Forum Thunderbird zajednice

I'm having an issue with some of my filters not working. I've checked the several times and they should be set up correctly, but, for some reason, they don't perform their respective actions, even when I press "Run Now".

Also: I recently changed the sorting of my e-mails to be threaded by chain. I like to have all of my most recent e-mails show up at the top, but, within each thread, the most recent e-mail shows at the bottom (see the supposedly-attached image). Is there a way to flip this?

Thank you in advance.

After deleting an email (GMAIL) from any folder and emptying Trash, the email is still in "All Mail". Deleting from "All Mail" and emptying Trash still leaves the email in "All Mail" - in fact, selecting the email to be deleted in "All Mail" and then selecting "Delete" causes them to disappear and then reappear. This used to work correctly. Using !39.0.1 64 bit version. Note: I recently had to reinstall Thunderbird after a systems issue - causing me to reinstall Windows 11 and noticed the problem after that. It might be that the GMAIL "Trash" folder has been linked to "All Mail". I can delete the emails by signing on to GMAIL on the web and deleting them that way.

Do the Thunderbird developers go out of their way to make the look and feel of Thunderbird ugly. How about some easy way to add some colours? The three themes are just plain grey. I hate Outlook but at least the colours make finding things easier.

I tried to use the Thunderbird Import function but it won't allow me to tick the Calendar function. If I can't import my calendar from my outlook program then I can't use Thunderbird. Very frustrating.

I am using MacOS 10.13, Thunderbird 115.15.16ESR: my Hotmail worked until 15 May 2025 and then it would not download new emails. Screenshots are available if you want me to post them. I got an error message: "authentication failure while connecting to server outlook.office365.com". I updated Thunderbird to the latest for my OS: 115.18.0ESR. Still no new emails. I deleted my email account on Thunderbird and tried to reinstate it. Now I get an error message when trying to set up the account: "Unable to log in at server. Probably wrong configuration, username or password." I tested my password by logging into my Microsoft account with it on my browser. I can also login to my email using Firefox, but I want my Thunderbird email client to work again.

The configuration I am using is: I use my normal hotmail password in the password field. I also set up a new App Password with Microsoft and tried that without success. With the 115.18 update there is a new field: Your login. I just put my hotmail email address in here. incoming: outlook.office365.com, port 993, SSL/TLS, Oauth2 
outgoing: smtp.office365.com, port 587, STARTTLS, Oauth2 (I have also tried: smtp-mail.outlook.com)

I enabled 2-step authentication with Microsoft in my Microsoft account more than a year ago. Interestingly, I don't get a prompt on my iPhone Microsoft Authentication App when I select Done when trying to set up the hotmail account on Thunderbird.

Please help. I am desperate, and I have wasted a lot of time on this without success. Cheers

I have an old Thunderbird account that is no longer active but I have a huge archive of emails that I would like to be able to access. Thunderbird takes up a huge amount of space on my nearly full C drive because of this. Is it possible for me to save the archive on my D (data) drive and just have the program on my C drive. And how can I back them up. Thanks!

Thunderbird 138/139, Windows 11 Pro 23H2. While composing a message, after a few lines the app freezes. Both the compose window and the main TB window freeze. Only opening the Windows Task manager allows me to close them. This did not happen with earlier versions.

If I save the message every few seconds while composing I can get most of the message back and continue after restarting TB. This behavior is the same in both the normal and troubleshooting TB modes. I can't even find a crash log to send to Mozilla.

Where shall I look next?

Thank you!

Amazing that there is no topic for Spam, the most hated aspect of email. Mozilla, wake up!

Anyway, I want to be able to highlight a bunch of spam emails, then block all the domains they are being sent from, first checking to make sure nothing was sent from a legit domain like Gmail or Hotmail. Because the smart spammers acquire domains from which they can generate an untold number of email addresses from and they can just a different one every day so blocking an individual email address from someone like this is useless. They'll never use the same one twice because it's so easy to use another one. They own the domain so they control everything at that domain.

I've never heard of any email program offering this which is perplexing as this is the only logical solution to the vast majority of spam we are plagued with in 2025.

We really need an Add-On for Thunderbird as it appears Thunderbird doesn't seem to care.

Hello, Mi 9 SE with MIUI 12.5.1 Android 11 RKQ1.200826.002 Thunderbird 10.0

I moved from K9 to Thunderbird some time ago without incident. In the last few days I realised I had received nothing and checked on my PC and indeed mails were waiting. I tried to send a test mail from the phone, the mail remained in the OUTBOX and I received the following error message :- "Failed to send some messages ErrnoException: connect failed: EACCES (permission denied)" I checked and this is an Android error and various articles I found that suggest necessary changes to the manifest which I am not capable to change; I am not a coder. I decided to save the configuration, delete and reinstall Thunderbird. After this and reapplying the passwords the waiting mails were delivered. I then tried to send a test message from the phone and again the same error was generated with the phone blocked again from sending or receiving.

I suspect that there was an upgrade applied with a changed manifest that broke the operation of Thunderbird with Android 11.

Can someone please verify this, it may be impacting many installations on older phones?

Many thanks!

Incoming e-mails do not always appear in the inbox when they arrive. They always do appear but there are often delays, sometimes of a few minutes, sometimes of several hours, and sometimes of many hours. At the end of the delay they always do appear, with the time at which they were sent indicated, even though that time is earlier than the time at which they appear in my inbox. I have sometimes sent e-mails to myself, as tests -- and these are also often delayed for five or ten minutes. I am not aware of any actions that I take that precipitates either the start or the end of the delay.

Beginning on May 19,2025 my email will no longer download from centurylink to my Thunderbird program/account. I've tried talking to both centurylink and brightspeed that took over centurylink. They were completely clueless.

I have downloaded my ICS file. I come to Thunderbird and it appears to import. And, in fact, some stuff seems to have imported. But then it stops at about 10% and gives me a message I've gone to the tools, developer tools, error console and I HAVE NO IDEA what it means or what I can do next ...

see attached.

I really don't need most of this stuff, so I just want to import most of it.

right now it appears a partial import has happened. but the error stopped it from continuing.

Several years ago, I switched over to the beta path of Thunderbird... In doing so, I created a new profile for the beta installation, leaving the old one behind in case I wanted to abandon beta... So I had two profile folders; I *thought* they were this:

current profile: c:\notes\Thunderbird original backup profile: c:\notes\Thunderbird.b115

Now, I've decided that there is no reason to retain the old Thunderbird profile folder, since I'm clearly committed to the beta path... however, I have discovered an anomaly... *both* the old and new profiles are periodically being updated!! Thunderbird.b115 is apparently actually my active profile, but Thunderbird was updated just a few days ago.

When I look at About Profiles, I actually see *three* profile folders listed:

Profile: Gorlash: (default: no) c:\notes\Thunderbird

Profile: Derell Licht beta: (default: no) c:\notes\Thunderbird

Profile: Thunderbird beta (default: no) c:\notes\Thunderbird.beta (note that this folder does not exist)

Profile: Thunderbird b115: (default: yes) c:\notes\Thunderbird.b115

===========================================

Is there something that I could do to consolidate all of this into just one folder? I don't even *know* what those Gorlash and Derell Licht profiles refer to... Yes, those are both usernames that I use online, in various contexts, but as far as I know, I don't use them in Thunderbird...

Q1: Can I just delete those other profiles where default is NO ?? Q2: Why is c:\notes\Thunderbird still getting periodic updates, even though those profiles are not default??

I recently started using Thunderbird to back up my emails, but I accidentally forgot to remove the Delete emails after transfer checkmark and all the emails on the original server (Yahoo Mail) were deleted.

I contacted Yahoo, but it seems impossible here, so is there any way to revert it on the Thunderbird side?

In the meantime, we are working on restoring the necessary emails from Thunderbird by forwarding them again.

Long story short, I accidentally created 100% duplicate entries in one of my address books. I'd like to run a program to either consolidate the entries or eliminate the duplicates.

I do have more than one address book, and in the bast-case scenario, I'd be able to consolidate across all address books so I end up with just 1 "address" per entry.

I checked on the web for help but all suggestions seem to refer to options no longer available to my version of Thunderbird [138.0.2 (64-bit)].

Can you help?
