When opening an eml file saved on the desktop, only a white page appears.

I have the latest version of Thunderbird installed. The email opens without any problems in my inbox. When I export it as an eml and open it again in Thunderbird, a blank page appears. The size of the file seems to indicate that the content is still there. This error affects several Windows 10 computers on the customer network. I exclude the usual errors, such as assignment of the standard program and incompatibilities

I am grateful for any advice

I have an email account with multiple identities (aliases), some of which I would like to add under the same OpenPGP key that I'm using for the main identity. I couldn't find any option in the OpenPGP Key Manager in Thunderbird which would allow me to add identities to the key. How should I go about doing this?

Hello, I have for a long time a mail "stefan.ch@aliceadsl.fr". I recently changed computer and wanted to add it in Outlook 2016. Failed. I tried to do the same with Thunderbird, after reading that I can recover/integrate a ".pst" file with my historical data from Outlook 2007 (the previous one) Failed. Messages saying that "cannot fond the server". Stephane

in inbox suddenly some mails became empty and cannot be deleted nor moved nor archived, other messages not affected. It happened earlier and was asked to delete the inbox folder, that worked. But again same problem happening on the same email account, other accounts no problem. See screenshot, the bad ones have red star. Clicking on bad ones: empty screen.

Hello,

when i do copy and paste from documents, mails or websites i always do it via right-click and paste without format (idk the correct english term, cause i am using the german edition).

Often the text is displayed without format (thats what i want!) but when i send my mail its written in the copied Format (e.g. Times New Roman). Its a little bit confusing that there is text format, when i insert it. The opponent is getting my mail in wrong format. How can i change it? Am i using the paste wrong?

Context: I have set Thunderbird (version 128.13.0esr) to user Mail Dir. I am using a RHEL10 based distro (Almalinux10). Everything is working fine with received email. I need to manually process the received mail folder with an automation utility I had written in the past that was based on a Maildir folder structure.

I read through the article: https://support.mozilla.org/en-US/kb/maildir-thunderbird - and noticed that it was around 6 years old and could not find any updated articles re. the current status of Maildir and Thunderbird.

My question(s): I noticed that the Thunderbird Maildir structure under the email profile does not seem to have a folder named 'new', it only has 'cur' and 'tmp'. This does kind of make sense, as from what I understand, the 'new' folder is intended for messages that have been delivered, but not seen by any email applications. I am guessing Thunderbird has the email received in its user inbox, so it belongs in the 'cur' directory as it has been 'seen' by Thunderbird?

I was just wanting to confirm that it is that case that all email received by Thunderbird using a Maildir directory structure will always appear in the 'cur' folder. For reference, in my previous setup, fetchmail was retrieving email from a remote email server and as a result all email received appeared in the 'new' directory. My automation application processed all email in the the 'new' folder and archived them once processed.

Thank you.

Hello! I have used Thunderbird for many years. Lately, it waits much too long to prompt compacting all accounts. When "Compact all folders when it will save over ..." is set down to 1MB total, it still does not prompt until it has to clear 30 or 40 MB.

It didn't do this in the past, prompting me every 2 or 3 days at higher settings. So, I'm curious if this is "normal" now and I need to manually compact, or if there is a problem with 'Account Settings > Disk Space > Compact all folders' ... ?

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

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

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.
