Thunderbird Community Forum

Some months ago I received an email, but the body of the email was a picture (jpg) from my computer. The sender definitely does not have the image. The content from the sender is missing, and my image is in the body of the email and as an attachment.

This has happened a handful of times over the past 6-9 months, with the same image showing up in emails from various unrelated senders.

I just received an email from my partner who sent me an email with a screenshot attached, but instead of receiving what he sent, I've got an email with my image that randomly shows up in my inbox.

A few days ago it happened, but when I restarted my computer, the unwanted image was no longer present, and the actual email content was visible.

Restarting my computer has not resolved this particular instance.

Does anyone know why Thunderbird is in love with this one image of mine and why it keeps showing up in my inbox in emails from other people?

After successfully downloading Thunderbird several times (my browser is Firefox), the only functioning option provided is to make a donation. That is, it's telling me I must make at least a $5 donation in order to proceed to setting up a Thunderbird account. This despite clear statements on the website that donations are not required in order to use Thunderbird. There is no way to skip this step.

After closing the donate window, I'm taken to a nearly-blank screen with absolutely no functioning features on it other than a link that leads to multiple, useless articles about who knows what.

Please fix the site and advise how to proceed without further roadblocks.

My Thunderbird will not connect to the Comcast/Xfinity email account with the same settings that Outlook connected to and downloaded all my emails and my inbox structure. I believe this is either a battle between Comcast and Thunderbird or a big glitch in this application, My Gmail, Outlook365, work fine in Thunderbird, not Comcast. This started about a week ago. Has anyone found a solution?

I have uploaded an image of my view of the email client. As you can see, there are two columns under the red arrows. I have made them appear through a menu accessible by three dots. Somehow, I have lost that menu but touching the wrong choice and I would like to be able to access it again so that I can remove the two colums indicating the number of emails and their weight. Can you help me to retrieve that menu?

I recently downloaded Thunderbird. (I used Thunderbird in my older computer. It was fine) Now I can receive post (joram@internet.is) but I can´t send post. Why is that?

Recently I notice if I forward an email to someone or I send an email with an attachement it is failing. Sometime I get a bounce email hours after or none at all

What am I doing wrong?

I have my calendar from mailbox.org synchronized with my thunderbird via CardDav/CalDav. I have multiple calendars in the same account (e.g. work, free time, brithdays, ...). I cannot change in which calendar an event is saved after I created it.

How to reproduce: Edit an allready existing event and change its calendar (e.g. from "free time" to my "work" calendar).

Expected behaviour: The edited event is now moved to the other calendar.

Observed behaviour: The event is not moved (any other changes to the event are saved though).

It is not the fault of my provider as it works on my phone and on their web app.

This is either a bug in any of two ways:

• It does not change calendars events but it should.
• You are not supposed to be able to change the calendar afterwards and that means the selection of the calendars should be grayed out/ give you no option to save it.

(I know I can Ctrl+X and Ctrl+V it into a diffferent calendar, which I use at moment but that costs additional time.)

Thanks for any help with this :)

PS: I have to choose a topic but the calendar is not even part of that list. What is going on there?

I have been moving slowly from other email clients to Thunderbird. I've been using Thunderbird in Windows for a while now, and decided recently to switch on Android from BlueMail to Thunderbird for Android.

In Thunderbird for Windows, I am able to use unified folders for all common folders (Spam, Sent, Trash, etc.). On Thunderbird for Android, however, only the Inbox is presented as a unified folder. I have discovered that this limitation is really problematic for me for two reasons.

First, if I am in the unified Inbox and accidentally delete a message, I have to check several different Trash folders to find the lost message, selecting each account and then that account's Trash. I anticipate responses asking why or how I could delete a message and not know what it was. With the avalanche of incoming mail the days, I often would use swipe to delete on the unified Inbox for items that are clearly not important-- but occasionally, a real message appears on the face to be junk and isn't. This is a real hassle, and forced me to turn off the swipe to delete a message interaction altogether, because it was too easy to lose messages.

Second, I have several different email addresses, and several different email providers, each of whom applies spam and trash rules differently. Two in particular frequently divert legitimate email into Spam, and I had been in the habit of scanning Spam for errant valid messages from these two providers. Being able to do this for all Spam in one location made this process much simpler.

Can anyone tell me:

• whether there is some underlying reason for this different behavior on Android,
• whether there are plans to implement such a change, or
• whether there are alternatives (like BetterBird, which does not have an Android port) that I could use?

I have two accounts hooked to thunderbird, my work account that uses google workspace and my personal gmail account. Today, my work account went totally crazy, and it's loading emails in my inbox at a snails pace. Meanwhile, my personal gmail account loads fine. I did literally everything. I deleted and restored the accounts, then I deleted the Thunderbird app and all the library folders on my mac that had thunderbird (maybe I missed some?) Then I reinstalled Thunderbird and connected everything again. Same result. Personal Gmail imap works great. Work gmail with google workspace is incredibly slow and won't load in my inbox.

Before reinstalling i did everything, cleared cache, compacted folders, changed to not have messages stored locally. What could I be doing? Is google workspace imap having trouble?

I installed the latest Thunderbird version last week, is this a version update problem? After a full reinstall of everything, I'm totally confused now. I've gone through my settings 10 times and spent 8 hours on this today. I used chatgpt to guide me and try different things. I'm stumped, please help. I'm a donor that supports Thunderbird!!! I've used it since 2008. 147.0.1 (aarch64) Release notes

I stopped using Thunderbird in 2024 because of inability to change pw. I have same email accounts at comcast but would like to go back to Thunderbird. Currently using Comcast directly but loved TBird. I have a pw in use at comcast , how do I get Tbird to accept it for both email accounts on iphone and ios laptop?

I use thunderbird in conjunction with Firefox. Lately thunderbird will freeze. Mouse and all button work but cannot like read a email, delete a email ect. Any thoughts? Go to task manager and end task and all good. But its getting like 3 times in a 1-4 hour period now.

On my PC Thunderbirds sending/receiving mail says the mail server refused my connection. My laptop works fine. I have duplicated my laptops in/out specifications onto the PC but still nothing works. Spectrum says everything on their end is fine but can't vouch for roadrunner who is the rr in my mail address of ca.rr.com. All this started about 4 days ago. Any ideas on what to try next? Thanks.

I am trying to set up the latest version on Thunderbird on my wife's old Gateway (WIN 7 home premium). The previous version of TB has problems so I deleted it and am starting over. I have manually configured this TB with the server info from the TB accounts on our other computers, but get the error as stated above. What do I need to check?

Hi, I recently installed Thunderbird (POP account type), but it only downloaded about 3000 emails and then stopped, even though I have a lot more emails I would like to archive. It's been about 2 days since no more downloads have occurred. Ive got no way of knowing if it's a temporary pause or what the issue is.

I installed Thunderbird to archive my emails as I intend to delete some older emails from google work space to clear up space, but I want to still have an offline archive of these email.

Something changed, but I don't know what. I can not receive nor send emails on my PC Spectrum email account. I can receive and send them on my iPhone and iPad. I've changed the configurations, but no luck. I'm using the password saved on my iPhone to log into Spectrum/Charter.net Any suggestions? Thank you!

This is what I get when I click on email link. I can't delete it. This has to be solved before I can get to my second problem https://webmail.spectrum.net/mail? context_token=eyJza3NpZCI6ImNvbnRleHRfdG9rZW5fc2lnbl9rZXlzZXQiLCJza2lkIjoiNmJkYzZiMTEtZjBiZS00ZGFlLTliOWUtY2RkMGMyNWE5ZmUyXzIwMjAtMDEtMjRUMDcuNDIuNDQuMzQwWiIsInNlY3BvbCI6ImNvbnRleHRfdG9rZW4iLCJraWQiOiI2YmRjNmIxMS1mMGJlLTRkYWUtOWI5ZS1jZGQwYzI1YTlmZTJfMjAyMC0wMS0yNFQwNy40Mi40NC4zNDBaIiwia2V5VHlwZSI6IlJTQSIsImFsZyI6IlJTMjU2IiwianRpIjoiYWU2MzMwZDYtNTBlZi00Mjk3LThlOTMtZDUxOWVjZmMxMjdkIn0.eyJzdWIiOiI5RTJGNzAxQi02N0IyLTRBQkYtODA3Ni00RkUzRUIxMzdBRkQiLCJkZXZpY2VfaWQiOiI2NTUzMDYyOS01YWJmLTQ0MWQtYTE1OS04Njc3ZDc0ZTU1NzUiLCJzZWNwb2wiOiJjb250ZXh0X3Rva2VuIiwiaXNzIjoiY29udGV4dF90b2tlbi1pc3N1ZXIiLCJpZGVudGl0eV9ndWlkIjoiOUUyRjcwMUItNjdCMi00QUJGLTgwNzYtNEZFM0VCMTM3QUZEIiwicHJlZmVycmVkX3VzZXJuYW1lIjoiampmbHlubjUwQHR3Yy5jb20iLCJub25jZSI6IjE0NjY2MTM2NzYzODIwMzY5Mzk2NDMwMzI1ODQzMiIsImNsaWVudF9pZCI6ImNvbnN1bWVyX3BvcnRhbCIsImF1ZCI6ImNvbnRleHRfdG9rZW4tYXVkaWVuY2UiLCJhdXRoX21ldGhvZCI6IlBhc3N3b3JkIiwibmJmIjoxNzY5ODc5NzgwLCJhdXRobl9zb3VyY2VfcG9ydCI6IjU5ODc1IiwiZ3JhbnRfdHlwZSI6ImF1dGhfY29kZSIsImRsYV9wZWVyX2p0aSI6ImFjNTZmMGEzLTg0OGMtNDNhOS1hOTUyLWNlNzllNDM4YmI5MiIsInRydXN0ZWRfY2xpZW50IjpmYWxzZSwiYXV0aF90aW1lIjoiMTc2OTg3OTc4MCIsImF1dGhuX3RyYWZmaWNfb3JpZ2luX2lkIjoiNjguMTcyLjE2OC4yNyIsImRsYV9wZWVyX2V4cCI6IjE3Njk5NjYxODAiLCJleHAiOjE3Njk5NjYyNDAsImlhdCI6MTc2OTg3OTc4MCwianRpIjoiYWU2MzMwZDYtNTBlZi00Mjk3LThlOTMtZDUxOWVjZmMxMjdkIiwiYXBpX2d3X2RldmljZV9pZCI6IjY1NTMwNjI5LTVhYmYtNDQxZC1hMTU5LTg2NzdkNzRlNTU3NSIsImlzQ29udGV4dFRva2VuVFRMT3ZlcnJpZGUiOnRydWV9.SkxhnFtRLxHTpXXn5_kDX8nBISuPu3wdpoNFwTKLtmUadL29D40rNMHlmEOOa2LbGFVi8qlEWnscUMV8WXGLF02RFhSsEMFtBbXGpB9XUy6q_YW5FRJo1su5AJxboh1LMastJ39rdqnooQsnvA5_Mmy4NDBZrb1bQCmzXn3wiLsiBDMxorQ8Kk45CEWL6Bz09Z8EltuEQ2yVN3FGTGqAeU2i5-qNv12kzgimIu4TbDyE2DIi6_AKenLGc1kXlcZ8oxGjUEbJm1AThmpNbGF9WJ7d55_JQyfGWvEMIYNOtAiPaNNRCF1AlcBP3TAH34L1uI49Ve6C0SvidbRu2jYDuQ&referrerAppVisitId=202601311716P-753ab3c2-c22c-44cd-865d-2b77307fabfa&referrerAppName=SpecNet&referrerAppType=Web

I have Mozilla Thunderbird and I find that some emails particularly with attachments (but not always) disappear from my inbox after a few months and I can't find them by doing a search under the sender's name or in my inbox.

As an example my most important emails come from 2 sources. One is an accountancy practice and the other a property management company. Those from the accountancy practice are nearly always missing after a few months but those from the management company rarely are.

If I carry out a search on the accountancy practice name, nearly all of the emails in the list are ones that I have sent and the only way I can find a particular email is to look at the trail before my email, but by doing so there are no attachments with their email. If I then look at the date of their email in the trail and then search for the date in my inbox, the email isn't there.

Added/Created this folder " " 0 _2026 - BANKS - 5 CARS [ 2 NEW/3USED ] "

Now the folder looks like this

         0 _2026 - BANKS - 5 CARS  [ 2 NEWe96f7068

I have a dozen other folders that appear like this with the letters/numbers at the end. When I delete them they reappear next time I open Thunderbird.

Are these folders corrupt? 
How do I eliminate them ?  
How do I stop folders from reappearing?

Thanks,Mike
