Thunderbird-Hilfeforum

At 15:00 yesterday, my Thunderbird was updated (behind my back).

From that moment it could not communicate with my imap server and I cannot renew my account with the server.

I now have to use webmail.

Can I please go back to the immediate predecessor as that has worked well.

I have observed this behavior for a number of releases - currently running 115.4.2 (32-bit). TB doesn't seem to download, or at least process, a graphic within an email until I actually open it. The display can take what seems like a while. I have a relatively fast (deskside) system, lots of memory/disc, GB ethernet, and would like all graphics to be processed when the email is first downloaded instead of waiting. I don't see any setting to change this. Any suggestions appreciated.

My thunderbird email is linked to my Virgin media email. Suddenly Thunderbird has stopped working, so cant send or receive messages. Any ideas - the virgin email is working fine.

cant send or recieve eemails for past week get this message???? This message could not be sent because The connection to outgoing server (SMTP) smtp.gmail.com timed out ... Try again ???

I hae no idea why or what to do now if someone could help me that would be great

Sorry I have no idea what any of what is in the Shared Data means

Hi, we started getting Thunderbird errors on both inbound and outbound messages when everything was fine earlier this morning on both. We are on Windows 10 running the Thunderbird 115.5.0 (32-bit) Release.

Inbound error message: The STAT command did not succeed. Error getting message number and sizes. Mail server inbound.att.net responded: [SYS/TEMP] Server error - Please try again later. Outbound error message: Sending of the message failed. The message could not be sent because the connection to Outgoing server (SMTP) outbound.att.net was lost in the middle of the transaction. Try again.

Are you all experiencing server issues - I don't believe this is a configuration problem on my side?

When I use a html signature with graphics, the recipients who can not receive Html, do ot receive the grafics, obviously, but also not any other attachment like a PDF file. The same is sent but not received! in other words, our customer complain that we forgot the attachment, but we did not. If I resend without the signature, they receive the PDF file. If I reply with an attachment and have a previous signature with grafics in the feed, the attachement also disapears. The only solution is no grphics in the signature, but that is not a solution, just a quick fix. Thank you very much for your replies.

I have just switched to Thunderbird from Gmail. Have tried several times to send bulk emails but always get this message:

Sending of the message failed. An error occurred while sending mail. The mail server responded: We have detected an unusual amount of suspicious mail originating from this address. Please try again later.. Please check the message and try again.

I have a need to send emails frequently to more than one address and this is going to be most inconvenient if it can't be fixed. Is there a setting somewhere?

Thank you.

I have faced with the following bug linked to messages displaying in thread in any section of Thunderbird (i.e., Incoming messages). See the screenshot - there is just thin white stripe instead of text of the message. This bug repeats only for some random messages. Restart of Thunderbird resolves this bug temporarily.

Was just updated to version 115.5.1, and I had held off posting this question until after the update, hoping the issue might be resolved... but it's as bad as ever.

Tbird abruptly became very slow to delete/display messages; not with the last update, but a couple of updates previously. I have been in the habit of working my way up the list from the oldest to the newest, and as I hit "delete" and "up arrow" to view the next email, it's a slow, laggy process. Both emails remain highlighted for a second or two, the old email continues to display, then the deleted email drops out, and shortly the new one displays, the whole process taking a bit over two seconds... to move from one email to the next, a process that used to be nearly instantaneous. No idea exactly when that changed, but it seems to be a process that's getting worse with time.

Any ideas on what I might be able to do to get my original level of performance back? For what it's worth, this is a new machine, insanely fast compared to my older one, and Tbird is the only app where I'm encountering this kind of slowness issue. Everything else is astonishingly faster by comparison... but Tbird remains laggy and slow and I've no idea where to start looking for reasons for this. Don't even know what kind of information to post here that might be useful in diagnosing the issue - - tell me what's needed and I'll do my best to get it. Thanks in advance! I *really* don't want to change email clients after all this time!

After years without problems, Thunderbird suddenly started locking up when I try to insert an image into a new message. There is no error alert; the message just completely locks so that I have to force task to end. Until a couple of weeks ago, I was able to insert files stored on my computer or copied from browser with no problem at all. [Not talking about a signature, just an image. Emojis work fine]

Am not aware of changing anything. Running Windows 11 Home version 23H2, if that helps anyone explain what's happening. Thunderbird version 115.5.0 (64-bit)

Haven't tried un/reinstalling TBird as want first to see if there's an easier solution (have several accounts).

I am using Thunderbird v 115.5.1 on a Windows 10 system. I am using an "@hotmail.com" email address. I seem to be able to receive emails just fine, but face an issue sending out emails. When I press "send", it gets stuck on "sending message" for quite a while, then I see the error message:

=

Sending of the message failed. The message could not be sent because the connection to Outgoing server (SMTP) smtp.office365.com timed out. Try again.

=

My SMTP settings: Server Name: smtp.office365.com Port: 587 Connection Security: STARTTLS Authentication Method: OAuth2

Appreciate any help! :)

On Nov28 changed to Rel 115.5.1, my thunderbird can receive messages but can not send. I am getting an error message saying that my password is in error. However when i go to Mail.aol,com my password works fine. again this just started on the 28th.

Email that I am sending from Thunderbird is being rejected for no apparent reason by the recipient server. This is not due to an ISP or sending server security issue since, when I send exactly the same email from my ISP email web page (not Thunderbird) the email is received properly and accepted without error. So, the problem is most definitely with Thunderbird. The following is the header text from one of the rejection replies.

Do not reply that his is an issue with my ISP. It is not. It is purely a Thunderbird issue. Thanks for your time.

Hi everyone! Apologies upfront in case this question has already been asked, but I'm struggling to see if something similar was already posted... In a nutshell: I delete messages in my inbox (or any other folder) in Thunderbird, but when I login to the website of my mail provider (gmx.net) or check the app on my phone, I still see these mails on the imap server. Is this a known issue? What could be the reason?

After many years of use, the delete button has stopped working. Moving any email into the deleted folder of local folders works, but I would prefer to have the delete button back.

Hi. I'm using T-bird v 115.3.2, and since the upgrade to 115, I've been seeing weird behavior regarding opening messages vs their getting marked read.

I'm referring to actually opening the message in a new window (I do not use the preview window--it is turned off).

My usual reading behavior is to open a message, read it, then press <F> to go to the next message. In either case, most messages immediately get marked as read. However, some random messages do not get marked as read immediately--after a delay, the message gets marked as read. It seems to be related to messages from some specific senders, as opposed to random messages. For example, marketing messages from Southwest Airlines always seem to have this issue, as do the daily newsletters from "The Hustle."

What are the criteria for T-bird to think a message has been read? If it matters, I'm seeing this on mailboxes where I use IMAP access. I have not seen it occur in the mailbox where I use POP3 access, but almost all of those messages are plain text.

This morning I suddenly could not send emails from Thunderbird. I contacted my ISP (Plusnet) and they demonstarted that if I used webmail I could send emails and they concluded there was a problem with thunderbird. They suggested removing my account and re-inputting it - which I did. Not only did this not answer the problem but all my folders to which I have moved messages have all disappeared. This is a huge problem for me. Are they all in the cloud? is there anyway I can retrieve them?
