Hello,

I have the latest thunderbird (128.5.1esr (64-bit)), running on Windows 11 and connected to a mailcow server.

I am having problems with creating calendar events - they are created 1 hour in the future. They show up fine in thunderbird, but Mailcow/SOGo and mobile phones, etc all show the incorrect time.

If I create an event outside thunderbird, or edit it outside thunderbird, all is ok.

I have opened the error console, and it gives me a number of warnings "Calendar: Could not find definition for W. Australia Standard Time"

I am not sure where it is looking for this - but that is the timezone my computer is set to, it exists in the registry, etc.

There is an attached screenshot with more details of the error - maybe its java library issue or something?

Regards, Mal.

I used thunderbird since 2006 till now, but the present thunderbird was wrong somethings.

I used the imap mail on Thunderbird, and I created the Folder from lists below;

When I created the 25 message filters and run from inbox it's Work.

Example : Filters 1 Marketing Managers From contains : managers@xxx.xxx To contains : managers@xxx.xxx Move message to folder Marketing Managers under My Company and Marketing and sub-folder Marketing Managers

Filters 2 Marketing Customer Company A From contains : marketing@abc.xxx To contains : marketing@abc.xxx Move message to folder Marketing under My Customer and Company C and sub-folder Marketing But when I closed thunderbird and open again.

The alert pop-up will show about the filters can't move to destination folder. Then I'll check the filters again and found the problem with Perform these actions could not find the destination folder, I selected again and try to run It's work. After then I try again on next days. The alert pop-up display again.

Thunderbird 112, no message filters problem, but install new version (128.5.1 esr) found problem.

Anyone advice for solve or correct this problem.

I just entered the code you sent for the password for Thunderbird; but, I cannot log in on my pc using my accepted hotmail password. I get message stating: user name xxxxx@hotmail.com failed. Please help. Thank you.

Edit: removed user name

Update: Issue below solved. I have no idea how. Suddenly started working a couple of hours after first reporting though I did nothing after posting the original issue. All is good but I don't know why, how, what, or where!

I just did a routine windows 11 software update after which my emails on my Comcast account are suddenly not accessible by Thunderbird. Thunderbird loads fine but when I try to sync (or when Tbird automatically tries to sync) with Comcast, I get an error message box:

Login to server imap.comcast.net with username xxxxxxxxxxx@comcast.net failed

I don't know what to do to try to get Comcast to recognize and permit Thunderbird to resume normal operation.

I closed then re-opened my Tbird app and I got a popup to put in the comcast password which i did, however after doing so, I got another popup box with the following:

Mozilla Thunderbird ESR Thunderbird Alert from acccount xxxxxxxxxxxx@comcast.net: Temporarily blacklisted IP address -- try again later.

Any help greatly appreciated! Currently, my Tbird is nonfunctional.

Thanks!

I unexpectedly got a message "Login to server imap.comcast.net with username johnmckiernan@comcast.net failed."

Thinking it was odd, I followed through setting a new password. The password works for Firefox logging into the comcast/Xfinity site. I can also have it work on my iPhone/Apple Mail.

But it doesn't seem to work through Thunderbird.

Back in September, 2024, Microsoft Outlook no longer accepted my long-used login information via Thunderbird. I could still log in to https://outlook.live.com/owa/?realm=hotmail.com from the Firefox browser. I tried adjusting Account Settings (e.g. Server Name, Server Type [POP], Security/Authentication, etc. to no avail. I downloaded the current version of Thunderbird (128?) and tried installing per directions found here. Tried using the Flatpak path. The direct Command Line path yielded the same result.

dave@Sequimer:~$ sudo flatpak install flathub org.mozilla.Thunderbird [sudo] password for dave: Skipping: org.mozilla.Thunderbird/x86_64/stable is already installed

I've done a backup and moved to lesser machine which works but it is slow and I want to get back to the original configuration. Now I'm accumulating saved emails on this backup machine while prior emails are saved on the original machine. I'll want to merge them when the login problem is resolved.

Thanks in advance for your attention to this.

I installed Thunderbird from the internet and it was pretty seamless, but I don't think I correctly responded about contacts, because everything from my 2012 macbook seemed to transfer but the address book is empty and I have tried many ways of transferring unsuccessfully, and my apple mail won't let me import its addressbook.

If I uninstall the program and reinstall it again, will it work if I answer yes to the contact question?

Hello,

When I try to access my email via Mozilla's inbox it says that the password is failing. I have tried to create a new password but no emails are able to come in or get sent. I would like assistantce in account recovery as I have had the account for at least 20 yrs

I am using T-Bird 128.5.1esr 64-bit on Win 11, but this problem has existed for a while. Nothing will be displayed if I have the folder checked to show all mail. See screenshot. This is occurring in several folders, not all folders. Unread mail will display. I have tried repairing the folders.

I've been using Thunderbird for years with multiple google accounts on both Windows and Linux machines, no issues. On my main Windows computer one of the accounts started asking for authorization on a regular basis 2-3 months ago. I deleted the account, hoping to fix the issue, but when trying to add it back, I am stuck with this persistent issue:

- I get to the stage Mozilla Thunderbird Email wants to access your google account.
- When I click Allow, instead of finishing the setup, it brings another popup window: Authentication required - Mozilla Thunderbird.
- No matter what I enter there (full gmail address, just the gmail name etc), it's not accepted, and the same window pops up again and again.

I tried to reinstall Thunderbird a couple of times, and also deleted all files inside C:\Users\xxx\AppData\Local\Thunderbird and C:\Users\xxx\AppData\Roaming\Thunderbird . No change.

The issue affects only this particular computer, only this particular gmail account. All other gmail accounts work fine on this computer, and on my other computers (Linux and Widnows ones) all gmail accounts work fine, including the one which I am struggling with on the first computer.

There seems to be some caching going one which cannot be defeated by uninstalling Thunderbird and deleting the two C:\Users\xxx\AppData\*\Thunderbird folders. Where else can it be stored? Could it be Windows registry file?

Thank you in advance.

It seems that ever since my Thunderbird auto-updated to 128.5.1, sending messages with attachments is VERY slow. I just sent a client an email with a 6.9 MB attachment and it took over 2 minutes to send. A few weeks ago, that would have gotten sent in seconds. I tried cleaning out my Inbox and Sent box by moving most of the messages to local folders, but no change. Any thoughts? Anyone else having this issue?

The HTML isn't displaying properly here. Is there a setting to do this in the threaded view?

Also, is there a setting to be able to click on these "threaded" snippets to expand them to the whole message? Thanks!

I am trying to set up a shared calendar that all the employees in my office can access and add to on their own computers, but I am having trouble doing so. Ideally, I would like this on our network to be easily used. At some point, we will also need to be able to access it on our cell phones. How do we do this?

Bonjour,

Mes messageries étant bloquées j'ai suivi le conseil de supprimer mes comptes. A présent je ne peux pas entrer de nouveaux mots de passe et les messageries ne fonctionnent plus.

Hi iam using thunderbird for sooooo many years maybe 15 i dont remember. BUT lately it makes me crazy. If i am trying to fing some email i am using search area in the top of the app. And it will find nothing. Even if i know there is email from person who i am searching for. I will type just few letters or half od the email name and it will find nothning. To be able to find email i have to go online google mail web and search over there.

Why is it like this?

I have tried to install Thunderbird multiple times on my Windows 11 PC. Everytime I try to import my Outlook files it locks up at 33%. How can i resolve this issue? Thank you.

Dear Team,

I hope this message finds you well.

I am experiencing a significant slowdown in email synchronization in Thunderbird. Emails take a noticeably long time to appear after clicking, and the overall syncing process is extremely slow across all folders.

The problem began on Friday, December 6th, following my use of the "Repair" button on the Inbox (8.9GB) and Sent (10.7GB) folders. After initiating the repair for the Sent folder, synchronization across all folders (Inbox, Sent, Spam, etc.) slowed down considerably.

Already done: Checked "All Mail" on Google IMAP: The folder does not appear in IMAP. Troubleshoot Mode: Attempted, but it did not resolve the issue. Reinstalled Thunderbird: Uninstalled and reinstalled Thunderbird on my Mac, but the problem persists.

The issue seems isolated to Thunderbird and does not impact my Mac’s overall performance, memory usage, or speed. The synchronization delay affects only Thunderbird, while other applications function normally. I would greatly appreciate your guidance on how to resolve this issue and restore normal synchronization performance.

Thank you in advance for your support!

Hello,

my old laptop SSD crashed and I had to re-install Thunderbird. It took a few days to do so, in this time I switched from Windows 10 to Linux Mint.

After an import of a (luckily fresh) backup into the new Thunderbird installation, it don't receive messages between 02. December 2024 and 10. December 2024. I can find them via Webmailer (strato.de), but if I click on "Receive new mails" in Thunderbird, there are "no new messages" in its oppinion.

But it is possible to send me a new Mail to the given address, that will be received immediatly.

What can I do to get these E-Mails of the given date range?

Regards Tim
