I apologize for the unhelpful summary line, but I am totally new to Thunderbird and the Unified Inbox is acting so strangely that I don't have any simple way to describe it.

Many (but not all) of the emails are displayed twice in the list of messages.

When I delete a message that isn't doubled, the message disappears from the inbox (as it should).

But when I delete one of the doubled messages ONE disappears as it should and on the other Thunderbird clears the From and Subject fields and changes the date to 12/31/1969, 19:00 -- the changed entry stays in the list and the body of the email is still shown in the lower pane. The only way I can get rid of the message is by selecting another folder (ANY other folder) then when I return to the Unified Inbox the deleted messages will be gone from the list.

I can't believe that this is how Thunderbird is supposed to work, so I assume I have something configured incorrectly (although nearly everything is still at the defaults that the installation gave me).

Incoming messages are interspersed with old messages without any order. I tried to corrrect this by pressing "date" in the installation column to the right, but that does not help.

Thunderbird: Suddenly links in emails are behaving very strangely. Whenever I click on a link, the Inbox window is selected and the link is essentially ignored.

Here is an example: At this site

   do-not-reply@stackoverflow.email

when I click on "Special partition of the set $[n]$" the Inbox window comes up. Copying the link, I find it is this:

   https://sg-links.stackoverflow.email/ls/click?upn=u001.

This is over 700 characters long, which seems a bit strange.

Any info on fixing this will be greatly appreciated.

Is there a way to create a Thunderbird account even though your system is not able to log into my iCloud.com email account using my credentials?

Hello. My email account with you is not receiving emails. But I did test for sending emails and it seems to work? Can you look into this please? x@windstream.net

I am unable to find the Archive folder. It is not listed when I right click on the account name. All of my folders are there but not the Archive. Any one know how to deal with this?

"Dear Support Team, I am trying to configure my email account (gennadij.tolkachev@digitranslab.com) in Mozilla Thunderbird, but I am encountering an issue. The automatic configuration fails with the message: "Thunderbird failed to find the settings for your email account." When I proceed to the manual setup screen, the Incoming Server field is pre-filled with ".digitranslab.com" (including the leading dot). The application rejects this, stating that the server name is empty or invalid (it says: "Server name is empty or incorrect. Only letters, numbers, - and . are allowed"). Could you please provide me with the correct manual server settings for our mail server? Specifically: Incoming Server (IMAP): Server hostname Port Connection security (SSL/TLS, STARTTLS, or None) Authentication method Outgoing Server (SMTP): Server hostname Port Connection security Authentication method Thank you for your assistance. Best regards, Gennadij Tolkachev"

Hi. I have a problem since few months ago about the following fact: when i want to move emails from inbox to a specific folder, i am using "recent destination" option, but the folders doesn't appears anymore in alphabetic order. I have attached a screen shot with "recent destination" list of folders and currently they are not listed in alphabetic order anymore. Can you help me to fix this issue?

Thank you!

Hello, I have tried to send several email replies using thunder bird but they fail because the smtp server times out. Or cannot be reached. I am a new Starlink subscriber and am wondering if that could have anything to do with the issues. The software is on my dell computer running windows 10. Any help or suggestion is appreciated.

My wife's inbox has over 24,000 messages. I'm moving messages whose senders are the most frequent to folders. This ends up having to move over 100 messages at a time, which is taking forever. Has anyone found a faster way to move multiple messages into one folder?

Hello all:

After migrating to a new machine I finally have TB set up and running nicely. As I checked the individual settings and C: folders for the e-mail accounts under the server settings for each account (there are two, law and business), and the local folders (for long term e-mail storage, under Local Folders, Local Directory settings), I discovered the C: folder for the Law e-mail account is gigantic - when I check the properties in File Explorer it comes back as 331 GIG, yes, gig. More disturbing is that most of this appears to be "dark matter" that does not "show up." I total the visible files and folders inside that location and it is roughly 150 meg.

For comparison, the folder directory for Business e-mail account is only 24.9 gig, and the directory for the local folder for long term e-mail storage only clocks in at 11.1 gig.

Any ideas why the law firm e-mail account C: drive storage would be this large, with so much of it not visible?

Thanks for any thoughts.

Translation: My emails in Thunderbird suddenly disappeared.

They were over 10,000, but now they're down to only 7,800.

Why?

Hello, so finally this happens to me too. I lost all my emails in Inbox before August 2025. I think it happened after one of these usual alerts 'you should compress emails'. I did this in the past 6, 7 years and nothing was lost so far. I also have plenty of space on my computer, that's not a thing. I tried a couple things I found in web but doesn't help. Couple emails that I had for example in an 'important' folder are still there. I'm really annoyed. I didn't had a glue at all that this compression alert will delete files in the inbox one day, only those in the trash box. Maybe there is a last chance to get them back but I'm afraid that they are gone forever and I will put everything from my inbox into an other folder in future or maybe even better go back to Apple Email where this never ever happened in the past 25 years.

Thank you, Chris
