Good morning, I has been using Thunderbird for my email account for several years. For the first time I encountered a problem that Thunderbird seems not to see sub folders I have created on the IMAP server. They suddenly disappeared and when I go to synchronization, the program does not open the list to select folders to download. I tried to restart computer, close and open thunderbird, but nothing seems to help. I will appreciate advice or assistance. Kind regards, anna.

After I did the 128.5.2esr update, none of my email accounts can get email with SSL/TLS on. It won't even try the server with SSL/TLS on. If I turn it off, then it can get mail. When I try to change to STARTTLS it will just hang showing checking server capabilities. Some accounts are imap and some POP3

Running Windows 10, version 22H2 updated 12/10/2024 OS Builds 19044.5247 and 19045.5247

Gmail works fine. I've tried the just about all of the things I have found online, but no luck.

Any suggestions? In the past I rolled back to a working version and that fixed it, but it hasn't worked this time. Would removing all of the certificates fix it? Didn't want to take that chance until I threw it out out here!

Thank you!

I am not getting my email on Thunderbird. I am getting this message: "Could not connect to server pop3.optusnet.com.au; the connection was refused" Could you please help with this? Kind regards, Luke

After updating to 137, trying to send emails times out for my GMX email, however for Gmail it still works fine (I attached the console output in safe mode). I am not using a firewall or a proxy and the problems persists in troubleshoot-mode. I am using Manjaro with Kernel version 5.10.234-2.

1st I am 90 yrs old. Been using this app since it was created. Never a problem until these new updates.

Was trying to delete old file (like the old program (block and hit delete). Found some message about deleting Trash folder and things I did not and do not understand. I now have LOST all my data, emails, addresses, everything.

I tried deleting the program and downloading a new copy. Did not work.

App Will not let me create an account. It keeps searching forever and have to cancel. App can't find my google password and just locks up. I only have two gmail addresses. I can access them by going to gmail.com but all my folders are not there. I need HELP please.

I can't even update my address file at the gmail site as I have no access to anything from TB. I am a research genealogist and now have lost all my saved research information.

What setting do I need to change so that threading does not occur in any of my email folders? I hate this feature and wish to remove it permanently.

Thanks, Steve

On Windows 11 Pro (latest updates) desktop, I use Thunderbird (latest update) to send/receive email. Usually, Norton 360 (latest update) VPN must be turned off to received emails. I say "usually," because sometimes it works with VPN on. Is there a way to receive emails without needing to usually turn off VPN? What I have been trying hasn't worked. Thanks, if you can help.

I have used Thunderbird for years (now on 128.5.2esr (64-bit) for Mac). I have a very large number of folders, and I would like to have a default setting for columns in new folders I create. I am aware that you can change the column setting in the folder by clicking the "Select columns to display" button and selecting the ones you want, and that you can change the setting for all folders in an account by going to the "Apply columns to..." > "Folder and its children..." > select the account > select the account name at the top of the list. But I would rather not have to do that every time I create a new folder, but I can't find any other way to do it anywhere, including on another answer to a question in this forum, https://support.mozilla.org/en-US/questions/1426413.

Then I found two settings in the Config Editor... that seem like they might be where this can be done:

• mailnews.database.global.views.conversation.columns, whose settings in my case are:

{"selectCol":{"visible":false,"ordinal":"1"}, "threadCol":{"visible":true,"ordinal":"3"}, "flaggedCol":{"visible":true,"ordinal":"5"}, "attachmentCol":{"visible":false,"ordinal":"7"}, "subjectCol":{"visible":true,"ordinal":"15"}, "unreadButtonColHeader":{"visible":false,"ordinal":"9"}, "senderCol":{"visible":false,"ordinal":"17"}, "recipientCol":{"visible":false,"ordinal":"19"}, "correspondentCol":{"visible":true,"ordinal":"21"}, "junkStatusCol":{"visible":false,"ordinal":"11"}, "receivedCol":{"visible":false,"ordinal":"23"}, "dateCol":{"visible":true,"ordinal":"25"}, "statusCol":{"visible":false,"ordinal":"27"}, "sizeCol":{"visible":false,"ordinal":"29"}, "tagsCol":{"visible":false,"ordinal":"31"}, "accountCol":{"visible":false,"ordinal":"33"}, "priorityCol":{"visible":false,"ordinal":"35"}, "unreadCol":{"visible":false,"ordinal":"37"}, "totalCol":{"visible":false,"ordinal":"39"}, "locationCol":{"visible":true,"ordinal":"41"}, "idCol":{"visible":false,"ordinal":"43"}, "deleteCol":{"visible":false,"ordinal":"13"}, "xnoteCol":{"visible":false,"ordinal":"1"}}

and

• mailnews.database.global.views.global.columns, whose settings in my case are:

{"selectCol":{"visible":false,"ordinal":0}, "threadCol":{"visible":true,"ordinal":0}, "flaggedCol":{"visible":true,"ordinal":0}, "attachmentCol":{"visible":false,"ordinal":0}, "subjectCol":{"visible":true,"ordinal":0}, "unreadButtonColHeader":{"visible":false,"ordinal":0}, "senderCol":{"visible":true,"ordinal":0}, "recipientCol":{"visible":true,"ordinal":0}, "correspondentCol":{"visible":false,"ordinal":0}, "junkStatusCol":{"visible":false,"ordinal":0}, "dateCol":{"visible":true,"ordinal":0}, "receivedCol":{"visible":false,"ordinal":0}, "statusCol":{"visible":false,"ordinal":0}, "sizeCol":{"visible":false,"ordinal":0}, "tagsCol":{"visible":false,"ordinal":0}, "accountCol":{"visible":false,"ordinal":0}, "priorityCol":{"visible":false,"ordinal":0}, "unreadCol":{"visible":false,"ordinal":0}, "totalCol":{"visible":false,"ordinal":0}, "locationCol":{"visible":true,"ordinal":0}, "idCol":{"visible":false,"ordinal":0}, "deleteCol":{"visible":false,"ordinal":0}}

The first one matches the columns I see in a newly created folder better, having the "xnoteCol" entry, but my new folders also have several columns related to my CardBook extension at the bottom of the list. Moreover, the settings' arguments don't make sense in terms of what I see. For example, I see the Thread column, whose settings – ("threadCol":{"visible":true,"ordinal":"3"} – make sense since "visible" is set to "true", but I also see the Attachments column, whose settings – "attachmentCol":{"visible":false,"ordinal":"7"} – *don't* make sense because "visible" is set to "false". Similar no-sense settings occur in the second setting.

So there *is* a way to change the default column settings in Config Editor..., which makes a whole lot of sense, but the way the settings are set in these two settings, which apparently are not the ones that fully determine my default settings given the CardBook-related columns that I see, do *not* seem to make sense.

The "Folder and its children..." approach works, but it makes it harder than it should be, and it seems like there must be a way to change the defaults in Config Editor.... If there is, please tell me how.

Thanks for any help you can give...

First time using Linux Mint and Thunderbird programs. Very much a Noob

Not able to get a good install from a Google Address book export in .csv format. Reviewed file in spreadsheet and data is there but not importing into Thunderbird Address book.

Your help would be appreciated Ken Davis caravanken@gmail.com

For years I used Thunderbird to process my Earthlink emails. Thunderbird suddenly stopped accepting my Earthlink password, which I repeatedly tried and reset. Is something wrong with my Thunderbird settings? Mac IOS 13.7.1

After Thunderbird just updated to Version 128.5.0esr today, now all my accounts are saying that the connection is refused. This is coming from three different email services that I have accounts on. I'm assuming it's not an issue with those servers as I can access them just fine with a different email client, and I didn't change any settings. Yesterday it worked, today it doesn't. Only thing that seems to have changed is Thunderbird got updated.

I'm using thunderbird for gmail account, and I struggle to mark some events notification as completed when they are deleted using gmail interface. They keep on poping up but when I hit `Dismiss` it gives me this error: ``` Status Code: 2147500037, The request cannot be processed.

Server Replied with 400 If you're seeing this message after snoozing or dismissing a reminder and this is for a calendar you do not want to add or edit events for, you can mark this calendar as read-only to avoid such experience in future. To do so, get to the calendar properties by right-clicking on this calendar in the list in the calendar or task view. ```

I don't want to make my calendar read-only because I'm still gonna use it but I can't remove these annoying pop-ups because of the error. Please help what can I do

Hello, I have a problem with subfolders. I created a few on my account, but they are not visible. When I go to the email application on my phone (samsung email), they are visible. please help me with this problem

RE: Thunderbird 128.2esr Nebula I like to keep things simple and I know I was able to this before (ie: SuperNova), although I can’t remember how. How do I set “PERSONAL Address Book” as my only (default) address book; or how do I eliminate Collected Addresses? I prefer to keep all my contacts in my “PERSONAL Address Book”.

I tried to send an email and got a message saying "The message could not be sent because connections to Outgoing server (SMTP) pop3.gmail,com failed. The server may be unavailable or is refusing SMTP connections. Please verify your Outgoing server(SMTP) are correct and try again". I checked and they seem right but I cannot even send an email from one account to the other. The same message appears and I don't believe anything has been changed, aside from adding another address, that I know of.

Some of my older emails, which were in HTML, now appear as text with full headers and formatting data, making them unreadable. How do I convert them back to HTML?

Thunderbird 128.2.0esr (32-bit)

I FOUND no close TOPIC.

Google calendar allows color-coding of events - but the display is highly inadequate. T-bird 128 calendar apparently HAS no option to color events. But events are FAR easier to see WHEN color-highlighted. Would this be a difficult option??

Message filters not working after transfer to new windows device. (Apologies for long report below). Problem is similar to that reported and still unsolved here: https://support.mozilla.org/en-US/questions/1391209

All old messages automatically accessed under IMAP protocol sit within correct email folder on new device.

Message filters rules successfully located on old device, copied and placed in corresponding windows folder on new device. Email folder structure looks identical on both devices.

New messages sit in inbox on new device, without being filtered. Instead error messages appear, repeatedly.

"The folder 'xxxx' could not be found, so filter(s) associated with this folder will be disabled. Verify that the folder exists, and that filters point to a valid destination folder.

The folder 'yyyy' could not be found, so filter(s) associated with this folder will be disabled. Verify that the folder exists, and that filters point to a valid destination folder.

If same new messages are accessed on old device, they later appear in correct folder on new device, and no longer sit in inbox

How to make email folder structure on new device visible to filter rules there ? This is necessary for filtered email to work successfully on new device, without requiring old device to be operational - it will be taken out of service in near future.
