Thunderbird Community Forum

Hello, I just installed a clean version of Thunderbird (version 146.0.1) and set up my email accounts and CardDAV address books.

I do have multiple address books and I tried to find a setting to show the name of the address book for each contact shown in the suggestion list for recipients when composing a new email. However, I could only find a general setting to get suggestions for recipients from local address books, nothing more specific.

On a different device I still have Thunderbird 140.6.0esr installed. There, the suggestion list does indeed show the name of the address book next to the suggested contact: "name of contact <email@address> - name of addressbook"

I tried to find a corresponding setting for this in version 140.6.0esr, but without success.

So I'm wondering:

1. Did the style/layout of the suggestion list change in recent versions?
2. Does a setting exist to show the name of the address book in the suggestion list?

Additional info: The only extension that is installed and enabled on both devices is ImportExportTools NG.

My old laptop crashed and burned, but I had a profile backup. I used the transfer tool to install the profiles on my new computer, but had a couple problems: 1- the calendar didn't transfer over. I fixed this by copy/paste Calendar-Data and calendar-data.sbd from the default-release folder . 2- No sent records were copied over. I tried copying over a sent.file (375 mb) and sent.msf from a different default-release folder (there were two default-release folders in the older profile backup, I'm not sure why). This did not update the new installation with the sent records. So my question is, how to I update the sent folder in the new build from a older backup, so that all the records are included. Win11 up to date with latest Thunderbird and Firefox versions. Thank you.

For several weeks (I have a work-around for accessing emails) I'm unable to open Thunderbird. First instance of this was Sunday evening Dec 28. I've attached a screenshot of what I see.

I have uninstalled and reinstalled Thunderbird (twice) with obviously no joy.

Any insights would be appreciated.

Please fully explain any file or procedural references; in other words, please do not assume I lmow what you're talking about.

Thanks in advance.

I'm trying to move my thunderbird data to a new computer. Both have TBIRD 140.6.0esr installed. Old computer is Mac OS 11.7.2, new one is Mac 15.7.3. I've copied and transferred the files same as Mozilla says to: (user>library>thunderbird folder to same on new computer) I keep getting this error message: A copy of Thunderbird is already open. Only one copy of Thunderbird can be open.

This is a fresh new computer, Thunderbird has never been installed. I am stuck. HELP.

I have had my @yahoo.ca email for many years. I have always used Thunderbird to retrieve my email and read it locally on my desktop. Recently when Thunderbird launched Rogers take over and wants me to lo in to rogers. It is not a Rogers.com email address, it is a yahoo.ca email address.

Why has Rogers taken over my email.

I can still access my email on the web at the yahoo.ca website, but I want it back in Thunderbird as well.

Здравствуйте, нужна информация, как можно IMAP логи в клиенте собрать, дополнительно, настроить вывод только нужных полей

https://www.mailenable.com/kb/content/article.asp?ID=ME020591 из данной справки удалось их собрать, но тут не чисто imap, а еще какие-то системные.

After many years of using Thunderbird with an AOL account I changed my password in AOL to increase the security. So I had to install the AOL account again in Thunderbird. I created an app password in AOL and put it in Thunderbird. Everythin fine so far. AOL login window opens automatically. But after login to AOL the message "somthing went wrong" and "try on anther device" pops up. I tried it on several PC's - no way. Other mail clients like Mailspring oder Mailbird did work with the AOL account. What is the problem?

Several times a day, TB pops up a message box with the following...

The folder 'Inbox on email@domain.com could not be compacted because writing to folder failed. Verify that you have enough disk space, and that you have write privileges to the file system, then try again.

I have a few accounts in TB, and it does this for all of them, but at seemingly random times.

Everything seems to work, it's just annoying to have these messages pop up.

I have 0.9Tb free space on the disk, so I don't think it's a lack of space! I also have admin rights to the file system, so that's not it either.

Anyone any idea why I get this? Thanks

I just downloaded Thunderbird because Outlook is doing a bad job or preventing on these junk emails and I'm wasting too much time sifting through all the junk emails every hour. Now I have Thunderbird and I don't see an option to mark an email that is in my junk folder as not junk.

Dear Support Team,

Could you please make the "Busy" and "Out of Office" colors in the form (screenshot attached) more distinct from each other?

Currently, they are very hard to tell apart visually when assessing an employee's availability in the calendar.

Thank you for your consideration.

Just installed version 146 and deleted all my old profiles because there were too many errors with TB syncing renamed folders and not the new versions.

Selected EWS to attach our Office365 account which all seemed to work well, but it only finds a few of my folders (luckily all correct), but doesn't find Inbox, Trash etc.

It also doesn't seem to want to download all the email, despite selecting that in the Account Settings.

The Subscribe option is not available under the File menu.

Been using it for 25 years or so, but may have to give up if I can't get my inbox.

Screenshots attached showing what Thunderbird shows vs. OWA.

Thanks for any ideas.

How do I ensure that archived messages go onto my local computer and are removed from my e-mail account on the cloud? (I use CPANEL with a strict limit on space.)

Whenever I forward an email, I end up with two copies of the forward in my "Sent" folder. I can't be sure, but I think this behavior started recently and has not always been the case.

New email and replies do not create duplicates.

Is there some setting I can adjust to stop this happening? Thanks.

Okay, I am trying to set up Thunderbird for my wife's service club's email (gmail account). It just will NOT recognize the password during the account setup. Everything goes along fine until the available configurations come up and I hit "Done" (same for either configuration + trying to use the "manual" function).

Pop up window opens that says "enter credentials" in the header, but page is blank. Alternately, if I exit setup but stay in program and then use the "new account" option, no pop up, but same as with popup, I get "Checking password" for an extended time and then error message about user name or password. I have verified we have the correct password by logging into gmail directly using it.

I am totally stumped here. The laptop is a Dell Inspiron 15 5000 running Win11 and Tbird version is140.4.0esr (64 bit)

Why do I keep getting these? See image.

Thunderbird will not connect with virginmedia.com outgoing or incomimg email servers. It was working fine several days ago. All of the settings look to be correct but a message appers saying that the Connection to pop3.virginmedia.com server has been reset. I have a recovery code from virginmedia but cannot see any way of entering it in Thunderbird.

I have my OS (F43 Budgie) and Thunderbird in dark mode. When I click reply to an email I get black text on a dark background.

Question number one: what will the recipient see exactly? Question number two: how do I setup Thunderbird so that I can read the reply I'm typing?

Hey all, here's my issue:

I recently switched from macOs to Linux mint and started using Thunderbird again. I have three email accounts.

(1) Business, hosted through godaddy on an outlook/office365 platform (2) private on mail.com (3) private on web.de

Initially, i set up three. Accounts 2 and 3 were fully functional (imap) from the get go. Account one had issues sending emails.

Yesterday I sat down to finally try to solve the issue. In my "turn everything off and on" mindset, i completely reset (or so i though) TB, deleted all three accounts, uninstalled TB, reinstalled TB and set up the accounts again, starting with account 1.

When i finally got it running i realized the issue was a checkmark regarding smtp authentification (also a known problem with office365 running on client software apparently) on the microsoft backend, and not on my computer.

After that was set up, i tried adding my other two accounts. Now, this doesn´t work any more. I get timeouts in the setup process. I tried both, adding through the account hub and without it, it just does not work. All the credentials are obviously correct, so is the imap/server data input. So i think at least.

Thanks for any suggestion in advance.
