Thunderbird Support Forum

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.

If I Forward and email with a list of cc: addresses, will the Forwarded emails be sent to the cc: addresses also or do I need to enter a new list of cc: addresses?

I've recently switched from Apple Mail to Thunderbird, and I'm realizing that one of the convenient little features that Apple Mail had that is missing in Thunderbird is that it would intelligently select which email account you are sending an email from depending on the currently viewed mailbox or who you've addressed it to.

For example, let's say I have two email accounts: a personal Gmail address, and a work account with an address that looks something like myname@company.com, with the Gmail account being the default.

If I start writing an email from my Gmail inbox or am addressing it to people whose addresses are totally unrelated from my work account, I'd like it to use the Gmail account, which is what it does.

However, if I'm currently browsing one of the mailboxes for my work account, or I address a new email to one of my coworkers who also has an @company.com email address, I'd like it to automatically set the 'from' address of my new email to my work email.

Thunderbird already picks the correct account when I'm replying. I'm hoping that it can also do so when starting a new email.

Is there any way to do this?

Hello, I've found this article [[Knowledge Base Article|https://support.mozilla.org/en-US/kb/maildir-thunderbird]] which substantially says that the use of maildir is deprecated. Has anything changed from the time that article was posted? I'd like to use maildir, it seems to me a more rational way to store e-mails (and it's also better to make incremental backups).

Thanks in advance Denis

Hello My Thunderbird failed pop access to my Gmail account, at beginning of month. Any try to fix, and even change from pop to imap don't work. I get the windows as shown i images as result. I don't like see oauth/legacy/consent in the URL. - Change setting in Google from pop to imap - Cookie setting updated as forum suggest - JavaScript true as forum suggest

Any hint on forwarding step? Thanks Lars Granath

I've been using TB on 2 of my smaller email accounts for several months and really like the way it operates. I'm nearly ready to add my main email account (web-based Outlook) to TB but have one final question. If I add the account to TB, give it a fair try, and just don't like the results, can I simply delete that account from TB and go back to accessing it via its website? I have confirmed that POP is disabled for my Outlook account so I understand all email remains on the server until I remove it. I also understand TB would leave the email from the account on the same server, again pending some action I might take to remove it. So it would seem that I could delete the account from TB and revert to web-based access for the account, just as I'm doing now, and the folders and saved emails would still be there. Am I overlooking anything?

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'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?

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.

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 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.

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

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?

In the column "Date" field, and in the Inbox folder only, only a time is displayed, but no date. Widening the column has no effect. Date and time are displayed in other folders.

Hi. When replying to an e-mail, Thunderbird has started to place to input cursor in the TO field instead of the message text field (in this case it should be before the answered text).

Any ideas? BR Johnny

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?

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
