Thunderbird Support Forum

When I create a task in Thunderbird I can use the formatting options, like a changing the font to bold or add a bullet or numbered list. After saving the task all this formatting somehow completely disappears. How to solve this?

When trying to configure my gmx.com email with Thunderbird I get this message when trying to create a new account.

Component returned failure code: 0x80004005 ▲ (NS_ERROR_FAILURE) [nsIMsgAccountManager.createIncomingServer]

I have set the email up many times before just never with Thunderbird on a Linux setup so I am not too sure what would be causing this, trying to find help for this I come across the same issue with varying differences. At first I thought it maybe my firewall but I disabled it and tried again and still same error. Any help much appreciated.

I renamed a folder and now the folder is not showing. As the folders contains few emails and I want to those back, tried restarting the thunderbird many times. Let me know if faced the same before and found a solution for it.

unable to send email. error messages is Sending of the message failed. The message was not sent due to exceeding the allowed number of recipients. The server responded: STARTTLS is required to send mail [MW4PR03CA0086.namprd03.prod.outlook.com 2024-05-13T23:07:11.907Z 08DC72A03191847E].

For the past few weeks I have not been able to open attachments (Photos and PDF file) to emails received from a variety of senders. If I use different mail service programs, they work fine! WHAT IS WRONG WITH THUNDERBIRD????????

Hi there,

I have Thunderbird 115.10.2 (64 bit) on my Macbook Pro running OS High Sierra 10.13.6.

The "Sent" list of folders is missing one of my Email address folders. But further down the folders column, there are folders with lock icons and the 'Sent' folder is visible in Email address in question's folder (photo attached). Similarly, the "Drafts" folder is missing the Email address's drafts folder.

I've tried the following to fix the "Sent" folder problem:

1) Account Settings -> Copies and Folders -> checked "Place a copy in:" -> "Other" -> [correctly selected address here in dropdown menu] -> Sent. Then I quit and restarted TB. Nothing happened, and the folder did not show up in the list.

2) I tried changing the Security Settings from SSL/TLS to STARTTLS, then restarted TB. That did not fix the problem.

I haven't tried fixing the 'Drafts' folder yet, but I hope you are able to help me restore the missing folders.

Thank you in advance.

I have created a filter to forward and email as soon as the message comes in. I does not do the auto-forwarding but will do if I click Run now.

I had to reinstall TB due to the fact that for years my mail server was Cox who recently decided to get out of email business and transferred all my messages to Yahoo. The transition has not been going smoothly. Image attached.

I've been using T-Bird for about 15 years, or more. On May 8th it stopped working - unable to receive or send e-mail. I'm using T-Bird 115.10.2 (64-bit) and I've been running Windows 7 Home Premium 64-bit since 2012, and have no intention of upgrading to a new OS. If I do upgrade to a new OS, it will probably be the latest Mint Linux, as I installed an earlier version of Mint a few years ago to check it out as an alternative to Windows.

I have a 3.2GB AMD CPU and 16 GB RAM. Luckily I can access & use my AT&T Mail at currently.com, but I like T-Bird a lot better. T-Bird has essentially worked flawlessly for me all of these years - until now.

I have re-set my AT&T Mail password 2 times and also tried my AT&T Mail's "Secure Mail Key" from 2020, which is supposed to "never expire" - to no avail! T-Bird does not like any of these Passwords.

So it appears to me that T-Bird is now dead.

And so I am looking around for the best new e-mail client to use.

I am reluctant to try uninstalling T-Bird and re-installing it, out of fear that I'll lose all of my T-Bird data (folders, files, settings, etc.).

Also, I just found a recent article that claims that T-Bird will no longer work with Windows 7 after "late 2024." So I wonder, if the Thunderbird team has already euthanized T-Bird.

I shall greatly appreciate it if you can help bring my T-Bird back to life.

Thank you very much!

My email server changed recently from one IMAP server to another. Since the change, Thunderbird keeps marking some messages as Unread. Often these are old messages, reveived weeks or months ago and definitely have been read. The process appears to be random: I laboriously work through multiple folders, marking them as Folder Read. Only to find, next time I open Thunderbird, that there is a new set of messages and folders flagged as Unread. In Settings I have 'Automatically mark messages as read - Immediately on display' checked, which is the desired and normal behaviour. I'm stumped!

Hi folks

When viewing some [not 'all'] PDFs I've created via T'bird's inbult PDF preview on my W10 Desktop PC an annoying black blob in the shape of a car key now appears on the PDF's pages from page 2 onwards. When viewing the same file via an iOS device or inside Dropbox there is no black blob. Also, when viewing the same file via the full Adobe Acrobat APP on my W10 Desktop PC there is no black blob. This black key-shape blob only shows inside T'bird's inbuilt PDF previewer.

I know how to change the preview function inside Tbird to instead open any PDF in Acrobat, but as I quite like the T'bird PDF preview feature does anyone know why these black keys are appearing and how to get rid of them?

Further info: The only PDFs with the black blobs are those created via my W10 Desktop PC's PowerPoint APP's "Save as Adobe PDF" function. There is no such black blob on the PowerPoint pages themselves, and again no blobs appear when viewing the new PDF on any iOS device or within Dropbox. Additonally, and since writing the above lines, I have emailed the PDF to a friend who has opened it on his W10 Laptop and there are NO [again, NONE] black blobs on his screen [he uses Outlook as his email handler]. Thus, I feel certain the problem is within T'bird's PDF preview code.

Is there any fix for this?

Thanks.

Somehow, the "auto-BCC" feature in one of my Thunderbird accounts has been activated. How can I disable that? When I open an email now (in my 'in-box'), it automatically fills in "To" and "From" fields. I no longer get my 'in-message' toolbar in the upper right-hand corner of the message window (tab). I also no longer get the notification that "Thunderbird has blocked remote content..." How can I restore this without deleting and rebuilding the account? I'm sure this was mistakenly activated but it needs to go away!!!

On a further note, I have found that if I move a message from my in-box to ANY other folder, I get the normal message view, with all the correct toolbars and indications and controls! Attached are the correct and incorrect screenshot of the same message, just in different folders.

Thanks in advance for any help that anyone can provide.

I am trying to add a secondary Comcast email account to T-Bird. The primary account was added OK. This is a sub account of the top one.

Note, I have 2 other computers and I was able to add this sub account easily, but that was some years ago.

When I go through the motions of adding my email address and password, when I click "Done" a window pops up with the massage "Secure Connection Failed" The error code is PR_CONNECT_RESET_ERROR.

When setting up the primary account, the little window asked me my password then asked if it was OK for T-Bird to access the account. This was as normal like all the Gmail ones I did.

But it seems this sub account cannot be added.

Any Ideas?

Thanks, Mark.

When I click on the arrow to acquire any emails from my isp it will often say downloading 3 emails or 5 emails or some number, but only one or two come in. I have to hit the arrow again to get more. Sometimes it will say downloading some number of emails, but NOTHING comes in. I don't remember this happening until about a month ago. Can you help?

Quite often I find that Thunderbird is very slow to obtain a connection with my Outlook account. I can run my Outlook directly and everything is updated in about 20 seconds and at the same time it may take a couple of minutes up to a few minutes for Thunderbird to complete downloading. Additionally, many times during this lag in connecting, I receive a message that the password is incorrect, which is bogus; all I have to do is select "Retry" and the download process continues. I am using the latest version of Thunderbird "115.10.2 (64-bit)." This problem has been occurring on previous versions as well.

My email was converted from Cox to Yahoo by Yahoo on a system wide conversion on April 27th. In the transition I lost all the emails in my Thunderbird inbox from 4/12 back to the first of the year. I also lost everything in my draft folder.

Carbonite did a restore of the default file (that was dated 4/8) by couldn't get these back. Need to get everything that was in the inbox and draft file on 4/26 (or sometime prior) What can I do?

When I try to open and email link, it immediately starts to download Firefox Installer. It is already downloaded and up-to-date. This has been going on now for almost a year. Please help me.
