Thunderbird Support Forum

I have been using Thunderbird since the demise of Eudora. My configuration file is messed up and I would like to clean it up without losing everything. I have many accounts on different platforms. My unified inbox no longer works. It was working for my gmail accounts, but now nothing shows up in it. When looking through some accounts, there were multiple copies of emails in the archive file, and I never put them there.

Is there some way to preserve things like signature files and personalities and sever configurations, and set up thunderbird like a new install preserving the above and my contacts? It is a real mess now. I think there are multiple configuration files and I would like to delete some of them, but am afraid to.

I've gone through most of the questions asked regarding this and have tried to follow all of the directions but none of them work. Let me begin by saying this is the worst time I've ever had at migrating from an old computer to a new computer using TB ever. EVER! This is the worst. I am moving from an ASUS Win11 to a HP Win11 so there shouldn't be that much of a problem. I've done this more than a few times so I know the drill of copying the %appdata% from one place to another. I have installed uninstalled deleted reinstalled, uninstalled reinstalled deleted three times and keep getting the same problem and have been doing this going on three days. I donated to get his copy and am about to ask for my donation back if I don't get a very simple answer. I keep getting that error message no matter what I do. I need a very simple walk through on how to get what I am able to save from the old computer into the new computer without a lot of magic and rain dancing and click here and delete this and see if this sticks. I need a very simple take your profile.zip and unpak it here then open TB and do this. PERIOD. The profile is on the same computer not a server. If I cannot get a quick down and dirty answer please just tell me and I'll ask for my donation back and move to MS outlook and deal with their FU'ed POS. I really don't know why TB has taken a turn for the worst here. But it's not looking good IMHO.

Thunderbird 115 destroyed existing emails in several accounts !!!! Compacting folders removes emails Deleting emails leaves data in the folders etc, etc, etc.......

where can I get a download of the last trouble free flatpack version of Thunderbird

Is there an automatic removal to go back to the previous version

I have multiple nstmp files in a subfolder of IMAPMAIL of TBird 115 using GMail in Windows 115. The files range in size from 170 to 335 megs. Do I need to keep them all, or can some be deleted? On a weekly basis, I do move mails I want to archive from the server to Local Folders and compact the various folders, as well as regularly deleting mail I don't need from the IMAP Inbox. I keep mail in the IMAP Inbox that I need to be able to access from anywhere. It looks like the size of the NSTMP files seems to follow the historical size of the IMAP Inbox. Thanks!

I am using Thunderbird version 115.7.0(64-bit).

The Inbox is 15.5 GB in size as shown in the attached image file,Inbox Size.Jpeg.

The Inbox folder is not displayed as the attached image file,Folders.jpeg, indicates.

Please provide me with a solution to this problem.

Hello,

This is more of a puzzling question. I have been receiving multiple daily notices to Compact the Folders, to save 503MB of space. Even after doing a "Compact" I get another request or pop-up to do it again. I even went to the pull down menu and did a "Compact" from there and again less that an hour later another pop-up!! I have upgraded to the latest version 115.8.0 (64-bit) and the same thing happens.

I know I have an option to make the "Compacting" automatic but I am concerned that it will happen constantly and block me from normal usage at the worst time.

The the question is: What am I missing or what is the solution??

Thanks,

Les

I use Thunderbird for mail.cablespeed.com email accounts as well as a gmail account. The last few days all outgoing messages on the cablespeed accounts do not go, instead I get this error message:

Sending of the message failed. An error occurred while sending mail. The mail server responded: [VO-1] Message blocked due to spam content in the message.. Please check the message and try again.

What is happening? What can I do about it? Tech support (such as it is) from Astound Broadband, the current owner of cablespeed, says that they have ended the use of all 3rd party email clients...without notification. They want me to use their web email. My contacts are on Thunderbird, my email folders are on Thunderbird. What a headache. The gmail account works as it should on Thunderbird.

This is new. What can I do?

Hi, starting with Thunderbird 126.b02 (al least) there are very heavy perfoming issues. Beyond crashes it takes approximatly 10 seconds to open a specific email. Moving to another account is much more difficult: taking itself a much of time it takes supplemental time to open the INBOX.

Despite an Raphael on-dice-graphics I'm running a discrete Radeon RX 6700XT. HDD is far away from being over-lastet or running out of memory

Any ideas? Appreciated. Thx. B.

Thunderbird 125.0 (64 bit)

Hi, Last week, my Thunderbird just stopped showing new incoming mail. I have tried many, many times to get it up and running with my new emails. I am with Telstra as my internet provider, running Windows 11 and Norton360. I am not able to send either. All my folders are OK, and I have not lost any content. I am able to see new emails on my Telstra email but I prefer to have Thunderbird. Please advise what to do. Ryan

Since starting my Win 10 Pro computer today, Thunderbird 115.4.2 (64-bit) has been "dead in the water". When it's launched, it posts the customary "Downloading Message 1 of [N]" status report, but then hangs right there, takes 3 or 4 minutes even to (re-)populate the tabs and panes that had been open, doesn't get past the alleged first new msg even in 15 or 20 minutes. When it does populate the Inbox pane, it shows no messages newer than last night just before shutdown. Very sluggish response to cursor, too: for ex. 30 seconds from clicking on a msg title in the Inbox pane to displaying that msg, even longer to bring up Help/About (with "Not Responding" shown in its title bar.)

  I get my mail through gmail's IMAP server but prefer to use Tbird's interface . Thinking there might be something evil about the first msg that was waiting to be downloaded, I used gmail's web interface to review everything new since last night, deleted several msgs that had attachments, then started Tbird again.  No change.  Can't even get Tbird into the "Work offline" state because it attempts download-of-new-msgs immediately after being started.
  The only consistently effective way I have found to STOP the hung Tbird is through (Classic) Task Manager's "Processes" list, which usually shows five or six "thunderbird.exe" instances.  After selecting whichever has the largest memory allocation I click on "End Process."
  This all "feels like" a bollixed internal state.  Does Tbird store internal-state information in its own file, or is it buried in the Registry?   If I attempt restoration from a backup, which files are needed; or is that unwise?
 I see there is a mid-April update available to 115.10; would installing it reset current messed-up internal state, or will that already messy situation prevent the update?   Is there any risk of losing my Inbox, Sent, etc contents?

Thanks!!!

Using Thunderbird version 115.11.0 (64-bit) with Windows 7 OS and THREADING TURNED OFF.

When I receive a second reply to an email I've sent via one of my email service providers that uses an outlook365 server, my thunderbird view hides it beneath the first reply unless I manually intervene by clicking on the "greater than" sign associated with the first reply. When I do click on the first reply the greater than sign spins clockwise 90 degrees and the second reply appears below the first as if it were in a subdirectory.

The above behaviour is very inconvenient because I am prone to missing the second reply and have trouble anticipating its existence. Admittedly the unread second reply does change the first reply's text property to "bold" but I much prefer to see the new message without having to manually click on everything bold to check.

Another email service provider I use also has an Outlook365 server but second replies to emails are not hidden in its associated thunderbird inbox?

Can anything be done in thunderbird to stop this "feature" or is it absolutely fixed by service providers?

One of my two gmail accouns has suddenly become impossible to access (cannot receive, cannot send). T'Bird produces an Authentication has Failed notification, after a Google Window headed "Sign in to Mozilla Thunderbird Email" which refuses to go away. Clicking on the 'help' or 'privacy' options in that google window produces no more than a blank window but then "Sign in to Mozilla Thunderbird Email" reappears a few minutes later. My other gmail account doesn't have this problem, so I assume it's not gmail but it's T'Bird.

What's going on?

(BTW signing into this Support resulted in an email "New sign-in to Mozilla Support" warning "New sign-in to Mozilla Support to Firefox on Windows 10". Trouble is, I'm on Windows 11. Trivial maybe, but telling maybe.)

I am migrating from Thunderbird to Office 365. I have moved the email by putting the Gmail details into Office 365. However could you please advise how I can migrate Tasks , Calender and Contacts from Thunderbird to Office 365 without having to pay for an Mbox to pst conversion tool.

External request to provide email content and send automatically, such as HTTP GET or POST similar to restAPI to do stuff on thunderbirds application for automated tasks, like opening emails, send email.

Since Thunderbird was upgraded to 115.10.1 (64-bit), it now fails to send SMTP messages with the following error.

Sending of the message failed. The message could not be sent because the connection to Outgoing server (SMTP) ***.mail.pairserver.com was lost in the middle of the transaction. Try again.

This affects all six(6) accounts in Thunderbird, all of them can receive and edit e-mail messages; however, all of them fail to send e-mail messages.

Prior versions of Thunderbird have worked with this configuration for many years.

Other e-mail clients such as Evolution do not have this issue and I have confirmed with my provider that Thunderbird is no longer sending e-mails.

Any thoughts on how to roll back Thunderbird until this issue is resolved?

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

Good day,

I am encountering an issue with opening messages through the global search feature. Despite being able to locate the specific email, clicking on it does not display anything as depicted in Figure #2. I believe the email is stored in one of the folders.

I would greatly appreciate your guidance on how to properly open messages using the global search feature in order to reply based on the original correspondence.

Thank you. May

Hi, just upgrade to Windows1 and did a new installation from Thunderbird. latest version 115.11.0 (32-bits) But the new messages are almost directly market as read even with setting mark messages automatic as read set to no?
