Thunderbird Community Forum

I have 4 email account using Thunderbird. These are all domain imap email accounts. They work via the web hosting mail (Yahoo/Turbify). I can access many different ways: Outlook on my iPhone and iPads, Thunderbird on my desktop Mac Pro. There was some sort of tech issue at Turbify where all 4 account are hosted but all email was restored and password were reset.

However, only one account jeff@jeffmunk.com no longer work on Thunderbird, perhaps the most import one. I checked both the imap settings and smtp setting and the authentication and recommended ports and I still can't get that one account to work - but only on Thunderbird. It works retrieving from mail from Yahoo and Outlook, both phone apps or a browser on the desktop. I think I has this issue once before.

Hi,

I have experienced a worrying problem since a few days on Thunderbird client (Windows).

I recently received anonymous emails on my ISP mailbox. The sender has been disguised with display name of some of my recent recipients, but the sender is not visible when I open the message. The mail subject is also taken up from these recent emails. Each of these emails contains one of my personal family photos! These suspicious messages are only visible on Thunderbird 128.2.0esr (64 bits) Windows and not on web mail in a browser nor on the mail client of my smartphone!

Inspection of the message source in Thunderbird does not show the email header... but only the binary code of the image that has been included as an attachment.

It appears these incoming messages were modified locally in Thunderbird because I can see the original and valid emails from the senders in a web browser or from my smartphone. I suspect a malware is corrupting some inbox messages in Thunderbird. Norton did not detect any malware on my PC. Malwarebytes has quarantined a few PUPs/MUPs.

Only one of my mailboxes is affected by this problem. Is there any known vulnerability in Thunderbird similar to this report? How can I block this kind of alteration of incoming mail?

It used to be when I moved from just my laptop to my much larger monitor the layout pane sizes adjusted proportionately. Now for some reason the message pane remains at whatever it was on the last device. Is there a way to change that?

I have problems with my folder structure after renaming mail folders. I'm using TB115.15.0 on Ubuntu 22.04, my uni is using outlook as a mail service config'ed with OAuth2. In settings->server->advanced, I have ticked the "show only subscribed" and "server supports folders" options.

A week ago, I have renamed folders, e.g. 3-class-2023-24-this to 4-class-2023-24-last using TB. The structure/renaming shows up correctly when viewing with the outlook web client.

But the old folder 3-class with its content still shows up in grey/italics. In the 'subscibe' menu, I can unsubscribe and submit. But no change in the folder presentation, and when I re-open subscribe, I'm shown this old folder still with a tick as being subscribed to. Similarly for the renamed: It is show as subscribed to at top level, but none of its subfolders. Subscribing to them makes no change, i.e. no subfolders added in the folder structure, and a subsequent subscribe view shows no change in their subscription status, still opens without a tick.

I've seen a lot of posts about ghost folders, with the issue being server side. However asking MS to fix their outlook server protocols for TB seems futile. And our IT service does not officially support TB. This is an annual change-over, and I even tried the brute force delete/add the mail account, but TB has remembered the username ans still gives me the same defective structure in the subscribe window, but now only shows the Inbox. I see no means of making the other folders visible.

Any solutions? Thanks, Jens

Thunderbird stuck on "sending message" Tried troubleshooting mode - no effect. Can use Gmail via browser with same settings Re-started Windows (7), cleared Thunderbird cache - still stuck. No SMPT settings changed Problem only started yesterday

I have Nebula 128.2.0esr (64-bit) for Windows 10.

On the same day of my last Thunderbird update, a mysterious folder appeared in the root of my C-drive with Chinese (?) characters.

The Folder name is: u馐㕈ʶ

(See the screenshots below.)

Inside the folder appears two items:

A Subfolder called: IDB and a file called: .metadata-v2

Inside the IDB Folder, I see these things:

Folder: 3647222921wleabcEoxlt-eengsairo.files and these files: 3647222921wleabcEoxlt-eengsairo.sqlite 3647222921wleabcEoxlt-eengsairo.sqlite-shm 3647222921wleabcEoxlt-eengsairo.sqlite-wal

Inside this folder: 3647222921wleabcEoxlt-eengsairo.files I see:

a folder called: journals and a file named 21 and 22

Inside the journals folder is empty.

Does anyone have ANY idea what this Chinese Character folder is?

Googling it, I see that it could have something to do with Firefox, but I don't use Firefox much and this folder appeared on the same day my Thunderbird updated.

Trendmicro Housecall, Windows Defender, HP Wolf Security -- NONE of them flagged these as suspicious, but I just don't like this mysterious folder on my C-Drive and wonder where it came from and what function it serves.

Thank you!

I moved several messages to a folder called "Teamskeet", but when I opened that folder it didn't display any messages.*** Through tiral-and-error I discovered that the "Toggle message threads" option would show me the messages in that folder.

  The upoaded image display is annotated to explain my question better. Specifically, are the messages that are displayed ONLY the ones in that folder that are threaded? And what does it mean that 15 messages are selected. I didn't knowingly select any  messages.

*** Initially, it didn't show any messages, but after I closed and re-opened TB it did show the messages in that folder. I'll be doing some troubleshooting to re-create that scenario.

Thanks for your help, SweetTasha

I have used Thunderbird for quite a while so finally sent a donation. Withing a few months, my emails won't send. Sometimes they won't receive either. I went to Comcast and asked for help and they gave me a new password for one email address and it worked for a few days now NOTHING. I'm so frustrated! I don't believe it has anything to do with Thunderbird but since Comcast is no help, I'm desperate. I have 4 email addresses and each is important to have access to. Please help me. Linda Collison van der Veur SillySam@comcast.net LatonHigh@comcast.net TahoeDocTom@comcast.net kissincousin@comcast.net

I can receive emails but cannot send them I get a message that says the outgoing server (SMTP) hacksaw-mail.internode.on.net failed Please check your Outgoing server SMTP settings Could you please assist in providing the correct settings so I can check Thankyou Warwick Hack

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.

When importing my contacts from my android phone (Samsung with Android 14) as a .vcf file, Thunderbird import the file but only shows the contacts from 1 group ( I have organized my contacts in my phone by groups, Business, Family, Friends, etc), the rest are shown as dots icons with no data in it, in this case, all my Business make it to Thunderbird but the other groups are ignored. I have also added this .vcf file to My Contacts in Windows and they can be accessed in and individual or list format in the File Explorer. Thunderbird should be able to read this folder with no need for imports. Appreciate any comments in this matter.

i tried system restore. didnt work. tried reinstall didnt work. this happened several months ago and the only was to fix it was using my backup drive. what is causing this???

I have a saved search for unread emails and for flagged emails.

I move incoming emails to sub folders and as I occasionally update the list of sub folders this means that I need to then update the properties of these saved searches to add the new folders into the folders to search list.

Recently I have noticed that when I try to edit the folders to search list it no longer shows the folder list - only the parent email address. (the existing number of chosen folders is still given - so the search still does work for the previous folder list its just that it cant be updated)

This issue occurs with all existing saved searches and also occurs if I try to create a new saved search

Any Ideas how this can be resolved ?

Why is my program stuck on "send later"? I see no way to change it to "send". How do I get thunderbird to send a message, not "send later" with no indication of how or when to send it?

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

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
