I have an existing Thunderbird account on my Windows 11 PC. I am now trying to open and access this same account on another PC with Windows 10.This is the message that keeps on appearing:

Unable to login in at server. Probably wrong configuration,username or password.

Any help would be greatly appreciated.

When I upgraded from MacOS Ventura to MacOS Sonoma, Thunderbird stopped working. Getting it to work the first time required me to use Apple's 2 Step Verification process to create an app-specific password. After the MacOS upgrade, that process was no longer available. Apple switched to 2 Factor Authentication, which is apparently different and incompatible with 2sv. The other websites and applications on my iMac have already switched to 2fa, and I'm not sure I can have both methods active on the same computer (but I've asked, Apple, anyway).

Is there a recent change in Thunderbird that would allow me to use 2fa instead of 2sv to access Thunderbird?

I have many years worth of emails in Thunderbird that I can no longer access. I can see the directory structure, and some of the email lists, but not the content.

Thanks for the help!

My thunderbird just upgraded to 115.2.2 (32-bit) - my windows is 64-bit - but I can't read the preview window or emails. Everything is in a gigantic font so I see only 2 lines at a time in both the main email edit screen and the preview screen. I tried changing it to Calibri 12 in Settings (it was Calibri 17) but that makes no difference. I also don't like that I have to go through File menu now to get messages for just one account. Is there a way to downgrade back to my old version? I guess that would be 115.2.1. Thank you!

Hello,

Trying every conceivable method to move my Thunderbird data to a new computer, following instructions exactly.

First I copy all the contents of the Thunderbird directory from %APPDATA%\Thunderbird\Profiles\ on the source computer to a USB drive. Next I copy that folder to the same location on the destination machine. I am copying the Thunderbird directory and all subdirectories. Run Thunderbird, no mails, nothing.

Thank you

When in Thunderbird trying to import old profile from backup media using the import tool, I get an error message saying "about:preferences : unable to run script because scripts are blocked internally" How do I manage this? Can´t find anything about it on help pages. / Olle

Thunderbird stopped sending and receiving emails. I installed a new copy of thunderbird on another computer. After some time I was able to get it functional there. I would now like to have the same mail folder structure on the new machine as the old and import all my old information. I have exported the contents of the old Thunderbird profile to a usb drive. There are a large number of files and folder - 167 to be exact. The path the to the profile folder on my old computer was ....AppData\Roaming\Thunderbird\Profiles\t3ozjfx.default. This is the 'Local directory' in the Server Settings on the old computer. The path to Profile folder on the new installation is also ...AppData\Roaming\Thunderbird\Profiles\ but then there are two profile type files. One called t3ozjfx.default as before and another called test.default. The 'Local directory' in the Server Settings on the new computer is .....AppData\Roaming\Thunderbird\Profiles\t3ozjfjx.default\ImapMail\mail.cts.com-1.au It took me a great deal of effort to get emails sending and receiving properly on the new machine. It should have been just a matter of having the correct port addresses, server name, and encription method. However one had to fiddle with the local directory path to get operational

My question is given the above should I be able to get my old email file structure and the contents of those files onto the new computer by using the import facility in thunderbird. I would also like have the 'sent' messages on the old computer on the new computer. Will the thunderbird import operation be able to do this using the profile file information I put on the usb memory.

I hope I have not been too tedious in asking this question. It would be an immense relief if I could get Thunderbird on my new computer to have all the contents and folder structure that I had on the old computer.

sincerely yours

I restored data from Carbonite to a new disk before installing Thunderbird and 'lost' all my folders. I have found the profile file, can I open the profile file and use that to repopulate my files and messages? I run Windows 10 on a Dell laptop.

I posted the following question 1 month ago. Can anyone help me with this, it's driving me crazy! Please respond.

- Open TB - Open Inbox to see all emails - Open an email, read it, delete it - Scroll down, reading email Subjects until I find another email I want to open (this may be 30-40 lines or more) - Open another email, read it, delete it

The cursor/highlight then jumps back up to the previously highlighted email (next to the first email I deleted). Now I don't know where I am, I don't know what email Subjects I have already looked at, I don't know where the next unlooked-at email is. In order to get back to where I was before I deleted the second email, I have to scroll down through many emails I have already scrolled through.

How do I stop TB from doing this? I want the cursor/highlight to stay right where it was before I delete any email, I do not want it jumping to some previous location.

I have two computers, one older with TB 115.9.0 32 bit, pop. The other has 115.9.0 64 bit, imap, same email address. I have tried to merge them, but when i do the Thunderbird Import folder has zero messages and no subfolders. I also tried changing the old TB to IMAP, didnt work: "configuration problem". Any help would be appreciated.

What is the minimum version of Ubuntu to install Thunderbird 115 supernova? I'm on 20.04 on ZorinOS.

And by the way, when are you planning to make it available on APT?

Thanks, Tal Sabadia

Help! I have been stuck on 60.9.1. I tried to upgrade many years ago and lost all my past emails and folders. A search at the time said there was no way to get them back so I reinstalled 60 and have lived there ever since. A couple of weeks ago Google mail changed their security protocols and dropped POP and 60.9 apparently can not read IMAP. I love Thunderbird and would prefer to stay but I don't want to loose all my past emails and folders. So, I would like to upgrade to the latest stable version. Is there a path that won't dump my history? I have read many posts on here but still can't find the path to being current. Can I simply install the latest version or do I have to install in stages. If in stages what is the order of version to install and should I stop at each version to check/test something before moving to the next install?

Thanks in advance for your help.

'They were supposed to transfer everything over and after considerable number of interactions i now have 1 of my 5 emails working . I can send and receive emails on email #1. I can receive emails on email#2,3,4,5 the problem is I can only send messages on email #1 When I go to accounts. - edit smtp server all the 5 user names default to the same user name ( last line) . Which ever user name I put in is the email that I can send emails out. for ex. if the user name is email1@xxx.com I can only send emails out on email 1. if the user name is email3@xxx.com I can only send emails out on email 3 . On the SMTP server edit page ----- Description : office 365 Server name: outlook.office365.com Port: 587 Connection security: STARTTLS AUTHENTICATION: normal password User name: email1@xxx.com I s there a way to separate the user names of the 5 emails

I have windows 10. Was getting a message that Thunderbird could not automatically update and that I would have to download the latest version and install it. I did. I am now on Version 91.10.0 64 bit.

Now every day I get that same message. Thinking its a new download I start to download it only to find its the same EXE file I downloaded last time.

After running the new install, it leaves 2 short cuts on my desktop. BOTH point to the same program name and location.

Is there something wrong with that update? Thanks.

It is 5:46am Sunday morning here in Southern California and again after 3 days of calling Ionos I am not receiving emails sent to me using Thunderbird 102.0.3 especially Spam emails I would like to block and mail in sub folders having saved emails. And this morning I cannot send emails from my TB account. This has been going on for a few days. Back a few days ago I would receive junk/spam mail and add those emails to block list using TB. Now those emails stay in Ionos site mail account and are not forwarded to my TB account. I cannot send emails from my Ionos site when using TB. Why is this a happening and how to fix it. Thanks

I set up thunderbird email account on my computer and my iphone. I can only send and not receive emails on my computer account and I can only receive and not send from my phone account. When I try to send emails from my phone the email bounces to my outbox where it sits and I get a message that says "Cannot Send Mail The sender address was invalid" I think something was off in the initial setup because this problem has persisted from the beginning however I cannot figure out how to fix it. Need help please so that email sends and receives from either location: computer or iphone.

Computer crashed. Trying to reinstall thunderbird. Thunderbird does not recognize configuration info for my roadrunner email. Thunderbird is working fine with that email on my other computer.

System is win 11, latest TB, personal gmail account of long standing. I want to use TB as my email program for gmail. After installing TB, it asks for my gmail login and password, and recognizes the account, defaulting to IMAP, Oauth2, etc. When I press "done", I get a google screen saying that TB want authorization to access gmail files. But when I press "allow", the TB page shows an error message under the password field reading "Unable to log in at server. Probably wrong configuration, username, or password." I understand it is looking for my gmail username and password, and these are correct. I have tried this many times, including with variations: removing and reinstalling TB, creating a pw just for TB in gmail (subsequently deleted). I have read all of the gmail installation help notes at Mozilla. Most relate to a 2022 change in gmail re Oauth2. Nothing helps. Any advice?

I have just installed Thunderbird to my new (Widows 11) computer while still keeping it on my old Windows 10 one. But when a new email arrives and is opened ON ANY ONE of the Thunderbirds, it does not come to the other. But it still arrives to both my ANDROID phone and tablet, and still exists on the server. Seems like only ONE Thunderbird can retrieve emails, which doesn't make sense. Any help?

Hi,

I installed TB on my laptop but i can't setup any email: i tried gmail, yahoo and ik with the same negative result. I'm on setup page, write email and password (remember password check marked), then google page opens for verification and i allow TB to everything. For Google is ok and i received an email that confirm TB is allowed to see, modify etc but in TB error says: "Unable to log in at server. Probably wrong config, username or password" but if it was wrong i can't be log on Google. About configuration, that is automatic, i have this:

Incoming server Protocol: IMAP Hostname: imap.gmail.com Port: 993 Connection security: SSL/TLS Authentication method: OAuth2 Username: mine Outgoing server Hostname: smtp.gmail.com Port: 465 Connection security: SSL/TLS Authentication method: OAuth2 Username: mine

Same problem with other email account I've try to find a solution by reading support but... Someone can help me?
