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 am using the latest TB build, 144.0.1and have only the British dictionary as an extension, no themes.

Occasionally TB will hang when launched and the Windows event viewer will show this....(added image)_

The friendly xml log within the event viewer...

AppName thunderbird.exe

 AppVersion 144.0.1.0 
 ProcessId 0x6234 
 StartTime 0x1dc51956edcf231 
 TerminationTime 5 
 ExeFileName C:\Program Files\Mozilla Thunderbird\thunderbird.exe 
 ReportId f3ad169f-c629-4357-85ae-7db29d0541f1 
 PackageFullName  
 PackageRelativeAppId  

HangType Cross-process

as noted, this only happens when the email client is launched and will not happen each time. I have tried without the dictionary, as it is so random it can take a while to occur, but that does not seem to make a difference.

I am using Windows 11 25h2

Thanks

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.

Hi there! The reminder function for termin (for example three days before) doesn't work anymore, but before it works allways. I couldn't find the reason therefore.

since Oct 31 Thunderbird has not been able to connect to AOL / verizon email server to receive emails. I made no changes. I am able to send email so the connection is good that way.

Message is "login to server pop.verizon.net with user name xxxx failed

Send and receving on phone works ok

For some reason after the last update I have been getting multiple inbox.conf(*) folders getting created (see image). I have not found a way to remove these folders. Is this a bug or a setting issue?

Six emails I received on 11/3 had their body content totally replaced by a photo contained in an unrelated year old email I had received. Both immediately before and after, all is working normally. I don't know what caused this, nor could I find any way to recover the missing content.
