My recollection is that prior to a recent automatic update to Thunderbird 140.12.1esr (64-bit) when I had a message composition window open, there were "SEND" button and possibly a "SEND LATER" button (to the left of the addressee and cc addresses in addition to the keyboard shortcuts (CTRL ENTER and CTRL SHIFT ENTER).

Following the update, there is no longer anything to the left of the addressee information. I have checked the toolbar menus, and there do not appear to be any button options. I can still send messages, but the lack of the buttons is a hindrance.

My ISP changed us to another mail provider. So I created a new version of my existing email with different server settings, then restored my email backup. I did this all offline and it was successful. All my emails and folders were there.

Next, I went online to download new email, after which all of the messages and folders from the backup were removed (overwritten). I've tried repeating the process by removing the new account and reinstalling it, but I can't get my old emails and folders back. This is a significant problem because I have over a decade of financial and legal emails in the backup. I have tried a number of the solutions posted in the Community but have not been successful in getting my emails back. I'm using Windows 10 and Thunderbird 115.10.1.

Any insights are most appreciated.

I was attempting to import the calendar info from my old system to my new one, but the export/import of a .ics file did not work. It complained about information not being found. Then I tried copying the local.sqlite database file from my old system to the new one, that initially did not appear to work either :( Come to find out that the database cal_id fields did not match between my new system and the old one, so even though the local.sqlite file I copied had all of the calendar information, the prefs.js file on my new system was referring to a different cal_id. So I used a text editor to replace all of the cal_id's in the prefs.js file, with the cal_id found in the copied local.sqlite file, and now I have all of my calendar data available on my new system. You might want to make this know to your users, since my original searches on your support site did not present a solution that worked. :(

Using Thunderbird for my mail. ATT Yahoo is my provided. My ATT password is not allowing me to get my mail. I keep getting a message to re enter my password. Password does allow me to sign in to my att account.

I have been using Thunderbird for 20+ years, maybe as many as 30. Forever. I have moved my profile across several versions of Windows and multiple computers. There are files in the root of the profile with a modified date of 2009. There may be older ones in sub-directories. There are 18 folders and 125 files. I suspect a lot of this is clutter left over from earlier versions of Thunderbird. In the Mail folder alone there are several hundred files and folders excluding the WDSEML files and actual emails.

I'm toying with the idea of starting fresh with a clean install of Thunderbird and getting on the correct release channel but I don't want to bring along what appear to be hundreds or thousands of unused files and folders.

I there anyone that can identify what profile files and folders to keep and what can be deleted?

Thanks for your consideration.

I'm using Thunderbird 152.0a1 (2026-04-22) on Windows 10 64 bit. When I click the "Get Messages" button or File > Get New Messages for > [my e-mail account] nothing happens. The only way I've found to check for messages manually is by closing and re-opening the program.

Lorsque j'essaie d'ajouter un nouveau compte, la configuration est trouvé dans la base de données des FAI de Mozilla, je clic sur "continuer", dans la fenêtre Popup j'autorise Thunderbird a accéder à mes informations, ensuite j'ai le message "erreur d'authentification". Pourtant mon mot de passe est correcte.
