Thunderbird Community Forum

Hi! Since I've installed Thunderbird on my new computer with Windows 11, I've now twice experienced the disappearance from my inbox of a bunch of emails. Never had this before with Thunderbird. Could it be something needs doing in Settings (I couldn't find any relevant options)? The emails weren't among the newest, but they were all important.

Hello everyone. Thanks for all your support.

A few weeks ago I started noticing a pop up window was occurring every (approx) 5 minutes in Thunderbird suggesting that I run a compact to save 992MB. I assumed this would stop happening after a few weeks and a few updates from Mozilla, but the problem has remained, so I'm coming here to ask about it.

Context: I'm on Windows 11. I have multiple email accounts that my Thunderbird reaches out to. At least one of the accounts is retired so reaching out to its historical server fails.

Reproducing: For me to reproduce it, I run the compact. Quit Thunderbird. Start Thunderbird. It reports 992MB can be freed. I let it compact. The main inbox disappears and reappears. I wait a few seconds and restart Thunderbird. It again tells me that it can save 992MB by running a compact.

What I've tried: I've tried repair on the inbox folder of the account I'm typically in. That didn't help. I have many other folders across many accounts and not tried to repair any other folders. I've searched the Mozilla help system.

Logs: It seems to me that a compact is probably failing but I don't know where to look for evidence of the failure.

I have created a new gmail address for my wife. Would like to add this address to my existing Thunderbird Mail account so that her emails also come to my Thunderbird email account. Not sure how to add her address to do this.. Thanks

My routine login to my Apple e-mail account just failed. neither my new Apple ID password or my old special T'bird Apple mail password xxx-xxx-xxx-xxx works.

What changed and how can I fix it?

[edited from public] @icloud.com seems to be working on Apple Mail, but T'bird won't connect...

Help. Help. I have been a very happy Thunderbird user for many years. I have linked my microsoft exchange calendar to thunderbird with the TBSync and Provider for Exchange ActiveSync.

With the upgrade to version 148, those add-ons no longer work.

So I downgraded to 140 ESR and those two add-ons were ok.

But when I tried to link them to my calendar, they would not sync. I received 401 and 403 errors from the automated setups. And the manual setup, asked for my password over and over again. They all worked beautifully before.

Please how can I get them to work again. I do not want to have to shift to outlook.

thank-you

Hi folks

When I tried to start up Thunderbird this evening, it has taken me to a set-up page. I seem to have lost all the settings, all my previous (about 3000 !) e-mails in my Inbox.

I obviously don't really want to set it all up again, but it has been working for years without a problem, and then suddenly this happens. I had now a 'warning' message saying that Mozilla Thunderbird wants to make changes to your computer - do you accept? I don't want it to make any changes unless it is to revert back to how it was.

Can anybody help me?

Thanks.

Linux Tbird 140.7.1esr (64bit) running under Ubuntu 22.04, and with imap on all my email accounts. I normally manage emails locally in Tbird, hardly ever go to webmail.

In my list of Local Folders, there are two which show up with the name 'Outbox' and identical icons. Viewing each folder's Properties, the name Outbox is unsurprisingly given for both, but their locations are different: mailbox://nobody@Local Folders/Unsent Messages mailbox://nobody@Local Folders/Outbox

1. Are these two folders supposed to have the same purpose? One (or both) must be for the [in my case extremely rare] situation where I compose an email but its actual sending is frustrated (eg router turned off).

2. I cannot rename either folder, eg by attempting to edit the Name field when viewing the properties box. If their function is distinct, being able to change the name to reflect this would be nice.

3. If the purpose is the same, presumably only one is actually used by Tbird. Which one? Can I delete the other, and if so how - just in case Tbird would automatically recreate it?

Not a big deal - this has been the situation for a long time (brain fog stops me remembering just how long) - but this is untidy and it niggles.

Ich habe ein Update von meinem Tunderbird Konto gemacht. Meine Software ist Windows 10. nun habe ich keineUnterlagen mehr. Was soll ich tun. bitte um Hilfe. Bin bereits82 Jahre alt und habe keine Hilfe.

This happens each time I open up T-Bird. Somtimes it is Yahoo.mail, sometimes it prompts to log onto aol.mail.com.

How can this be stopped?

I know TB used to have a command to search for duplicate messages. Now, after installing the program again, I cannot find this command anymore. Why? Is it me or has it been removed? Thanks.

Today I have experienced a problem downloading new messages, bulk, trash or anything else in my mail server into thunderbird. it requires my primary password and then my regular password. I just set up my primary password so I understand why it is asking for that, but I don't understand why it is also asking for my regular password before I can get access to the mail server that I am using. the regular password was set up on 6/17/24 and until today it was working fine.

Hello, my email account works fine, but my wife's account keeps getting the message "Unable to write the email to the mailbox." The message at the bottom of the screen says that there are 56 emails to be downloaded from the host, but the error message does not allow the download to occur. Thank you for any assistance. John.

I have 2 Verizon accounts in Thunderbird. One of them works fine, the other one gets the emails that were sent to the first one. It's like there is a forwarding address sent on the first email that is sending them to the second one. I removed the accounts completely, uninstalled and re-installed the Thunderbird and I still have the same problem. On webmail, on aol.com, the email addresses work perfectly fine.

I have Thunderbird working well on my desktop. I am trying to add it to my laptop. I am unable to get the setup accepted. the message I get is failure likely caused by wrong name or password. The name and password obviously work on my desk top computer.

I've been trying to move my Thunderbird data (148.0) from a Win10 to a Win11 machine. I've meticulously followed both the methods outlined at http://mzl.la/1ApHiU3. I have copied my original profiles.ini from the ...AppData\Roaming folder to that location on the new machine, then corrected the drive locations in the file (see attached profiles.ini image). (yes, the correct "j4sqsccb.XXXXXXX" folder is copied to the new installation's root: a bulky several-GB)

In order to try to replicate my original computer's admittedly-awkward installation from long ago, I have added the suffix " -p -no-remote" to the desktop icon's Target field. And on startup, the new T-bird does properly show my original profiles in the Select panel - even though I only ever used the one that functioned correctly, identified as 1 in the profiles.ini file (see Choose User Profile image, IDs X'ed-out).

However, on selecting that profile on the Win11 machine, Thunderbird just takes me to the account setup screen, as if it's unable to locate or load the account settings for that profile.

I'm only doing this clunky method of copying-over out of ignorance; I'd be very happy to simplify the mess I'd created decades ago with my original installation. OR if you think I'm better off wiping all evidence of past installations to start from a clean install, I'll be happy to do that. Please let me know if you need additional info I've failed to provide here!

Also adding images of my ...Roaming\Thunderbird\Profiles folder and Installs.ini file, just in case!
