Old computer: Windows 10 Pro, 64 bit Thunderbird 115.10.0 32-bit (Don't know why it's 32-bit version on a 64-bit computer or whether that's relevant)

The Profiles folder is here (with 5 profiles): C:\Users\<User>\AppData\Roaming\Thunderbird\Profiles

The new computer is Windows 11 Pro, 64-bit I just installed Thunderbird (V115.10.0 (64-bit) on the new computer.

On the new computer, the Profiles folder is here: C:\Users\<User>\AppData\Roaming\Thunderbird\Profiles

I followed the directions here https://support.mozilla.org/en-US/kb/moving-thunderbird-data-to-a-new-computer

I basically took the Profiles folder that came with the Thunderbird installation, renamed it (Profiles.orig) and copied in the Profiles folder from the old computer in its place. When I start up Thunderbird, I get this error message:

           Your Thunderbird profile cannon be loaded.  It may be missing or inaccessible

What am I doing wrong? I've updated Thunderbird on the old computer and copied the Profiles folder over to the new computer again. Same result.

Could it be 1. an issue with the user name on the old computer is different than the one I'm using on the new computer? 2. All files on the new computer are set up as local (the user on the old computer started out as a Microsoft user but I made it local so as not to have to use OneDrive).

I'm stumped. Any help will be very much appreciated. If you need any more details I'm happy to provide them.

For months I was experiencing the problem of "Thunderbird not responding" occasionally. It was a short duration issue (a few seconds to a minute). I reinstalled Thunderbird several times without success. I read almost every comment available online about this problem and I tried many ideas and recommendations I found without success. Most recently the problem became so serious that it was not a nuisance any longer. It was nearly impossble to work waiting for minutes to open an email or to continue typing while preparing a message and being interrupted by the problem I am describing. I ran Thunderbird in safe mode and determined that none of the add-ons is causing the problem. I turned the firewall OFF and determined that firewall was not causing the problem. I then decided to run Thunderbird in Offline mode and found that the program works normally. Then while in Offline mode I decided to download more messages and the program asked me if I wanted to switch to the Online mode. I said yes. New emails were downloaded and without going back to the Offline mode I was able to work normally without any occurrence of the "Thunderbird not responding" problem. I have been using this workaround for several days now. I download a number of eamails. I try working in Online mode and I cannot do it. I switch to Offline and work fine. I switch back to Online mode and I don't see the problem any longer for the whole day. Do you have any idea as to the origin of my proble? I am running Thunderbird 115.10.2 64 bit on Windows 11. I had the problem originally using Lenovo T490s and more recenlt Lenovo X1 Yoga

I clicked the 'a' key on a folder in my email and a stack of emails disappeared. Some unread and some requiring a response! They're not in the archive folder.

Thanks!

Hyperlink insertion only works in troubleshoot modes but not in main mode even if all extensions and hardware acceleration are turned off (used this guide: https://support.mozilla.org/en-US/kb/troubleshoot-mode-thunderbird#w_the-problem-no-longer-happens-in-troubleshoot-mode)

Please help me.

Thank you!

Hello. In our company, every employee has an IMAP account, but over time the IMAP profile takes up too much space on the hard drive (100-200GB per user...). What can we do to have more storage space? Can we delete the file? Or will all emails also be deleted from the server?

I upgraded to Thunderbird 115.10.0 (x64) earlier today and now the program is no longer closing completely (I've tried using the X at the top right of the window, and I've also tried File menu -> Exit). I first discovered this when I was using CCleaner to clean my temporary items and it asked me if I wanted to close Thunderbird after I had already closed it. I then checked my running processes and there are three Thunderbird processes that remain after the program has supposedy closed (Task Manager screenshot attached).

Any help with this seemingly new bug is greatly appreciated!

Much thanks, -Snipe

I've been trying out Thunderbird and Spark for the past few weeks, and decided to go with Thunderbird to replace Windows Mail. After uninstalling Spark, I changed all my email passwords, and now Thunderbird can't connect. I deleted my Google and Xfinity email accounts from Thunderbird, then closed and reopened the program, but I'm still getting this error from Google when I fill in the credential info it automatically asks for when re-adding it to my account:

"400. That’s an error.

The server cannot process the request because it is malformed. It should not be retried. That’s all we know."

On the "set up your existing email address" page in Thunderbird, I'm getting this error (see image), even though the copy/pasted password works fine when logging directly into Google.

I also can't reconnect to Xfinity at all. The 3rd party box is checked in their system, but when Thunderbird tries to connect, it looks like it's auto-filling and submitting a password on my behalf, without stopping on that screen so I can change it.

I did this: https://support.mozilla.org/en-US/kb/password-manager-remember-delete-change-tb

And tried all of the suggestions on this post: https://support.mozilla.org/en-US/questions/1434503

What am I missing?

Hi, Excuse my poor English (I am French). Linux Mint 21.3 Cinnamon (64), Thunderbird 115.9.0 (64) no added module - Installation from the Mint list of software. My problem : regardless of the provider (Proton, Gmail, Outlook, GMX - in IMAP), the message menu bar (see <https://support.mozilla.org/fr/kb/personnaliser-la-liste-des -messages#thunderbird:linux:tb115>) does not appear. How to make it reappear ? I think I have tried all the configuration menus and possible right clicks within Thunderbird ; I haven't found anything on the Net ; starting in safe mode did not change anything. I come from Windows 10 where I didn't have this problem. Thanks in advance for your help

When I print an email, TB prints all of this technical jargon such as X-MS-Exchange lines, and what seems to be the background handshake protocols behind the email. I just want the contents of the email printed. May I ask how I fix this, please?

I updated Thunderbird to the latest version and now I have a problem that continues to remain after closing the process.

Thunderbird 115.10.0 64bit (Build ID 20240412173147) OS Windows_NT 10.0 22631

Good Day,

For the last few weeks, when using Thunderbird on Windows and writing a draft email, when clicking on the button to create a link, the draft email window freezes. This also happens if I use the menu bar Insert -> Links...

All other Thunderbird windows remain functioning, and I can effectively continue working, but the frozen draft window will remain on screen until closed through Task Manager.

This only happens when creating a Link, not inserting other objects, like an Image. This problem also does not happen with Thunderbird on Ubuntu.

I am running version 115.10.1.

Thanks in advance for any tips that could be of help.

I want to change the line spacing in my emails to single line including paragraph spacing. Advice given in previous posts says to select Menu then Options. I have clicked on the 3 bar Menu icon and Options is not there. I clicked on Tools in the Menu Bar and Options is not there either. I apparently have to get to Composition, but cannot find a way of getting there.

I have a new PC. After installing Thunderbird onto my new PC, emails from my old PC are not there. Can these be recovered? I have a copy of my old PC hard drive files but not the actual PC. Thanks Jim Ferrier

Sending of the message failed. An error occurred while sending mail. The mail server responded: <work@email address>: Sender address rejected: not owned by user personal@email address. Please verify that your email address is correct in your account settings and try again.

This message suddenly coming up after a Thunderbird update, and I cannot send messages from my work email because I don't "own" it. How do I fix this?

TIA.

I know i have asked this already but i did not receive an answer of a solution and id really like someone to help me with this. It is a duplicate question but again no answer and id really like one . i want to remove it please do not tell me toget a new profile and lose everything i have. there has to be another way

I am having issues with Thunderbird not retaining my email server and passwords. Each time I want to send an email, it prompts me for the password and then tells me that the email address and server don't match. I have tried numerous times to correct this, but it doesn't hold the information. It also switches the server info between accounts. I have 3 different email account and sometimes only one works correctly

I have imported a public key in my openpgp key-management/ In my settings of the end -to-end keys: preference of key technology: choose auto the key technology by the available keys. I have read openpgp standard supports inline en s/mime encryption but what is used by thunderbird when I choose openpgp as key encryption when i type/send an email (w/o attachment by myself). I ask it because my correspondent only decrypts inline encryption.

There is no option for message headers under View. How can I see email message headers in Thunderbird?

I Googled how to do this but they all say there is an option in the main menu under View. Maybe at some point there was, but not now. So how can I see the email headers?
