I have have had a Gmail address for a few years and have just created a new Gmail address, I am trying to copy about 20,000 emails from the original Gmail IMAP folders to local Thunderbird folders as a backup, and then copy them to the new Gmail address IMAP folders.

I have tried copying these in smaller amounts as suggested (between 200 and 500 at once) This seems to go well, however, when I have completed the task the original folder has a much higher amount of messages in it than the new one, so some messages are being lost along the way.

Is there a reliable method to do this, such as closing Thunderbird and then copying and pasting data held in the profile folder, or does it need to be done with Thunderbird running?

Many Thanks in advance

I have the latest 128.13.0esr (64-bit) Thunderbird running on Kubuntu 24.04.

I have several Thunderbird installs with over 10 email accounts on each. When I am in one accoujnt I cannot click on the inbox on another account. I have to first click a subfolder such as Drafts and then I can click on the inbox.

To repeat this open T-bird and a profile with several email addresses. Click on Inbox in one. do something. Then click on the Inbox in another acocunt. Nothing happens. Then click on Drafts or Sent and then on Inbox and you are in just fine.

Hi all! I use Thunderbird with my company Outlook, and recently I've been having an issue of some emails being deleted, but not moving to the trash. I can still delete other emails, but these eight or nine specifically still show in my inbox. When I try to click on them, the subject and sender in the viewer shows whatever email I was looking at previously, but the message itself is blank. I've tried every way of deleting them, but nothing seems to be working. They don't seem to have anything in common, like having a certain attachment or being from a certain sender. Any help?

Hello, I received an email from Spectrum (.TWC) that I needed to change my password by Nov. 11th. I did change it last evening. Now today I cannot receive my email via Mozilla Thunderbird, I receive the pop up to Enter the Password when I open it. Can you help me with this. Thank you for your time and efforts.

Hello:

My Windows Thunderbird has become unresponsive, taking forever to connect to my various accounts. I suspect the problem is with my GMail account--which is not my primary account--is causing the problem, but I am unable to un-sync GMail's All Mail folder.

I was able to get into troubleshooting mode, but TB was still unresponsive.

I have copied the profile in question to my Linux machine, with TB V140.4.0esr, to try to repair the profile, but the problem is recurring there as well.

Is there a way to manually edit the profile file(s) to remove the GMail account from Thunderbird?

Any insights would be much appreciated.

Thanks

For many years now I have had several email accounts 'share' Thunderbird's Global Inbox (Local Folders) and this has worked fine (by the way I'm using POP throughout).

For a long time I have also had a separate email account (call this account A) using its own Inbox. Again, all has been working fine.

Very recently I created a new account (Account B) and directed this to use Account A's Thunderbird inbox (via Account B's Server Settings, Advanced...) and selected the "Include this server when getting new mail" option. All looked fine at that stage (I did not think to go back and check Account A's Server Settings, Advanced...). Under Account B's Copies and Folders I also directed Account B to use Account A's folders.

As I expected, Account B did not have any of its own folders created.

On selecting Account A in the folder pane and checking for emails (via the Get messages icon at the top of the folder pane), only Account B was checked (as evidenced by the status bar messages scrolling through at the bottom of the window). This was most perplexing - had I somehow lost a whole bunch of messages that I knew should be sitting in the inbox at the mail server?

However, I soon found the culprit. Account A's Server Settings, Advanced.... were completely greyed out (and so effectively disabled) - see image attached.

So setting up a 2nd email account to download to 1st email account's inbox disables downloading of 1st email account's inbox messages. No warning of this is given - it just happens behind the scenes.

Is this all a conscious design decision (and, if so, why?)? Or is it simply a bug? Is there a solution / workaround?

Just to be clear, selecting or not selecting "Include this server when getting new mail" option has no impact on this one way or the other - it is the attempted sharing of the inbox that gives rise to the issue.

I recently downloaded Thunderbird. Due to comcast transfer of email to yahoo, I now have a yahoo account with a comcast email address. Using the export.mail.imap.yahoo.com incoming server, I was able to get all my mail into Thunderbird. At some point, I was asked to compact my folders. I replied yes. After that there were only 2000 messages in my inbox. To recover, I had to change my settings for my email address to an incorrect one and then back to the correct address. That started the rather lengthy import process again. My inbox is 3GB. What went wrong and how do I avoid this from happening again?

I have to add a office365 accounts. Everthing works, until Microsoft's popup window requires to sign in to MS 365.

When I click in "Sign In", nothing happens. The button becomes light blue for some seconds, then turns back to blue again.

The credentials are correct, there is no error message, nothing.

Probably a problem with the popup browser window?

Javascript is enabled. Anything else that could break this?

When replying and using inline comments, any backspace gets turned into a carriage return at the end of the message. If you backspace over the first letter of your reply it throws you to the end of the message.

When I compose email messages, I want them to be plain text only. In older versions of Thunderbird, this worked fairly well, but in new versions, even though the message is sent as plain text, it is not the same text that I type into the editor.

For example, if I begin a line with "> " (greater-than space) to indicate a quotation, Thunderbird will add another space at the beginning. I once tried to send "-- " (dash dash space, a signature marker) in a message, only to find that Thunderbird replaced the space with a non-breaking space.

I didn't ask for that. I want the content of the message that I send be exactly what I type, nothing more, nothing less. No reflowing, no subtle character alternation. Is there a setting to disable those mis-features?

I copied my profile because I had to reinstall TB. When I copied it back, I got all my emails but not my address books.. How can I get these back? Also, I got my emails back but it didn't include the number of each. How do i get these back?

I've been searching for a few days for a solution to Yahoo Mail not downloading to Thunderbird, I've seen other people with the same problem, I've tried different solutions, but at this point I've given up. My Gmail is still downloading but I have to check my Yahoo Mail via a browser. What gives? Why did this happen in the first place?

I have Windows 11, I've updated Thunderbird.

Upgraded from Windows 10 to 11 a couple months ago. Since then, TB freezes nearly every time I am composing an email. "Help About" says TB is up to date. Remedies? Or do I have to wait for a new version?

Every time I want to print an email, the default copy number on my printer menu is shown as 2.

I don't know how, when or why this change [from 1 copy to 2 copies] happened.

I wish to 'reset' the default copy number to 1, so I don't accidentally print a second copy and waste ink, etc.

When I want to print documents stored on my PC, the copy number field on the printer menu is blank, allowing me to enter the number of copies I want - so the issue appears to occur only when I print emails.

Hi

I work in a small traditional community fishmonger shop in Scotland and we use Mozilla. I am trying to find a basic instruction manual i could print out handy for us (we are a small team and only i have experience in Microsoft emails etc but this is different ) and i am just trying to help us understand some basics priority being for email, contacts and folder daily management.

We receive a mix of online orders, customers, suppliers and much “junk” noise emails so i’m trying to help us figure out simple and easy to set things moving forward after some staff changes that impacted our “flow”😊

Any tips would be much appreciated 🙏 Thankyou Danna

Right after typing my email address and pressing "Continue", Thunderbird crashes. I wanted to give it a try after many years of not using it, but then it crashes right at the start.
