I run message filters to file messages from Inbox in specific folders. However for some of my filters that copy or move a message to a folder in Local Folders the body of the message disappears, leaving only the message header. Other filters set up in the same way work fine. The filters are usually on the sender's e-mail address. Any ideas for a fix?

I am moving Thunderbird to a new PC, old was Win 10, new is Win 11. I installed Thunderbird on the new one, same version 115.10.2 though this is now 64 bit, old was 32 bit. I followed the instructions to move the profile by copying the Thunderbird folder onto aUSB stick then copying it to the new computer. The address book is there, but the local folders I had are not. Looking inFile explorer, I see that the Local Folders folder is there which contains all the folders I had, all populated, but there is also a Local Folders-1 there which does not, and this is the one Thunderbird is using. If I delete this folder, next time I start Thunderbird, it creates this folder again. I have obviously done something wrong, but cannot see what it is.

In the previous version, there was a search box on the toolbar. After the upgrade, it disappeared. How can I restore it?

I tried to customize toolbar but there is no search box in the window of available controls.

There is an email app provided by xiaomi on my phone.What in the email sent by this app contains a special format of `Date` fields.It looks like that: `Date: Thu, 2 May 2024 05:55:12 UTC` It doesn't look like others' `Date: Thu, 2 May 2024 06:05:15 +0000` or `Date: Thu, 2 May 2024 10:35:14 +0800 (CST)`

but it is still conforming to standards (or is it only parsable by the JavaScript Date method?)

After I modified windows time zone and restarted thunderbird. all emails changed time so this is not a time zone problem.

But this email shown two different times in the preview and detailed pages at this moment.

So can anyone tell me if this is a bug? Thank you.

Hello, in TB there is the option of displaying certain appointments or all appointments, e.g. in the next seven days (above the calendar). This also works perfectly on my Windows computer, but unfortunately not on my Linux computer (Ubuntu 22.04.4 LTS, TB 115.10.1 (64-bit)). In TB on Linux, no appointment is displayed as a list at all. What could be the reason for this? Thank you! Niels

Hi, starting with Thunderbird 126.b02 (al least) there are very heavy perfoming issues. Beyond crashes it takes approximatly 10 seconds to open a specific email. Moving to another account is much more difficult: taking itself a much of time it takes supplemental time to open the INBOX.

Despite an Raphael on-dice-graphics I'm running a discrete Radeon RX 6700XT. HDD is far away from being over-lastet or running out of memory

Any ideas? Appreciated. Thx. B.

Hello. Some time ago, empty folders appeared in the side panel of my account, I cannot delete them - how to delete them. Attached is an image with selected folders.

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.

The same happens in troubleshoot mode. I also tried reinstalling an older version but the same thing happens. Help me figure out what's wrong so I can read emails. :(

I notice this subject has been mentioned prior, but I cannot find a resolve. Been using Thunderbird for a long time without issues, but last week it stopped sending and receiving emails through the Skymesh internet provider. Still sends & receives Hotmail/Gmail/Yahoo, but will not connect to any Skymesh accounts. Have reinstalled/updated, but no change. SMTP timeout and if I change settings I get the 10060 error. Could not even connect to their Webmail page either. If I turn VPN on, then I can access their Webmail page. Rang Skymesh, they poked around and said it was all this end and with Thunderbird. Seems an IP number change via VPN with Opera resolved the Webmail page access, but I cannot do that thru Thunderbird. Running Win 7. Anyone ??

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.

Could not find anything in add-ons, settings, or about:config. There is a topic on this site https://support.mozilla.org/en-US/questions/1086884 but I am not able to follow it because there is no add-on or plugin to enable or I cannot find it.
