I have a thunderbird account but switched to gmail and now wish to return to thunderbird but error message 400 from Google appears each time.What do I need to do - in simple terms pls

I have tried many times to add a third email (Gmail account) to my Thunderbird email application. I successfully added both a Comcast and Outlook email account, but Gmail won't install. I'm using Windows 11 on a Surface Pro 8 laptop.

Sadly, my old Windows 10 PC crashed, and I'm migrating to a new computer. I have a backup of the old default profile folder (9k7faw1z.default), but not of the entire Profiles folder. I have tried to import this old default profile using the import function in my new Thunderbird install on my new Windows 11 computer.

Alas, I get the error message "Import failed unexpectedly; more information may be available in the Error Console." I looked in the error console, and it's empty.

Is there a better way to import my old data from my old default profile folder? It's 3GB of valuable data and I'll be in a pickle if I can't access it.

Thanks very much.

Moved to new country (UK) took TB data with me as instructed. Installed TB did put in email data. Uploaded TB data as per instructions. Opened TB and put in email password etc. All my current emails show up no problems and email account appears to work but none of the uploaded data appears even though it took 15 min to upload. It feels like it was uploaded to the 'wrong' place but I uploaded the data it to the TB folder as instructed. Any idea what I did wrong??

Hi,

I created a backup of my Thunderbird profile including various email accounts and calendar. I used the build in export function of Thunderbird to create this backup. Unfortunately the file is slightly bigger than 2GB.

I had a severe copmputer crash now and I wanted to import the backup. It turns out that the zip-achive is damaged. I cannot unpack it with any zip-software and also repairing the archive with winrar did not work.

Is there any chance that I can at least restore some of the information?

Best, Robert

Hello, I have two email addresses, one personnel, one business. The other night, Thunderbird asked me to download an update. Since downloading the update, all my business emails and subfolders are gone and have been replaced by my personnel email address and subfolders. (in the left hand pane - pic attached) The business emails and subfolders are on my main server yahoo, but are not on my Thunderbird program. Can someone help me to recover the business email address emails and subfolders? Thank you.

We've enjoyed T'bird on this PC for several years. About a year ago my wife got a new laptop; it came with Outlook as the default email program. It worked only fairly well, but now it has pretty much bitten the dust. I installed T'bird for her and it's working fairly well, but with a couple minor bugs. First, there is no address book in it and also the menu bar across the top is missing. HELP!!!!!

Until the 9th of april I had no problem since then I keep on getting the message: login to server imap.tools.sky.com user namemorgandavid33@sky.com failed

retry or enter new password.

I contacted sky and I did change my password on their advice and I still cannot login. How do I get thunderbird to accept this new password. Or is there another issue with logging in?

The Sky.com email is now provided by Yahoo. I can access my emails there but I prefer Thunderbird and have used it for some time now. Thank you for your help.

I recently reset my desk top and after that my thunderbird will not open without a password that I have not got. I need a simple way to find the password or otherwise allow me to reinstal a new download. I have tried for two days using lots of suggestions from web and help but I cant get past the request for a password

Hi,

I am trying to add my work email account in Thunderbird, but for some reason the settings do not work in my case. It's really strange, because somebody else from my work is able to connect to their account with the same IMAP/SMTP server settings.

I am using a web2mail Email account and I already had a 2 hour long session with their support trying to find out what the problem is, but it seems that there is no issue on their end. The support there was able to use MS Office Outlook to connect to my account without any issues. And as mentioned before, my colleague is able to connect to her account using Thunderbird. And also, I was able to connect to my account using Spark with essentially the same server settings!

I really don't understand why Thunderbird cannot log in to MY account specifically. I tested it on two different computers with the same result. The error message is in the attached screenshot.

One more strange piece of information: If I change from IMAP to POP3 (with port 995), then it lets me add the account, but is not downloading any emails...

I installed Supernova after almost 2 decades away from Thunderbird. I created an Supernova IMAP account connected with my Gmail account. It was orders of magnitude easier than using Outlook.

I need to open a hierarchy of Thunderbird email folders from 2 decades ago. They take the form of associated *.msf files and, for each, either an extensionless MBOX file or a *.sbd subfolder with the same filename stem as the *.msf file.

I thought that I could simple navigate within the Supernova GUI to open the MSF file, but all it does is show the text of the MSF file in a separaste tab from my email. No hierarchy of folders appears in the email folder pane.

I realize that I can explore 3rd party tools, but these old files are native Thunderbird files. Surely there is a way to open them?

This has been a headache. Cox has had us migrate our accounts to yahoo. I have been able to do most of my emails, but my husband had yahoo tech help him and one of his emails will not download to the thunderbird account. The tech did a pop.mail.yahoo with this one but created new imap accounts with the other two. I tried to create a new account but it says Incoming server aleady exists. So I deleted the account, shut down Thunderbird and brought it up and tried again. I got the same message.

I am new extremely tech savvy but know a little more than my husband. If someone could please help walk me through this, I would appreciate it. Thank you.

Thunderbird invited itself to install on my computer without my permission. I cannot cancel it. It ignores my request. I can't open anything else until it leaves. Please help.

How do I downgrade to an older version of Thunderbird on Rocky Linux (RHEL clone)?

For my last update (yum update -y) I got Thunderbird 115 which has lots of problems.

If I try “yum downgrade thunderbird”, I get the error: Last metadata expiration check: 3:43:41 ago on Tue 14 Nov 2023 04:57:52 PM EST. Package thunderbird of lowest version already installed, cannot downgrade it. Dependencies resolve

I downloaded: https://archive.mozilla.org/pub/thunderbird/releases/102.9.1/linux-x86_64/en-US/thunderbird-102.9.1.tar.bz2 but when I unzip and click the thunderbird icon, Thunderbird doesn’t pick up my Thunderbird profile. I saw some windows downgrade tutorial that said to delete compatibility.ini from profile but when I deleted compatibility.ini Thunderbird still doesn’t pick my profile.

The hard drive on my PC running Windows 10 crashed and I have a new one running Windows 11. I used Thunderbird on the old PC and am trying to set up Thunderbird on the new PC. My email account is with AOL. When setting up Thunderbird on the new PC, it asks for the password. I am trying to use the AOL password but it does not work. The same password works on other devices. I have no access to the data on the old hard drive. Any suggestions greatly appreciated.

All of a sudden I get: Thunderbird failed to find the settings for your email account

and so I have no access to my local folders where I store all my emails. Any ideas what has happened? And more importantly how I get back to my email interface on launch. Thanks in advance

New Computer. Windows 11. I installed Thunderbird. I get my email. It doesn't delete any deleted emails from the server. Also, contacts did not come over. I must have set something wrong. What do I need to do?

Will the option to import Outlook ever return to Thunderbird? I'm using 123.0b5 (64-bit) Beta which does not have it. There is an option (#4) which allows an import of a ZIP file. But can I just ZIP an Outlook OLM file and go that way? Thanks for any help.
