Thunderbird Support Forum

Title. Thunderbird is a really cool client but it's pretty slow. I blame that on the thousands upon thousands of emails that my hotmail and gmail each hold. I don't necessarily want to delete these emails, but I have seldom a reason to have any email older than 2 months in my thunderbird client slowing and crashing the program whenever I want to combine inboxes.

To this end I went to "Synchronization & Storage" and told it to "Synchronize the most recent 2 months" but it didn't delete the huge cluster of older emails. The next option is to tell TB to delete these emails in the same menu but as I understand it that would also delete them in the server, which I don't want to do for posteriority.

What do I do?

This is the message I get when trying to send emails: "Sending of the message failed. An error occurred while sending mail. The mail server responded: pgbentley101@gmail.com recipient rejected. Please check the message recipient "pgbentley101@gmail.com" and try again."

Over the past two weeks Thunderbird has been constantly stopping without any notification, just goes to sleep and will not wake up. Have to restart the app to get it working, works for a while, then goes back to sleep. Really, really a pain. I am considering something else if this keeps up, every time I restart it windows takes information about the problem but does nothing to fix it. If you're going to beg for money, maybe you should make it work first?

Can you please help me make it stop downloading my entire inboxes randomly. I've put up with this for years because my research has failed to find the right answer. It took an hour to download 5000 emails I already had over and over and over make it stop.

When I try to add a hyperlink to a picture, then the editor freezes.

I think this happend since an thunderbird update.

Can you tell me, how to fix this problem, or can you recommend me a former stable version?

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.

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.

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.

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

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.

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.

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!

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.

Thunderbird will not open. the error message is: "Thunderbird is already running, but is not responding. The old Thunderbird process must be closed to open a new window." Pressed the "Close Thunderbird" button, but no response. Checked Task Manager and ended the Thunderbird application...still no change. Uninstalled Thunderbird and downloaded .exe file and installed...still the same error message. Rebooted the computer...still not change. Can you please assist with this problem. Thankyou I

Sending of the message failed. The message could not be sent because connecting to Outgoing server (SMTP) smtp.gmail.com failed. The server may be unavailable or is refusing SMTP connections. Please verify that your Outgoing server (SMTP) settings are correct and try again.

What can I do?

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?

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.
