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."

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.

Storage always full with only 100 or so e mails in my in box No junk or spam or anything else No one else in the company has this problem but me and my storage is getting smaller and smaller . I do more e mails then anyone but am always full with less than 200 e mails

Hi - I created folders for important emails and placed them in there over the past few years. The folders remain but the emails have all disappeared. I'm hoping its an easy retrieval.

Hello all,

Apologies if this is going over old ground. I've tried the usual Repair Folder fix without success and I'm cautious about trying anything further without some expert input for fear of doing more damage.

Thunderbird version: 140.12.1esr (64-bit) Windows version: 11 Server type: POP, messages not left on server Inbox " Folder properties" reports: 16384 messages. 13.8GB on disk

The Entire contents of Inbox disappeared after the following sequence of actions: 1. Tagging a selection of messages (in Inbox). 2. Making only those tagged messages visible (using Quick Filter). 3. Selecting all of the visible messages (select first, shift-select last). 4. Deleting the selected messages (Del key) The intended messages were successfully moved to the Deleted folder.

The Inbox now appeared empty. At this point only tagged messages were set to be visible but these had been deleted so an empty Inbox pane seemed correct. Resetting the tags visibility of Quick Filter did not make the messages reappear.

The messages are however visible and openable when doing either a straight folder search or when using a search folder. Inbox Folder Properties reports that the messages are still present and the reported size on disk seems appropriate for the number of messages.

Messages in all of the other folders are visible.

At this point I did a complete Export of the profile. When I discovered that Windows would not recognise the resulting .zip file I also did a straight copy of the Inbox file within the profile folder to a safe location (I understand that the export .zip file is intended for re-import to Thunderbird and that Windows might not recognise it).

I then did a Repair Folder (within Folder Properties dialogue). This made no difference although the size of the Inbox.msf file reduced dramatically (I didn't make a note of the before and after sizes).

I then quit and restarted Thunderbird several times. This at first made no difference. After perhaps 3 or 4 restarts however a relatively small number of files have reappeared in Inbox (a tiny percentage of the correct total). Curiously, most of these (but not all) are marked as spam. Ordinarily I would delete all messages marked as spam but there are probably some that I have missed. It looks rather as if the files which are now visible in Inbox are ALL of the spam messages plus a handful of others. Of the 172 messages which are now visible they were initially correctly reported in the folder pane as being 172 unread messages.

Another strange thing is that when selecting the Inbox on the folder pane, the small number of messages which become visible only appear after a delay of perhaps 10 seconds (previously this was instantaneous). When selecting any other folder, the messages are displayed instantly.

I'm not quite sure what best to do next. I haven't yet tried deleting the Inbox.msf file. Any wisdom will be gratefully received.

Thanks in advance.

Hi

Just checking when ThunderMail and Pro will be available? I'm in need of email services for my small business and just don't want to subscribe to Google. I love Thunderbird, glad it survived so many transformations over decades and would like my subscription contribute to further development.

Can you, please provide me with at least estimated timeline?

Thank you S

Had one account. Imported perfectly. Added another, only Inbox and Trash added (later Drafts when I composed a new email)

Where are all the account folders ?

Thunderbird used to have a small counter which showed the progress of moving emails from one folder to another. Really useful when moving emails into local folders. Could you please restore this in an update -- or is there an add-on?
