I-Thunderbird Community Forum

Hello community!

I use Thunderbird desktop for two emails: personal outlook.com (ms365 or whatever ma calls it) and school exchange account.

Exchange works fine using owl and is able to sync calendar correctly. For personal email, it appears I can only connect via imap instead of MS’s protocol, which limits its ability to sync calendar. I’m wondering if there’s a way to login personal ms email similar to exchange to sync calendar etc.?

Thx in advance for ur help :-)

Have used the SeaMonkey suite for my email since Netscape. It seems the latest version SeaMonkey will not work with Apple’s latest OS on my MacBook Air, and is unlikely to be modified to work. So, my plan was to use Thunderbird, but when I Google to see if it (Thunderbird) is compatible I get an AI generated message that the Thunderbird team is working on a new Apple compliant version. Searching this forum I can find no reference to any Apple compatible version. Anyone with updates on Thunderbird versions that will work on my MacBook Air and the macOS Tahoe Currently happy enough with macOS Sonoma and SeaMonkey, but the nags to upgrade are annoying Thank you for your time Cheers Ralph

I generated a CSR file via the instructions at https://support.mozilla.org/en-US/kb/instructions-smime-certificate-using-csr#thunderbird:linux:tb145 . After submitting and receiving a certificate from a CA, importing it the People tab of the Certificate Manager does not do anything: nothing new appears in the Your Certificates tab.

Where are the private keys associated to the generated CSRs stored? How can I access them to resolve this?

Hello, I'm using the most recent version of Thunderbird on a desktop using Windows 11. Just this morning (Aug 11), all incoming email to all my four accounts are coming in with no subject or correspondents showing and when opened the email is not formatted in HTML, just plain text and lots of code. I have tried several fixes with no success: repair folders, turn off all add-ons and anti-virus protection, uninstalled and reinstalled software. Can you help, please? Thanks!

Hi, Having trouble with JUNK mails, from unknown adresses. I've found in "account settings" "Trust junk mail headers set by" might be good for me but no idea which one to choose!

I'm not able to log into yahoo e-mail via Linux Firefox (145.0 (64-Bit)): The error message is "We were unable to log you in. Please try again from another device." I can log in with Chrome (Linux and Windows) and Firefox (Windows). My issue is to switch from POP3 to IMAP in Thunderbird. There the same error message occurs.

Hello, I can receive email messages but unable to send them out. The error message I get follows:

The mail server responded,( bettyweber@shaw.ca sender) rejected AUP#POL. Verify your email address is correct in account settings.

What can I do to fix this in Thunderbird?

I checked with my service provider and I can receive and send messages through webmail but not Thunderbird.

Thanks. Betty

I've used TB successfully for many years to access several Yahoo and Googlemail accounts. Windows 10. Recently the Yahoo accounts don't work so I've tried several times deleting and reloading them. This may be a red herring but the trouble seemd to start when I installed TB on a new Windows 11 laptop and failed to load the Yahoo accounts. I've tried following both Mozilla and Yahoo help articles but ultimately success is partial at best (i.e. incoming works, outgoing fails) This is the sequence I have followed

251128 tried this: Deleted all yahoo accounts in Thunderbird

Edited outgoing yahoo server to

 smtp.mail.yahoo.com
 Port 465
 SSL/TLS
 Authentication method OAuth2
 User name johngherrett@yahoo.com

Added yahoo account johngherrett@yahoo.com name and email address

opens yahoo! login sequence enter email and yahoo account password - FAILS

logged out of Yahoo mail open elsewhere

Accept 'Configuration found in Mozilla ISPDB'

opens yahoo! login sequence enter email and yahoo account password - FAILS

Account Hub window 'Choose your email type' pick 'Edit configuration'

Changed Incoming server settings to: POP3 pop.mail.yahoo.com Port 993 SSL/TLS Auth method OAuth2 username = email address

Test

'Outgoing server settings' 'The following settings were found by probing the given server' SMTP smtp.mail.yahoo.com Port 465 SSL/TLS OAuth2

Continue

followed guidance from Mozilla article: https://support.mozilla.org/en-US/kb/thunderbird-and-yahoo Exit Thunderbird Wait a few moments for background process to complete Start Thunderbird

counted to 10+

restarted Thunderbird Yahoo account is not there Googlemail account is there - OK

'Set up another account' - email started again Name & email

opens yahoo! login sequence enter email and yahoo account password - FAILS: 'Something went wrong' - not helpful 'Go to help' in Yahoo dialog opens another page in kanji(?) close this

Go to https://help.yahoo.com/kb/sln27791.html Login to yahoo account 'Ways to securely access Yahoo Mail'

Use an app password ************

Signed out of a 'current sessions' even if not recognised. (Except 'current device' which is the login just past.

External connections-> Create app password App name : Thunderbird Generate

Copied to clipboard ********************

Returned to TB

entered password 'Continue' Spinning icon and re-opens yahoo login dialog entered normal password 'Something went wrong'

entered app password 'Something went wrong'

Despite this, after closing the yahoo dialog, TB says 'Account created successfully'!!!!

Inbox appears

Note:server settings now set somehow to IMAP / normal password

Testing outgoing: Message fails, Yahoo dialog login fails Edit outgoing server which remains OAuth2 Changed to normal password

Tried app password - failed Tried normal Yahoo password - failed

Have two email accounts: Outlook and Gmail. They check and pull mail off the servers independently. I would prefer to only have to look in ONE account for my mail. I have chosen Outlook. I am having problems getting Thunderbird to push the emails in my Gmail folders to the corresponding Outlook folders. Is that because it can't be done? In settings for GMail account, under Copies and folders, I push: Sent messages > Sent on d*******1@outlook.com Archives folder > Archive on d*******1@outlook.com Drafts > Drafts folder on d*******1@outlook.com but they don't seem to be going there.

Is there a way to move messages in GMail TRASH to Outlook DELETED? As you can see, I'm not very aquainted with these things and am pretty confused. Any help appreciated.

I have two accounts with Thunderbird (*@talktalk.net and *@tiscali.co.uk). Each account will receive incoming emails (with or without attachments - single addressee or part of a group email). Periodically outgoing emails are blocked, with the error message 'Sending of the message failed. An error occurred while sending mail. The mail server responded: Reject for policy reason. Please check the message and try again.' Usually the issue seems to fix itself - this tome it has lasted longer than usual. Please can someone suggest a remedy? Tony

I have built up a collection of more than 400 deleted emails in my 'Deleted' folder. I am sure I will not need to refer to any of them again, and I would like to finally remove them. In the past, there was a command among the various sets of commands at the top of the page, which removed all of them, after confirming that this is what I wished to do. I can no longer find this command. Please tell me where to find it. If it no longer exists, tell me how to deal with 'deleted' material.

Attempting to add a gmail oauth account in TB fails authentication using verified account password. (The account requires two-factor authentication using an authenticator app, but haven't tried that as a password) I have removed the account from TB, and the saved passwords for the account. I then added the account back to TB but get the same "Failed authentication" notification without any opportunity to register a new password. I can not find a cookie to remove and retry the process.

How do I stop all the messages subthreads from being populated on the message tab? For example, with I open a message with subthreads, all the trailing messages are displayed on the tab. The only way to get them off the tab is by clicking the x in every message. A real pain. I don't want this. How do I stop it?

I migrated one mac, which was intel based, to another, which is M4. It all went fine. I have the same versions of OS and Thunderbird on each, before the migration. The new machine is a 2025 Mac Studio. The old machine is a 2018 Mac Mini, 6 core Intel Core.15

On the old machine in Thunderbird, under my user, all my files are listed. On the new machine, files are not listed.

I saw a lot of information/suggestions to replace the Profile folder under: USER/Library/Thunderbird/Profiles And I copied it straight over from the old machine, with negative results.

I did notice that under profiles, it continues: m8mojurw.default-esr/Mail/Local Folders/ where there are some other goodies, some of which are "documents".

however, on the new machine, those same files are there, except they are "unix executable files"

I have migrated many times over the years and this hasn't happened.

I have done all of the suggestions I found so far, such as the Profile copy/past, reinstalled Thunderbird from scratch, looked thru comparisons of the Account Settings....

Oh, a couple more things:

If I look under my user and go to "Account settings" then "copies & folders" to looks different on the 2 machines. The old machine has: a check next to "Place a copy in" and under that a dot for "Sent folder on:" and my user name. On the new machine there is: "Place a copy in" and I cannot write into the "sent folder on" space, I can only select Choose and Account -> Local files as if the user doesn't exist (?) Thanks

MY SYSTEM: Thunderbird 140.5.0esr running in Linux Debian Bookworm

I have created a filter from a recently received message via pop. The settings are: OK Manually Run OK Getting New Mail: Filter before Junk Classification

Match all of the following From Contains xyz.co.uk

Perform these actions: Move message to XYZ on my mailbox

Press OK

In the Message Filters window, Run selected filter(s) on: XYZ Press Run Now

There is no response, and all the messages remain in the Inbox.

I have repeated the Run Now process on an old filter (by moving the message back to the inbox), and that works fine.

The only oddity of the current message is that it is a no-reply message eg From = no-reply@xyz.co.uk

Any ideas welcome!
