Hi, Win 10 Pro new installation. Dell Optiplex MBR type Bios.

I had saved a recent profile to an external drive in its own name (i.e. not the profiles folder)

After the new Win 10 installation, I downloaded a new copy of Thunderbird.

I then copied the saved profile into the new Profiles folder, selected it in Choose user profile and started Thunderbird.

Thunderbird opened but not with the saved (8+ Gb) profile, just one new email account and asking for passwords to other email accounts I used before, and no folders.

I went back into the profiles folder and renamed all other profiles "OLDxxx999, but still the same one new email account when I opened Thunderbird.

I desperately need the saved email folders - I don't mind loading all the email accounts again, just need my court case history folders.

How can I force Thunderbird to use the saved profile, or can I identify and individually load in the saved local folders?

Thank you for any guidance towards a solution.

The Local Folders Account has a setting to set the Message Store Type. By default it's set to "File per folder (mbox)". How can I switch to Maildir?

Note that in global Settings, I have already set up the Message Store Type for New accounts to "File per message (maildir)". But I can't create a new local folder account.

My hosting service caused me problems and are no longer available I have changed to new host, simply changing only the settings to connect to new host, same imap, port settings but now locally stored messages are no longer visible, I know they are stored on my system under /home/jim/.thunderbird~ but is there a way to retrieve them?

Hi, My Thunderbird email has stopped downloading emails from my server. I click to download emails, get a message saying "downloading 1 of 25" but no progression from here onwards. No messages are downloaded. I have made no changes to the settings and it has been working well for many years. wifi is connected.

Thank you for help to restore this.

• After the update launching thunderbird daily, from anywhere, main `.exe` or shortcut links
• It opens a cmd prompt, I am using Windows 10 build=19041, I also use `windows terminal canary`
• I had no issues before the recent update, is there a way to roll back the version? to the previous commit?

I am new to Thunderbird and needed help to import my contacts from Outlook. It wasn't easy; I had to reorganize the CSV file to match Thunderbird's format - what a pain. Then I needed to recreate all of my group addresses using Thunderbird's tools. I used some of these newly created group addresses a few weeks ago. Now all of the group addresses exist, but they have no members. What could have happened? And, what should I do to recover their contacts?

Thank you, Stephen Thompson

Older messages in Thunderbird are listed but their content is not showing. I have been using TB forever and I never had that problem before. It is POP3. When I try Folder Repair, the program simply throws out all messages whose content is not accessible (so if my Sent folder has 40,000 messages it comes back with a Sent folder of 2,000). Clearly something got corrupted but I am not sure what. In the picture below, the header is visible but (a) not clickable (different header showing) (b) no content is displayed. I used to copy the content of the TB folder to my laptop and back (while keeping different profile names assigned during installation. The problem seems to have started when I changed profile names and began using identical profile names on both the desktop and laptop. Also, the total size of the folders is around 65Gb, in case there is a size limit. Any ideas? Thanks

Hi, I have a problem with Thunderbird tabs. I have some emails open, but after some time these emails disappear and I am left with tabs without title or content, why?

Tag names can be changed via message > tag > manage tags. But how can I change the tag ID ?

Let's say for example, I want to change the tag ID "unreplied" to "needsreply".

steps:

1. in user.js: change user_pref("mailnews.tags.unreplied.tag", "unreplied"); to user_pref("mailnews.tags.needsreply.tag", "needsreply");


2. search&replace all instances of regexp ^X-Mozilla-Keys:[^\r\n]+unreplied in all .eml files


3. Some tags are not stored as "X-Mozilla-Keys" inside the .eml file but elsewhere ( https://forums.mozillazine.org/viewtopic.php?t=3123346 ) – I suppose in the .msf files. They are in Mork format. Can I run a search&replace on them or will that break them?

Are these 3 steps enough or is more needed ?

Whenever a new message is received, which should go to the Local Folders\Inbox, instead a previous email from 2 days ago is always shown. I have recreated new emply Inbox and Inbox.msf files, but to no effect. Any suggestions on how to fix this?

Hi,

I'm experiencing issues with threaded view in Thunderbird (version 139.0.2 on Windows). Some threads do not display all messages -only a few emails are shown (e.g. 2 out of 8), and others are missing from the thread view even though they are present on the server. Rightclicking a message and selecting "Open message in new tab" sometimes works (but still doesn't show all messages), and sometimes it doesn't open a new tab at all. the missing messages do exist on the server, and I can find them using Ctrl + Shift + F , but they do not show up in the thread, nor do they appear via Global Search, even though the global index has finished building.

I have tried the following: -Right-click folder > Properties > Repair folder -Deleted and rebuilt global-messages-db.sqlite (global search database) -Reduced IMAP mailbox size from 140GB to 110GB -Waited for reindexing to complete

But the problem persists. It seems that Thunderbird either doesn’t associate all related messages with the same thread, or skips them entirely in display and search.

What can i do to fix it? Thanks in advance

I am using MacOS 10.13, Thunderbird 115.15.16ESR: my Hotmail worked until 15 May 2025 and then it would not download new emails. Screenshots are available if you want me to post them. I got an error message: "authentication failure while connecting to server outlook.office365.com". I updated Thunderbird to the latest for my OS: 115.18.0ESR. Still no new emails. I deleted my email account on Thunderbird and tried to reinstate it. Now I get an error message when trying to set up the account: "Unable to log in at server. Probably wrong configuration, username or password." I tested my password by logging into my Microsoft account with it on my browser. I can also login to my email using Firefox, but I want my Thunderbird email client to work again.

The configuration I am using is: I use my normal hotmail password in the password field. I also set up a new App Password with Microsoft and tried that without success. With the 115.18 update there is a new field: Your login. I just put my hotmail email address in here. incoming: outlook.office365.com, port 993, SSL/TLS, Oauth2 
outgoing: smtp.office365.com, port 587, STARTTLS, Oauth2 (I have also tried: smtp-mail.outlook.com)

I enabled 2-step authentication with Microsoft in my Microsoft account more than a year ago. Interestingly, I don't get a prompt on my iPhone Microsoft Authentication App when I select Done when trying to set up the hotmail account on Thunderbird.

Please help. I am desperate, and I have wasted a lot of time on this without success. Cheers

When I search Messages (Ctrl+Shift+F) there used to be an option to select "Body" Contains [a text string]. But it's disappeared. The body of my emails IS downloaded and 'Keep messages in all folders for this account on this computer' IS checked in the Sync. and Storage section of Tools/Account Settings. So how can I get the ability to search the body back?

when i oppened tbird on windows 10, it showed a page to obly my for a donation. i had made a donation short ago, but eventhough, i just made another one time donation. when i open tbird again, i can not get out of the donation page. what should i do please???????

Not sure what has changed, but I have a lot of sub-folders in my email handler, I've set up filters and generally, the incoming mail get through the filters and ends up in the correct sub-folders, but today, I've been trying to add one sub and it fails. No message, no error. Just no sub-folder creation. Did an update do this to me? And others?

My desktop computer died, so I needed to copy all my data files from backup (which worked fine) and then install all the apps that I regularly run on my laptop. When I installed Thunderbird, I got the latest Release 139.02. It behaves very differently from what I think is called the "Classic View" that was running on my Desktop. I REALLY hate it, but can't figure out how to set the Thunderbird parameters to do that. My problems include:

-- Overview of Thunderbird "Views". I can't find any documentation that explains [a] the various viewing options that Thunderbird offers and [b] EXACTLY how to set them.

-- Release Notes. I haven't found any release notes to explain when/why a major change to view was done.

-- Periodically, even for same release, Thunderbird CHANGES my parameter settings. Most annoying is changing the General Message-List settings to "Show Only Display Names For People in My Address Book". I live in a retirement community where many husbands & wives share the same Email address. With this setting, Thunderbird shows the name associate with the first message I received from this Email address. So the heading doesn't show which person actually sent it (although I can make a good guess when Thunderbird is telling me it came from a dead person. [g]

Is there ANY way I can get Release 139.0.2 to display messages the way I've been seeing them for at least 10 years? I REALLY need help. (If I can't get Thunderbird to behave the way I want, seem like I might as well switch to reading/writing messages directly from Google Gmail web site. It's equally lacking in documentation, but I suppose that eventually I could figure it out.)

Thanks in advance for any help anybody can offer.GMail, I'd seriously consider switch to using Gmail directly without Thunderbird.)

I'm aware of the many caveats regarding use of 'Repair Folder'. It's widely known that the results are...inconsistent, to put it charitably. Nevertheless...

I keep vast quantities of messages in local folders. For some of those folders, I manually archive the contents annually, by creating a new folder with the name of the year ("2025"), then dragging messages from the existing folder to the new folder. This sometimes works. More often than not though, it fails in one way or another. Sometimes I drag them across, a handful of them show up in the new folder, but then the rest just sit there in the old folder, in selected state, but with no activity taking place. Sometimes merely selecting smaller 'chunks' of messages to drag across will work. In others, such as last night, even that didn't work.

I then invoked 'Repair Folder' in a vain attempt at recovery; sometimes that will clear the issue. However, when I did this, what happened is that the chunk of messages that were selected wound up having all their date fields (in the display) reset to near the epoch - January 20, 1970. When I view the message source, the dates are correct.

I'm unable to find a way to recover from this.

Any advice would be appreciated.

Hi everyone.

Hoping someone may be able to help. I see that other users are able to fully highlight the events in calendar. I seem to be only able to highlight 2/3's (see image)

Thanks in advance

Tbird starts to d/l messages: "nn of mm new messages" counts up and just before it gets to the last few, it stops. It doesn't put the retrieved messages in the inbox or anything. Then it gives this error message:

"The DELE command did not succeed. Error marking a message as deleted. Mail server pop.mail.yahoo.com responded: Too many requests."

But this is POP mail, so delete request don't go back to the mail server. The number of emails deleted from the local db shouldn't have any effect on d/l... I'm mightily confused.

Yes, I did delete thousands of old emails. Still shouldn't make any difference for retrieving mail, nor should the client be overwhelmed by commands it successfully executed days ago.
