There are two "bad email" files in Thunderbird: JUNK and SPAM. I'm still not clear on the difference.

For JUNK mail, TB gives us the option to select "NOT JUNK". Good.

But for SPAM, I cannot find the option "NOT SPAM"

1) Why are there separate SPAM and JUNK directories? And why are they managed differently? This seems terribly non-intuitive and inconsistent and just strange.

2) How can I train SPAM filter to not flag good email from trusted senders? For instance, I get email from my wife many times a day for many years. Today, TB put her email into SPAM. Isn't there a simple command to "white list" a sender's email address?

Tried to establish Thunderbird on new Laptop Bell Latitude and all e-mail accounts but one could be installed again. Only mak@koepcke-homberg.de settled at www.ionos.de does not fit despite fully accurate details, quite the same as on PC at home (Thunderbird!), Android Mobile (K9), Tablet Galaxy (Samsung E-email). Please see attached Screenshot! Happy to receive your advise...:-) Arnd

When I try to send an email from Thunderbird sometimes it succeeds and sometimes it does not. Trying again sometimes works and sometimes fails again. It may take many attempts to get a message to send.

The "Sending Message" dialog box gets replaced by a "Send Message Error" dialog box saying, "Sending of the message failed. The message could not be sent because the connection to Outgoing server (SMTP) smtp-mail.outlook.com timed out. Try again. OK"

Thunderbird version: 115.9.0

SMTP Server: Description: Office365 (Microsoft) Server Name: smtp-mail.outlook.com Port: 587 Connection security: STARTTLS Authentication method: OAuth2

Operating system: Windows 10.0.19045 Build 19045 ISP: BT Broadband Antivirus software: AVG AntiVirus Free 24.1.8821.822

Please advise on how I can get all my messages to be sent successfully first time. Thank you.

I have used Thunderbid for many years. Lately it is extremely slow displaying and deleting emails; and is not saving passwords. It is fast enough to display images once the email is on the screen. I have tried reindexing and have added T to Windows Firewall allowed. No other antivirus on the machine. The problem is the same for imap and pop accounts. My profile has been on a NAS for several years but the slowness is only recent. I don't have any add ons. A possible clue is that there are multiple email folders in the profile - see attached screenshot. Should I delete the -1 -2 -3 -4 folders - and the associated msf files? The profile as a whole is 869 MB - 2168 files in 142 folders. There is lots of space on the disc. There are a lot of -1 folders across the profile.

can i shut it off this way I do not gnat encryption and i am using Norton a d i also use ccleaner and glary does this have anything to do with it

I've just completed a new install of Thunderbird on a computer (Windows 10 -release 115.8.0 32 bit) and find that the message list does not have the usual columns for From, Date, Subject etc and no column headings. Instead each message in the list has the above message characteristics spaced out over two rows. This format applies to all three Layout Views (Classic, Vertical, and Wide). I prefer the usual column format which allows for more messages to show since only one row is used per message.

How do I get the usual columnar format to show in the message list window? I'be been all over the View and Setup screens and just can't find any function for this.

Thanks, JS

I was a happy camper until V115 stuck its ugly nose into my interface.

Fonts on the interface are absolutely terrible and almost unreadable and cause rather severe eye strain.

I have tried going to Settings->Language & Appearance->Fonts & Colors->Advance and they will not change.

What am I missing.

I noticed that New Times Roman wasn't available as a font. What gives?

I have a very small Tablet computer and Thunderbird is really bogged down on it. The tablet has a 32 bit processor, 1G RAM, 64G SD drive. (1) When I run TB I get many "not responding" messages from Windows. (2) Maybe 1/2 the time, if I "delete" a message the screen will freeze on the message. The message is removed from the inbox list. I have to click "X" to get rid of that screen. (3) Get Messages no longer works. When I click it, nothing happens. The status bar at the bottom remains on the last information displayed. I found that if I use View, Folders, All, I can bump TB to get messages. (Normally I use Unified Folders) The status bar will display each of the accounts it is checking and any new messages will appear. These things have been happening through many many versions of TB. Although #3 seemed fixed a few weeks ago but has returned. Same for #2.

I looked at the disk space that TB is using and found that TB is using over 10GB. See attached. I don't know why it is so large. I don't need to store any messages on this computer. I have a desktop that is my "base station" where I want to save all (but deleted) messages.

I don't know if this large amount of TB space is contributing to the problem. Any help would be appreciated.

When I click "Compact Folders", e.g. when in Inbox, all folders are compacted except the Junk folder. I need to do it again clicking on Junk folder and again "Compact Folders". Is that normal?

I have Thunderbird 115.9.0 64 bit on the 2nd latest version of Ubuntu Linux and by second latest I mean it is still supported even though there is a new version available. Several months ago there was a password problem with my internet account preventing me from logging into my internet/email service and all my devices could not send or recieve emails. I changed my password on my cell, my Windows 10 computers and they worked fine. My Thunderbird on my Ubuntu on the other hand rejected my password and I also checked all of my port and server settings with the help of my internet service provider tech support including comparing settings from other email clients. Still no password being accepted. My internet/email service provider tech agent suggested removing my account from my client and reentering it and this worked.

Several months later I changed my main email passwords again on incoming mail and outgoing mail servers on my account, verified my port settings are correct, which they were including the type of security and protocols used. When I select the desktop icon I get prompted to enter my main password and hit enter and the window keeps reoccurring as if it has rejected my password. I select cancel allowing me to enter and again clear and reenter password and again it is rejected. I removed my account (I think) and go through the motions of reinstalling my account and get a pop-up indicating the server already exists which puzzles me. Ports, security settings, password are all correct and tested on other devices. I can even use a browser and log onto my internet service providers server and access my account and my password works but not on my Thunderbird. Should I consider uninstalling and then reinstalling my Thunderbird on my Ubuntu? I think by mistake I deleted all of my emails BUT I have selected IMAP so my emails I want are still on my service providers server. IF I uninstall and reinstall how do I save my contact list. This I Inoticed is still intact. Suggestions please?

Made a mistake and installed 157.7.0 on Linux

Now cannot backup/restore to another computer so cannot use that computer.

Old Profile used to be in .thunderbird folder - easy!

Now profile seems to be in /home/oem/snap/thunderbird/common/.thunderbird/26pphmrb.default

This does not contain all emails especially for pop3 and anything after Nov 23. It does not work

Q's

Best way to fix? Can I force it TBird to read the .thunderbird in home directory? Can I install an older version of TBird easily? Is there some other way to restore the profile and clone another computer?

I'm getting a "nonoverridable TLS error" message when Thunderbird first opens. Also, new emails won't download into my IMAP account. I've tried adjusting the incoming and outgoing server port settings and even turning off the antivirus and phishing email scanners. Nothing works. It's now 1:59 PM on a Thursday afternoon and I've received no new emails since 11:20 AM. Please give me security settings that will work.

Occasionally I will see a set of Email messages that look exactly like the one in the attachment in the message body window. When I look at them on another client, they are fine, so I think they get downloaded to my Thunderbird incorrectly. I have about 10 or 12 messages that look like this (no change at all between messages).

Two questions:

1. Is this a problem others see (I only get it once in a while, both in the beta that I stopped using and in the current version).

2. When this does happen to me, what can I do to refresh these messages? I have not found anything in any of the menus that looks like it would help. I have cleared cache.

Thank you.

TIA , Windows 11 Oops... Going from TBird Portable to Thunderbird 115.9.0 (64-bit) SuperNova I accidentally ended up with Thunderbird 115.9.0 (64-bit) SuperNova , (TBS). And I notice there is an entry in 'Installed Apps' for Mozilla Thunderbird (x86 en-US) But when I look in C:\Program Files (x86) there is no Entry for TB . Moving on ... TB Portable has Folders for 'App' 'Data' 'Other' TB Supernova (TBS) has no such Folders . And Looks Like I'll have to re-Build all my email accounts (10) .

How to proceed? : Shall I unInstall 'Installed Apps' for Mozilla Thunderbird (x86 en-US) I do have a Backup for: TB Portable has Folders for 'App' 'Data' 'Other'

I have tags I no loner use and would like to delete them from my tag list. I haven't been able to find a way of doing this. Manage Tags lets you edit the name and color, but not delete. Is there a way of doing this?

Thanks!

Hey, everybody. Here's a screenshot. How to increase the size of the lines with "item", "from whom", "to whom", "date", "time" ? Modifying userChrome.css with this syntax did not solve the problem. .tree-rows {

 height: 25px !important;

}

1. threadTree treechildren::-moz-tree-row {

 height: 25px !important;

}

I mean how to increase the height of these rows, make the rows wider? Thank you all in advance and have a good day.

Dear reciever. After years of using TB and what we do think is a productive mail-tool that works for the benefits we are looking for has worked. However, the last 115- constantly freezing and shuts down. This is very annoying. It freezes at some folders from the main email-client- as we have deleted older folders integrated with this. But the problems remains. . We have done everything in our knowledge of the program but still no approvement. . At this point we are using Outlook..would be grateful to have some answers and possible sollutions for this issue. . Thanks in advance and keep up the great work U are doing. :-)

I had growing problems ever since updating to Supernova. I updated again to 115.5.2 which didn't help. So I thought, right, start again. I uninstalled Thunderbird and installed 115.9.0. Now I have no folders in the folder pane and no messages. Please see screenshot. I have checked that Thunderbird is using the right profile. I have 1 IMAP email account and 23 POP3 accounts, 19Gb of messages going back many years, all saved for good reasons, mostly business. I can't see any of them, nor incoming messages. Windows 8.1, long term Thunderbird user and donor. Michael, UK

Threading is something I, and indeed large numbers of Thunderbird users, do NOT want, ever.

Please provide an option to disable threading, across all folders, all acounts.

Even worse, the option to Ignore Thread, is simply a way to lose emails. To have a shortcut to hide a message, without even knowing, is crazy. Given how poor Windows control of focus is, and how easy it is to start typing but actually still be in the email listings, its inevitable that you will hit e.g. K or A or whatever, and cause bizarre effects or lose emails.

So I want to disable threading to avoid losing emails. I would also like to disable Archiving, and other functions, that are all simply ways to lose emails by accident.

Thanks.

Since changing my email password on my BT Mail server, Thunderbird will not send emails. I get a popup saying Sending and a blue line which never completes. When I cancel it I get the following:

Sending of the message failed. Unable to authenticate to Outgoing server (SMTP) mail.btinternet.com. Please check the password and verify the 'Authentication method' in 'Account Settings | Outgoing server (SMTP)'.

There is no password change option on the Outgoing Server (SMTP). Connection Security is set to SSL/TLS and Authentication method is "Normal Password".

I can receive emails with no problems.
