Hello

I have a bizarre issue with attachments.

I open all attachments in their respective programs rather than preview within Thunderbird itself (I have also tried opening in preview but I get exactly the same problem).

When I receive an email with attachments, mainly Word, Excel or PDF docs, I click to open the attachment but nothing happens. If I save the attachments to my computer and try to open it says the attachment is empty or corrupt.

But, if I click to forward the email, I can then open the attachments as normal by clicking on them in the draft email and also then save them to the computer and they open as normal.

I am running the latest version - 115.10.1 (64-bit) and I have noticed this issue for about the last week or so. Otherwise everything seems to work as normal.

Any ideas on what is going on or ways to change this.

Thanks in advance

For months I was experiencing the problem of "Thunderbird not responding" occasionally. It was a short duration issue (a few seconds to a minute). I reinstalled Thunderbird several times without success. I read almost every comment available online about this problem and I tried many ideas and recommendations I found without success. Most recently the problem became so serious that it was not a nuisance any longer. It was nearly impossble to work waiting for minutes to open an email or to continue typing while preparing a message and being interrupted by the problem I am describing. I ran Thunderbird in safe mode and determined that none of the add-ons is causing the problem. I turned the firewall OFF and determined that firewall was not causing the problem. I then decided to run Thunderbird in Offline mode and found that the program works normally. Then while in Offline mode I decided to download more messages and the program asked me if I wanted to switch to the Online mode. I said yes. New emails were downloaded and without going back to the Offline mode I was able to work normally without any occurrence of the "Thunderbird not responding" problem. I have been using this workaround for several days now. I download a number of eamails. I try working in Online mode and I cannot do it. I switch to Offline and work fine. I switch back to Online mode and I don't see the problem any longer for the whole day. Do you have any idea as to the origin of my proble? I am running Thunderbird 115.10.2 64 bit on Windows 11. I had the problem originally using Lenovo T490s and more recenlt Lenovo X1 Yoga

I belong to a number of newsgroups where I save technical data from that is in the form of email. 1. How can I save messages, with header intact, to a text file as I could with Eudora? 2. When I start Thunderbird, what email is loaded into memory?

The inbox had about 18 months worth of emails. I deleted three emails that had been flagged by Thunderbird as spam. Then I went to the trash folder and permanently deleted the trash that included many other unwanted emails.

When I returned to the inbox, the full list of emails was present but after clicking on any email there was no email content shown. A new email came in and the content was shown for that email.

The sent folder still shows all the sent emails.

After looking for solutions on the web, I selected the inbox, right clicked and opened properties. I then selected "Repair Folder". Now, the only email shown in the list is the new email that came in after the issues started.

I have looked for crash reports and it says there are no crash reports.

Suggestions....? Thank you, Peter

Hi! I have trouble setting the date format in the emails list. It should be the UK format as per the setting selection, however it is showing the American format. I am using Linux Mint and timedatectl says Time zone: Europe/London (BST, +0100)

I have attached screenshots. Please let me know what am I missing. Thank you.

I have read the instructions offered in the FAQ's but is not clear to me. when I type in my filter name and then select "+" after the email addy I get error about filter name already exists...

Hi. My hard drive crashed. I have a new pc and the old drive is readable in a drive enclosure hooked up to new PC via usb. I have done the typical search for the appdata profile file, but I am not sure what I have here. I have attached a screenshot of the old drive and a global search on "Thunderbird". I am not sure where the profile file is residing. Any advice would be welcome. Thanks.

My e-mail inbox shows a high gigabyte use-age rate, but I only have a few messages in there. I get my messages a couple of times per day and delete emails I don't want to keep. Now it will not get all my new messages as it saying I have run out of disk space. It seems that messages I delete don't really get deleted?? even though they go to trash and I clean the trash folder. I have tried compacting but that didn't work. It seems to be only on my win 10 laptop, as my XP computer is working fine. I have plenty of disk space left on the hard drive. Thanks in advance Bob Parkman

I've been noticing apparent duplicate messages within my unified folders inbox on my desktop recently.

Looking further I notice that one of my accounts has 'INBOX' as one of its subfolders which is where the problem appears to stem from. When I look at that account in isolation (ie not in unified folders) I can still see the inbox as a subfolder.

The subfolder 'INBOX' appears to be a duplicate of the account's main inbox (it contains the same number of emails), which may account for the appearance of duplicates.

At a guess this is probably related to inadvertent moving of folders. I find that when trying to use the scroll bar (to scroll down the subfolder list), if the mouse strays slightly to the left it will pick up a subfolder and move it unintentionally. This can cause all sorts of problems with disappearing emails and the folder structures showing differently on different computers.

In this case the duplicate email problem only happens on my desktop. On my laptop I can still see a subfolder named 'INBOX' but it shows as empty and I don't see the duplicate emails in unified folders.

It would be really useful if Mozilla could introduce a 'confirm folder move' feature as that would eradicate inadvertent moves.

How do I resolve the apparent duplicate emails on my desktop? I am somewhat reticent to delete the subfolder 'INBOX' for fear of the potential consequences. . .

Good morning, This morning thunderbird was not responding and allowing new emails to come thro. So i repaired the folder and now it doesn't display the messages in my inbox. Could someone help me with that? If you want to message me privately thats fine too daryl@doubledtrailerparts.com

Checked everything. Not sending after upgrade. Is sending in troubleshooting mode.

No add-ons.

Not anti-Virus or firewall issue because I shut them down. to test. With both on it sends in troubleshooting mode.

I have spent many hours combing thru possible solutions.

Please help. TIA.

Im using Thunderbird Beta release. Starting last week, my PC would become extremely slow, to the point it would nearly come to a complete halt. After digging around, I realized it was due to excessively large Thunderbird NSTMP files that were being created. I would delete them and the speed would improve. But then a while later, the NSTMP files reappear and gobble up all my Harddisk again. Part of the issue is the sheer large size of the file, which will consume all available space on my HD, which at present is 600GB. But it also eats up all my RAM so my system slows down til the NSTMP file is fully built.

I use this as imap with Gmail installed on a PC with a 1TB SSD

Today after my pc started slowing again, I started poking around and noticed my main Inbox is massive, 29GB, which there is no chance its that large. All Mail is only 1GB to give perspective

This has been going on about a week.

I tried repairing my inboxes and other folders, but that does not seem to have helped.

I am running Thunderbird on Linux Fedora. I have two accounts set up. One of them is an icloud account. Every day, many times per day, it prompts for password. I have a nightmare to get one for it due to the new way Apple deals with stuff like this. I have to get an 'App Specific Password', which involves logging in, which I hate doing and doesn't work because I use a VPN and Apple discriminates against VPN users and locks my account every time i login (even though it's the same IP address every time).

I did manage to generate one, which got rid of the problem for a day or two, then it came back, generated again, and so I go around, each time having to unlock icloud account, remove old password, generate a new one, paste it into TB and then its fine for a few hours/days.

Would be very grateful for any ideas why this is happening and how to cure it.

thanks

I'm setting up Thunderbird for the 1st time with multiple email and calendar accounts.

One of the accounts, an O365 account, is not setting-up the sub-folders.

I was also having issues with the same account's calendar and have implemented Tbsync Account Manager from the add-in and that seems to have fixed it.

Now on to the folders issue. The only folders appearing are the Inbox and Trash.

Any suggestions?

Has anyone found a way to have a separate "reply signature?"

The use-case is that I may send an initial email with a 'complete' signature (first name, lastname, email, phone, etc.). But when the other party replies it would be nice to then reply to that with just my first name. Or at worst, auto-insert the full signature.

I've setup my full signature and auto-populates when I create a new message. But not on the reply.

Any suggestions?

Hi,

I have just setup a new Office 365 account in Thunderbird and when I try to send an Email from the account, I get the attached error message.

When I click on "Enter New Password", the window goes away for a moment and then pops up again. There is no chance for me to put in a new password.

I know that I need to use an app password when not using Outlook which I have generated in my Microsoft account settings.

I have tried to go to "Settings -> Privacy & Security -> Saved Passwords" and have deleted all Microsoft related saved passwords. When I access my Email account again, I get prompted via the web login of Microsoft (i.e. different from the attached error message) and the app password I generated doesn't work, only the general password for my account works.

I have restarted Thunderbird and updated to the latest version, but it made no difference. I have gotten it to work on another computer, but on my mac mini, it doesn't seem to work.

Before I remove the account completely and add it again, is there any way I can fix this as I don't want to download all the messages again?

Is this a known bug in Thunderbird?

If any developer is reading this, In order to reproduce, you would have to follow these steps:

- Setup a Office365 account using the regular password used to login to the O365 website. - When sending the first email, enter the same regular password -> the first time, the dialog to enter the will show up, but it will fail, because the app password wasn't used - Then try to send again, click on "Enter new password" -> no dialog to enter new password is coming up.

I am using Thunderbird 115.10.1 on MacOSX Sonoma 14.1.1

The settings I have used are: server name: outlook.office365.com port: 587 username: my full email address Auth Method: OAuth2 Security: STARTTLS

Thank you for reading this. Looking forward to a reply.

Hello,

i have a mailserver with a catch all function and give out only customized mail adresses. Think "paypal@domain.com".

That way i know exactly who "lost" my mail address to a spammer.

However when i want to reply, the sending mail address defaults to the one i am logged into.

Is there any possibility to configure Thunderbird, that the sending mail for the reply is equal to the receiving one i am replying to?

My existing email provider (iiNet) here in Australia is no longer offering an email service. I have been recommended (by iiNet) to transfer to a company called 'The Messaging Company'. Already I have had an issue with the Messaging Company on account of their poor customer service. I note that Thunderbird has a Global Inbox. Does this mean that you are able to offer me an email service that will allow me to keep my current email address?: brucepitt@iinet.net.au If you are able to help, an estimate of the cost for this service would be appreciated. Thanks in anticipation, Bruce Pitt Queensland Australia
