Thunderbird Community Forum

This month I downloaded the current version of Tbird on a new computer running windows 11. Tbird receives all my email but can not send mail. I have an old computer running on windows 7 which has Tbird that was loaded at least 5 years ago. It receives and sends email without problems. The two versions of Tbird are using the same SMTP settings: server: mail.twc.com Port: 587. My email account for Tbird is slengyel@triad.rr.com

I also have a gmail account which receives and sends on both computers without problems. My gmail account is steve.lengyel9@gmail.com.

Both computers run through the same internet network.

Messages that I have moved to Archive have totally vanished. A message which I needed to keep I found in 'deleted'. I then moved it to Archive - and it vanished altogether. I do not feel in control of this new Thunderbird! Please, is there any way of getting this message back?

TBird Version: 140.7.1esr

Since yesterday I can no longer click through with hyperlinks inside an email message.

I don't understand this.

I have already tried all the troubleshooting items to no avail.

To my mind, a change was made to TBird's functionality and this is stopping the click-through to the default browser and the opening of the page linked.

good day

we are struggling for the past two days to send emails . constantly getting the same error

Sending message failed

Failed to send message.

The message could not be sent because the connection to the SMTP server smtp.golf-south-africa.com has exceeded its expiration timeout. Try again.

PLEASE urgently help me. Thank you

I have removed an iCloud account from Thunderbird but it keeps asking for the password, I have tried removing all references to the account that I can find including the calendar. Any ideas? Thanks

I use the Thunderbird calendar in version 147.0.1. The calendar syncs with CalDav and works great. Although when the reminder pop-up appears i am not able to snooze (postpone) an event or delete na event. Nothing happens and the reminder keeps popping up every 5 minutes (as in the settings) untill the event has passed. Even worse, when i enable show missed missed events, i cannot even delete the old events in the list.

I've been using Thunderbird for many years. My current version is 45.2.0. My computer runs Linux Kubuntu 15.10

So yes, it's ten years old and it's showing its age. I have a new box I built, and have Kubuntu 25.04 installed. It installed the then current version of TB. I have yet to set things up, but migrating is a priority now.

Some solutions say (on ubuntu/kubuntu) to just copy the directory "/home/username/.thunderbird/profile.default" from the old to the new box. I would likely do it by zip, rar or ssh transfer.

If I do that, when opening up TB on the new box, does the data get converted? and if so, is it automatic? It seems to me that after then years, the data format would have some changes.

I'd appreciate any insight on this. Thank you.

I have 2 parallel accounts with the same ISP. As of 2 days ago, whenever I try to send mail, I get this message: “Sending of the message failed. An error occurred while sending mail. The mail server responded: Command rejected. Please verify that your email address is correct in your account settings and try again.” I receive mail as normal. Using the other address with exactly the same settings allows me to send normally as I have for the past ten years! Nothing appears different anywhere in the settings. There were no upgrades that I am aware of. I have since found that I can send from my basic little "travel" computer without issue. Any ideas? BTW, using POP mail settings.

When downloading a ICS appointment file to thunderbird calendar it takes you through 3-4 step for one download. Is there a shorter way to download ICS files to thunderbird calendar?'

Continuation of my prior post: https://support.mozilla.org/en-US/questions/1516342

Thunderbird has a routine problem with being unable to log into various mail servers. I have four accounts and they all seem to share this problem.

Most recent update: I've tested this in Windows Safe Mode, and the problem has not appeared. Since I can't do any useful work in Safe Mode, it's hard to give it a thorough test, but so far so good. Also, I have removed AVG antivirus because it was redundant. I have seen no improvement since it was removed.

Can this problem be resolved?

Greetings: Running TBird desktop with email provider Fidei. The email portion works fine (can send & rcv emails)...but upon accessing any of the other features, like Calendars or Lists...the content appears for a moment, then the Login dialog pops & my content for that feature goes blank. I'm providing (what I believe are the correct credentials) but it appears not to accept them...popping again. Are there separate credentials I should be providing for the other features of TBird? It didn't used to behave this way. Thanks in advance for any feedback/guidance. Ed in Tampa

Using FireFox browser

If IMAP folders have been deleted from the server, my understanding of the expected result is that they would no longer be visible on the client. Instead they display in an italic font. Is there a way to make these ghost folders go away? I've tried Unsubscribe from Deleted Folders (Folders display but no tick box to unsubscribe) Deleting cache directories etc all to no avail.

Am I missing something here?

140.7.0esr (64-bit)

I have the thunderbird app on my Linux SSD I set up Thunderbird all went fine when I installed my outlook account, I also have windows 11 so I booted into windows installed Thunderbird there and when I add the same account that i used on the linux. For some reason it wont let me sign in it gives me an account credentails error then send me to microsoft to sign in another way, the recovery email address is not the same as the one I have signed into linux on. I checked the password and recovery email I created and Im able to sign in the password is fine and the recovery email is as well. The thunderbird I installed on windows the account I am trying to add the recovery email is someone elses account not mine for recovery and its saying the password is wrong. I have outlook on my windows desktop and can sign in to that account I even signed out and back in again perfect. I checked the recovery email and password on microsoft web site for outlook and my account credentails are fine. I cant figure this out. It works fine on linux and the shortcut I have on my windows for outlook. But wont allow me to set it up on Thunderbird I installed on my windows. Why is it that thunderbird worked fine setting up on linux with my account but not on windows... I did delete microsoft edge a week or so ago I was wondering if that could be why I dont know.

I'm having problems getting my signature to appear in Thunderbird as it does in my soon-to-be former email client. I've attached pics of the signature as it should appear and as it appears when imported to Thunderbird. I can edit the HTML code, but I'm not sure how to correct things like the image not importing when the link is correct and how to get rid of the dotted line border that shows up in Thunderbird when it does not appear in my current email client signature. I attempted to attach my HTML file, but cannot. I can post the code, if that would be beneficial. HELP!

When I try to send my email I keep getting on screen messages from my old BT account continually asking for new passwords which I keep cancelling but it repeats over and ove again. How can I stop this?
