I was not receiving emails from a Comcast.net email account. I called Best Buy and they used remote access to fix the problem. That fix included deleting and reinstalling the email account. After hanging up with their tech, I notices that dozens of folders and thousands of emails from the last 12 years were gone. I called the Geek Squad back and they could not solve the problem. Are the missing emails still on my computer somewhere? If not, can Comcast recover them? Please help!

I followed the recommended procedure to transfer the TB profile from an older W10 computer to a new W11 computer (both using POP accounts ), via a USB Flash Drive. The folders are all listed on the USB profile copy and observed during the scrolling detailed view while being copied to the new computer. Nevertheless, they are NOT listed in Local Folders on the new profile. Instead, ALL the messages (approx 700 of them!) are presented as UNREAD in the inbox folder. How can I restore the original folder sorting?

I run TBD 140.8.0 esr (64 bit) under Debian 12 Linux. Until recently I could automatically enter a special address from the pertaining addressbook, this does not work anymore. helpfiles do not show a solution thus I am here.

The addressbook is full of addresses however I have to transfer a special address via past and copy into the addressfield of the mail I want to send.

Thanks for a quick answer Jörg Kampmann

Things have suddenly disappeared. My sent file is gone and I have searched and can't find it. Tonight I went to send an email and the tab for doing that is also missing. I tried uninstalling and reinstalling with no success. What's wrong and how do I fix it?

I have followed all the other recommendations with, no luck. I am on Windows 11 and use Eset virus software. Thunderbird is not listed as running it Task Manager, and there is no Profile.lock (think that was what it was called) in the profile directory, and I have deleted the existing profiles and recreated it. I have uninstalled and reinstall Thunderbird, and I have rebooted my computer. I am frustrated and concerned I will loose saved emails and my address book! Help.

'URGENT I can receive emails but cannot send emails. Keep getting them back "undeliverable" but they are to my regular email addresses. I have checked and recheck the format for sending they are correct. This occurred around 2nd April As I am making arrangements for a family member's funeral this is an urgent matter.

Ich benutze Firefox auf zwei Windows 11 Rechnern. Die Version ist auf beiden Rechnern gleich, (149.9 esr 32Bit ) , beide Rechner greifen im Fall des Verfassens einer E-Mails mit Anhängen auf einen gemeinsamen Speicher über LAN zu, seit kurzem gibt es bei einem der beiden Rechner aber beim Anhängen einer Datei an die Mail eine Verzögerung von ca. 5 Sekunden, bevor der Anhang auftaucht, unabhängig von dessen Größe. ( Also auch kleine Pdf´s werden verzögert angezeigt.) Der zweite Rechner hat das Problem nicht, selbst bei grösseren Anhängen. ( Auch sind die Rechner fast bau-und ausstattungsgleich ) Testprogramme auf dem Problem-PC zeigen keine Auffälligkeiten beim Schreiben und Lesen, auch die Internet-Verbindung ist die gleiche... Habe bereits die Einstellungen der Konten und des Programms in beiden Rechnern verglichen, sie sind gleich. Hat jemand eine Idee, woran das liegen kann?

Grüsse, Martin

Can not send emails through RoadRunner Mozilla Thunderbird. Can receive. Can send in Spectrum.net, so email account is working properly. Can send and receive with android phone, just not Mozilla. Can not check for latest updates.

Please help! I have not received emails on thunderbird for a week. I have had to go through my web browser. I received messages that thunderbird is temporarily unavailable. What is the problem? How can I resolve this issue? Thank you very much!!

We have been using the Brother MFC-J6940DW iPrint&Scan Attach to email successfully with Thunderbird. It creates a new email and attaches the scanned item to it. Recently it stopped working. Nothing happens and there is no error message. We have run all Windows updates. We have uninstalled and reinstalled the Brother drivers, uninstalled and reinstalled Thunderbird, downgraded Thunderbird to v 143 and 140 from current 144 version. We have confirmed Thunderbird is default mail app and verified in registry that Mozilla Thunderbird is default in HKEY_CURRENT_USER|Software\Clients\mail > (Default) value = Mozilla Thunderbird and HKEY_LOCAL_MACHINEISOFTWARE\Clients\Mail > (Default) Value = Mozilla Thunderbird. We have made sure the Firewall talks nice to the Brother Utilities and the ports are ok for Public and Private. Brother tech support says as long as we can do a normal scan that it must be Thunderbird or Windows. Does anyone have any thoughts or other troubleshooting ideas? Thanks in advance. -- Sue
