Whatever button I click on, it goes into Set-up mode, though it's already set up on my PC, and getting out of the sequence is difficult, like navigating blind alleys to nowhere.

I get the following error when trying to delete emails:

Messages cannot be moved or copied because writing to the folder failed; to gain disk space, go to file, empty trash, then compact folders.

I have tried this and all trash folders are empty, yet the message remains, I cannot delete, move or receive emails. There are 970 emails in my inbox... I even rebooted several times after doing the above and it still does not work.

What ever instructional help is provided, please include how I can save some of those emails if possible as I don't want to loose them... Right now I have had to go to spectrum to be able to read any incoming emails. Thunderbird is bricked....

Please help...

Thank you

Hi all

I have my sent mail going into my Inbox be default, so that I can see entire threads in context. It's set that way in Copies & Folders in each of my email accounts. However, I frequently find sent emails in the Sent Mail folder.

Can anyone offer an idea of why, and how to fix it?

Trying to get a formal account with Thunderbird, and fully willing to pay for it. I have been locked out of using Thunderbird because I have never had a password for Thunderbird, starting from when it was Netscape. My only access to signing in and creating a formal Thunderbird account is a small laptop. Its screen is too small to show the entire form, so I cannot complete the captcha picture part -- can see three of probably four boxes (select all the traffic lights), and cannot see the 'Enter' or whatever is next.

On both MAC and PC versions. I recently installed a new SSL certificate on one of our company servers. It works on most email applications without issue (Apple Mail, Outlook etc.) - but Thunderbird is complaining about the certificate. The certificate is coming from: sectigo.com

The error is: unknown identity The certificate is not trusted because it hasn't been verified as issued by a trusted authority using a secure signature.

If I confirm the default exception - it uses port: 443 - instead of ports 995 and 465.

A certificate exception has to be deployed by adding network.security.ports.banned.override to the configure editor. Adding a string of 995 and then 465 to make the exceptions. It doesn't always work....

I have used multiple online scanners and they all give green lights on the certificate. Any help appreciated... I have no idea where to go from here.

Hello

Is there a way to have the TAB function in an email message body with an option to produce a string of dots, instead of just a blank space? I would particularly love to have it line up subsequent rows on the accounting decimal point when the $ sign is used.

EG with a list of expenditures:

Home Depot .....................$50.00 Office Depot ...................$200.00 Starbucks...........................$37.50

Hope this makes sense! thanks Baz

Hello,

Recently I have started to have emails fail to deliver to a certain domain and the message that comes back is

550 DKIM Sender Invalid - envelope rejected.

I am using Thunderbird v128.8.1 esr (64-bit). Extensions installed are: 1. Attachment Saver (Deimios, v.0.2.2) 2. FileLink provider for Send (Teal Dulcet v2.1.1) 3. Remove Duplicate Messages (Eyal Rozenberg v0.6.1)

I have been in communication with this client for several years and not had this problem before. When I send email to the same recipients using WebMail there is no problem, it is only when I send from Thunderbird.

I am not using any encryption type of setup.

Has anyone come across this before? Does anyone know of a solution?

Thanks, Franc.

Have just installed TB for the first time (replacing WLM) and am very happy with it. My only problem is that the option to open with a blank page is not working despite leaving the checkbox unchecked. I've tried checking and unchecking but it makes no difference, it always opens with the full setup options displayed. Is there another way to have TB open with a blank page?

Hi, Win 10 Pro new installation. Dell Optiplex MBR type Bios.

I had saved a recent profile to an external drive in its own name (i.e. not the profiles folder)

After the new Win 10 installation, I downloaded a new copy of Thunderbird.

I then copied the saved profile into the new Profiles folder, selected it in Choose user profile and started Thunderbird.

Thunderbird opened but not with the saved (8+ Gb) profile, just one new email account and asking for passwords to other email accounts I used before, and no folders.

I went back into the profiles folder and renamed all other profiles "OLDxxx999, but still the same one new email account when I opened Thunderbird.

I desperately need the saved email folders - I don't mind loading all the email accounts again, just need my court case history folders.

How can I force Thunderbird to use the saved profile, or can I identify and individually load in the saved local folders?

Thank you for any guidance towards a solution.

Hi,

I'm experiencing issues with threaded view in Thunderbird (version 139.0.2 on Windows). Some threads do not display all messages -only a few emails are shown (e.g. 2 out of 8), and others are missing from the thread view even though they are present on the server. Rightclicking a message and selecting "Open message in new tab" sometimes works (but still doesn't show all messages), and sometimes it doesn't open a new tab at all. the missing messages do exist on the server, and I can find them using Ctrl + Shift + F , but they do not show up in the thread, nor do they appear via Global Search, even though the global index has finished building.

I have tried the following: -Right-click folder > Properties > Repair folder -Deleted and rebuilt global-messages-db.sqlite (global search database) -Reduced IMAP mailbox size from 140GB to 110GB -Waited for reindexing to complete

But the problem persists. It seems that Thunderbird either doesn’t associate all related messages with the same thread, or skips them entirely in display and search.

What can i do to fix it? Thanks in advance

For >20 years I have used Thunderbird as my email reader for various email accounts on my mac laptop. Last night Thunderbird stopped downloading emails from my yale.edu account. I tried removing the yale account and reinstalling it unsuccessfully. See attachment. The Yale IT rep told me that Yale very recently added security features that are probably preventing Thunderbird from working with it. They told me to use the Outlook app. Is there anyway I can get Thunderbird to work with my yale.edu outlook email account?

I use Thunderbird for several yahoo email addresses that I have. Yesterday the one account wasn't transferring over from yahoo so I deleted it and then reinitiated it (POP server setting). I've done this before with another email address I have and it worked, but things must have been set up differently this time as it no longer showed any of my older emails (apparently only showed what was still present at Yahoo's site). My understanding is that my old emails would still be saved on my computer (Windows 10), and I went through the steps on Thunderbird to get to where the stuff is on my computer but when I open any of what appear to be the stored emails, everything is coded in such a way that it's near impossible to read. I'm hoping I can somehow transfer them back to Thunderbird somewhere or, if not, open the file so I can at least read them easily. The Local Folders file that's currently on Thunderbird for some reason has stuff from another email address I have (I believe that one is imap and not POP). I'm very uncomputer savvy, so any help I can get would be greatly appreciated so I don't mess things up more. Thank you

The inbox on my default email account (cfgait@gmail.com) was showing that I have new messages. The total was not highlighted in its usual blue but since I'm colorblind, I can't tell you what the color is. Obviously, something is out of sync. The mail tool thinks I have new messages (which, in fact I did because I checked them using the Chrome browser) but the mail tool could not or would not display them. This seems to have started happening ever since I downloaded the latest 128.12.0esr (64-bit) release (esr). I deleted my account and added it back in. Unfortunately, I also lost all of my email rules. What can I do to recover?
