After over 10 years of TB its time to move on to a mail client that actually works. I manage 10+ different E-Mail addresses across 3 domains, Since September, the ability of TB to actually work is hit and miss. (Wont get messages, wont send messages, says messages are sent when theyre not, slower than molasses in January, overall TB has really gone down hill IMO) I dont have the time or the patience to go through and try to change a bunch of settings and do all this stuff (across 10+ email accounts, that used to work fine, but no longer work due to the 'upgrade'), just to find out its so screwed up that nothing works and I lose everything again.

So, what I would like to do, is extract client E-Mail address out of TB, so I can put them into a new email client that actually works.

I have tried upgrading down grading before I uninstall it, Id like to get my information out, rebuilding my address book took forever last time.

All E-Mail is stored server side, so not worried about losing anything there.

I have moved to Thunderbird (latest update to version 115.4.1). In my old mailprogram, when using HTML, I could compose texts from different sources, then format the text altogether, regardless where they came from and the text appeared as intended at the recipient. In Thunderbird I never really succeeded with that. When I compose text from different sources in a mail, I find no way to assign the same font size to it, not to speak about font type. When I check by sending mails to myself, the texts appear in different sizes, whatever I do. A solution at the moment is to compose the mail in a Word processor, format it there and then copy & paste it to the Thunderbird mail window. But that can hardly be the only way.... Is there any way to format mail when the content consists of texts from different sources?

Hello, I have Thunderbird running on two different OS's. Linux (115.3.1) and Windows 11.(115.4.1). Both act the same way. Both are have the same email address and are linked to two gmail accounts. I have noticed that web based gmail email there is only a "Sent" Folder. On Thunderbird there is a "Sent" and "Sent Mail" folder. on one account the other only has "Sent" They are not always in sync. When I send an email, sometimes it seems to "Hang" sometimes not. I am wondering if I can remove the "Sent Mail" folder or the "Sent" folder as that could be causing the problem?

Thanks in advance.

i just got version 115.4.1 i no longer can recieve emails from my microsoft 365 account. I have checked the settings that outlook recommends. but i keep getting an error message about wrong password,(which it isn't). i am able to send emails. Please help. drmark@vtcbd.com

I downloaded the new version of Thunderbird Mail, and now, I'm having continual trouble sending messages (but no trouble receiving them). A pop-up window keeps appearing requiring me to re-sign into my Microsoft account, for some reason, but whenever I press "continue" to sign in, nothing happens, and selecting "cancel" also has no effect. I'm already signed in to my Microsoft account on my laptop, anyway, so I don't know why this window keeps appearing, but I assume it's related to the fact that I'm having trouble sending e-mail. I have to keep closing the Thunderbird program and re-opening it every time I want to send new messages. This is becoming very tiresome. I've already tried closing and re-opening the Thunderbird program, but that doesn't fix the problem. I'm working on a Mac, with the latest iOS. All suggestions appreciated!

I've been upgraded to 115, like it or not, and now my list of visible email titles will only shorten to 10 emails instead of the previous 4, which leaves very little room to view an opened email. IOW, the double arrow will only let me raise the bottom boundary to be below a list of 10 emails. How can I shorten it back to 4??

I got Thunderbird to better manage my vast number of emails and frankly delete the big ones, as my webmail provider had stopped including a "sort by size" function (just as attachments seem to be getting bigger and bigger) and someone recommended Thunderbird. However, when I go to "View-Sort by", size is not able to be selected. I see someone asked this question or something similar recently and the solution says "If the Size column is enabled (right-click any column button to enable columns) , the message (including attachments) size is shown as in the 1st attached picture. Sort by size by clicking the Size column button. To show only messages with attachments, click the paper clip icon on the Quick Filter Bar."" But I have no idea what this means, how the heck do I get columns enabled, and how do I then get a size column? I would love to have columns in general. But all I see if filters at the top of my inbox and attachments is there but I am not able to rank them by size.

On Windows 10 I'm using Thunderbird with a Juno email account (POP.Juno.com). I want to delete messages in Thunderbird without deleting them on Juno server.

I have checked "Leave on Server" but I think that applies to downloading messages to Thunderbird.

Also, it seems that we can delete messages on Juno, but that does not delete them on Thunderbird Thanks

I inadvertently downloaded the latest version of Thunderbird. I wish to change the Inbox view to the old version where above the: From. Subject. Recipient. Date I can have: Write: Delete: Get Messages: Mark: Reply: Print: Backwards: Forward: Address Book: How can I change the look of the new site which is not easy to navigate to my old look, If you are a none tecchie this is not easy to do.. Any Help will be very welcolme.

Best regards Sport

I use both gmail and hotmail with Thunderbird. When I send a Hotmail message, the recipient's inbox shows the note came from gmail. So, when they respond to sender, it goes to my gmail account. Is there a way to fix this ?

When I send an email to a mailing list, using a gmail address as sender, Thunderbird does not download a copy of that email. This was NOT the case when I used non-gmail addresses. This is highly inconvenient because my participation in a thread is not shown, other than that which is quoted by a respondent. Those emails are present and being shown in my gmail webmail site.

This problem is present in two different accounts. All of my gmail accounts are configured as Imap.

Resolving this would be very nice. Thanks

Problem: Thunderbird hangs up on Macbook and iMac. It opens to the normal view, but if I try to do anything, I get the beachball of death. I used Mac migration assistant to install from Macbook to iMac. Before the installation, the Macbook Thunderbird worked fine, but after the installation, neither worked. My PC installation works fine, as does Apple Mail on my iOS devices, so it is not a provider problem.

Solutions tried: restarting in troubleshoot mode, restarting iMac, turning off access to Apple Contacts, turning off antivirus (Norton), creating new profile and copying existing mail data into the profile folder, and renaming various files in the profile folder.

Results: None of the solutions I tried provided access to my email. I can open the new profile, but that requires that I reenter all my email account information and copy the emails for each account into the new profile (I use POP). The problem may be with the prefs.js file, since if I rename it, Thunderbird doesn't hang, but would require me to reenter all my account info as if it were a new profile, and all preferences would be lost.

Question: What is the best solution for this problem? Is there anything that would work better than reentering the account info -- e.g., can I make any changes to prefs.js using a text editor or some other utility?

I want to export mails only of a certain mail account (I have got 6). I would like not to export ALL accounts in ONE zip file but I want to have different zips. Is that possible? Why do I want that? I am active in 3 different organisations and I have a private account and - it can almost not be avoided - a google mail account. So when I look for a certain mail I know which zip I have to import and to look for it. Years ago I used MS outlook and I had the possibility to create archives as defined for each account and - if necessary and wanted - for each year. Is this also possible in Thunderbird? If yes HOW? Many thanks in advance!

I have two computers, one older with TB 115.9.0 32 bit, pop. The other has 115.9.0 64 bit, imap, same email address. I have tried to merge them, but when i do the Thunderbird Import folder has zero messages and no subfolders. I also tried changing the old TB to IMAP, didnt work: "configuration problem". Any help would be appreciated.

Is there any way to select other than the "home" calendar as standard? Have tried to change order in the calendar setting, but when I accept a meeting invitation it always place the meeting in the home calendar. I would like to select the syncronized Google calendar.

The syncronization with Google calender works perfect when manual enter something.

Best regards /Mike

I normally open messages in tabs under exactly one circumstance: when I right-click on a message and explicitly open it in a tab.

I've found that (until I changed the handling of PDFs to "Save file") any PDFs that opened using Thunderbird's preview function would reopen if I closed and relaunched Thunderbird. This is not desired behavior.

I will also note that if I open Settings, it opens in a tab, rather than a separate window. This is neither expected nor desired (and my natural reaction is to click the close button on the window, closing Thunderbird, because "Settings" is something I expect to be in a window, not a tab. And that, too, reopens if I reopen Thunderbird.

And worst of all, those tabs that shouldn't be reopening at all are reopening in front of the main tab.

There was an extension called "Thunderbird-DontRestoreTabs," that would do exactly what I want, but that was made obsolete when the underlying extension technology was deprecated, so it is of no use in 115.9.0.

Hi, I have used Thunderbird for many years and always liked it. I would like to know is there a way to tone down the brightness of the white message pane in email ?? It is very bright and glaring. Any white anywhere else I go is just fine. Thank You,, Banyarola

Hello and thank you for your help, I am trying to find my old Mozilla Thunderbird, e-mail account my older computer does not work, anymore, I have not used my Thunderbird, e-mail account in over five years, because I am on a newer computer.

My old computer does not work and Thunderbird Email is a great program. How could I get my old emails back? And working. If you could please give me more or less a time, and date, to wait for your response, so I can wait for someone to help me, and not lose that opportunity. It would be much appreciated, so I don’t miss contact with someone that can help me with this matter. I am in the East coast. And thank you for any concern in this matter please help.
