Hi,

noticed some problems with the use of "Customize From Address" when sending out emails:

My configuration does have several free-mailers like GMX and multiple self-owned+self-run domains as well. Each mail account is configured to use their own credentials for Outgoing Server (SMTP). No sharing of SMTP credentials between accounts.

I have used the "Customize From Address" w/o creating an identity with my own domains a few times (the one-off use case, as described by TB). It is working with TB in general for each of my domains.

Now on 2 occasions I realized that sending via "Customize From Address" from customaddress@mydomain1.com ended up being sent to Outgoing SMTP-Server of @mydomain2.com. Therefor failing on submission.

Will try to enable some sort of logging in TB to find out why that is happening - not sure if that will provide enough detail to find out why this is happening.

Are there any recommendations you have or good resources on how the emailaddress of "Customize From Address" is matched with the correct Outgoing SMTP Server?

Thanks starfish

When I open Thunderbird it opens multiple tabs while attempting to get emails from an email folders. It doesn't allow to access any other email folders while trying to get messages from that particular folder and it eventually crushes.

I recently installed Thunderbird on a new installation of Ubuntu 24.04 using the "Installing Thunderbird manually" instructions. Everything works fine except that Thunderbird doesn't want to use the Thunderbird icon in the dock. Thunderbird opens and runs fine when I click on the Thunderbird icon, but it then puts a new default icon on the dock that looks like a gear instead of just "using" the Thunderbird icon to indicate that the application is running. I've attached a screenshot. When I close Thunderbird, the gear icon disappears.

I am running version 128.1.1esr (64-bit) on Windows 11.

A few weeks ago one of my email accounts stopped working so after attempts to find and fix the problem I resorted to deleting and recreating the account in Thunderbird.

The account is a hotmail.co.uk account and the server type is "POP Mail Server".

I noticed that there were fewer folders under the account (Inbox, Drafts, Sent and Trash). There may also have been a Junk folder. I thought that perhaps Thunderbird would create any additional folders as and when messages appeared in them, but I have now discovered that I have messages in the Spam folder on the server but they do not appear in Thunderbird.

Please can someone tell me what I have done wrong and how can I fix it.

Many thanks.

Using TB 115.15. When I move a large number of messages (200 or so) to a sub folder the move goes fast until it gets toward the end, then it locks up until it finishes a few minutes later. When I tried to move over one thousand messages at one time, I let it run overnight, some messages moved, some only moved a date header of some earlier time (all the same time) and all messages were left intact in the original directory. After moving the messages a few at a time, I had to manually delete the duplicate messages in the sub folder. What is the maximum number of messages Thunderbird will move at one time.

Using TB 115.15. When I delete a number of messages, then empty the trash, I cannot delete another message until I restart Thunderbird. Is there a limit as to the number of emails I can trash prior to emptying the trash?

I have had a few emails that did not show up in the inbox listing, so the message count at the top indicated more messages than were listed. Doing a search showed them, and by moving them from the search results to another folder, and then re-searching and moving them back, caused most of them to appear. But not all - I still have a message count of 20, but only 19 listed, see photo 1. Photo 2 shows the hidden email (from Barry Chandler). So the email is there, it's just not visible!

so today i was going through email deleting junk. i would search by keyword then highlight and delete. i had gotten a lot done when i noticed that if i went to read an old email i would click on the email and the page was just white. nothing there. i shut down the app and restarted it and the same. restarted the desktop and the same. i was looking around to find a fix and now almost a year of email is gone. all email from 10-7-23 till now are gone. i have received new email and all works fine. but a lot are gone. any ideas? thanx

I use Thunderbird 128.2.0esr (64-bit) to read mail from the Outlook server; these are the folder mappings:

imap://<email>@outlook.office365.com/INBOX imap://<email>@outlook.office365.com/Sent imap://<email>@outlook.office365.com/Drafts imap://<email>@outlook.office365.com/Trash

I used to also be able to read the Junk Email folder from the Ourlook server the same way, but the folder disappeared from my Thunderbird a couple of months ago. I tried re-adding it as a sub-folder, which is how I created it in the first place, but it won't appear on the list.

I'm not sure what else to do here. I don't know where the Thunderbird directories are stored locally any more, I'm using Ubintu 24.04.

Hello everyone,

I tried to import an ical file and the process failed with the following error message:

Uncaught (in promise) NS_ERROR_XPC_JAVASCRIPT_ERROR_WITH_DETAILS: [JavaScript Error: "Could not extract integer from "--T:"" {file: "resource:///modules/calendar/Ical.jsm" line: 156}]'[JavaScript Error: "Could not extract integer from "--T:"" {file: "resource:///modules/calendar/Ical.jsm" line: 156}]' when calling method: [calIDateTime::nativeTime]
   #setDateParamHelper resource:///modules/calendar/CalStorageItemModel.jsm:1043

   addItem resource:///modules/calendar/CalStorageCachedItemModel.jsm:180
   adoptItem resource:///modules/CalStorageCalendar.jsm:235

2 CalStorageItemModel.jsm:1043

I'm not familiar with javascript, but it seems to me, that the code is trying to import a date timestamp. I noticed, that the ical file uses a format like this: DTSTART;TZID=Europe/Berlin:20241118T180000

I'm not sure, this is the real cause, but I didn't found the string "--T:" in the whole ical file.

Hello, I have recently added an email account to Thunderbird. This is a Microsoft Exchange account. The filing tree within this account has not been imported to Thunderbird (at least not visibly) and I cannot find how to address this. The option to Subscribe folders does not appear to be available. Any assistance would be gratefully received. Thank You, Martin.

Since upgrading to this version the Sender's Email address shows up in a Bold Font in Card View. How do I change it to a normal font unbolded? I've not been able to find the setting? Thank you,

P.S. I'm running Thunderbird also on a Windows computer and this isn't happening.

I'm getting these notifications multiple times a day. It serves no useful purpose, there is no way to stop them, that I can see and no way to universally shut off this type of notification. Please help!

Dear Community I have had an gmail account on thunderbird for years. In/outbox etc details were still on thunderbird but when checking account details in Thunderbird all info was there as normal.... but.. in "View password"..there was no details at all for this gmail account - but were there for other accounts.

Went to the gmail app and tried login...my email and password are correct...login was ok. I deleted the gmail account from thunderbird and tried to to do "New, Email Account." and entered my gmail account details correctly and hit Done when green gmail 'configuration" is "found".

Then I get a google window to sign into my gmail email account - it has correct email address shown.. I enter correct password and get this message.

"400 Thats an error... The server cannot process the request because its malformed. It should not be retried. Thats all we know"

Thunderbird email setup then shows a yellow box that says "wrong configuration... etc"

Checked in gmail settings and imap is ticked - pop is not. Also checked Gmail "Connections to third party apps and services" and Thunderbird was enabled in April 2021.

Does someone have a fix for this?? or... where have I gone wrong?? Cheers M.

Dear Sir or Madam,

I'm using Thunderbird already for a long time and I'm very happy about it. Until now!

Since 1-2 weeks the programme does not download my emails anymore. I have to go to my hosting company and download my emails from my various domains, which is a pain. I read your "solution" in the help section, but it does not help as yet. I don't know what I might have done to change the settings, but when clicking on "Get Messages" no text at the bottom bar apears that it is looking for mail, but only a blue coloured bar at the right bottom on my screen apears and when completed disappears again. When I then go to my host company (Dot5Hosting) I can find my new emails.

What do I need to do to solve this problem? Thank you very much in advance for your solution(s). Kind regards, Ronald Verwer.
