I upgraded my PC, having backed up everything on Carbonite. On installing Thunderbird I cannot get it to recgnise and use my original Thunderbird profile downloaded from Carbonite. Peter Millar

I have windows 10 with 4 Email accounts on my desktop computer. One is TB using ee.net 3rd party provider, two are TB using Gmail and one using Outlook. The Gmail accounts and Outlook work ok. The remaining account with ee.net has been a problem for weeks now. It will not install. EE.net says NOT their problem because all Emails are received and sent OK on their webmail server. They will not help further. I cannot find what is at fault, TB, ee.net or both.

I can't create an IMAP account even though ee.net says their server handles POP3 and IMAP. After long trial-error, POP3 installed manually but sending/receiving messages has server errors. Incoming: mail.ee.net port 110, no security, password insecure. Outgoing: SMTP.mail.ee.net port 587 ssl/tls Auth2 Messages to it have "server refused" error & messages sent say "outgoing SMTP server failed".

Here's the biggest mystery: At one time I found a "magic combination" where all at once everything started working and all waiting messages suddenly downloaded. However, without changing anything, an hour later it returned to earlier non-working condition. It did that once before when I logged out of the ee.net web site and then logged back in. It then asked me for the password again and when I did that, everything started working but quit a day later.

Re-entering the ee.net password again didn't fix it. So, now I ask, how can a fix work only temporarily??? I've chased this problem for weeks now. Art Towslee towslee1@ee.net

Hello, I have an Outlook.fr account and I can't import messages from it into Thunderbird. Here are the installed settings: 1° IMAP = outlook.office365.com Port: 993 Connection security = SSL/TLS Authentication method = OAuth2 2° SMTP = smtp.office365.com Port: 587 Connection security = STARTTLY Authentication method = OAuth2

When I go to Outlook.fr via my browser, I have no problems accessing the Name account (Mail address + Password). What do I have to do to make it work? Thank you for your reply. Have a nice weekend.

Under no circumstances is thunderbird loading a profile (existing or newly built).No crash report. Completely empty. New installed program and/or new installed post boxes + copied Mail-folders from existing profiles into a new profile will work once or twice or a few more times. At least next day TB starts only complete empty. I tried to fix it many times - using corresponding different forums.

Some customized search criteria work as expected, e.g. Content-Type, Message-ID, In-Reply-To, ...

Some not: Content-Transfer-Encoding, Content-Disposition

Some may appear more than once, e.g. Content-Type.

Searching for contents of such criteria / tags yields no results.

How to customize search for these criteria properly?

Below is a shortened source / example addressing all of these issues:

Last week my usually reliable 'Thunderbird 115.8.01 on iMac 10.13.6 has suddenly gone haywire.

* In the folder pane, multiple folder duplicates reappearing even after deleting them. (See images) * And when I delete messages, they appear in the trash folder, only to disappear and repeatedly reappear - back into the message INBOX. * Also, after making a change in the Notification section to turn off the notice sound, and although the sound turned off, so did the auto-disappear function. Now I have to manually "close" each and ALL notification notices one-by-one. The new problem is: now the notification option section has disappeared in settings. (No image for this one. Nothing there!) Bug? Or something else?

Please help. P.S. I ran both of my antivirus programs twice. Each over different days and both declared' my system clear and clean.

When I compose a text message in TBird to send, it starts a new line after __ characters. I want it to occupy the entire screen width, and set it to show me a larger font. I recall there is a way, but searching has not turned it up. Would appreciate pointers to both settings.

I'd be happy with an answer, but I offer a possible solution. Can someone tell me whether it will work?

When more than one copy of an iMap account exists, there is a problem with Junk mail learning. Namely, the learning only occurs on the computer where the user declares mail to be Junk, not on other copies of the same iMap account. It has been suggested that Training.dat be copied from one account to another, but that wipes out any training that has occurred on the copies that receive the new Training.dat file. A merge is needed.

So... Does THIS work? Go to the Junk folder and select all mail in it. Mark all the mail as Junk (seemingly redundantly). Unless Thunderbird makes a special case of NOT learning from marking mail as Junk when it already is, this ought to work, right?

Hello helpful community, Yesterday after first updating my mac ios, I updated Thunderbird (as directed) on my macbook pro and discovered that my local folders are gone. I now have version 128.7.0esr. I have read other conversations here about this problem but they are WAY over my head, and seem to do with PCs. Can you help me restore my local folders with instructions I can hopefully understand? Thank you!

How do I report an issue with the way NVDA and Thunderbird interact? When I tab, I can't out of a link, and the focus does not move. If I tab to a link in a message then arrow down, I am where I expect, but then if I go to the top of the message, the tab focus remains where it was when I last hit the tab key. This is not standard behavior, but everyone else I've talked to seems to think it's behaving normally and has no tips for me on how to fix it.

Hello When I upgraded my Kubuntu 20 to 24 recently, I lost Internet access. So I installed Kubuntu 22 and upgraded to Kubuntu 24 which restored my Internet access. Consequently I am now trying to restore my emails in Thunderbird from my last backup. It took me while to realize that relevant Thunderbird profiles.ini wasn't the one in the Home > hidden .thunderbird Rather the profiles.ini is in Home > snap >thunderbird > common> .thunderbird That snap fooled me for a while ! So documentation doesn't mention snap, anyway I found it eventually. Also some documentation mentions profile.ini whereas it is actually profiles.ini ... plural. Sorry to be niggly. So now my profiles.ini looks like this: [Profile1]

Name=default IsRelative=1 Path=y72gpdv6.default Default=1

[InstallFDC34C9F024745EB] Default=3f6mpdvc.default-release Locked=1

[Profile0] Name=default-release IsRelative=1 Path=3f6mpdvc.default-release

[General] StartWithLastProfile=1 Version=2

I discovered that putting y72gpdv6.default from my backup in the code block at the top like that enables me to see most of my emails when I run Thunderbird. There are 4 blocks of code. Could you please tell me that the blocks do? There are 3 defaults, in fact 1 default and 2 default-releases. What is the purpose of the 2 default-releases? Should I change them, for example replace them with something from my backup? Naturally I want to be sure that I have recovered everything. My original profiles.ini only has 3 blocks of code. Of course, I considered just replacing the new profiles.ini with the original profiles.ini from my last backup, BUT the new profiles.ini has 4 blocks of code instead of 3, hence I'm trying to understand how profiles.ini works. I would appreciate any help. Thank you. Ron H

I get the error message shown in the attached screenshot when downloading my emails from outlook.com to a local folder called "DAD". Some messages get filtered, some not. Those that don't get filtered successfully remain in the Inbox, but a message with empty content does appear in the local folder, and cannot be deleted or moved. Re-running the message filters manually will moved the affected messages across, but the "corrupt" message remains in the target folder and cannot be deleted or moved.

The drive that the folders are located on is my data drive, which has c 250gb of unused spaced. WIndows 11, Thunderbird 128.6.1 (64-bit), installed a few days ago when I moved from another machine.

ADDENDUM: Compacting the folder does not help either!

Has no-one come across this recently? - I have come across some old posts, the suggested solutions for which do not apply.

Dear Team After Updating from 102.15.1 (32Bit) to 115.28.0 (32Bit) I can not connect to the provider "pop.hispeed.ch" anymore. Ping pop.hispeed.ch (on CMD) shows normal raction of beeing reachable with a "reply from xxxx.". I am on Windows 7 SP1. I have checked several times all setting POP and SMTP, switched off Firewall, uninstalled virus scanner, and and and many more (all knowledge found on internet..). Pressing the "Get Message" button in the upper menue bar shows no raction when pressed. The icon "Get Message" on the left side of the button "+ New Message" results in a none moving blue status bar at the right bottom of the window. After a while with the message "timed out.. ".In the settings "Config Editor.." the values of "mailnews.tcptimeout" are set to "300", and "true". I am using TB since donkey years with many many eMails. Are the lost? Thank you for support and help, Andy

Hi: I've just recently installed 135.0.1 Mozilla Browser and have found that the file SAVING-function in the 'Application Menu' does NOT PROPERLY WORK: it records my message-title but NOT the contents (0-bytes!) -I never had such a basic issue in many years of very satisfactory Browser-use ...am I have a wrong setting somewhere and is there any quick fix please ...? - Email me when someone answers the thread ...MANY THANKS, Tony H.

P.S.: Please send me a link where I'd get a help since I'm NOT GETTING ANY HELP FOR SEVERAL WEEKS ...! Thanks-Tony H.

On a new Thunderbird install only some of the subdirectories are being displayed. This is only happening on one email account (xx@live.com). This happened before and I think it had something to do with a filter but I can't locate the issue.

Hello! I have used Thunderbird for many years. Lately, it waits much too long to prompt compacting all accounts. When "Compact all folders when it will save over ..." is set down to 1MB total, it still does not prompt until it has to clear 30 or 40 MB.

It didn't do this in the past, prompting me every 2 or 3 days at higher settings. So, I'm curious if this is "normal" now and I need to manually compact, or if there is a problem with 'Account Settings > Disk Space > Compact all folders' ... ?

I get this error message when I try to send an email....this has been going on for days

Sending of the message failed. An error occurred while sending mail: Outgoing server (SMTP) error. The server responded: resomta-h2p-555359.sys.comcast.net resomta-h2p-555359.sys.comcast.net Excessive failed authentication, ESMTP server temporarily not available.

Please help me resolve this

I installed TBird app a couple weeks ago and everything was working fine. I didn’t use that computer (Win11) for a couple weeks. When I tried to use email this week, using TBird, I got a message saying: ‘Login to server pop.centurylink.net with username drhart@embarqmail.com failed’ I reset my password and nothing changed in Thunderbird. I deleted the T-Bird app and reinstalled. The email name is showing along with the Inbox and Trash folder, plus the local folders are visible. When I click on the Get Messages icon, I get the same message: ‘Login to server pop.centurylink.net with username drhart@embarqmail.com failed’

I have no problem logging into webmail on the same computer. Also, I have no problem getting email on other devices; Win10 laptop using Outlook, iPhone using Mail, android tablet using native mail app.

Thank you for your attention and assistance.
