Thunderbird Support Forum

About 2 weeks ago, Thunderbird stopped sending emails. I spent a couple of hours on the phone with tech support but was unable to correct the issue. Changed all of the settings several times, SMTP server, port, security and authentication without success. Tech support suggested using their server but that's a pain. Attached are pictures of the error messages. Thanks.

Today I tried to look up a previous email that I'd filed in a subfolder, but the folder displayed no emails. If I click on the subfolder above it, it shows me the number of emails and displays the list of emails. Then when I click on the subfolder I want, it displays the name and number of emails for the previous subfolder I looked at.

I tried troubleshoot mode, but still no luck, and the folder is gray instead of yellow like all the others.

I'm using Thunderbird 115.9.0 (32 bit), Windows 11 Home 64-bit.

I've been using Thunderbird for years and have never had this problem before.

Hoping someone will have some advice!

Thunderbird - Problem

My email address is: finnvebirk@webspeed.dk (alias: evab@webspeed.dk ) I have used Thunderbird email for many years. I have archive folders with more than 50 folders and sub-folders. Overall, I have several thousand emails in my archive folders.

After I wanted to create a sub-folder and move it to another location, the following has happened: All my folders and sub-folders are mixed together and arranged in a changed order. All emails in my archive folders and sub-folders have disappeared - all folders are completely empty. I think maybe a folder called 'Local folders' has disappeared. It is no longer possible to move emails from the Inbox to the empty folders. NOTE: Inbox, Sent and Trash still works.

Question-1: What happened ? What can I do ? Can I recover all my emails in the archive folders ?

Question-2: Can I restore my Thunderbird mail system as it was, e.g. 2 weeks ago ?

Question-3: As an emergency plan (if all my emails are lost !): Can I reset Thunderbird without deleting mails in Inbox, Sent and Trash ? If Yes – How do I do that ?

When I start T'bird in normal mode, I get what you see in picture #1. Notice the custom menu bar at the top. I can still receive emails into the Inbox (but can't see or access them), and I can write an email, access the Address Book, Calendar, etc.

When I then start in Safe mode, with Shift key down, I get what you see in Picture #2. Notice that the custom menu bar at the top is gone. I have to recreate it every time I shut down and restart T'bird. That is unacceptable.

Please advise what I should do to correct this situation. If I can't, then I'm through with Thunderbird (after some 15+ years).

Many thanks, Robert Hawkins

I want to setup my Gmail account that my school hosts. It has a unique domain name and Thunderbird does not recognize it as a Gmail account, but I'm sure it is. Here's what I did to solve the problem (yet no luck) First, I tried to setup with manual IMAP configuraiton by following the steps on LifeWire Article and Google Support, but it says that credentials that I'm using is wrong. It did detect the Gmail mail server though. Next, I tried to pretend that I'm going to login as a user I've created ON GOOGLE so thunderbird can recognize it as Gmail Account, then logged in with my school credential, and it failed. Probably because I've entered fake Gmail address in the form. It's very inconvenient that I cannot setup mail accounts with OAuth authentication method manually.

Do you have a walkaround for this?

Title. Thunderbird is a really cool client but it's pretty slow. I blame that on the thousands upon thousands of emails that my hotmail and gmail each hold. I don't necessarily want to delete these emails, but I have seldom a reason to have any email older than 2 months in my thunderbird client slowing and crashing the program whenever I want to combine inboxes.

To this end I went to "Synchronization & Storage" and told it to "Synchronize the most recent 2 months" but it didn't delete the huge cluster of older emails. The next option is to tell TB to delete these emails in the same menu but as I understand it that would also delete them in the server, which I don't want to do for posteriority.

What do I do?

Thunderbird runs slow...ie when I type an email I can easily type faster than thunderbird will accept characters....(this does not happen in other applications)...this happened about a month ago, and then stopped ( I have no idea why)...but the problem is back. I am running Ver 115.10.0 build 2024012173147. Rebooting windows 11 makes no difference.... I just tried to enter Troubleshoot mode and thunderbird stopped responding....Top line says Mozilla Thunderbird (Not Responding). Thunderbird is connected to my gmail account. ...and I run IMAP....with 'store all messages on the computer', but thunderbird wants to load every email from the server'

Any advice would be appreciated Rick

Have used a Onetel e-mail account for a number of years.

Occasionally, the outgoing server drops out so messages can't be sent only received.

When trying to reconfigure with correct port numbers etc it will never reconnect straight away and there is always a long process to get it up and running again which always seems different every time.

I can never manage this by myself and always have to get help in. This has baffled the best brains in the business so any help or advice gratefully received.

I have an issue with using newgroups via NNTP server in Thunderbird. News only load during startup of the program. Whenever the option Get Messages is chosen later, or when it is automatically run by the program, the process seems to get stuck in a loading state. In this state neither can new messages be read (the headers seem to be there and are shown, but the body of the message isn't), nor can new messages be sent (message sending gets stuck in status "Assembling Message")

This has been the case for a few releases already, and is currently present on 115.10.0 (64bit)

I am going crazy. This message keeps popping up every time I turn on my Thunderbird email program on my Windows 10 laptop! Please see the attached file. I shows you the popup and what happens when I click on 'Next'. I 'x' it off, and a few seconds later it pops up again. The only way to stop it from doing so is to turn off my Thunerbird program. I like to keep it on so I know when I get emails. PLEASE help me get rid of this. Thanks so much.

I'm getting login issues to my Outlook account. I understand this is an emerging problem and I"m following the instructions here: https://support.mozilla.org/en-US/kb/microsoft-oauth-authentication-and-thunderbird-202

However, I can't follow the instructions under section "Change Thunderbird authentication method for sending messages (SMTP)" because I don't have "Outgoing Server (SNMP)" in the lefthand side. I do have an option to edit Outgoing Server settings, but there is no option to set OAuth2 in the Authentication Method dropdown. I am unable to send Outlook emails, and I'm unable to complete the instructions to fix it. Help is appreciated!

PC is an Apply Mac Book Pro running latest operating system software: Sonoma 14.4.1 ... after installing 14.4.1, Thunderbird slowed down in all facets: loading mail, opening selected mail, deleting mail, etc. Anyone else experiencing this issue, if so, were you able to resolve it and how? Thank you!

I'm running thunderbird on ubuntu 22.04 connected to external samba shares. I've used local folders on this remote location (samba shares) for may years. Two days ago, when I've try to move message from mailbox to local folders I've received error "not enough disk space". There was a plenty of space on that remote location. After several attempts to solve the issue I've found that problem happened when local folders are located remotely. When they are defined as local then everything work fine. I've try to cheat making symbolic link for local folders or even for single subfolder. Result is the same. Everything work fine if local folders are located locally on file system. Any remote location, direct or via symbolic link and even for subfolder, don't allow to move any message to that remote folder. There is enough space and proper R/W access tho that remote location from this machine. How I can return to my normal operation with local folders on remote location?

Dear sirs,

I believe that Thunderbird is one of the best email client programs available. This believe is the reason that i am trying to migrate to your email software. Sadly i have been experiencing a some dificulties on my main machine. I’ve tried for several times configurating the email on thunderbird, with sucess. The problem resides on every time that i close the program or restart my computer my email account vanishes from thunderbird. I am using an exchange2019 mail box. Could you please help me out with this situation.

Besr regards, Joaquim Nunes

Previously, for years, selecting and deleting groups of emails took only seconds. For sometime now, the more emails selected to delete as a group causes the amount of time to do so to become longer and longer. Minutes go by. It feels like instead of dealing with all of them at once, it's deleting one at a time, but that's just a guess. What can I do to get back to where it used to be? Thank you.

My emails have large a lapse in time before the downloading catches up. For example right now my last email showing says 6:41 PM when it is actually 9:44 PM. This is costing me sales on items I have listed on the marketplace because I have no current notification via emails. Please help.

I'm about the 100th person to have this problem, so I have spent the better part of two days looking at all the threads and possible fixes. Like all the others, with no warning, my TBird stopped being able to send messages through Spectrum. It did NOT start immediately after I updated TBird to 115.9.0 (in March) but just three days ago. I have three roadrunner addresses in TBird, and one other one associated with a website I have. All have the same problem. My phone and my iPad send messages just fine.

I tried all the fixes that worked for some. They didn't work for me; I continued to get various, inconsistent Send Message Errors. I have come back to the recommended Spectrum setup for the outgoing SMTP server: mail.twc.com, Security is STARTTLS, Port 587, Authentication is Normal Password, my username is my email address. Of course the problem is not fixed.

What DID work was putting TBird in Troubleshooting mode, using the Spectrum setup above. While that is adequate, I would much rather find out what is wrong. I have Matt's 10/7/23 11:56 AM answer to someone, asking for the Troubleshooting Information. I will be glad to supply that but I need an answer to this message in order to do that. Thanks! Demaris
