Thunderbird Support Forum

When I'm on a website with an Email Link (Example: Support) and I click on the Email Link nothing is happening. Before the Supernova "upgrade" any Email Link would automatically open to my Thunderbird Email Account Email. Now, nothing.

I found a Mozilla Support Post for Windows 11: Apps>Default Apps>Thunderbird>MAILTO, but it is already set to Thunderbird.

Does anyone have a Fix?

Thank you in advance.

I am trying to add a MS365 mail account to Thunderbird 115.4.2 and keep getting a mail fail message, telling me the login failed, I am receiving mail into this mailbox without issue but sending doesn't work. I get an error message with 3 options, retry, enter a new password or cancel. Enter new password doesn't work.

I have set up , as far as I can tell, correctly, the password on the account works for incoming mail. The default smtp server for this mailbox is correct: smtp.office.365.com, port 587, STARTTLS, Oauth2 and my correct mail address for this account. Any thoughts as to what I am not doing?

TIA

How can I set Thunderbird 115.4.2 (64-bit) to have html composition after a normal click on "+New"?

My copy of Thunderbird 115.4.2 (64-bit) DOES NOT offer in settings-> Composition a "Compose in HTML" choice. (It does have an HTML Style setting.)

I can only compose in HTML by ditzing around with special "hold shift" when clicking on the +New button.

I searched and I know others have had this issue as well but so far, none of the solutions that I've found have fixed it. This just started happening yesterday randomly in the middle of my work day, NOTHING had changed! One minute, I could receive emails and then next, this error started to appear: Unable to write the email to the mailbox. Make sure the file system allows you write privileges, and you have enough disk space to copy the mailbox.

I can still GET EMAILS ON MY IPHONE and can STILL SEND EMAIL via Thunderbid - I just cannot RECEIVE EMAILS IN THUNBDERBIRD ANYMORE!

Any solutions? It's really a pain to have clients emailing me and have to check and respond to those on my phone.

Thank you!

Recent changes to #Thunderbird software are causing replies to my emails being attached to previous emails of the same thread and are not visible when they come to my inbox. Why and what solution? thanks Charlie

In my Thunderbird email messages sometimes appear not readable emails. Something similar to html tekst.

Please help me to solve the problem. I cant find the solution.

I did not find this exact question after looking through multiple pages. I have two email accounts, that is easy enough I followed the directions online, and almost had this set up.. But then I realized I did not know how this would work. I want/need the two to be kept separate. In other words I don't need the first email displayed be from my personal account, and the second from my junk account, the third fourth and fifth from personal, etc....Ok, just hit me, I need them under separate tabs, that's what I've been trying to think of.

Is that how it will automatically be set up, or can I even get it to do that? If so how?

Thank for the help.

Using Mozilla 115.4.2 (64-bit) on MacOS 14.0

I have plenty of folders and subfolders on my Office365 account (institutional) that I access using Thundebird.

When I reorganise my emails, moving messages from the Inbox to other folders, create new folders, rename folders etc. Thunderbird loses the subscription settings. At its first launch after such reorganization, I see only few folders, so I need to subscribe again to all my subfolders.

Questions: subscribing to almost all of the subfolders is painful.

Would you be so kind to add an option "subscribe all folders", so a user can only select those folders that need to be unsubscribed?

I somehow activated the number of emails and their volume used and can't find a way to undo this. This ad annoys me. I have win 11/64-bit and Thunderbird 115.4.2 (64-bit) running

Ich habe irgendwie die Anzahl der Mails und dessen verbrauchtes Volumen aktiviert und finde keinen weg dieses wieder rückgängig zu machen. Mich nervt diese anzeige. Ich habe hier win 11/64-Bit und Thunderbird 115.4.2 (64-Bit) laufen.

WHEN RECEIVING A NEW EMAIL, I GET A MESSAGE: "ONLY THE HEADERS FOR THIS MESSAGE WERE DOWNLOADED FROM THE MAIL SERVER", THEN I HAVE TO DOWNLOAD THE REST OF THE MESSAGE. HOW CAN I CORRECT THIS?

I am trying to set up MailerLite for my website email list. Whenever I send the verification email from MailerLite, it doesn't reach my inbox for my custom domain email (hosted on Thunderbird). I've sent emails from MailerLite to other emails, no problem. I've sent emails to my inbox, no problem. Do you have any suggestions for why MailerLite isn't communicating with my custom domain email? Thanks!

Thunderbird instalado en Windows 10 se cae permanantemente, despues d euna rato de funcionar windows informa que no responde y no hay como recuperarlo, solo cerrarlo y volverlo a abrir.

Does "remove account" under "Account Actions" remove just that account or all of them? In other words, I have 4 accounts (email addresses). Will I have 3 afterwards?

My Thunderbird standard display has the message displayed below the list of incoming messages. This message pane take up "Several" lines of display and also duplicates the information in the above message window. Its a waste of space and the actual message has to be reduced in viewable size cause the header block uses it all up.

The area circled in red I want total control over.

Show me how.
