Already a voluntary donor and satisfied Thunderbird user then I suddenly lost many of my folders and could not recover them, asked for support but got none; nobody interested! As a non-techy older person I expect help when necessary so this has been a sobering event, making me question my continued presence here; very disappointed. John

I had problems connecting with Thunderbird for 24 hours (I connect via an imap server from my Sky account). When this was rectified, email folders which I had created had disappeared. These contain historical emails which I can ill-afford to lose. How do I restore these?

I had all files downloaded from my old PC to an external harddrive and uploaded to a new PC. My Thunderbird account does not appear on the new one. How do I correct this?

Thanks for any help with this.

Hi, After migrating email server, I am having problems synchronizing some IMAP accounts, but Thunderbird is unable to organize the emails and it corrupts the display. In Webmail it is normal and I have no problems accessing it. Coincidence or not, but the emails that are causing this problem are emails that have more than 80Gb. What I did to see if it would improve, was to divide the emails into folders by year, to reduce the size of the email occupancy, but it didn't work. At first, right when I implemented it, they asked to modify this configuration:

Edit → Preferences → Advanced → General → Configuration Editor. Follow the procedure: Locate a key called: mailnews.customDBHeaders Change it to: Received After that restart the application --> Right click on the folder and go to Properties --> Repair Folder

This worked for a few days, but then it started having problems and even repairing the folder, but it didn't help. What they told me was an issue with Thunderbird reading email data on their server, but the problem continued. They kind of "washed" their hands, since it's ok on their server and asked to test it on another email client. Has anyone experienced this problem? Attached is an image of what the email looks like, there are several with the data that I asked to repair, but empty. I've already updated to the latest version of Thunderbird, but it's still like this.

Just Updated to Thunderbird 128.1: Now I Cannot Sort/Move Recipients from TO: to CC: / BCC: and Back on A-Previous Sent (Now New to-be Updated) New Email.... Can I Rollback to Previous 128.0 Version????

Apparently I have changed the Thunderbird account settings causing an alert message on all incoming emails. As shown in the bottom of the example attachment it reads, " The unique identity matching the prom address was not found. The message will be sent using the current from field and settings from identity Bob Poulnot <atldetective@gmail.com>.

Also by opening this incoming email it is showing at the top that it is "From" Bob Poulnot <atldetective@gmail.com> as a reply. I did not click on reply.

Please help. Thank you

Hi, Why do I have to click twice in a row on a message in the trash that I want to delete? This is how I do it: The message is moved to the trash and should be deleted from there. I mark the message in the trash and then click once on Delete at the bottom right. A window appears asking if I really want to delete. I then click once on Delete and neither the window nor the message disappears. Only when I click on Delete a second time do the window and the message disappear from the trash. What could be the reason for this and how can I fix it? Thank you for a useful answer. I don't have much experience with IT and Thunderbird. Regards Manfred

I just got a new computer running windows 11 pro. I downloaded Thunderbird, which I used on my old computer(windows 11), and followed the steps to set up my email. I know my email address and password are correct as well as the server settings and I keep getting the following error "Unable to log in at server. Probably wrong configuration, username or password". My email is .verizon.net which is handled by AOL. My husband also uses Thunderbird and verizon email and I checked the configuration against his computer and everything matches. I was able to get my gmail account added so it must be something with aol or windows 11 pro. Any help is appreciated.

my head is spinning with trying to understand. i changed the authentication to oauth2 but can't seem to find out whats wrong and my dislexia is making it so hard to figure out.

I would like to connect to Suddenlink.net via Optimum.net. It does show up on Optimum.net account on web page. I have a screen shot of the constant results of my days of efforts. I have two other connections via gmail.com and it works fine. I have people who are still using Suddenlink emails to me and I would like to see them on Thunderbird. Thanks for the fine software and any help with this. //... Joe

The latest rev is VERY slow (several seconds) compared to prior revs to process email changes within INBOX (OPEN, MOVE, DELETE, etc.)

Something new is going on internally to the program while the hour-glass appears for a few seconds more than before (I did not change any settings w/ latest upgrades).

How can I change the subject prefix (Re:, Fwd:, etc.) ? I would prefer "RE:" to "Re:" for my outgoing mails. "mailnews.localizedRe" handles recognition of incoming subject prefixes, but I found no pref for my outgoing mails. Thank you!

Hallo, ich habe Windows 11 neu installiert, nun habe ich das Problem, das angeblich mein Mail Passwort nicht stimmt. Ich habe schon alles ausprobiert, die korrekten Passwörter von T-Online eingebeben, die Passwörter geändert, nichts hilft. Ich habe auch schon Thunderbird neu installiert, doch alles ohne Erfolg. Könntet ihr mir bitte weiterhelfen, das ich dieses wundervolle Programm wieder nutzen kann?

Hier noch mein System: i7 6700 K, WIN 11 HOME, GTX 970Grafikkarte, 500 GB SSD, 16 GB RAM, 1 TB Harddisk,

Danke im Voraus

I wish to transfer my Thunderbird accounts (i.e. I have two different email addresses in one Thunderbird installation) from my 'old' PC to my 'new' laptop.

Historically I have backed up my emails by copying the Thunderbird folder from <user>/AppData/Roaming/Thunderbird and pasting it to my backup disk. This has worked well for more than 6 years. In that time, I've had to recover a couple of times by simply re-installing Thunderbird, establishing it with my main email account (ian_and_maureen@yahoo.co.uk), then replacing the newly established .../Roaming/Thunderbird folder with the archived one, thus recovering all my subfolder data in the Inbox of ian_and_maureen... plus a second email address.

I've tried to do this with the laptop, but I don't fully recover the historical data, all I get is the current Inboxes for the two accounts with no historical data. Can you advise me what I'm doing wrong? If this is the wrong way, what is the correct way? It seems essentially the same action as is described by the guide found at Moving Thunderbird Data to a New Computer | Thunderbird Help (mozilla.org)

My PC is running Windows 10 Version 22H2 (OS Build 19045.4717) with Thunderbird Version 115.13.0 (32-bit). The Laptop is Windows 11 Version 23H2 (OS Build 22631.3958 with Thunderbird Version 115.13.0 (64-bit)
