Hi grateful for any help with this please,

When I set the copies and folders setting to place a copy of all sent messages to my email address (IMAP server as i undersand it) it looks fine, but when I actaully send a message andthen look back at the setting it has changed to 'local folders' so the copy is only on the local laptop not accesible elswhere.

This isn't a problem wih an old version of Thunderbird: 102.13.1 (on an old laptop) but on 140.0.1 on a newer machine the problem is there...

Thanks John

My filters seem to work for emails received but not for ones I've sent. I use the rule "From, To, CC or BCC" combined with a persons email name (i.e. preceding the @ sign) and while From works the To doesn't and remain in my sent folder. Periodically I have to use "Run Filters on Folder" or "Run Now" from within the Sent folder to move everything to their respective folders. Do I have to have a separate rule just for "To"?

Greetings,

I recently updated to Thunderbird 140. After the update, I am unable to open .eml files by double clicking on them. I receive message window (attached image). If I do File->Open->SavedMessage I can successfully open the file. Please advise how I can get Thunderbird to open .eml files regardless of the instance of Thunderbird that originally created the file.

I shut down my computer on July 6th, went to bed, woke up on July 7th, opened my email to find all of my emails are gone. I had my daughter try and help and the app asked to set up an account. I (grandson) can find the profile and when I dig deeper in Mail I see 4 different inbox folders.

How do I get it to read the older inbox folders?

I have backed up the profile and deleted folder -3.net to try and get it to read the -2.net folder, it just recreates the -3.net folder and the emails only go back to 6/13/25. When I read the other .msf file in notepad I can see the archived emails dating back to 2020-2017. Even found the other folders that were under inbox.

I have a Suddenlink.net email account that I can't seem to install. Suddenlink has been purchased by Optimum. I have all the requirements that Optimum has given, but it still won't load. my email address is dluenser@suddenlink.net. My password is correct because I can go to their site and get my emails. These are the requirements that they gave me. Again, it is a suddenlink account. Can you help? I've tried numerous times to work with Optimum techs, but they are not knowledgeable to what I should do.

Recommended if your mail client supports) • Check My SMTP server requires authentication Username and Password (if needed) User Name: Your full email address, including the @domain.net at the end (i.e. @optimum.net, @suddenlink.net) Password: The password for your particular email address • Outgoing server verification/authentication must be enabled and on. If your email client has the option or checkbox that says My outgoing server requires authentication this will need to be checked along with use same settings as my incoming mail server.

I'm having an e-mail emergency, and will be very grateful for any assistance. Running TB 128.12.0esr (32-bit) on a 64-bit Win10 PC.

Earlier today, Thunderbird stopped sending or receiving via my main account, on an Earthlink-hosted domain that I own. Turned out that I can still send from accounts on two other domains, one a shared-hosting domain that I own; the other is Verizon/AOL. But I cannot seem to download from any of the three domains.

I checked all the SMTP and POP settings, which worked a few hours ago and have not changed. Restarted Thunderbird several times, inlcusing in safe mode, and rebooted the PC twice. Clicking "Get Messages" - globally or by account - does nothing. The thin blue "working" bar at lower right keeps scrolling, even if I press the Stop button.

I would prefer not to mess around with setting up new profiles and all. Can anyone here please suggest anything less complicated and risky that might get mail working again?

THANKS in advance!

We have Thunderbird set up to auto-connect to Plusnet's "Force9" emails, using a saved password, on a desktop machine running on Mint. It's always worked fine until today, when it gets to "Host contacted, sending log-in information"

then after a long pause a box pops up with,
"sending of password for user [ xxxx] did not succeed. "

It offers me the option of entering our password manually, which gets the same result.

If we log in on Firefox via their webmail portal, using the same password, it opens well enough, it's just much more clunky and slow to use than Thunderbird normally is.

Any advice will be welcome, please. Thanks.

My old Windows10 computer died, but I have an external backup with my Thunderbird profile folder. In the meantime, I have been able to resurrect an old Windows10 computer to continue receiving email, but was not successful transferring the backup profile. Thus, I have "new" profile on this second computer containing only the recent emails not in the backup profile.

I've purchased a new Windows11 computer. My question is: How can I merge my old emails in the backup profile with the recent emails received after the backup was made? In other words, is it possible to merge two separate profiles into one? Thanks.

Dragging and dropping a folder into another folder opens target folder. It shouldn't do that. The target folder should simply accept the folder being dragged into it and stay closed, as it always did since inception until a few versions ago. It is sooo annoying to always have the target folder fully expand when I have not desired it to do so! How can I prevent that from happening? Any help much appreciated.

I've got Windows 10 set up for a custom 'blank page' background color through a registry edit; I find a light gray-green much kinder on the eyes. This color came up just fine on a New Message (compose) page in Thunderbird until yesterday, but seems to have been broken by a Windows 10 Update yesterday (7/9/25) to Version 10.0.19045. My custom color still appears behind Microsoft system and app pages (Word & Excel), but no longer is the background for Thunderbird or Firefox, although it does appear behind address bars. Any ideas on why or how to fix would be most welcome.

But TB is ignoring it and even after unsubsubscribing and deleting the TB archive folder in Outlook, TB is recreating it after archiving the next e-mail. It also ignores the option to put all the mails in one folder and instead creates a one for each year. What can I do?

Hi,

I use Thunderbird as my e-mail client and have been saving e-mails from the inbox into a shared folder on my internal server for many years now. Normally, when I double click to open an e-mail saved into the shared folder, the e-mail will open in Thunderbird and I can click reply, forward, etc. However, since June 17, 2025, whenever I open these e-mails saved in the shared folder, only the subject of the email and two rows of menu bars (i.e., File, Edit, View, Get Messages, Write, Tag, etc.) appear, but the contents of the e-mail do not, including sender information. I've attached a screenshot so you can see what I mean (ignore the black background which I have set). Even though I can click "Messages" --> "Reply" in the menu bar, the composition window that pops up does not show any details of the e-mail I am responding to. However, if I transfer the e-mail file from the shared folder on the internal server to anywhere in my computer, say, the Desktop, the file will open normally in Thunderbird and display all contents normally. Would appreciate it if anyone could help me figure out how to solve this problem. My colleagues and I all need access to these e-mails saved in the shared folder so we can't keep saving them on to our computers. Thanks so much!

Older messages in Thunderbird are listed but their content is not showing. I have been using TB forever and I never had that problem before. It is POP3. When I try Folder Repair, the program simply throws out all messages whose content is not accessible (so if my Sent folder has 40,000 messages it comes back with a Sent folder of 2,000). Clearly something got corrupted but I am not sure what. In the picture below, the header is visible but (a) not clickable (different header showing) (b) no content is displayed. I used to copy the content of the TB folder to my laptop and back (while keeping different profile names assigned during installation. The problem seems to have started when I changed profile names and began using identical profile names on both the desktop and laptop. Also, the total size of the folders is around 65Gb, in case there is a size limit. Any ideas? Thanks

After wasting hours trying “this and that” – I did successfully "import" (not in the “import” menu) a single .EML (text) email file into my TB 115.10 e-client? I can’t remember how – and can’t duplicate it.

Yes, I know there’s an “extension” to do this, but if I did it only with TB 115.10 – why deal with the paranoia of permissions (must have access to everything)?

I need to “move” about 4000 emails from an ancient ISP (still used, too) into my TB 115.10 e-client – to then move to ”Folders” and then archive off-line. I can download emails (to my folder) from the ISP only individually as .EML files – and did get one successfully into TB (it reads [looks about the same] as an email “retrieved” by TB).

I can only “download” individual ISP emails (their rules, programming) so, hoping to set up a macro to “download” about 100 per day. My ISP inbox is almost full every day with new emails that must be deleted or “moved” due to new emails arriving every day.

Any ideas – or better still step by step suggestions?

Responses in Spanish are fine – French or Portuguese workable.
