Help setting up first email account (protonmail.com) Keep getting: "unable to login at server, ether config, or credentials" error.

New user - I recently moved thousands of messages from my inbox to a local folder.

At some point, Thunderbird asked me to compact folders and I said yes. I noticed today that I am now missing about 13 years worth of messages from my local inbox folder.

Since I moved them, it deleted the messages out of the original inbox (I also logged into that account via the web and they are not located in the trash on the server either). There are now only a handful of messages there.

Does compacting mean that messages are deleted? Everything else I read said specifically that it would NOT delete messages. Any tips on how I can recover some really important messages? (It deleted about 13 years worth of messages from early May 2026 back to mid-2013, so there are recent messages in there I really need!).

Steps already taken: I tried using "repair folder" and that did not work. I do not have any automatic filters set up. I tried locating my Profile, and moved the "msf" files to my recycling bin, as I read that deleting the msf file would rebuild the index and display emails that had disappeared. Nothing changed. This was new for me so perhaps I did something wrong? I haven't emptied the recycling bin yet so the files are easily retrievable if necessary.

Trying to setup Thunderbird for wife’s new laptop… Her 4 separate email accounts with auto setup for the IMAP server info without issues. One account however will not – VERY frustrating as this works fine on her old laptop. Thunderbird setup now appears to have an extra (4th) field required when setting up the account: Usually, its just name, email address and password. I see there’s now an extra box titled ‘Your Login’ being required for auto login. I have no idea what this field should be set to. Also, when I attempt to do a manual setup for the account, the port numbers and server names shown on the internet are completely different to those used on auto, and still get rejected. Doesn’t help that MS trying (and succeeding) to confuse us with all this “Outlook vs Outlook Classic vs Outlook.com”. My wife is unable to continue her work until I get this sorted:-( PLEEEAAASE can someone help me setup this xxxxxxx@outlook.com email account in Thunderbird as an IMAP account?

I was cleaning up my Inbox when I looked at the "Important" folder. I read in a number of places that this is a "Gmail" thing, and messages get in this folder apart from any action etc on my part.

I have a couple questions.

FIRST, are the emails in the "Important" folder only in that folder or are copies in there? I deleted a number of 2 to 3 year old emails that I do not consider important today. The closer I get to this year [2025], the more careful I get.

SECOND, how can the auto-population of that folder be stopped and the folder be deleted? I keep my important emails in designated folders so I can find them.

Thanks in advance

Hi - I can't seem to delete from my Yahoo Mail via Thunderbird.

With Yahoo's new mailbox limits I wanted to clean up my Yahoo mail box and Yahoo obviously does not provide any decent tools to support search and delete.

I downloaded Thunderbird and despite several deletion attempts my Yahoo mailbox still shows 160,000 emails whilst my Thunderbird client only 9,000 - so when I delete it is not syncing.

Most emails are deleted from Thunderbird however some are now reappearing (in Thunderbird). No deletions from Thunderbird are reachign my Yahoo mail inbox, however I can send emails from Thunderbird and see the sent and received email in Yahoo and I can add folders in Thunderbird and see those folders in Yahoo.

I tried several things

- immeadiate delete in Thunderbird - moving the emails to a folder in Thunderbird and then deleting from that and then deleting the the folder - I check this article https://support.mozilla.org/en-US/kb/thunderbird-and-yahoo and everything appears correct

I've had to pay for extra storage to get the code to make this post.

I have a small office with 5 stations to access our one email account and we'd used thunderbird for years, but the lack of integration between the stations meant we changed to Outlook and of course that's a shitshow, so I'm coming back to ask you my self (rather than the tech guy) if there's a way to set up thunderbird so that if desk 1 opens and responds to email 17, that all the desks can see both that it happened and access the responce that desk 1 sent.

We have an IMAP email account hosted locally (as in, not a gmail account, or the like).

I'd be more than happy to pay for a piece of software that I could use. I've used Thunderbird (and Eudora) for decades and I'd like to continue to support it. But moreover, I'd like an email server that doesn't limit my account size (I use email for "corporate history") and one that would allow my individual staff members to see everyone's activity in the email server.

I had most recently (like 6 months ago?) been using thunderbird. My Tech guy said it was the most current version, but I couldn't tell you what it was.

We run on Windows -- most on 11 but a couple still on 10 until I can take the time to set up the new computers.

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?

After I migrated everything to a different computer, 'Local folders' no longer appears in the side bar, so I cannot archive messages locally.

Can some kind person please help me to reinstate it?

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.

Når jeg sletter mails, bliver der stadig ved med at vise en mails som ikke er læst med et flag på bundlinien . Først når jeg trykker på eks. kladeer og derefter indbakke forsvinder dette.

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.

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

Beim Aufrufen meiner Emails auf dem PC, erscheint ein Fenster: Verbindung konnte mit .arcor.de nicht hergestellt werden, obwohl ich Mails empfangen und senden kann. Bis vor einer Woche konnte ich mit gleicher Enail-Adresse auch gleichzeitig auf meinem IPhone senden und empfangen, im Moment kann ich nur Mails versenden, empfangen nicht mehr.

I have app version 18.0. About 20 minutes ago I composed an email to a new contact (responding to a letter he sent me). The email was ready to be sent but before I did so I passed the phone across to my wife to read it. She passed the phone back and the message had disappeared from the screen. I have two email accounts that are Unified. The missing email was written with the main account so I checked in all those folders, including Sent, Junk, Spam, etc. I tried searching for the recipient's email address and tried Search everywhere. I also checked on TB for desktop on my laptop. I thought that composed messages were automatically saved. I have seen this during composition when opening a different app to check something and a message appears at the bottom of the screen "Message saved as draft" or similar. I'm trying think what is different this time. Can you offer any suggestion?

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 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.
