Forum Bashkësie Thunderbird

Since setting up Yahoo email on TB using POP3 setting, I noticed that while all my Inbox messages remain when downloaded on my PC, the Sent messages are being gradually deleted to leave only the most recent (currently) 11 messages, like it is if I log in online to Yahoo webmail. Does this mean I need to configure it to IMAP as well to make sure nothing is deleted once downloaded to TB on my PC?

Hi I have successfully linked my TB Calendar to Nextcloud. However, Tasks are not syncing.

When I go to create a task in the shared calendar TB advises: Please select a calendar that supports tasks

I understand later versions of TB now handle CAL and CARD Dav better.

Some have suggested using TBSync addon, however that appears to only support account creation for Google and MS calendars, but not Nextcloud.

Is there a setting in TB or NextCloud I am missing, or an addon ???

Any thoughts appreciated. Thanks

On 6th Feb 2026 a professional set up Thunderbird [149 I think] on my Desk top computer, running Windows 10, with 2 email addresses. Last week I found I could receive emails on both, but not send on either. I know the passwords for both the addresses, but even if I put them in when asked, I still could not send. Then I found I was not receiving e mails on either address as well. I am 87 and may have changed something important, in an effort to find a solution, as last Friday [27th March] thunderbird crashed. I sent the report to thunderbird. Yesterday I received the previous day's emails and current ones. Today [29th] I am receiving, but not able to send again, My email default is set as Thunderbird. For many years I was with Plusnet, but recently I had to transfer to Greenby. I checked their Web mail when I was not receiving emails and they were on their Server. I can make simple changes in Account Settings eg Port, Outgoing Server, Security.. Is there a simple solution or should I call the Professional again? Thank you.

I store many e.mails in a variety of Folders. Most are viewable but at least one folder (ATTIVO) says there are no e.mails despite having just saved them there. These e.mails are visible via my i-phone. As I have passwords etc saved on my lap-top this issue is problematical but not fatal but does indicate a glitch in Thunderbird that makes me suspect it's general reliability

When I select Thunderbird email it responds very slow. When I select a message, the message does not show up. My email is carolinascene.com and my hosting company is AIT. Advance Internet Technology. What can I do? Call me because I do not get email. [edited phone# from public community support forum] anytime. Thanks! Gerald Robinson I have donated and will again!!

The University of Minnesota makes me change my password for their email IMAP server every year. I use Thunderbird as my email client. I have not had problems in the past, but this time Thunderbird does not connect with the UofM server and I cannot update Thunderbird with my new password. When Thunderbird tries to connect, I get a Google "help" message about clearing my Chrome cache that does nothing. I deleted the old IMAP password in Thunderbird, but that did no good. Is there a way to update my credentials within Thunderbird?

Thunderbird will not get my mail. It continues to send mail but will not fetch it,

I tried to delete the account in thunderbird, It will not reestablish the account. I can use a web login to get to my email on the server but the identical credentials will not establish the account in thunderbird, I can establish an account in Outlook but not thinderbird.

We have an email account that is gmail behind the scenes but uses a front end alias (e.g. name@organisation.ca). Adding the email account to Thunderbird is no problem, TB recognizes that it is a gmail account. However, it does not automatically add the address book. I tried to add manually using the new Accounts Hub CardDav putting in the email address under UserName and putting in imap.gmail.com:993 for the URL/Hostname. It does not work and I get the error: Component returned failure code: 0x80004002 (NS_NOINTERFACE) [nsISupports.QueryInterface]

For the last couple of weeks I have been having trouble connecting to gmx.com. It keeps saying connection to server imap.gmx.com timed out. I deleted and reinstalled the account but same thing. I also contacted gmx but so far no response. Is there something I am missing in the settings? Is anyone else having this problem? Thank you

Nie mogę wysłąć wiadomości. Przy póbie wyslania odpowiedzi na otrzyany e-mail wyświetla się taki komunikat

ich habe ein outlook konto, dass ich mit thunderbird öffne. vorhin habe ich neue ordner erstellt, bei thudnerbird, und dort emails reinkopiert. die sind allerdings dort nicht angekommen. ich habe dann thunderbird geschlossen und outlook online geöffnet. die ordner sind da, die emails aber nicht. sie sind auch nicht im gelöscht ordner oder in einem anderen ordner, sie sind einfach weg. was kann ich jetzt machen

When I try to send an email, Thunderbird says failed and asks for the outbound.att.net password. I've entered the correct password and the send fails again.

This started happening about a month ago, without me changing my settings, which are to retain all emails unless manually deleted. Probably relatedly, copies of sent emails are not saved in the Sent folder. This is my account on yahoo.co.uk - all the emails are available when I go to yahoo through my browser, so it is just Thunderbird that is not ertaining them. I automatically accept Thuderbird software updates (now 148.0.1)

Hey all, I installed the current version of Tbird on a couple of machines for a friend, one machine worked fine for a month or so, then started giving the "unable to write the email to the mailbox, make sure the file system allows you write privileges, and you have enough disk space to copy the mailbox" error. There is a ton of free space on his C: drive, hundreds of GB. Yesterday I installed Thunderbird to another of his PCs, also no 3rd party AV (both running Win 11), same exact error after downloading a handful of emails from a few weeks ago. To make things weirder he took his laptop (the machine that worked ok for a short time) to his office, where he has a different ISP and it downloaded all of his mail! What is going on here? I have seen plenty of threads about this error, I tried compacting, repairing the folder etc, nothing fixes the problem and Thunderbird sits there not syncing his mail. At the bottom of the window it shows that there are 200 or so emails to download, it looks like they are downloading for a bit, then it quits trying and gives the error. Is there a known cause of this seemingly common error? Are Thunderbird devs aware there's an issue that renders their software unuseable for some users? His mail account is with Brightspeed, an old centurytel.net account. Please share any tips you may have for overcoming this error, thanks!

Starting with Thunderbird 149, the Find command (Ctrl+F) no longer reports the number of matches; nor which match you're on, like "3 of 8 matches". I really miss that feature; please bring it back.

The Braille Institute has developed fonts that are 'hyperlegible'. How do i make "Atkinson Hyperlegible Next" the default font for headings, toolbars, message list, etc?

I can be found at https://www.brailleinstitute.org/freefont/

I am moving from a win7 pc to a win11 pc. I have exported from my win7 pc fine and get a zip file of 6.6gig. I moved it to the win11 pc, where I have installed Thunderbird.

On the win11 pc I go to tools, import and it chose the import all option and press next. On the next screen there is a live button at the bottom that says next but when I press it I get nothing.

Any ideas most welcome, thanks in advance.
