts use POP3/SMTP, some use IMAP.

What is/are the best migration tools? Recommendations welcome. What traps do I need to avoid? What is the recovery process if it all goes wrong.

I have 50+ years IT experience and have used tbird for 10 years so I'm not clueless.

Thanks in advance.

Good morning.

Problem 1. I've been using Thunderbird for a very long time. Everything has always been fine. But recently, I've been having trouble sending email from one of my accounts. When I try to send a message, a message appears: enter the password for the user... Entering the password doesn't help, and another message appears asking me to contact the network administrator. I contacted them, but they didn't find the cause of the problem, but they suggested changing the password, which I did, and reinstalling Thunderbird, which I didn't do for fear of losing all my email. Changing the password helped for maybe two weeks, and then the problem started all over again. The problem only affects one email address and only on one computer. Sending messages from that address on Android works without any problems.

Problem 2. I installed Thunderbird on my Android phone and encountered a problem when adding two accounts: the first installed without a problem, but I can't install the second one because every time I try, I get a message that the incoming mail server check failed - unknown error 42.

Problem 3. I'm trying to install the program on my second phone - it downloads 99% from the Google Play Store and that's it.

Is there any way to solve these problems, or should I change my email program? Best regards, Andrzej Witkowski
