Thunderbird Community Forum

I occasionally have problems with Thunderbird insisting that posts in my frequently visited newsgroup are expired when they are not. Previouly, I've been able to resolve this problem by simply unsubscribing from the newsgroup and then subscribing again. But today, when I tried that technique, Thunderbird told me that there were no messages at all in my newsgroup. This is flat-out wrong because the newsgroup is quite active. Right-clicking and choosing Get Messages did NOT change the situation.

Then, to add an extra layer of aggravation, I added a second newsgroup to my subscriptions, one for Thunderbird itself, but it was empty. I deleted that folder and then unsubscribed to my other newsgroup and tried to subscribe again but now the "Manage subscriptions" button shows me no newsgroups whatsoever!

I am beyond frustrated by this nonsense. What do I need to do to get "Manage subscriptions" to show me the thousands of newsgroups that exist and how do I make "Get messages" to show me the messages currently on my newsgroup?

I'm using Eternal September to access Usenet. My operating system is Windows 10. The version of Thunderbird I'm using is 128.8.1esr (32-bit).

Some messages do not appear in Inbox, and can not found by Filter (Ctrl-Shift-k). However, when I use Search (Ctrl - k): 1) They are found and 2) the Location is given as ... Inbox. These are recent messages.

How do I know they are there? I occasionally use a Webmail interface to access the account that Thunderbird is linked to and all messages are there. Also, when I get chided by others for not responding to their emails, I go looking.

I have tried Properties | Repair Folder on the Inbox.

Account | Synchronization and Storage settings are:

    Keep messages in All Folders on this Computer
    Synchronize all messages locally regardless of age 
    Don't delete any messages
    Always keep starred messages

Thank you for your consideration and suggestions.

In one account the Trash folder is a subfolder of Inbox. I do not know how that happened. It is the "official" Trash folder; the icon is unique and I cannot delete it.

There is a regular folder named "Trash" that appears to be linked (shadowed?) to the real Trash folder.

How do I move that subfolder ("Trash") to the top level, equal with the Inbox?

I see an icon that an email I received has an attachment but there is no longer any sort of visible attachment to click on and open. That has disappeared since my last updating 128.8.1esr (64bit)

As email threads become lengthy they become unreadable. The older emails turn into displaying one character per line. Is this a bug or something fixable on my end?

I use an AOL email account and Thunderbird on my Mac. In Thunderbird, the junk mail folder - which AOL call "Bulk Mail" for some reason - has moved to the Trash folder and I can't get it out. It's a Thunderbird problem - if I go onto my account at AOL.com, everything is normal. How do I get it out? I've tried cutting and pasting it, creating a new folder...nothing seems to work. I don't want to empty the trash in case I no longer have a junk folder at all

Relating to Thunderbird. Two email accounts, Gmail and Spectrum's "mail.twc.com", required setting up with Thunderbird. Gmail was no problem with immediate success. "mail.twc.com" was another matter. This particular account is setup and working on 3 Apple devices under IOS yet Thunderbird will not allow 'sign in' during 'texardvark@twc.com' - using SAME settings. Web searches reveal settings that should work however they don't correspond to options provided during Thunderbird setup. In particular, there is a log-in failure using same login credentials as IOS.

This problem is not earthshaking as I can use TWC Webmail w/o any problems, just not through Thunderbird. I'm primarily providing this information toward your development efforts. I used Thunderbird with Linux and was pleased. Thought I'd give it a try on PC Windows 11.

Boy did I find something useful, then I ran head first into a brick wall.

I found this nice article about integrating google calendar (link to article here), but I need more detailed info on what to input for the Username and what to input for the Location.

I tried my full gmail, so "johndoe@gmail.com", is that what I use for the username? Or is it "johndoe"?

For the location, do I input "calendar.google.com" or something else??

I've tried it a few ways, and it just has the blue thinking circle next to "Please wait while your calendars are being discovered." but nothing ever happens.

Issues solved. "Provider for Google Calendar" required a log in to Google. I was already logged in and hence I didn't take notice. When I finally did, the issues were solved.

Since a couple of days I have the follwing 2 problems: 1. I can't update my google calendar from TB and changes made in the android doesn't show in TB 2. The message moving function doesn't work. Messages disappear from the inbox but wont show in the folders where they should have been moved to.

I have TB 128.8.1esr(32-bit)

I have Yandex Calendar enabled on a Windows computer using CalDAV in two applications - Thunderbird and OneCalendar. On an android phone, Yandex Calendar is enabled in the Yandex Calendar app.

Android App <--> [Yandex] <--> Thunderbird Calendar (Windows)

                                            <--> OneCalendar (Windows)

When I create an event in the Yandex Calendar app for Android, they are visible in the calendar web interface, they are visible in OneCalendar on a Windows computer, but not visible in the Thunderbird calendar on a Windows computer. All other events created in the apps and web interface are visible in the Thunderbird calendar. All CalDAV connection settings in Thunderbird and OneCalendar are the same

I would be very grateful for any advice to solve this problem.

The emails received and marked as junk mail do not automatically get placed in the junk folder. I would like clarification as to how this works. I want to have items marked as junk and/or spam removed from the inbox and placed in the appropriate folder automatically.

I just did a clean install of mint 22.1. Before I did that I wanted to export my address book. The only option I had was to export to Thunderbird mobile and I downloaded TB mobile to my android Tablet. Now I have a clean install and I need to have my address book back. I have searched high and low on your support pages, Reddit, and others. The only thing that comes close is from your support page that doesn't answer the question as it is circular. how to export to mobile and then import to mobile. How do I import the K9s file my TB mobile exports into my TB desktop? Thank you for your time James Maule

Good evening

I download the Google takeout document from my Gmail. I installed the Thunderbird and intalled the addon importexport.

I imported the Google takeout document to Thunderbird. I can see the email list.

When i click one of the emails, there is no preview. When i double click one of the emails, I got a new window. And when the window opened, i have nothing.

Not sure where is wrong.

Thank you

Every 2 to 3 weeks the Thunderbird Calendar gets wiped out, ie all entries deleted. Once it occurred right after an update. A few hours later it will reappear. Why does this happen and what's the remedy to stop this?

I'm looking for an email solution for my husband and Thunderbird looks promising. However I'd really appreciate input from this community regarding our specific scenario before I make a move. I have a programming background but I fumble blindly trying to be his email admin.

The problem we are trying to solve is his current email setup chokes on send/receive almost daily, after which he has to use Task Manager to kill a hanging Outlook.exe process. After years of tinkering I'm about to give up on Outlook completely. I think the main issue is how Outlook interacts with his Archive. His Archive.pst file is 4GB and Outlook saves it as one big file even though it has many subfolders which are essentially his filing system. Outlook is configured to save everything directly to a local laptop which is backed up regularly and we want to retain this local feature. Thunderbird is attractive because: 1. it supports the local drive storage 2. it appears to have options for transferring his Outlook archive and other folders over in such a way that he can continue to search and access them as needed. He would also like to be able to: 1. move new emails received in Thunderbird into the same (transferred) archive subfolders he has now 2. send and receive new emails without the program choking 3. view and send new emails from his Android phone (without accessing the archive) 4. transfer his email contacts from Outlook and manage them in Thunderbird Can anyone see red flags with this in Thunderbird? He does NOT use:

- Outlook Calendar (we synch our phone calendars to Google calendar online)
- Outlook Tasks

Technical Details (in case it matters):

- HP Pavilion 2021 laptop running Windows 10 with 1TB storage (200+ GB free) and 16GB RAM
- Likely to upgrade to a newer bigger laptop with Windows 11 this year
- Outlook is running from a Microsoft 365 subscription
- His actual email account is from gmail but is named per a domain name I purchased
- His Outlook account is setup using IMAP
- We use ESET for virus protection and NordVPN for WIFI security

Any comments or advice are greatly appreciated!

I recently changed my password for Spectrum e-mail and setup my Thunderbird e-mail with the new password, and when I try to get messages on Thunderbird it asks for the password, goes through the login procedure then then returns with the error message "Login to server mail.twc.com with username tppm.ca.rr.com failed." with "retry", "enter new password", and "cancel" buttons.

I currently am using Thunderbird Version 128.8.1esr, Mac OS 15.3.2 As of 3/21/25 no new emails. I have two other accounts in Thunderbird that were not affected. I am now getting the following failure message. Anybody else having new messages not showing up since then? Tom

4 days ago, the calendar app suddenly stopped working. If I try to add an event, it sends an error message saying 'An error occurred when writing to the calendar Sandra Kanfer Clarke! Please see below for more information.' and tells me 'modification_failed' and that 'If you're seeing this message after snoozing or dismissing a reminder and this is for a calendar you do not want to add or edit events for, you can mark this calendar as read-only to avoid such experience in future. To do so, get to the calendar properties by right-clicking on this calendar in the list in the calendar or task view.' At this point, the calendar switches itself to 'read only' and I get the exclamation mark and triangle saying this calendar is momentarily not available. This is a synced Google Calendar that has been running on Thunderbird for several years without any problems. I uninstalled the calendar and reinstalled it, I uninstalled Thunderbird and reinstalled it - none of it makes any difference.
