Thunderbird Support Forum

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?

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!

I have had message filters set up for a long time. Recently I tried to make some changes (adding one filter, deleting others, changing the response). I find that if I close Thunderbird and reopen it, all my changes are gone! How can I get the filter changes to stick?

Anytime I attempt to send an email in the CCC ONE application, I get this error message from CCC ONE:

"Unable to perform selected action while the email application is open. Please close your email application and try again."

This error message persists whether I do have Thunderbird open or not. I also checked Task manager while I had Thunderbird closed and found no instance of it running. Is there any way that Thunderbird is running in the background? Or could it be if Thunderbird loads at start up that it's tricking CCC into thinking it's open all the time?

I contacted CCC ONE report and they advised me to attempt to change the name of a DLL file so a new one would be created to replace it. I tried that, the issue still persists. They also told me to try and uninstall and reinstall Thunderbird, which I did, and it still won't work.

Any ideas on how to fix this?

Symptom:

1. TB stopped downloading new emails for one account on PC.

Solutions Tried without success:

1. Checked Email configuration and settings 2. Restart TB 3. Rebuild Global Database by deleting global-messages-db.sqlite file. 4. Delete Saved passwords. 5. Delete all emails on webserver dating back to when problem began. 6. Change password on webserver.

Additional information.

Current version of TB: Version 115.9.0 Windows Version: Windows 10 Home 22H2 Email Webserver: Ionos Email Protocol: POP3

Issue Details: I use TB on my desktop to manage many different email accounts. Some from Gmail and some from Ionos. Last week, TB stopped downloading emails from one of my Ionos accounts. It still downloads from my other Ionos account and my gmail accounts. I use Aquamail on my Android device and it continues to be able to download emails for this same account. Additionally, I have a laptop with TB and it continues to download emails from this account without issue.

If you need additional information, please ask. Suggesting switching to IMAP is not useful and not a solution to my issue. I respectfully request that you Please do not go there (been down this road before). I want to fix the problem, not go around it.

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.

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 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.

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.

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

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

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?

Hello

Yesterday there was update in Thunderbird and went well. But today, Thunderbird suddenly asking for credentials and then it went totally blank as in screenshot. There is nothing at all. But incoming mails are still showing up in windows notification and it can be opened as new tab of Thunderbird. I have been searching the possible cause and solution from forum and internet, but no luck. Can someone please help me about this ?

MacOS Sonoma 14.4 seems to have broken a number of apps. AFter updating to Sonoma 14.4 I experienced a great number of crashes with Thunderbird, so I completely uninstalled Thunderbird and removed all traces of plists, Application preferences, everything, reinstalled Thunderbird, and added back the two email accounts I use with it.

It now takes up to 30 seconds to start up Thunderbird, after which it happily no longer crashes, but obviously the startup time is unacceptable. I experience the same problem with Typora, and the developers there informed me that they believe the problem is with a Sonoma change that broke WebKit. I don't know if Thunderbird still uses Gecko or if the new version is WebKit. Please let me know if other Sonoma users have reported this problem or if it's just my system.

A while ago, I had to work offline so I had TB download my Gmail account messages. Now I no longer want these messages to be stored locally, because the Thunderbird folder is up to 10Gb, so I unchecked the box in Synchronization for 'Keep messages in all folders for this account on this computer'. I was hoping the TB would subsequently purge the offline folders, but apparently not. Is there a way to clean out the folders without affecting my online Gmail folders as in Inbox and Sent folders?

Every time I open TB email on my laptop I get the following page, which then exists as long as I am on TB. I can work-around this page to send and receive email. Here is the top half of the page:

Mozilla Thunderbird Email wants to access your Google Account undefined jschoolnews@gmail.com This will allow Mozilla Thunderbird Email to: More info Read, compose, send, and permanently delete all your email from Gmail

                      (the same for contacts and calendars)

Yesterday I downloaded Thunderbird to Windows 10 (64-bit), added my Office 365 (for work or school) account, rocketmail account and iCloud account. I created unified folders for the three accounts. I have downloaded the TBSync add-on with the required CavDev (?) one to connect my iCloud calendar.

After successful use the first few times, now Thunderbird becomes unresponsive within 5 seconds of opening, every time, rendering the program unusable.

Troubleshooting mode does not fix the problem, so I assume it's not the add-ons, nor does starting my PC in Safe Mode (F4 at startup ie no networking), so I assume it's not antivirus.

I uninstalled Thunderbird and re-installed from the website today. All my accounts were there (so I wonder if the uninstall didn't work properly, although I assume that it's just the files left on my computer that the new Thunderbird installation is accessing).

All these attempted fixes leave the problem unchanged: the window freezing within seconds of opening.

Because the program becomes listed as 'not responding' and greys out on further clicks, I have to hard-close the program using Windows, selecting 'Close the progam'. Clicking 'Wait for the program to respond' leaves the screen greyed out, and nothing changes for at least 20 minutes (the maximum I've tried waiting it out). This also means that it does not yield a formal crash report, because Thunderbird does not recognise it has crashed.

On one occasion it did create a crash report, which I submitted. I am not sure what behaviour allowed this to happen, and I have been unable to reproduce it. That particular crash ID was as follows:

Crash ID: bp-41096385-eebe-4ccc-a47e-f76300240417

Any help much appreciated! I'd love to stick with Thunderbird if possible.

TB no longer will start. It just hangs and when I go to it on my Mac I see a spinning disk. That never changes and eventually, after hours, I must force quit and report it to Apple. I receive no messages or error codes.
