In the process of changing from Windows to Linux, I have entered the details of my email account and it is fine when I press re-test, but when I press done it is not fine anymore. The email is “freeuk.com” which is still active but Freeuk itself isn’t, but the service was taken over by Claranet with a “clara.net” setting, so I imagine that may be relevant. Any help (not too technical please) would be appreciated. Thanks.

Environment:

• Thunderbird 153.0.2 (aarch64)
• MacBook Air, M4, Tahoe 26.5.1

When I try to create or rename an Inbox subfolder in Thunderbird it all seems’’ to work (no error message), but after pressing “Rename” or Create” nothing happens.

Thought I found a workaround: Created a “Temporary” subfolder in “Local Folders” and “moved it" to the Inbox. And it showed up there. (But it was still in the “Local Folders”!). Tried moving a (Spam) email into the Temporary folder under the Local Folders, that worked. Tried moving a (Spam) email into the Temporary folder under the Inbox—it just disappeared! It was no longer in the Spam folder, but did not end up in (either) Temporary folder.

How can i get new messages in a thread to move the thread to the top? (I have descending order selected) I miss new incoming replies when they sorted weeks or months ago by the original email date.

I have used Thunderbird with the same email account for years, creating subfolders and moving emails to the subfolders with no issues.

With Thunderbird 153.0.1, after creating a new subfolder in the account, when attempting to move emails to the new folder, I receive the following error:

"Thunderbird: The current command did not succeed. The email server responded: APPEND invalid flag list"

I am not able to receive or send emails using my wifi, but can using data (same provider). I have queried this with my email host and wifi provider and both have said there is no issue on their end that would block these actions. The email host suggested I change port 465 to 587 for outgoing to see if that made a difference. It did not.

This issue is occurring on the web platform as well as the android app.

The error message in account setting is: an error occurred connecting to gsyd1001.siteground.net:993."

Mail notifications remains on the home screen and need to be removed manually. I had expected them to be removed after reading the mail or marking it as read. A notification summary with the number of received mails instead of a notification for each mail, as an option, would have been nice. /Sten

Since upgrading to Thunderbird Meadow 153.0 and 153.0.1 when I click on show remote content it opens new tabs in Firefox 153.0. and 153.0.1. The remote content does not appear in the email. Depending on the amount of remote content results in the number of new opened tabs. I have restarted both Firefox and Thunderbird without any differences in the outcome. I did not change any of the settings upgrading to version 153.0 and as far as I can remember I have not changed any settings in 20 years.

I get USA TODAY Daily Briefing by email every day. For some time it's been duplicating stories and ads in the same message. This does not happen with my iPhone. I have used AI to try to fix the problem but to no avail. Any suggestions for how to fix?

I apologize for the subject line, but there is no better way to describe the problem....

I've been using Thunderbird for a few months now and it has mostly worked well. Then this afternoon I was reading my mail in the Unified Inbox and I noticed something very odd. I had a number of emails showing in the header list with the same "From" and various subject lines. On the face of it, that wouldn't describe any weird behavior except that I noticed the subject lines absolutely didn't match the "From" information.

As I would go to read these emails, the email itself would be correct in the preview pane -- including showing the correct sender name and email -- but the "From" information in the header list pane would still be wrong.

I'm sorry that I can't post a screenshot to make this more clear because there is just too much personal information on screen. But these emails are from several different senders, received by several different email accounts. Everything is correct except that the "From" shown in the header pane is wrong. This is very obvious to me because I normally run entirely in the Unified Inbox with the emails sorted by the "From" information

One example is an email that is actually from "U.S. Department of Veterans Affairs <do-not-reply@notifications.va.gov>" which Thunderbird displays correctly in the preview pane (where I usually read my emails) and if I open the email itself, but the header pane says this email is From "Prepper-co <joshua@prepper-co.com>"

Another example is an email that is actually from "USPS Customer Support <uspscustomersupport@usps.gov>" but the header pane says it is from "Rainier Arms <sales@rainierarms.com" < p></sales@rainierarms.com">

These two examples were received in different email accounts that aren't even on the same server. I have other emails from these same senders that are shown correctly

I found this problem while using 150.0 (64-bit), which said 150.0.1 was available, so I restarted Thunderbird and it updated to 150.0.1 (64-bit) but the problem is the same.

I have been shifting my email platform from Comcast to the new Yahoo platform. This has worked for my iPhone and for my Thunderbird app on my iMac. But NOTHING works for this on my MacBook Air. My gmail is fine, but the only way I can get to my new Yahoo platform is to sign in via the web browser. Thunderbird will not configure for the MacBook Air, and I've tried 10-15 different things already (not an expert by any means). I have all the proper settings. I have reinstalled Thunderbird on the latter machine.

I can see that there has been a reply or a messages was forwarded and when I right click for the menu "Open" may not even appear at times. When it does appear "Open in Conversation" is not always presented as an option even though there has clearly been conversation as I can locate reply's in the Sent folder. Sometimes it's there but when selected it opens a tab that only shows the email and none of the conversations. It's hit and miss and I can find no rhyme or reason. Any help would be greatly appreciated. Also, I would love to Testflight Thunderbird on Apple. Thanks, Sue

In recent update several duplicate folders were installed in three different email accounts. Point to them there was a 'delete' button enabling elimination of duplicates. However, on two accounts, 'Drafts' duplicates didn't have the delete button enabling elimination. How to clean up?

I put emails from my Inbox into the delete box. After a while I delete these but I have just found that they remail in the All Mail Box. How do I delete these emails from my acccount on Thunderbird? They do appear in my online Gmail account as far as I can see.

Within the past day or so, which means 7-18-26 or later, some of my email messages on thunderbird for my pc have a "From" description that is not correct. I look at the messages, and the "From" is entirely different than the "From" description when looking at the email message list. I have never encountered this problem before. I'm using thunderbird 152.0.1 64-bit on my pc.

Hello,

I would like to report what appears to be a bug in Thunderbird for Android.

I use a POP3 account with the following settings:

POP3 Port 995 SSL/TLS

The same account works correctly in Thunderbird for Windows.

The problem only occurs in Thunderbird for Android.

What happens:

New emails arrive and are initially displayed in Thunderbird for Android. After the next synchronization, some messages disappear from the Inbox. The messages are not deleted from the server because they are still visible in Thunderbird for Windows. I also tested the same POP3 account in Samsung Email on the same Android phone. Samsung Email continues to show the messages correctly while Thunderbird for Android no longer shows them.

Troubleshooting already performed:

Reinstalled Thunderbird for Android. Removed and added the account again. Tested on both my Android phone and Android tablet. The same problem occurs on both devices.

Is this a known issue with POP3 accounts, or is there another setting I should check?

Thank you very much for your help.

Best regards, Diana
