Thunderbird Support Forum

Hi, I kept OS Snowleopard around for years too long in order to keep using Eudora. I finally got fed up with viruses/crashes, having to rebuild the mailboxes, but I was never able to find anything to take its place and have frankly been limping along ever since. I regularly need to find things going back months, years, and even decades. It used to be simple with Eudora. Recently, one of my parents passed away and I'm kind of the family scribe, so I really need to pull together all the past communications, from Eudora (going back to almost 1990), gmail, yahoo, my website, icloud, my college alumni address, my Ronin Institute address, my 15 Sonic addresses--and there's probably a few I'm forgetting offhand. I really need to consolidate them. I tried various email clients, including years ago a previous version of Thunderbird, but they were a lot of work to set up and couldn't handle all the email addresses.

I see better reviews of Thunderbird now. Can Thunderbird really handle all those email addresses? Since my Eudora mbox files are still on OS Snowleopard, and I'm running Macbook M1 with the latest OS now, what's the best way to incorporate the entire archive of messages and also start hopefully wrangling current messages (like I haven't been able to since I had to stop using Eudora)? Eudora pretty much only did POP well, and I actually did appreciate having my data on my own computer, but now there are some email accounts I'd prefer as IMAP and others as POP. Is it possible to mix them? Is it possible to download AND keeps messages available for viewing by phone? This situation has been a problem for me for years--I was just wondering if there might be any volunteers at Mozilla who might be willing to spend a few hours on the phone with me to help me bring my email into the 21st century? Nearly every day of my life I have to let someone down over something I can no longer do or find because I don't have Eudora. But the problem doesn't go away just because I find another program that does some of the things Eudora did--I really need some help integrating everything. Thanks so much for all you do!

Thunderbird, new installation, with 5 email accounts. Only one is of any size (7+ GB), but it is only sync'ing 6 months of messages, so the amount on disk is not huge. The 4 others are all below 1 gb. After just a week or 2, I am getting the "compact folders" alert, and it offers to recover 51.9 GB of disk space! This worries me, because I had just about 25 gb of disk space free when I installed Thunderbird, so it can't possibly recover that much space. The Thunderbird folder in AppData/Roaming is only 1.74 gigs. Where is it getting 50+gb from? I'm afraid to run this maintenance task.

for years I have used Thunderbird, and during that time have replaced serveral old pc/laptops. My new laptop when trying to open Thunderbird asks for a password. I have no record of that anywhere!! So how do i create a new password or gain acess to use Thunderbird. Im using Windows 11

When I use a html signature with graphics, the recipients who can not receive Html, do ot receive the grafics, obviously, but also not any other attachment like a PDF file. The same is sent but not received! in other words, our customer complain that we forgot the attachment, but we did not. If I resend without the signature, they receive the PDF file. If I reply with an attachment and have a previous signature with grafics in the feed, the attachement also disapears. The only solution is no grphics in the signature, but that is not a solution, just a quick fix. Thank you very much for your replies.

Get this error message when I try to send an email:

"Sending of the message failed. The message could not be sent because the connection to Outgoing server (SMTP) mail.twc.com timed out. Try again."

Spectrum blames Thunderbird. How can this be fixed??

After recent update, TB seems to have created an extra account. My account has name <myemajl> and ends in ".com". New acct has same name but ens in .com_2. That's why I think TB created it. Which do I delete and how

I have a few accounts that I access with Thunderbird. There are a few times where I go to compose a message to a professional contact, then Thunderbird sends from my personal address instead. This may be a default behavior, but it's almost always a face-palm moment.

I wonder if there may be some clever way to associate and address with a certain mailbox/account. So that if I send to that address, the collected history from Thunderbird would show that it was sent "from" one address and perhaps present that address as the default when composing a new message.

Or some other clever way?

Thanks.

When thunderbird successfully sends an email but seems unable to save the file to the email server it offers to save it locally for now. We have several of these locally saved emails and would like them to appear in the sent folder in our email client and on our email server. Please explain how to get these temporarily saved local emails to appear in the sent folder?

After years without problems, Thunderbird suddenly started locking up when I try to insert an image into a new message. There is no error alert; the message just completely locks so that I have to force task to end. Until a couple of weeks ago, I was able to insert files stored on my computer or copied from browser with no problem at all. [Not talking about a signature, just an image. Emojis work fine]

Am not aware of changing anything. Running Windows 11 Home version 23H2, if that helps anyone explain what's happening. Thunderbird version 115.5.0 (64-bit)

Haven't tried un/reinstalling TBird as want first to see if there's an easier solution (have several accounts).

I have just switched to Thunderbird from Gmail. Have tried several times to send bulk emails but always get this message:

Sending of the message failed. An error occurred while sending mail. The mail server responded: We have detected an unusual amount of suspicious mail originating from this address. Please try again later.. Please check the message and try again.

I have a need to send emails frequently to more than one address and this is going to be most inconvenient if it can't be fixed. Is there a setting somewhere?

Thank you.

Hello, I would like to set up root level folders for my alias addresses rather than having them in subfolders. I have tried setting up a dummy email account, but the filter won't transfer emails to it. Is it possible to do what I want?

There are times when I have 100's of messages in my INBOX, and others where for some reason, TB has my current message way below. So, on MacOS at least, I get the side bar active and I move it to the top. But I thought how clever it would be to have a button that simply reset the view to the top-most (current) message.

I have used Juno for one of my email accounts since it was first introduced in the 1990s. More recently, I have learned to use Juno's POP and SMTP servers, however in recent years some issue developed between Juno and Mozilla/Thunderbird, wherein TB will not place a message sent through Juno in the Sent or Drafts folder (as applicable) on the Juno server(s), forcing TB to use separate local folders instead. For incoming mail, I use server pop.juno.com on port 995 with SSL/TLS security and encrypted-password authentication. For outgoing mail, I use server smtp.juno.com on port 465. Every time I send mail, the following messages appear: There is not enough disk space to download new messages. Try deleting old mail, emptying the Trash folder, and compacting your mail folders, and then try again. which is inaccurate, given I have a considerable-sized hard drive (500 GB), plus multiple USB drives with much more space... then comes: Your message was sent but a copy was not placed in your sent folder (Sent) due to network or file access errors. You can retry or save the message locally to Local Folders/Sent-bob.in.jersey@juno.com. with the choice of buttons Retry, Save, or Don't Save. Please do something about this, or tell me what I need to do to ensure that the messages go to where they're supposed to go. Thanks.

I have tried for years to get my main email address to work in thunderbird. I have 3 email accounts, two work great but my main one creber887@sbcglobal.net just keeps giving me server errors. I have no problems in firefox on yahoo. It is frustrating. It happens in windows and linux. Please help. Clark Creber

I am trying to set up a new email address on Thunderbird but comes up as a POP account. I then set it up on another computer and it comes up as IMAP. I have tried setting up the IMAP manually but Thunderbird rejects. I have uninstalled the app and re installed it.
