Hi, I am retired, but it does. not mean that tb shall be useless. Used to be simple and to make messaging easier. Now it is opposite.

When replying to a message, I want to change font of what my friend have sent me. Color picker does not work. I press the square, picker appears, I select the color, it appears on the picker, I click ok, and close. Nothing happens. Nothing happens, Nothing happens. I repeat, and it shows black as chosen color. I chose red. There is no way to select and use the color. Some time ago, someone wrote that it kind of works. Kind of works. When you choose color, you must not use it, but close the color chooser. So far, nothing works. It is handy to change the font color but it does not work. But if it works, who knows how to use it. NOt intuitively at present.

Also when the message arrives, I have no clue that it has. It does not indicate on icon anymore. But when I open the tb, i can see on one or another account so many messages new, unread, but am struggling every time to find them out. So far, I have to search every time again and again to filter only unread.... This makes tb very difficult to use rather than easy. Can't you make a simple version of tb without a million of useless to me features. I want to have an access as used to be to all email and in an instant to be able to see, not search the new ones? Is it impossible? Thanks. Michal

Gmail is connected. Deleted letters in the trash have stopped loading. I haven't changed the settings. I just went in today, the folder is empty. If you go directly to Gmail, all the letters are displayed.

I'm still running Windows 7 (it works for me) and Thunderbird (version 115.16.2 (32-bit)) has been my e-mail client application for many years.

Inside Thunderbird I have a series of sub-folders (which I shall refer to as 'folders') named & arranged by years & months.

Any received e-mails that are 'personal' (i.e. not news items, previously OK'd advertising, or junk) get filed into the current month's folder (which is 'inside' the current year's folder). (Towards the end of a current month I create the next month's folder.)

I used a wired USB mouse with two buttons ('left' & 'right').

When things are working like they are supposed to (and I have received a piece of personal e-mail that I want to store) I 'left click' on the e-mail (in the 'inbox') and (while holding the 'left button') 'move' the e-mail into the current month's folder.

(the 'problem') Once in awhile I accidentally click the 'right button' during the process of moving an e-mail from the 'inbox' to the current month's folder.

To-all-appearances the e-mail 'disappears' though a few times I have found it in an 'adjacent' month's folder (I also look in the 'trash' folder').

So far my only 'solution' (I at least have a copy of the message) is to go to my e-mail server (I have it configured so that it does not automatically delete messages) and 'forward' the message to myself (in which case I am shown as being the 'sender' when the message arrives in the Thunderbird 'inbox').

(my question) Does Thunderbird have an (undocumented ?) 'disintegrate' action ... where a message can be completely erased as a result of an accidental right mouse button click ... or is there some other folder where I should look (other than 'adjacent' month's folders and the 'trash' folder) ?

I´ve been donating and hoping for a IOS mobile version of Thundirbird for several years now, is there any info regarding the release for iphones?

Thanks in advance!

Recovery of thunderbird forced change of message structure. Old tried and true layout became irrecoverable. Install phase of new thunderbird is not the time to go dicking around with the existing data structures. (which you yourself decided on ages ago).

How do I roll back the unwanted "upgrade" of thunderbird ?

Thanks,

Please forgive a very basic question. I think I know the answer but would appreciate having the correct one from the pros.

My wife and I each have Thunderbird installed on our computers. While we each have individual email addresses, we also have one email address we share, and we access it via Thunderbird.

If I'm marking certain messages as junk on my computer, will that designation only apply to my computer or, because of the common email address, will it mark those same messages as junk on my wife's computer?

Thanks for any help with this.

On Windows 11 when I try to set up two accounts for two separate users on the same email server I get an error. When I do the same on Windows 10, it works as expected. Both Windows have the exact same versions of Thunderbird. Why should this be? Can I do something to get it to work? I will provide any additional information requested to get at this.

I have a Google hosted domain email address. I've been using Thunderbird for a long time and I'm familiar with the problems of Gmail and Thunderbird not playing 100% nicely.

With that said, I have an 80+GB "Sent Mail" folder and I need to bring that back down to what the actual size is.

Any insight on the most efficient way of doing this?

I'm in the process of cleaning up Thunderbird e-mail before moving to a new computer. I started with 11,593 e-mails in my Inbox and 7,799 e-mails in my Sent folder. I'm now down to 7,634 in my Inbox and 4,965 in my Sent folder. I've allocated 2 weeks for this process and found that it's taking me about 3 hours per day to meet my daily goals. I'm finding that I'm spending at LEAST half the time responding to "Empty-Trash/Compact-folders" requests. There are times I can delete 50 e-mails at a time without getting a request. Other times I will try to delete ten e-mails and get the request. With the old version of Thunderbird I could literally delete hundreds of e-mails at a time. Can you help? Russ Bukwa Yardley, PA ps. I have intentionally given you specific numbers. Based on my software- and test-engineering experience, I speculate you need to create a stress test to solve this nagging problem.

Thunderbird 138/139, Windows 11 Pro 23H2. While composing a message, after a few lines the app freezes. Both the compose window and the main TB window freeze. Only opening the Windows Task manager allows me to close them. This did not happen with earlier versions.

If I save the message every few seconds while composing I can get most of the message back and continue after restarting TB. This behavior is the same in both the normal and troubleshooting TB modes. I can't even find a crash log to send to Mozilla.

Where shall I look next?

Thank you!

Since 5.18.2025 I get a "no message found" in my sent folders and other folders. "Find" will still find the messages and they can be opened, but I can't get the email folders to display. I know they are still there. Version 128.10.2esr. How can I get them to display in the folders?

We are trying to create an out-of-office response email and have found an issue. When creating the filter to respond with, the "Reply with template" option under "Perform these actions" is missing. We have checked the usual reasons why, but we cannot find what the problem is. We are using an Imap account. We have the 139.0.2 version of thunderbird, and we have set up the template necessary for the response without any issues. What could be the solution?

I have two issues that are related to a buggy interaction between Thunderbird and Microsoft's email server.

Issue (1) When I send an email with my Outlook email address (from the Android app or from outlook.live.com, but not Thunderbird), my email address shows up as a jumbled mess in the sent folder on Thunderbird.

It appears to the effect of

IMCEAEX-_O=FIRST+20ORGANIZATION_OU=EXCHANGE+20ADMINISTRATIVE+20GROUP+XXXXXXXXXXXXXXXXX+29_CN=RECIPIENTS_CN=XXXXXXXXXXXXXXXX@sct-XX-XX-XXXX-X-msonline-outlook-6f06c.templateTenant

(I have masked some potentially sensitive information).

In the sent folder on my Outlook Android app, my email address looks normal. It also looks fine on a browser in outlook.live.com. However, it's in the sent folder on Thunderbird that my email address is a mess.

Issue (2) When my Outlook email address is involved, the sending and receiving email addresses in the "correspondent" field are swapped in Thunderbird.

There are a couple situations where this swap happens:

1. Sending an email with my Outlook email account (either through the Android app or outlook.live.com, but not Thunderbird). In my Outlook sent folder on Thunderbird, the "correspondent" field shows my jumbled email address and not the receiving address, such as bob@gmail.com. Likewise, In the inbox of the receiving email account (such as bob@gmail.com) on Thunderbird, the "correspondent" field shows bob@gmail.com and not my Outlook email address.
2. Sending an email with any other account in Thunderbird to my Outlook email address. In my Outlook inbox on Thunderbird, the "correspondent" field shows my Outlook email address (this time unjumbled) and not the sending email address. However, in the sent folder of the sending email account in Thunderbird, the "correspondent" field shows up correctly (i.e., my Outlook email address).

These two issues are perplexing and probably related. Thank you for any help!

Hello!

We use some filters in thunderbird to manage messages redirection to other mail-boxes. When message body contains any image, it disappears after redirection via filter rule.

When you forward same message to the same person by hands - works great, nothing is missing.

Can you help with any suggests / advises for thunderbird client config to fix this?

We use Thunderbird 115.5.0 (64-bit).

Thank you.

Hi there,

I've recently had a problem with a couple of client PCs where their Thunderbird profile folder has grown to fill the entire hard drive. In both cases, the relevant account folder in the profile's ImapMail dir had grown to over 300Gb. This account takes up 45Gb on the server (where I'm running Dovecot with maildir storage). In another case on both PCs, an 18Gb account had grown to over 90Gb.

Both client PCs are running up-to-date Thunderbird (139.0.2 64bit), one under Windows 10 and one under Windows 11. Both had auto-compact set, with the minimum saving reduced to 100Mb. Both problematic accounts are shared accounts that use a deeply-nested folder structure. In both cases, I was forced to delete and then recreate the these accounts in Thunderbird.

I'm an experienced sysadmin who is also running the mail server, so I am able to provide any extra info needed. Additionally, I accept that these are large email accounts; I'm in the process of setting up an email archive system for the client using Piler. I have read many other reports of outsize Thunderbird data folders; these are usually referring to less than 20Gb. The problems we're having seem to be an order of magnitude larger!

Thanks in advance, P.

I have set my account to "Don't delete any messages", because I frequently want to reread a deleted message in my Trash folder. However, when I go into my Trash folder to search for a deleted message, I am finding that messages older than a certain date have disappeared, although I've done nothing to permanently delete them. For example, today everything older than May 3 is gone. What can I do to prevent this?

thanks, CW

I've downloaded the program to a second computer and put in my creditials and it's giving me an error "unable to log in at server. Probably wrong configuration, username or password." I've entered the correct info. Help
