My Trash folder is filling up with folders that won't go when I "empty" trash. Instead it creates a new copy "folder(2)" when I try to delete the folder. My trash folder is becoming a hige tree of useless folders..... I would dearly like to bring back version 102 instead of the buggy "Supernova" with its ugly interface.....

Thunderbird crashes regularly. I have determined that it might be due to RAM. When Quickbooks is open, Thunderbird will crash almost all the time. If I close QB, it is fine. I have an HP desktop w/ 8GB ram. What I don't understand is that it started doing this recently, but never used to crash. Is TB using more ram now since the latest releases? Any insight would be appreciated.

I updated to latest version of Thunderbird 102.14.0 on 4th August and thereafter all emails being sent by me are being blacklisted by spamhaus.

When i put in a request to Whitelist, it changes for some time and again all mails sent from my inbox are getting blacklisted. The message which i get is as under:

"Your IP address is either exhibiting suspect behavior, is misconfigured, or has a poor sending reputation.

As a result, the IP is listed in the CSS Blocklist (CSS)

Click on Show Details to see if you can request a delisting from this blocklist. This will also display any further information we have relating to this listing."

We have checked with our internet service provider, my email server works perfect. We have checked with ISP there is no problem there too as my colleague uses same network but different mail (outlook) works perfectly.

Please help as I am unable to use Thunderbird for sending emails. While I can receive emails.

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).

Open thunderbird up and want to print an email. Most of the time the printer is the default. Once I print and then go to the next email to print, the default printer is gone and the only option is save to PDF. I can close thunderbird and reopen it and seems to alleviate the issue for a few times then back save to PDF only. Strange issue. I have reinstalled thunderbird a few times. All other programs on the pc I print from always use the defaut printer.

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?

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! :)

Dear reciever. After years of using TB and what we do think is a productive mail-tool that works for the benefits we are looking for has worked. However, the last 115- constantly freezing and shuts down. This is very annoying. It freezes at some folders from the main email-client- as we have deleted older folders integrated with this. But the problems remains. . We have done everything in our knowledge of the program but still no approvement. . At this point we are using Outlook..would be grateful to have some answers and possible sollutions for this issue. . Thanks in advance and keep up the great work U are doing. :-)

We are running Thunderbird Supernova 115.3.3 (64-bit). Update installed about a week ago. Since then, it takes about 45 seconds to a minute for any email message to send. This is happening on multiple computers. Any advice to speed it up again?

I've always left Thunderbird open in the background all day as I'm sure many people do but since the upgrade to 115.3.3 after about an hour Thunderbird freezes and displays "Not Responding".

I'm running the latest version of Windows 11 fully patched and updated.

Is anyone else having the same experience and/or has anyone found a solution?

Many thanks

Mike

I need help to organize the folder structure that was messed up during update to Thunderbird 115. Most urgent is one inbox folder which is now found under the accounts folder and not in the general inbox folder with all the other inbox folders. I would like to beable to move this misplaced inbox folder to it's original place in the general inbox folder.

Also in this misplaced inbox folder, its has other folders in it: template, draft, sent etc. These folder should stay in the accounts folder.

I hope that a future update will clear the mess, and other solutions are welcome :-)

version 115.4.1 table view. cant resize the FAR RIGHT column no matter what. instead of moving to right and DEcreasing in size, its INcreasing the size of the column on the left..

New install on a friend's HP laptop. Thunderbird was setup with profile imported from older laptop running Windows 10. Printer is an HP Smart Tank Plus 655.

Printing works fine on other apps such as Word, browsers, notepad, Acrobat. Start up Thunderbird and can successfully print one document, but subsequent attempts at printing from Tbird show 'Print as PDF' and no other print options in the print dialog box. Attempting to print via other apps produces same result.

Restarting print spooler works temporarily. Other fixes found on forums such as the 'remove addons.json from profile folder' fix dont work.

Have also reinstalled Thunderbird, checked spooler settings, reinstalled printer drivers, with no resolution. Interestingly, I installed Thunderbird on another windows 11 laptop, with a new profile and following Thunderbird's email account setup wizard and I have no printing issues.

Could this be related to importing the old profile across to Windows 11? Or are there other issues at play?

Thanks.

We get our email through GoDaddy, hosted on Outlook. For years we have accessed this email through Thunderbird, but about a month ago we were kicked off and have not been able to sign-in or download any new emails through Thunderbird. We are able to sign onto Outlook through the browser with our passwords no problem, but using the same emails on Thunderbird gives us the attached error message. We have tried uninstalling and reinstalling without success.

Hi all,

Just upgraded to Thunderbird 115(from the last Non beta version).

I have multiple email accounts.

When I click to the inbox off one of my gmail accounts it does not display to the last message received. Thunderbird opens to a message about 1/4 up into my inbox.

I have a second gmail account and this behavior does not occur.

I'm sure its a easy fix, I just can't figure it out .

I have two Hotmail accounts set up on Thunderbird with different pass words and identical server settings that have both been utterly reliable for many years on TBird. For the last week one of them cannot send. A large window for connecting to the outgoing server opens for a moment and then the email freezes and eventually times out. The other sends normally as do all my other email accounts on TBird. I have no trouble when I use x-notifier neo in any browser, so the problem is just on TBird and not on the Hotmail system.

Hi My problem: My hotmail account will no longer send emails. The error message I get is

 From Microsoft: "We can't sign you in Your browser is currently set to block cookies. You need to allow cookies to use this service."    (NB my Firefox browser cookies is set to 'standard' and the settings had not been changed.  Plus I've tried playing with the settings, makes no difference)
  From Thunderbird: "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."

When? Started on 6 or 7 Oct, At this point, both receive and send failed. Last message was just before a Thunderbird update. We were in France, using hotel internet, which Microsoft hates. (so I didn't try to fix it until we got home).

Other info: However my hotmail address still worked well on my laptop's Outlook; internet login, Thunderbird on another laptop (Win 11, and more recent installation of Tb) and on my phone (Android, FairEmail), ie has not been blocked. My usual laptop is Win 10. All other emails within my Thunderbird are working fine. The outgoing SMTP for hotmail is: smtp://smtp.office365.com (smtp://smtp.office365.com) See image attached.

What since: A forced update of Windows (as rec'd by local techy) restored the receive function and speed, which had become sluggish. Hotmail still can't send. I've logged in and out of my microsoft account online, and have changed my MS password (and therefore that of my hotmail account), plus restarted everything lots of times. No difference. I have not got office365 except what came free with windows. I avoid office/MS apps where possible.

PLUS: Discovered that my Tb profile is humungous, 45gb, of which a fair chunk is this last couple of weeks. Most of it is not visible emails. Any advice ? - can I start a new profile and ditch the old?

                   Help please......................

Thanks Eunice Lord

Activity manager error message: "Unable to connect to your IMAP server. You may have exceeded the maximum number of connections to this server. If so, use the Advanced IMAP Server Settings dialog to reduce the number of cached connections." The message has no data about which (out of my 10 connected) server issues it. May be should add this info to the message?

Supernova presents some annoying omissions. Here's another:

• Previous iterations of Thunderbird included an option in the right click menu that allowed the user to empty the bin / trash with a click of a button. Similarly, an option was made available to clear Spam from its folder.

I'd like to request that these be returned as they made management of one's Thunderbird folders much easier and convenient.
