I want to use Thunderbird as a one-off back up of my source email folders.

On Thunderbird PC, I have done this under Fetching mail settings with "Folder Poll Frequency" set to Never.

On Thunderbird Desktop Account settings are different. On Server settings, I have unchecked for new messages, but they are still coming through. Any advice how to stop the messages synchronising from the source email system?

I will then delete a lot of old messages on the source system, knowing they are available on Thunderbird desktop

Why am I getting this message when I try and send an email from my Mozilla email client: Sending of the message failed. The message could not be sent because the connection to Outgoing server (SMTP) smtp.gmail.com timed out. Try again.

As so many have experienced, but I have yet to find the actual solution, I will bring up the issue.

I recently purchased a new computer. Installed Thunderbird, created all the mail accounts I have and... no problems. All the accounts, once created, populated with emails. For 3-4 days, there were no issues.

Important to note: I let TB use all the default settings. And once everything was up and running >>>>I did not change anything<<<<<.

Then a few days later, I started getting the following messages for two accounts that had migrated from q.com to myctl.net. Entering the 100% proven-correct password results in the know endless-loop of entering the password and the same pop-up error message. The PW is 100% correct as I can go to Centurylinks' website and login using that same, exact password and read my emails.

I've spent enough time trying all the suggestions here, reddit, facebook etc so I'd thought I'd see if anyone has actually found a solution.

Hi have various hotmail and live accounts already active in Thunderbird. Tonight, I tried to add a new hotmail account for my mom. The hotmail account is active and working well using the microsoft web browser.

I tried to add the new email to Thunderbird and in the first stage a green box with a checkmark appears " saying Configuration found in mozilla database.

IMAP box says: Incoming Imap SSL/TLS outlook.office365.com

Outgoing SMTP STARTTLS smtp-mail.outlook.com

username xxxxx.hotmail.com

I press done, and a yellow box appears saying "Unable to log in at server. Probably wrong configuration, username or password. Now I did notice on my other hotmail accounts in Thunderbird, the outgoing says: smtp.office365.com and NOT smtp-mail.outlook.com I tried making the new account exactly like my other 5 live/hotmail accounts. Outgoing> smtp.office365.com. And still no go. The new email addy won't connect.

So I thought, maybe it's a bad email or the way I created it. So I created a NEW hotmail email address and same thing. Followed all the steps and same yellow non connect error box appears. The setup in the picture is exactly like my other accounts - and they all work fine. Has anyone tried to add a hotmail addy recently? I never had these issues when I set up the other addresses 4 or 5 years ago. Thanks guys

Thunderbird 147.0.1 (aarch64, macos, m2)

Team, After spending many many hours creating 14 search-folders that can find all of the right emails in approx. 20 "real" (local) folders.

Then I renamed 10 local folders and noticed my searchfolders disappearing!?

Big panic. Now, only the last 2 created searchfolders where there. The rest was gone. Realizing that the searchfolder config is in a file called "VirtualFolders.dat" I instantly took a copy. Restart Thunderbird: Now only 1 searchfolder was left. The copied virtualfolders.dat file still had 2 searchfolders in it but the rest is gone. There is no other copy/backup of this file.

These search folders are the only thing that generated some sense in gigantic piles of email.

Does renaming local folders KILL Virtual/Search folders?

thunderbird Is working fine, but this message crops up every few minutes, and requires 4 - 8 Cancel clicks. I've tried "Open anyway", I've deleted and reinstalled the app several times, and tried the terminal command "xattr - cr" and dragging the app into the window. Is there a proper fix for this. V. grateful for any solution. TIA Brian

For some time now, TB (147.0.1 (64-bit)) has been VERY slow loading, the first thing in the morning. If I close it and re-open, it opens at the normal--and desirable!--speed. Any thoughts? Regards, Dave

I had just started utilising Folders. Today I wanted to move an important email where I could easily find it again. I created a new folder, went to the inbox, clicked on the email in question and moved it to the new folder.

Then I went to the new folder to check that it was there safely and it was and I shut down my laptop.

Later I got home to start work. I looked for the file and the folder was empty. I ran the search that I had run previously and it now returned nothing found. The email had vanished.

I moved some rubbish emails to the same folder, none of them arrived there, all have disappeared and are not to be found in the deleted folders either.

Really annoying and frankly a deal breaker for using this software going forward without a satisfactory solution.

Running Linux Mint on a Lenovo ThinkpadT490 Many thanks

Hey, I want to set up my .gmx.de mail account in thunderbird (140.10.0esr (64-bit), Mozilla Thunderbird Snap for Ubuntu). it used to work, on my phone and the gmx website it is working. I did not change any of my credentials but suddenly it raised the "unable to log in to ..." error on my laptop only (Ubuntu 24.04.4 LTS). After several tries I deleted the account and tried to set it up again from scratch. It finds a server profile which is consistent with the one on my phone (where it is working just fine) but login is not possible using the same password.

Hi community,

I want to have the same font and font-size in:

• my HTML message body text
• my signature.html file

so I can send consistent and nice-looking e-mails, like you would expect.

Here are my current settings:

• Settings > General > Language & Fonts > Fonts >
  • Default font: Arial
  • Size: 12
  • Advanced: For both "Latin" and "Other Writing Systems" I have the settings you can see in the attached screenshots.

I heard that these settings are for personal viewing.

• Settings > Composition > HTML Style >
  • Font: Arial
  • Size: Medium

I heard that these settings are for viewing by recipients.

The first line of my signature.html file looks like this: div style="font-family: 'Arial'; color: #222; line-height: 1.0; font-size: 14px;"

There is always a slight font size mismatch of the message text with my signature.

I unsuccesfully tried tweaking the html font size values in px or pt to match the given size in Settings > Composition > HTML Style for Medium or Large.

It seems that the available font size granularity of Medium or Large just does not match corresponding pixel or point values?

I would be extremely grateful if someone can guide me on how to achieve this!

If there is no valid solution for this problem, I'm happy to open/report an issue on this.

Thank you and have a wonderful day

I recently moved thunderbird from my Win 7 laptop to a new laptop with Win11. All was OK for awhile. One day all of my Local Folders were no longer in alphabetical order. Some folders, like Outbox are under Local Folders. Is there a fix? Please don’t tell me to uninstall and re-install.

I am having issues getting thunderbird to connect to my 2 hotmail accounts over the last week or two. According to isitdownrightnow.com, outlook has been down for about 200 days and is this really the case? My wife is not having any issues with her hotmail accounts, but I am. I have tried several different settings and attempts and did seem to have it setup, only for it to fail again and again.

This is getting ridiculous. I am using Windows 10 Pro and I am using Thunderbird 150.0.1 (64-bit). I am using Avast Antivirus and Comodo Firewall, but my gmail and yahoo mails are just fine. If anyone here has any information that I am missing or maybe I am making some kind of mistake in my setup, I would really appreciate any and all help or suggestions. Please ask for details about my setup and I will be happy to provide it. Thanks, Shawn

I would like to know if possible and or how to set up a standard "footer" if you will, to end my emails with. I am humbled to have several initials after my name, and would like to be able to have a standard button or actino to perform, to shortcut those answered emails with that sign off... Is is possible? Thank you

When adding a new email account, the built-in web browser launches and displays the OAuth screen. To verify the security of the destination site, I want to click the green lock icon in the URL bar to check the details, but I can’t click it.

Does a green lock icon mean a secure connection has been established?

When attempting to send a web address under "file" tab using Thunderbird, there is an offering "email Link". "email link" does nothing with Windows 11 but worked with Windows 10? I have to copy and paste to send a web address to a mail recipient.
