I am transferring thunderbird to a new computer. I copied the Thunderbird profile from the old computer to the new computer but most of the old messages are not showing up. I uninstalled thunderbird from the new computer and reinstalled it and again copied the old profile but still the old messages are not there. How can I get them on the new computer?

I'm not sure what to call the different parts of the compose-message window, so please look at the attached screenshot. I'd like to relocate some of the buttons from the top right corner to the lower left, below where the formatting buttons are. Is there a way to do so?

Hi, I am running a windows 10 with Thunderbird version 157.0.1 (64bit) IMAP version. I am having problems with quite a few of my old messages not wanting to open when I click on them. This is the message that pops up (Server mail.daystar.io has disconnected. The server may have gone down or there may be a network problem.) mail.daystar.io is my carrier.

My Thunderbird connected to my gmail is running slow. Thunderbird is not running slow on my other (non-gmail) account. It takes 10-15 seconds for an e-mail (from gmail) to be deleted or moved within Thunderbird. I have tried "compacting folders" and "repairing folders" and that does not help. Please help!

This morning I started getting this popup in lower right part of my screen every minute :

Mozilla ESR Thunderbird Connection to server inbound.att.net has been reset

It continues over and over as TB tries to get new messages.

Also, AVG Free antivirus is telling me it has identified a site certification problem. LOCATION: inbound.att.net (POP) Process: thunderbird.exe Detected by: Email Shield

In TB Help it says I'm currently on the esr uipdate channel .....whatever that means Whats the issue here? Can anyone help?

Attaching files no longer works in the current version of Thunderbird—what should I do now?

Das anhängen von Dateien in der aktuellen Thunderbird-Version funktioniert nicht mehr, und nun?

Since the recent update, 157.1, I cannot get the "Get Messages" button to work and it will not download new emails. I can download a previous version and it works just fine. I also cannot stop the auto updating function even though I check the box to not auto install.

Hello at all, I manage several email addresses through Thunderbird Version 153.4.Oesr (64-Bit). For a few days now, it has not been possible to send emails with attachments. When I click the attachment button, nothing happens. Does anyone have an idea what might be causing this. Thanks for your support :-)

Bonjour, Sitot la version 150.0.1 installée automatiquement, je ne peux plus ajouter de pièces jointes. Merci de debugger

I can't get an attachment to an email message. When I select the 'attach' button, nothing happens. I recently cloned my C: drive and am concerned that something didn't get cloned properly

Thunderbird update to 156.0.1. After 2 days, it stopped accessing my email account. Get Messages does does not bring up password screen. Have confirmed that server settings are correct per ISP requirements. Thunderbird loads OK. Can see and access my previously downloaded emails. However, can NOT access email server for any new emails. No idea what to do or where to go. As is, Thunderbird is a useless program.

When I attempt to send email I get the following message: Sending of the message failed. The message was not sent due to exceeding the allowed number of recipients. The server responded: Policy-SC01 You’ve reached your sending limit. Don’t worry, you can send again soon..
