Thunderbird Community Forum

After I set up my IMAP and SMTP settings for my iCloud email account in Thunderbird I click my inbox and a prompt to donate comes up. I ignore that and focus on the second prompt to input my password. I had already went into my Apple iCloud account and created a third party account password. I thne input the password. It continually rejects that password. I am thinking that the prompt for a donation may be interfering. Also, prior to the password issues the app was running very slow. I went online and blocked Thunderbird from my contacts and that seemed to work. Could the issue be one of the inputs for my incoming and outgoing settings. I ran the test in IMAP and things looked good for the test. But always, the password fails. Please help.

Sometimes when I am send an email to 3 or more people, such as a Christmas letter, I will get a message that the "server" has determined that this is spam, and rejects the email. I have found that if I send the message to one or two people it will go through. I am not sure what server it is referring to or why it is considering it spam. My email account is with Cincinnati Bell (now AltaFiber) and they are "fuse.net" accounts. I always assumed that the mail came and went through their servers.

Hi All,

Just wondering what the roadmap is for multisearch functionality?

I might be a bit dim, but how do you actually search the support forums, as I suspect that this question has been asked before. There are no results returned for multisearch or RFC 7377 or ESEARCH.

Also is it possible to return search results as a vertical list instead of tiled responses, there's a reason why google doesn't do this.

I'm using Thunderbird 140.6.0esr (aarch64) on a 2024 14" MacBok Pro running MacOS 15.7.3 (24G419).

I manage fourteen email addresses, with most of the traffic going to one primary account, either by direct addressing or forwarders from others of the addresses. Maybe not the most efficient setup, but it means I don't have to scan 14 different inboxes to find the messages I most need.

I currently use ±89 filters on this primary account to file messages in a LOT of mailserver-based folders, and a few folders on the laptop. ±90% of the traffic gets filed in server-based folders so I can use any device to access message history. (I should probably note that these filters and message-threading don't always play nice together.)

For a long time, one message filter successfully filed specific messages in a particular server-based folder 2 levels below the inbox - I'll call this sub-folder BS for the name of the project it hosts (it's not what you're thinking...). BS also has 2 levels of sub-folders within it for annual and monthly filing.

Some time ago, I began to have problems with messages of many kinds (subjects/sources/etc.) going missing. Eventually, searches found them filed in the BS folder. In response, I deleted the BS message filter, looked for but didn't find other filters responsible for these unexpected results, and managed incoming BS messages manually. But at this point, so many messages get "lost," then turn up in the BS folder, it is acting like a black hole, sucking up too much traffic for manual refiling to be viable.

Speculating that something's "off" with the BS folder's directory in a way that would be nearly impossible to fix, I'm trying to figure out the least inconvenient, least risky way to solve the problem.

Not knowing other ways I might compound the problem by making big moves with the MANY messages archived in the BS folder's 7 annual subfolders and their 12 each subfolders; and not knowing how to back up server-based in-box sub-folders, I'm stuck at an impasse.

How should I proceed?

Thanks in advance for any input.

I was working with thunderbird today. Was in a specific email folder I had named "reference" that I use to store various emails, probably around 50 emails in there. Suddenly they all deleted from the folder as I was watching the screen. Checked spam/trash folders and nothing. Also logged into my webmail provider and nothing there either. Any idea what could have happened here? They just seem to have literally vanished. Have used Thunderbird a number of years and never experienced anything like this.

I was using Thunderbird Portable 136.0.1, from Portableapps.com . I then upgraded it to Thunderbird 146.0.1, by following Portableapp's instruction of installing the Portableapp 146 version to the same path of the old installation.

I then I added an Office365 Business email account to Thunderbird, but there was a problem with the SMTP configuration. I tried to change it, but then I found out that there's something wrong with my Account Settings for all accounts; they don't save the changes.

Let me explain: if I right click an account and choose "Settings", a new tab opens [image 1]. Whatever changes I make there, to "Account Name", "Your name", "Color", etc. don't get saved; as soon as I switch to another account and come back they are gone.

This also applies for "Edit outgoing server..." at the bottom. It always reverts to "Default server" and then every time I want to send an email I must change the default SMTP settings to the right settings of that specific account.

The "Delete" button for deleting the account also doesn't work, if I click it nothing happens.

Interestingly, if I switch to "Server settings" or "Copies and folders" the changes there do get saved and are displayed correctly for the different accounts.

What can I do to solve this? I already tried Troubleshooting Mode to no avail. I am currently trying to install Thunderbird Portableapp to a different folder, how can I then import all local folders and accounts to this new install?

I used to get my emails from IMDp on my email account. I am not sure what I did to change something but I can no longer get emails.

What did I do to screw this up? Where do I go in the help list to get my emails back?

Thank you

we are unable to sign into tundsrbird using correct creditials. we worked with geek squad and they senr our mail to webnet. the tech told us we would not lose any email that were in thuderbird. when we ckecked they were all gone. there is very inpotant information in there. We would like to restore thunderbird and retrive our lost emails.

Recently my Thunderbird mail has been 'glitchy'.

Sometimes I receive audible alerts for emails, other times I don't.

Sometimes the number of new emails received is correct, other times it shows 4 new emails when, across all my accounts, the number is 2 (for example).

Are either or both of these known issues?

I also noticed when I was watching a live music stream on TikTok last week, I 'had' no emails for almost 2 hours. As soon as I left TikTok and closed my browser window emails 'arrived', one timestamped 45 minutes earlier. The settings for that account are set to check for emails every 5 minutes.

Could the Chinese be 'watching me' 😁 or is there another more innocent explanation?

Hello, My SMTP server uses Let's Encrypt certificate. The website with the same domain has no certificate. Thunderbird refuses to connect to my SMTP server. Test connection to the server (STARTTLS) in account settings sais "The secure connection to the server failed" (or similar. I see bg localization). Another server with Let's Encrypt certificate. Test pases. Clicking View certificate shows webserver cert (from DigiCert Inc).

I can't send emails! :)

I have just installed Thunderbird for my wife on Fedora. She is struggling because she relies on her program (formerly mac Mail) 'knowing' the addresses of contacts and autosuggesting when she types the first few letters. Obviously with a fresh install of TB, it doesn't 'know' any of her contacts. Is there a way to make it learn from the Sent Items folder? So that it auto adds all addresses she HAS SENT TO (in the past), to her contacts/address book? Thanks

Nach der Formatierung einer Tabelle verbleiben rote gestrichelte Linien um den Zellen der Tabelle. Diese Linien werden auch gedruckt. Wie kann das vermieden werden?

Why suddenly has Thunderbird stopped logging my messages that I filter manually even though I have logging enabled? It used to work just fine. It no longer logs ANY message filtering. I have not changed any settings. I depend on it especially to confirm that new filters I set are working properly. How can i fix this?

I get a pop up message from Thunderbird stating the the connection to server pop.earthlink.net was reset. I have to reboot my PC to be able to download emails. Is there a setting I need to change? Thanks.

I use Thunderbird 115.18.0 on a Windows 7 machine. I wish to transfer all my Thunderbird data to a machine running Linux Mint 21.3 which has Thunderbird 128.12.0esr. I have not been successful after many tries. Could this be because the Thunderbird revisions are different? If so, can I get 115.18.0 to install on my Mint machine? If not how should I proceed? I have already tried creating a new .thunderbird directory with ********.default directory from the other machine. I have also tried a new .thunderbird directory with a the ********default-release directory as directed by one site.

Sorry - I feel as though I'm monopolising this forum at the moment!

In my Menu bar, I have Delete, but, using this, I can only delete emails from the Unified list, not individual accounts. I CAN delete from individual accounts if I select the email, right click and select delete. Seems odd

The folder 'Outbox on Local Folders' could not be compacted because writing to folder failed. Verify that you have enough disk space, and that you have write privileges to the file system, then try again.
