When I highlighted the password, it gave me only choices to edit or copy password and the only way I know how to delete a password is to click, "Remove All" and now the "Show Password" button is grayed out.

When I tried to delete my old password in "Show Passwords" by highlighting my old password and hitting the backspace key to delete it and every time I click on the background or hit "Enter", it just pops back on where it was so I couldn't correct it without having to click "Remove all" which turned off the "Show Passwords" in "Saved Passwords".

I have been unable to send emails for several weeks and keep getting the following error message: sending of message failed The message could not be sent because connecting to the outgoing server (SMTP)smtp.1und1.de failed. The server may be unavailable or is refusing SMTP connections. Please verify that your outgoing server (SMTP) settings are correct and try again.

My settings have not been changed so I am wondering what has changed and how i can correct it. My computer knowledge and ability is very limited so please bear theis in mind when offering advice and solutions. Thank you.

When I got into the "Show Passwords" in "Saved Passwords in "Privacy & Security", I had to click "Remove All" in "Show Passwords" to delete it, and now it turns off the "Show Passwords" in the "Saved Passwords" section, and now the OAuth2 is missing.

I want to use thunderbird on a Windows 11 laptop. Tell me how to connect Thunderbird to send and receive emails from email account, jds@sefcik.net, hosted at smartmail.buz.net.

Hi,

My mail account was recently migrated to office365, and I saw that Thunderbird v145 and later supports this natively without the use of a plugin.

However when I follow the instructions to set this up I don't see the Account hub in the same way that's shown in the article.

https://blog.thunderbird.net/2025/11/thunderbird-adds-native-microsoft-exchange-email-support/

instead I see the one attached.

I've tried this on both Linux (ubuntu 24.04) and Window 11 both with my original profile and a completely blank installation. On Linux I've used both the Canonical supplied Snap (from the monthly/stable channel) and the download directly from thunderbird.net.

Any help appreciated.

Hello,

I have been using Thunderbird only occasionally for backing up Google emails after which I delete the emails from Google. I am thinking of using Thunderbird permanently but there are things I'm not sure about.

1). Does Thunderbird automatically integrate Google Take Out mbox files automatically into one email list? When I start Thunderbird, I see files that I have uploaded to Thunderbird (on two occasions in the past and these were mbox files from Google Take Out) but these files are empty. (screenshot attached). When I select the "all mail" folder all of the mails saved since 2005 appear to be there.

2). Does Thunderbird save attachments or only the emails themselves?

I would be grateful for some help so that I can optimise my working with Thunderbird.

Best wishes

Many of my emails received are auto marked/shown as having been read. This means I never know which of my many emails received are new and which I have already read. Particularly annoying as I have a number of aliases and a number of folders to put them in. I am actively considering going back to MS Outlook, which would be regressive.

Attempting to install Thunderbird on an additional desktop using same address as my original computer has. But when I attempt to install on computer #2, Thunderbird doesn't recognize my email or password from computer #1.

well installed Thunderbird on UBUNTU 24.04 LTS doesn't start beyond choice of new profile and selection of old data file from a former UBUNTU installation (UBUNTU 25.10 ) I retrofitted to current UBUNTU 24.04 LTS , thus more stable

Hi, I use thunderbird as both POP and IMAP through gmail. I keep all my emails on my POP thunderbird desktop client. I use IMAP on my thunderbird laptop client, iPhone, iPad via Apple mail when remote, then download the emails to my desktop.

What I want to do is read emails and set them to archive on my IMA laptop, iPhone, iPad. I know Gmail tags the archived emails. How do I stop thunderbird from downloading the archived emails to my POP thunderbird desktop client?

Thanks! Art

I have been using T-bird for years successfully until lately. We have multiple email addresses in Comcast and Gmail, but lately our passwords that we have been using and know are correct because they are written on paper and Keypass, are being changed somehow so that they will no longer work. When we look at the saved passwords in Thunderbird we see some have been changed on a certain date that we did not do, and the password listed now must be about 200 characters long. Then when we go to change the password, it may be listed as changed. Then when we try to send a message with that email address, we get an error message saying, for example, smtp.googlemail.com and a wrong username/address completely. I can find no way to correct the username email in any settings in Thunderbird. I have searched the Thunderbird HELP files many times, but am unable to find any of this addressed anywhere. After trying to fix these problems for most of 3 days now, I have get rid of Thunderbird for an email client that works correctly!!!
