Thunderbird Community Forum

Hi there,

I currently have three email accounts set up in my Thunderbird client. I’d like to disable the automatic marking of messages as read—but only for one specific account (mainly for my colleagues’ convenience, as it’s a shared inbox).

In Settings > General, I see the option to turn off "Automatically mark messages as read", but this would apply to all my accounts, which isn’t what I want. I’ve checked the Account Settings for the relevant account and couldn’t find a per-account option. I also looked for an add-on that might help, but so far, no luck.

Has anyone found a workaround or solution for this? Any advice would be greatly appreciated !

Thanks in advance, Cheers.

I get the following error whenever I start Thunderbird :-

I can no longer download my email from the server to my Thunderbird email client since I removed the specifics for the server with the password. I need to add it back but I don't know how. Is there a file I can edit?

I wish to add email identity deborahstpeter1@gmail.com to my account keweston82@gmail.com. Deborah is in a nursing home and as Power of Attorney I handle all her financial affairs on line. I had to replace my old computer which included Deborah's email in my Thunderbird email account but I've been unsuccessful getting her added to my new computer. I'm 83 years old and operating my old computer, which is where Mozilla's responses are going, and my new computer from which I'm communicating with Mozilla, plus two different mouses, I'm making a lot of mistakes i.e. click a computer scream with the wrong mouse. I wish to add Deb to my account with as little involvement on my part as possible. You can send a verification code to deborstpeter1@gmail.com and I will be sure to use the correct mouse.

I have TB 145.0 on a Mac.

When my trash gets pretty full, I empty the trash then restart TB just to have a fresh start. Been doing this for years. Well, I did it just now and when TB restarted I got a warning that said Thunderbird is an app I downloaded from the internet, do I trust it? First time that has happened.d I clicked on the button that said to go ahead and open it.

When TB opened, it wasn't aware of any of my email accounts. It's almost like I was opening it for the first time – except for 187 random old emails in an inbox.

Is there a way to recover from this? I had a lot of emails stored in inboxes and outboxes that would be disastrous for me to lose. They aren't there right now.

I am trying to add an Proton mail account to Thunderbird using the Proton Mail Bridge (PMB). In the PMB guide it is recommended to uncheck Account Hub in the Setting>General. The problem is that the Account Hub still pops up when trying to add a new mail account - it simply refuses to go away regardless of several restarts of both the computer and the mail client!

My ISP has made a change for "third-party" accesses to its e-mail (which still works fine on its own website e-mail access page). I need to check my Username, Password, SSL, Protocol, Incoming & Outgoing Server Ports. BUT I don't see on my Thunderbird page where to find these: it's my preferred way to do e-mail! Where are they??

I have a Google Workspace account which has my company name as a suffix, ie. @chase-design.net NOT @gmail. com. When I try to add an account automatically using the company suffix, Thunderbird does not recognize it. Is there a set-up guide that shows me step by step how to manually configure that type of setup?

Thunderbird forces me to use the new amount hub. And I get authentication error when trying to setup outlook.com email

I just download the latest version of Thunderbird, and try to add my pop mail account. But after i enter the info of outgoing server settings, the Continue button is gray and can't be clicked. once I try the test, it says that Thunderbird failed to find the settings for your email account. Can't find a server. Also i find that there is no place enter the password of my mail account.

Comcast has sent our accounts to yahoo. Email name remains the same. I wish to continue with Thunderbird. I haven't been able to and don't want to lose all my Thunderbird settings and files. They have been transferred to yahoo mail.

I've had a POP3 account for years, with no problem. On a second computer I had a second TB installation that used to get its emails from a folder on the main computer. This suited our purposes very well. The second user could access all my e-mails, and her sent messages also appeared on my computer.

Alas I updated TB, and have lost this capability. Ideally I'd go back to it, but the only way forward seems to be to set up an IMAP account. I have tried this, following the instructions on the Mozilla web site. It's all very easy, but I end up with a message: "Thunderbird failed to find the settings for your email server".

I have of course checked that the settings are correct, but I can't get past this point. I have tried disabling my Internet Security (Bitdefender) but to no avail.

What should I do next, please? I'd go back to an earlier version of TB if that would enable my older method of working.

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!!!

I have created a new gmail address for my wife. Would like to add this address to my existing Thunderbird Mail account so that her emails also come to my Thunderbird email account. Not sure how to add her address to do this.. Thanks
