Diễn đàn hỗ trợ Thunderbird

Hallo, ich habe vorgestern ein neues Win11 aufgesetzt und dann die neueste Version von Thunderbird installiert. Mir ist jetzt aufgefallen das sich die E-Mails nur mit einem Doppelklick öffnen lassen und das dafür ein neues Fenster aufgeht. Früher waren die Mails mit einem Klick zu öffnen und der Inhalt wurde auch direkt unter der Mail angezeigt . In den Einstellung steht der Doppelklick nicht in der Auswahl sondern als einzige Möglichkeit. Gibt es da irgendeine Möglichkeit um das anders einzustellen, einfacher Klick und direktes anzeigen ohne extra Fenster? MfG

Hello, the day before yesterday I set up a new Win11 and then installed the latest version of Thunderbird. I have now noticed that emails can only be opened with a double click and that this opens a new window. Previously, emails could be opened with a single click and the content was also displayed directly below the email. In the settings, double click is not in the selection but is the only option. Is there any way to set it differently, single click and direct display without an extra window? Best regards

Subject: Persistent Column and Folder Layout Issues — Not Being Saved Between Sessions

This is a follow-up to my previous support requests regarding two ongoing problems that significantly impact daily usability.

Column Settings I manage multiple accounts, and my preferred column layout is: Starred, Read Status, Attachment, Subject, From, and Date/Time. I do not use Threads, Correspondents, or Spam Status columns. Despite setting these preferences repeatedly, Thunderbird fails to retain them. Every day I must spend time reconfiguring columns across some or all of my accounts — the state varies unpredictably from one session to the next. This is a persistent, daily frustration that costs meaningful time. Most other major email clients save and reliably maintain column preferences. I'd expect Thunderbird to do the same.

Folder Panel Layout Two problems occur regularly when Thunderbird loads:

Folder order — Standard system folders (Inbox, Sent, Drafts, All Mail, Trash, Spam) should appear at the top of each account. Instead, Sent, All Mail, Trash, and/or Spam are frequently scattered among custom folders, with no apparent consistency.

Folder expansion — Most or all folders load in an expanded state, exposing every nested sub-folder regardless of whether they contain unread mail. This creates unnecessary visual clutter and requires manual collapsing each session.

Again, this behavior is uncommon in other widely-used email clients. Summary These are not one-time glitches — they recur daily and represent a significant usability gap. I'd appreciate confirmation that these are known issues being tracked, or guidance on a reliable fix. Reformatting the interface every morning is not a reasonable expectation for users.

In event creation in Calendar the options for repeat pattern are daily, weekly, bi-weekly, monthly or yearly. There is an option to create a custom pattern, but if I enter every 28 days, because I want the event to recur every four weeks, it is over-ridden by the option above which is the repeat pattern, daily, weekly etc and the event appears daily. There appears to be no way to create an event that occurs repeatedly every four weeks (28days)?

Can anyone help please?

I've been using Thunderbird on Windows 10 since last year sometime. Currently I'm on version 151.0.1.

I've 4 x mailboxes here and since yesterday, 3 of them show me an unusual message when checking for emails. I tried attaching a screenshot but although the screenshot uploaded, I couldn't find a way to insert it here. But the message says Unable to write the email to the mailbox and asks me to check if I've write privileges (which I have) and to cheek the available disk space.(currently 101GB free).

The message is happening 2 or 3 times each day and lasts for about half an hour, then everything works fine again. Has anyone else seen this??

The newest version of Thunderbird wiped out the stored files from the previous version by making me create a new identity. I have tried several times to use "import" to retrieve backed up data from the old version, but without success, even after I re-installed an earlier version of Thunderbird. Each time I use the "import" feature I get a message that it failed unexpectedly. I need these old e-mails because they contain receipts for charitable donations that I need because my tax returns are being audited. What can I do?

I use Thunderbird on dark mode, so by default, unformatted text (where I haven't explicitly set text color) appears as white text on a black background in my compose window. The same unformatted text, when sent to someone viewing it in light mode, appears as black on white to them and remains readable. When I use white text in my compose window, it looks identical to me, but remains white when sent and is thus unreadable white-on-white to those using light mode. Is there something in the composition window that indicates whether I'm typing with formatted or unformatted text? (No, the color selector tool does not do this. When typing unformatted text, it displays the last selected colors, regardless of whether they are being used.)

If there's no way to distinguish this, could someone please add a UI element for it?

Can't download messages on one of my computers. Account icons show locked, I think. See attached file. Downloads were working but now can't download anything newer than 01 June. How can I "unlock" the accounts? All my other computers are downloading messages just fine.

I've been a Thunderbird user for years without problem. However, since May 22, three specific messages continually reappear after deleting them from my Inbox.

I keep my Inbox empty and it stays that way, except for these 3 messages. Removing them from the Trash folder has not solved the problem.

My email provider is netaddress.com via POP3 account. I signed on to look at my inbox on their site via a browser, and the messages aren't there.

I have tried repairing and compacting the inbox, but the messages continue t reappear.

Do you have any other suggestions?

TIA.

Hello,

Everything working just fine last night. Wake up and Thunderbird will not retrieve emails.

Remembered this old message I got so I went through and deleted my second email address, didn't help.

https://support.mozilla.org/en-US/kb/thunderbird-and-yahoo

Checked all settings compared to Yahoo, still won't download messages. I can even send a message with my current settings no problem, and it does login, just won't retrieve emails. Gives me a connection timeout.

Anyone have any ideas?

One emails will not download from server. Using the repair folder it says folder is busy wait until finish. All other emails work fine. One email only keeps going back. Thankyou

After a recent update to Thunderbird (months ago), I found that when I search through my emails by name, it will find those emails and list them for me. But when I go and click on one of those found emails, it arbitrarily brings up some unrelated email - it never brings up the one that I click on.

How can we fix this? Thanks. Dr. Howard Neufeld

I have used Thunderbird (Windows 11 PC) as my email application with my Road Runner / Time Warner / Spectrum email account for over 20 years. As recently as a week ago I could send emails. Now sending fails with this message - "Sending of the message failed. The message could not be sent because the connection to Outgoing server (SMTP) mail.twc.com timed out. Try again.". No problem receiving emails in Thunderbird. I can send emails if I log into Spectrum.net in a browser and I can send emails from my Android phone. All server settings did not change and match those that the Spectrum web site says to use. Thunderbird is up to date - 140.11.1esr (64-bit). Windows is also up to date. Spectrum tech support was no help. Thanks

I setup an address book for a club so I can send BCC emails but it won't use the club address book! I had one in my old computer. So I try to send an email, click BCC and start typing the club name and it doesn't appear! In my previous computer it would find the club address book and insert it in the BCC line! This new one doesn't do that!

Can't get email from Comcast server any more & a lot of existing emails disappeared. Was on the phone with them & reset ports & checked other things but it didn't work. I can read them at Comcast's site & also send & get them there. Also can you help me forward my email to another email program?

I accidentally deleted a good number of my emails from my local Pop3 server account. I don't delete my emails from my gmail server so I can just redownload all my emails but cannot remember the prefix needed to do it.

If I recall correctly I go under settings for my email account, then go to server settings and add the prefix to my email shown in the Username field under the Pop Mail Server Section.

Can anyone remind me of the prefix?

It was like restore:[my email] or all:[my email].

I should have made a note of it as I cannot find it anywhere online now.

Why are many calendar events just disappearing? This has been happening for the last three months!! Calendar events were there yesterday, are gone today! I tried in protected mode and lost even more events. Now even more are missing. Several I have re-input over the last months, and they get gone too. What’s going on!! There are no addons, no sync. Nothing but Thunderbird. any one else having this bug?? What file are events stored in and how do I read them?? Any way to recover anyof these?? There is a lot of information and annotations, such as cancellations and rescheduleing and the whole bunch just disappeared? Many older events are still intact but I sure don't know for how long!!! My profile is on a separate drive and is accesed by both W10 and 11 for email and calendar. No problems except they are missing using either system!! It's a bug!! Anyone interested in looking at it??
