Thunderbird - Why Does the Dark theme have black writing on a black background?

I have eye issues so a glaring white background is difficult for me but the theme I used to use the dark mixed system one (or dark one) has black writing when I try to look at details in my 'Tasks' and calendar details, why is this?

I am working with thunderbird on two locations and have problems moving contents between address books and entering new contacts into address books.

On location A I have created a mailing list X under my personal address book. I could fill it by copy/paste address and name from mails received. Then I created a cardav address book Y and somehow (ctrl + left mouse?) succeeded to drag and drop the entries from X to Y and synchronized it with a nextcloud cardav file.

Now I went to location B, created a cardav address book with the same credentials as on location A and got the Y addresses synchronized.

So far, so good.

Then I tried to enter new addresses in location B into this Y online address book. Problem - I could not find a way to add new contacts into a line with copy/paste like into the X mailing list in location A. New contacts could only be added via the "New Contact" form, no copy/paste.

Then I created a mailing list in my personal address book with the same name X. I could not find a way to copy the content of the online address book Y into this list (on location B). When I tried with ctrl-left button drag and drop, the target mailing list X was forbidden. Only copying to my personal address book would be possible. But at least this mailing list X offered again the copy and paste possibility in one line, but unfortunately the list was empty.

Then I tried it with export/import. I exported Y from the online book to a vcf file on my computer, then tried to import the file to my mailing list X, but I could not find a way to import the file to the mailing list X.

I can create a new address book and move the contents of the cardav book to it. But adding new contacts is possible only via the "New Contact" form where I cannot just copy/past addresses from emails.

Any suggestion how I can work with my mailing list contacts on both locations and easily enter new contacts with copy/paste from mails without having to use the form?

can not get my email account a us.exg7.exghost.com set up inTthunderbird. acts like it set up the outgoing server but not the domain or in comming server.

11/1 I had dozens of folders, thousands of e-mail, and probably two dozen rules. It was all gone. I restored connection with my vendor's IMAP server and after a day of downloading everything. It took so long I never was able to work. 11/2 I brought up Thunderbird to see what looked like a full Inbox, but no folders. I also had my rules restored. Again, several thousand e-mail had to be downloaded, since only their subjects displayed but no content when any message was clicked. 11/3 I was unable to work, so today 11/4 I opened Thunderbird to see my account with profile details (server info, etc), but no folders, e-mail, nor rules, but no response when I try to download e-mail. Testing the server link succeeds. I do not understand some of these articles on profile, since I have nothing they seem to refer to. I think I see a profile (original???), but Thunderbird doesn't seem to. Account is complete...

Auf der Öffnungsseite erscheint normalerweise links ein schmaler Streifen mit den ganzen Ordnern, wie Posteingang, gesendet usw. mit der jeweiligen Anzahl der E-Mails. Im übrigen Feld rechts daneben sind alle E-Mails einzeln aufgeführt. Jetzt erscheint manchmal auf der Öffnungsseite eine andere Ansicht, ähnlich wie die Konteneinstellungen. Mit mehreren Versuchen kreuz und quer gelingt es dann wieder die normale Ansicht zu erhalten. Vermutlich habe ich mal irgendeine falsche Taste gedrückt, so daß sich die Ansicht plötzlich geändert hat. Könnte sich das Problem lösen, wenn ich Thunderbird neu installiere oder gibt es eine einfachere Lösung?

I had to upgrade my phone and in the process the passwords were lost. Starting over. Now I cannot adjust thunderbird to get anything. It is supposed to go to an area allowing password update but all I get is a blank screen. Any help is appreciated.

Over the past few days, the format for emailing seems to have changed on my PC, an error message keeps coming up saying: Error occurred connecting to imap.talktalk.net, I have tried to follow Google advice but it doesn't seem to have made any difference, I can still send and receive emails, but have to wait for all my old emails to load before I can do this, I'm a novice and a pensioner, please help Thank you

show me how I can persuade Thunderbird to recognise my mail address, as it always has in the past. This started on 17 October, when internet hacks were reported. Possible connection?

With Google traduction: I've changed my password four times using an Infomaniak email address ending in @ik.me, and it's never recognized! What should I do? Thanks.

I am a bit of a noob, and probably out of my depth, so please bear with me. It also is a bit of a confusing situation so I hope that I can explain it clearly.

A while ago, Thunderbird stopped working. Whenever I tried starting it up, I got an error message saying that Thunderbird wasn't responding. I thought there might be a problem with some update so I decided that I would reinstall the program. As I went to back up my profile, I found out that there were actually two profile folders where in the past I would only find one. I chose to back up both, and procede with de- and re-installing Thunderbird. After doing so I tried to integrate the old profiles back into the new installation. At first, I chose the largest of the to profile maps and copied it where I found it before the re-installation. I created a new profile using the old profile folder through the User Profile menu. This seemed to work! However, I noticed something. I have two e-mail accounts running in this profile. One IMAP and one POP. I noticed that the POP account was missing about a years worth of old e-mails. As if it stopped saving them at some point. I figured they must be in the other profile folder I found before the re-installation. I tried creating a new profile with this profile but when starting up Thunderbird afterwards I once again got the 'Thunderbird isn't responding' message. So I reverted back to the first profile I made, the one with the missing e-mails. Appart from those e-mails, it seemed to be working well. To get back what was missing, I tried copying the files in the "inbox.sbd" of the back up that wasn't responding into the back up that was responding, thinking that if it messed something up, I could just CTRL + Z my way out of trouble. It seemed that there were three locations in the functioning back up that I could copy the files into, each having the server name of the e-mail account that I was missing e-mails from. I tried copying the files in each of them, each time removing the files through 'undo' before trying the next location. As this seemed unsuccesfull I tried restarting Thunderbird again (having removed the copied files from all locations) which resulted in the following error message:

In a pink screen that I have never seen before. After this I tried removing all profiles and starting again with a fresh copy of the backed up profile folder as I figured I might have accidentally changed something in the profile folder I was using. This however keeps giving the same error message.

Clearly, I messed something up. But I don't know what. Can anybody help? One last thing I noticed that in the 'Mail' folder within the profile folder, there where three folders with the server name before, now there is only one. I guess this is a clue?

All help is welcome!

1. 1. Thunderbird connects to my IMAP/SMTP server but neither receives nor sends mail

I am having a problem with Thunderbird on Windows with a custom-domain email account hosted by Advika Web.

1. 1. 1. Account

Email address: `connect@synergyappstudio.com`

Mail hosting provider: Advika Web

The mailbox and password are confirmed to be valid because I can successfully log in to the provider's webmail using the same email address and password.

1. 1. 1. Server settings provided by the hosting provider

Incoming IMAP:

• Server: `mail.synergyappstudio.com`
• Port: `993`
• Connection security: SSL/TLS
• Authentication: Normal password
• Username: `connect@synergyappstudio.com`

Outgoing SMTP:

• Server: `mail.synergyappstudio.com`
• Port: `465`
• Connection security: SSL/TLS
• Authentication: Normal password
• Username: `connect@synergyappstudio.com`

1. 1. 1. What happens in Thunderbird

Thunderbird shows:

> Connected to mail.synergyappstudio.com

However, incoming messages are not downloaded and outgoing messages cannot be sent.

The SMTP error I received was:

> The connection to Outgoing server (SMTP) mail.synergyappstudio.com timed out.

1. 1. 1. Connectivity tests

I tested the server from Windows PowerShell.

Port 993:

`Test-NetConnection mail.synergyappstudio.com -Port 993`

Result:

> RemoteAddress: 103.69.196.146 > RemotePort: 993 > TcpTestSucceeded: True

Port 465:

`Test-NetConnection mail.synergyappstudio.com -Port 465`

Result:

> RemoteAddress: 103.69.196.146 > RemotePort: 465 > TcpTestSucceeded: True

Therefore, both TCP ports are reachable from my computer.

1. 1. 1. TLS tests

I also tested the actual TLS handshake rather than just TCP connectivity.

TLS 1.2 against IMAP 993 failed with:

> Unable to read data from the transport connection: An existing connection was forcibly closed by the remote host.

TLS 1.0 against IMAP 993 produced the same result:

> Unable to read data from the transport connection: An existing connection was forcibly closed by the remote host.

I also tested the TLS handshake against SMTP 465 and received the same "connection was forcibly closed by the remote host" result.

1. 1. 1. Comparison with Outlook

There is an important comparison:

The same mailbox **successfully connects and authenticates in Classic Outlook** using the same server and credentials.

However, I am using Microsoft Office Home & Student, so Classic Outlook is not available to me as a practical permanent solution for this business email account.

Microsoft's **New Outlook** also fails to add the account and displays:

> Sign in failed. Please try again in a few minutes. You may need an app password.

The mailbox does not use Microsoft 365 authentication. It is a conventional hosting-provider IMAP/SMTP mailbox.

1. 1. 1. Thunderbird troubleshooting already attempted

I have:

• Confirmed the password works through webmail.
• Confirmed the supplied IMAP/SMTP server names.
• Confirmed ports 993 and 465 are reachable.
• Confirmed SSL/TLS settings.
• Used Normal Password authentication.
• Used the full email address as the username.
• Tried Thunderbird with the supplied IMAP/SMTP settings.
• Reduced **Maximum number of server connections to cache** from the default 5 to 3 and then to 1. This did not resolve the problem.
• Restarted Thunderbird after changing the connection-cache setting.
• Tried Thunderbird's connection logging, but the generated log files remained 0 KB, so no useful log was produced.

1. 1. 1. Additional observation

Thunderbird displays "Connected to mail.synergyappstudio.com", but the account does not actually synchronize incoming mail.

The provider's webmail works normally, and Classic Outlook works with the same mailbox.

1. 1. 1. What I would like help determining

Could you please help determine whether this is:

1. A Thunderbird IMAP/SMTP compatibility issue with this particular mail server; 2. A TLS negotiation issue; 3. A Thunderbird configuration/profile issue; 4. A Windows/security-software interaction; or 5. Something specific to the mail server's IMAP/SMTP implementation?

In particular, I would like to understand why Thunderbird can establish the connection but cannot complete the IMAP/SMTP communication, while Classic Outlook works with the same server, ports and credentials.

I can provide Thunderbird version information, Troubleshooting Information, screenshots of the account configuration, or any additional diagnostic information you need.

Just tell me how to stop Firefox classifying my received e-mails. I've tried to change the settings but nothing seems to make any difference. I resent this sort of AI interference.

In einem meiner Postfächer sind alle Unterordner verschwunden unter TB. Auf dem Handy kann ich alles sehen, in anderen Postfächern auf dem PC stimmt alles.

Ich habe alle verfügbaren Tips probiert seit ca. 4h.

Im Verzeichnis von heute scheinen alle Daten vorhanden zu sein, siehe Bild. Die Dateien und Ordner von gestern sind aber grösser, siehe 2. Bild. Im Postfach auf TB sind sie aber gar nicht zu sehen.

Was tun?

Gruss, Dirk

Normalerweise habe ich die klassische Ansicht, links die Ordner mit der jeweiligen Gesamtanzahl der E-Mails und rechts alle E-Mails einzeln mit Text aufgeführt. Jetzt seht das nach dem Einschalten von Thunderbird so aus: links nur teilweise die Ordner ohne der Gesamtzahl der E-Mails und rechts eine Ansicht ohne alle E-Mails und nur einzelne Nachrichten, wie Neue Nachrichten verfassen, Nachrichten suchen,Filter für Nachrichten verwalten usw. Manchmal kommt aber die richtige klassische Ansicht zurück, wie jetzt gerade, später ist diese Ansicht wieder weg für längere Zeit. Ein Benutzer hat mir schon geantwortet. Ich habe alles ausgeführt, wie bei Ansicht Haken vor Konten/Ordnerliste. Das Problem besteht aber weiterhin. Ganz oben am Rand stehen bei Suchen die zwei Kästchen - STRG + K, die gehen aber nicht weg. Ich vermute, daß ich irgendwie eine falsche Tast angeklickt habe so daß die richtige Ansicht gehemmt wird. Es isr wahrscheinlich ganz was einfaches, ich weiß aber nicht wie und was tun. Hilfe wäre gut.

Hello My previous computer has crashed. C:/ is not available any more. In my previous computer, I had two hard drives: a C:/-drive (an SSD) where Windows and other software were installed, The second hard drive was a conventional drive (D:/) where I stored all my files, documents, images, and so on. On this d:/ I also had several programs installed including Thunderbird. On that previous computer, I saved and organized my emails into subfolders within Thunderbird.

Is it possible to recover my address book in Thunderbird? Is it possible to find/recover my saved emails? Could they perhaps be saved somewhere on my previous C: or D: drives?

I have an old copy of my C: and D: from 2025 I have also a complete copy of my D: from my old computer.

I have now bought a new computer and installed Thunderbird. I would be very grateful if this could be resolved. Kind regards Anders Quant
