Is Thunderbird not compatible with Earthlink email? I can't seem to get my account added. All of the information is directly from my earthlink account set up information but I just get messages saying the configuration is wrong or password etc. I have checked and rechecked, reset the password multiple times so it is definitely the right password yet it fails to connect. if it simply can't be added I get it and will move on but I have no issue setting it up to other accounts so I just want to be sure I am doing it right and that it is in fact compatible. thanks for any help.

Recently, I have experienced an erroneous browser launch, simply by clicking on the title of the message in the list pane. This problem seems to occur when clicking on emails from a particular UK supermarket (tesco.com) and the web page opened has a long and complicated URL, but the page contains only a single pixel which shows up as a white dot on a black background.

Obviously, it is likely that there is something strange about that source, but the problem doesn't occur if I click on the same email in a different email client (in this case Evolution).

I have tried various Settings as advised by web searches and also the solutions suggested in Thunderbird Help (Troubleshooting Mode and Troubleshooting Information).

I am running Thunderbird 140.5.0esr (64-bit) on Kubuntu Linux 24.04.

How do you look down through your emails and select multiples to delete? the answers I've found involve highlighting and deleting a bunch in a row. What about when there are a couple of keepers in the mix?

I can see that there has been a reply or a messages was forwarded and when I right click for the menu "Open" may not even appear at times. When it does appear "Open in Conversation" is not always presented as an option even though there has clearly been conversation as I can locate reply's in the Sent folder. Sometimes it's there but when selected it opens a tab that only shows the email and none of the conversations. It's hit and miss and I can find no rhyme or reason. Any help would be greatly appreciated. Also, I would love to Testflight Thunderbird on Apple. Thanks, Sue

SIMPLIFY THUNDERBIRD IT IS EXCESSIVLY COMPLEX. I CANNOT EVEN SEE HOW TO MOVE MESSAGES FROM THE INBOX TO THE RELEVANT FOLDER IN MY LIST. I PERSONALLY BELIEVE FIREFOX AND THUNDERBIRD ARE OVERCOMPLEX AND NEED SIMPLIFIED. SIMPLES. WHY CANT I COPY AND PASTE THE VERSION NUMBER. BLOODY ARESHOLES . AS I SAID IT IS BLOODY OVERCOMPLEX. AT THIS POINT I AM CONSIDERING GIVING UP ON WHAT IS CLEARLY AN OVERCOMPLEX PIECE OF SOFTWARE THAT REALLY DOESN'T LOOK GOOD EITHER AND THERE IS NO OFFICIAL SUPPORT SO WILL HAVE TO LOOK FOR AN ALTERNATIVE. COMPLETE WASTE OF SPACE TOO MANY COOKS SPOIL THE BROTH COMES TO MIND THIS IS WHAT WE HAVE HERE

I keep my mail (both sent and received) in local mail folders. My server is gmail, and sent mail is put in gmail's sent folder by default. Every few months, I copy those messages to a local folder, and after I back them up, I delete the server copy.

What to my dismay, I discovered today that only the message headers, and not the messages were present in the local folder, though they had been when downloaded. Looking at the file sizes, I found the sent file to be 0 Kb, and sent.msf 255 Kb, when sent should have been around 60 Kb long.

I have been able to restore the messages from backup (whew!), but I have no idea how then sent file was wiped out. I know I did not do it.

Has anyone else had this happen? Is there a preventive measure I should take?

I have just transferred my website to crazy domains and in order to set up email they need DNS records for thunderbird. I dont know how to access this. Could you please provide these for me.

bold texti had a folder for emails for personal saved emails and i went to thunderbird email and it was gone i have checked my profile and that folder does not exist. i checked my yahoo mail file and that folder does not exist

I successfully set up three of my Google Gmail addresses on Thunderbird. I tried to set up my fourth and primary Email address, which is on a Spectrum server, using the absolutely correct address, user name, and PW. Thunderbird will not accept it, saying there is an "authentication error", but not identifying what it is. How is it possible to fix an error, if no precise error is specified? Thanks for any help anybody can offer.

Hi,

My mail account was recently migrated to office365, and I saw that Thunderbird v145 and later supports this natively without the use of a plugin.

However when I follow the instructions to set this up I don't see the Account hub in the same way that's shown in the article.

https://blog.thunderbird.net/2025/11/thunderbird-adds-native-microsoft-exchange-email-support/

instead I see the one attached.

I've tried this on both Linux (ubuntu 24.04) and Window 11 both with my original profile and a completely blank installation. On Linux I've used both the Canonical supplied Snap (from the monthly/stable channel) and the download directly from thunderbird.net.

Any help appreciated.

There is a message in my Inbox that cannot be deleted or moved. I've tried re-starting Firefox several times to no avail.

The stubborn message is actually completely blank when viewed in Tbird. Also - the stubborn message has already been moved to another folder where it can be read (i.e. message contents available). Yet - this stubborn "ghost" mail message will not disappear from my Inbox!?

I am connected to an Exchange email server - one of the "shared" servers administered by Microsoft.

I had hoped to get away from the insanity of Outlook, but it seems when it comes to email, there is no escape!

And finally FWIW, When I view my Inbox in "Web Outlook", there is no "stubborn ghost message" in the Inbox - the message is where I moved it.

A few days ago I lost all of my saved email messages, plus "sent" emails, and "deleted" emails. I had important information stored there for future use. I am hoping to be able to retrieve it. Any help would be appreciated. Thank you!

Two identical spam emails came in, and I deleted both from my Inbox. Both had attachments. Deleting them moved them to the Trash folder. When I went to the Trash folder, I found both emails had been combined into one file. Is that "threading"? I don't want any emails to be combined together EVER. Previously I had checked the "Unthreaded" box in Settings; so if this was threading, why did it happen?

Another question: I couldn't find anything to do with this combined file but to delete it. Did the act of deleting it also delete the attachments, which probably contained viruses?

This "threading" business has been going on for years now. I always check the options that supposedly disable it, but then it keeps happening.

I am trying to add an email address to thunderbird it is an outlook email address [edited]@outlook.com I have checked the address and the password and both are correct however thunderbird says that the configuration is incorrect and will not accept it. also I have it open in another browser window will that cause problems ?

I am using Mail Merge to send messages, and want to have the date in the body of the message change to the date I actually send the email. Or I have a draft email that I eventually send. Is there a field that will insert today's date (to compensate for me forgetting to change the date manually)?

Unable to add personal Hotmail/Outlook.com account via IMAP with OAuth2 Hi, I'm unable to add my personal Microsoft account (@hotmail.com) to Thunderbird via IMAP despite trying every solution I could find. My setup:

Thunderbird (latest version), macOS Sequoia 15.6.1 Account: personal @hotmail.com

What I have tried:

Manual IMAP configuration with both smtp-mail.outlook.com and smtp.outlook.com as outgoing server OAuth2 authentication — the Microsoft login window opens, I successfully log in, but Thunderbird still throws "Unable to log in at server" Enabled cookies for all Microsoft domains (outlook.com, login.live.com, login.microsoftonline.com) in Privacy & Security settings Enabled 2FA on my Microsoft account and generated an App Password, then tried with Normal password authentication — same error Toggled the experimental Account Hub off and on, tried both the new and old account creation flows Restarted Thunderbird multiple times between attempts

What works: My institutional Microsoft 365 account (@hnu.de) connects and syncs perfectly with identical IMAP/OAuth2 settings. The issue appears to be specific to personal Hotmail/Outlook.com accounts. Has anyone successfully connected a personal Hotmail account recently? Any help is appreciated.

I use Thunderbird to store loacally some email from gmail and delete it from the online server.

Until october last year it was working flawless, to day I need to read an old email and I discovered that locally since october of some email is only stored the subject and somtime I only have the ticker that increase in the stored email email, but there is either not title or subject. I didn't change any setting in my computer or in the antivirus,, the only thing is that I perform the update of thunderbird as usual. Is it possible to recover these emails or they are gone forever?

Best regards
