Thunderbird Support Forum

I'm using a VPN on my computer and phone and when I try to connect to the mail server, Thunderbird gives me an error saying that the mail server has disconnected. But when I disconnect from the VPN, everything works. This happens only with one mail server, on the others everything works OK even via VPN.

However, the the mail from this server is coming to my phone (where I use K-9 Mail).

I also tried to connect to the mail server via openssl, with the command "openssl s_client -connect mail.server.net:993 -crlf"

The connection is successful (when I'm on the VPN), but when I enter the command "a LOGIN my.username MYPASSWORD", it gives an error:

a NO [UNAVAILABLE] Maximum number of connections from user+IP exceeded (mail_max_userip_connections=20)

I have set the "Maximum Number of server connections to cache" to 1 in Thunderbird, I have set to check for mail every 12 minutes (it already was 15 minutes on the phone before), and it is still the same.

Any idea how to solve the issue? I am connecting to this server with the same username and from the same (VPN) IP only from my phone and my computer, so I find it really strange that there are more than 20 simultaneous connections...

When I try to send a message from my Thunderbird POP Server account I get:

“Sending of the message failed. The message could not be sent because the connection to Outgoing server (SMTP) webmail.digitalspaceportal.net timed out. Try again.”

Try again never works

Here are my Outgoing Server settings

Description: webmail.digitalspaceportal.net Server Name: webmail.digitalspaceportal.net Port: 1025 Default: 465 Connection Security: SSL/TLS Authenticity Method: Normal Password User Name: jrf.consulting@attglobal.net

I am on a Win 11 laptop running Thunderbird V115.11.0 (64-bit)

Hi everyone,

I'm having trouble with my Thunderbird app (version 115.11.1) on macOS. I'm trying to add my Google accounts, but after I attempt to connect them, I receive the following warning message: "Unable to log in at server. Probably wrong configuration, username or password."

I've checked the configuration multiple times to ensure it's correct. Here are the settings I'm using for Gmail:

Incoming Server (IMAP): Server Name: imap.gmail.com Port: 993 Connection Security: SSL/TLS Authentication Method: OAuth2 Username: [my email address]

Outgoing Server (SMTP): Server Name: smtp.gmail.com Port: 465 Connection Security: SSL/TLS Authentication Method: OAuth2 Username: [my email address]

I've also emptied all saved passwords and allowed cookies from sites without any exceptions. Is the version of Thunderbird I have still incompatible with Gmail? Or is there another issue that I might be missing?

Thanks for your help!

I always use Thunderbird online so no need for offline storage. When I installed Thunderbird, online storage was set on for all accounts. I've since turned this off, but would like to recover the disk space. What Windows folders can I delete? Thanks.

I am using Thunderbird in Windows 11 on an Intel NUC 12 computer. I am using Thunderbird in pop mail for gmail.com and mail.com. I save all important messages daily to Folders in Local Folders. Today I attempted to look for messages in one folder named Family and Friends and found that messages older than 2/14/2024 are missing. I checked other folders and found that they seem OK with messages going back 5 to 10 Years. I tried running repair but nothing changed. Any idea where these files can be? I do have backups of the app data for Thunderbird and am considering to try a prior version but I'm afraid I might lose new saved messages. If I tried to Archive messages, could this be the problem? I have looked in Archive and found very little. Any help would be appreciated. Frank

Please ignore this question. I found my older messages.

There is one correspondent whose emails come in, flash on the screen for a second and then disappear. I find it in Junk. I've got the email addres whitelisted on my provider's filters. How can I intercept this process. It's only the one address. So far. Can I whitelist address on TB? I've got it set to not intercept anyone in my address book and this address is definitely inmy address book.

I was in the middle of generating a long "reply all" to a message and wanted to jump to a new page when it would be printed. I absent-mindedly hit Ctl-Shift-Enter and the entire window disappeared and there was nothing in Drafts! Ctl-V just restores the last thing I added to this very long reply! I had been working on this for 90 minutes, doesn't Thunderbird continually update Drafts while working on a long email?

Hi,I have 4 email address & my Default Email is ismda3@westvic.com.au(on SMTP) Regardless which email I TRY to REply to.I receive the Samr Message See attachment I am getting very desperate Thanks Darryl

Hi Windows 10 64bits - Thunderbird 115.11.1 (but same happens with Linux Mint 21.3 Cinnamon). It is the 1st time I ask in this forum, so I hope I respect the rules... "Sometimes", in my e-mail "imapmail" sub-folders, "some" files with an added "-1" appear ("draft-1", "sent-1" , ...). They are always newer (modification date) than the file without the "-1". What are they ? Why create a "-1" that consumes space, and not over-write the existing files ? Is there a parameter somewhere in TB to avoid this behaviour (I closed TB, deleted them, but they "sometimes" reappear when I reopen TB ) ? Thanks in advance

installed Ubuntu 2404 on my acer laptop along with Thunderbird, added gmail email to Thunderbird and it fails to connect to google for their security check.

popup when trying to login to google to let Thunderbird access gmail.

400. That’s an error.

The server cannot process the request because it is malformed. It should not be retried. That’s all we know.

I think the linux Thunderbird is broken.

I have been through this google process with Thunderbird 3 times windows 10 and 11 and once on an android phone with no problems

Norton 360 updated last night and now Thunderbird isn't working.

I tried logging in to Thunderbird but it kept saying my certificate was wrong and refusing to check my emails. I tried to click "add exception" but it didn't help.

It also kept saying its own homepage was a security risk and blocking it.

I figured it was Nortons new update, but have no idea how to fix it. I turned off Nortons Email Protection, which didn't help. So I uninstalled Thunderbird and reinstalled it.

But now its saying it cannot login to the outlook server when I try to add an email account. I know the information is correct, all I can guess is that Norton is blocking it somehow?

Any idea on how I can fix this?

I want to Change date order (ascending/descending) of messages when there are no headings for mail including the date column. How do I do this? I recently installed latest version of Thunderbird.

Good morning Windows 10, TB 115.11.0 32 bit. Multiple email accounts, some gmail, others like sfr, lol and free. All accounts use POP. All working before weekend, shut down the PC. Monday morning, opened Windows, all seems there except TB which has a screen with an Account Setup tab inviting me to set up an existing email address. Close that tab and the attached screen image appears, open tabs blank, no accounts pane on the left, no emails, no local folders. Nuffin. Restart TB and Windows, twice, still Nuffin. Look in Profiles, yes, under Mail all profiles appear to be present and the correct size. Going to gmail’s on line email system shews account open and receiving email normally. I had a problem a month ago after a TB update when all accounts were present but no emails were displayed. I changed the password to 0auth and recovered my emails. That took three days to resolve and I lost a business client through the delay in responding. Today I must file several court documents or I shall be in deep poo. Any suggestions how to recover the left hand accounts pane and see the accounts and folders will earn my undying gratitude.

My unreliable memory tells me I asked this community a question about Thunderbird. I haven't received anything that might suggest someone has replied, and I cannot remember the title I gave that post, so how do I search for it?

Just in case, my 'missing' question was (or should have been) why when I open Thunderbird does it open showing the emails that I received maybe a month ago, not the most recent ones. The most recent ones are there on the list, but I have to scroll down to get to them, which is a nuisance as I have to do it every time I go into Thunderbird

My thanks to you

Hi Really need some help please.

Running TB latest version 115.11.0 on Win 10. Multiple gmail and other accounts, both POP and IMAP.

Following a catastrophic loss of accounts and messages, I made a fresh TB install then I restored from a previously saved profile from a month ago.

Accounts and folders with messages all now appear.

With one POP gmail account, the inbox and sent folders are stuck at last month's position. I expected the last month's messages to be downloaded as soon as I log into TB, but I'm not able to Get Messages.

My TB log in to collect gmail messages is rejected with this message - The STAT command did not succeed. Error getting message number and sizes. Mail server pop.gmail.com responded: [AUTH] Invalid credentials.

I have checked the account settings server address, and password is set to 0Auth2.

I have changed the gmail password on the gmail website (browser is Firefox) - which is accessed without problem, but only incoming mails are visible, my outgoing mails should be on my PC.

Every time I get the "enter new password" dialog I enter the password that gets me into gmail's on-line website - it is rejected with the STAT message.

I cannot send or receive gmail messages through TB - how can I force gmail to let TB access my emails?

I recently changed webhosts, which requires me to change the incoming and outgoing server names. When I change the name and reboot, the server name always reverts to the previous server name. How do I correct this?

Hi,

Thunderbird is not threading messages properly. It only seem to go one level deep ...

This is what it shows: aaa ..bbb ..ccc ..ddd ..xxx ..yyy

Where it should be: aaa ..bbb ....ccc ......ddd ..xxx ....yyy

I cannot find a way to fix that.

Help please.
