Thunderbird Support Forum

I've been noticing apparent duplicate messages within my unified folders inbox on my desktop recently.

Looking further I notice that one of my accounts has 'INBOX' as one of its subfolders which is where the problem appears to stem from. When I look at that account in isolation (ie not in unified folders) I can still see the inbox as a subfolder.

The subfolder 'INBOX' appears to be a duplicate of the account's main inbox (it contains the same number of emails), which may account for the appearance of duplicates.

At a guess this is probably related to inadvertent moving of folders. I find that when trying to use the scroll bar (to scroll down the subfolder list), if the mouse strays slightly to the left it will pick up a subfolder and move it unintentionally. This can cause all sorts of problems with disappearing emails and the folder structures showing differently on different computers.

In this case the duplicate email problem only happens on my desktop. On my laptop I can still see a subfolder named 'INBOX' but it shows as empty and I don't see the duplicate emails in unified folders.

It would be really useful if Mozilla could introduce a 'confirm folder move' feature as that would eradicate inadvertent moves.

How do I resolve the apparent duplicate emails on my desktop? I am somewhat reticent to delete the subfolder 'INBOX' for fear of the potential consequences. . .

I just upgraded to version 115.10.1 and I have since had numerous incidents where I could not move the cursor to add the next line etc. If I recall correctly this mostly happens after pasting text from a another email or other source. In fact there have been times when the entire composition becomes frozen. In this case it doesn't matter where you place your cursor, you will not be able to edit anything. Very serious problem and a major disappointment. I am always afraid to update at this point, and this is not right. The new releases need to be tried and tested.

Hi, like other users on this help service, I recently lost the ability to send smtp gmails on one specific gmail account, but receiving emails was OK. Every attempt to send brought a "send failed - enter new password" dialog box. I looked at a great number of "solutions" before I found one which almost worked, but I have modified/clarified it and post it here for others to try. First off, look at passwords in Settings, and check that you have an 0Auth2 password - very long and not anything you chose. Then go to Server settings, scroll down the left hand pane past all the accounts listed until you find "Outgoing Server (SMTP) and click on it. This lists your outgoing SMTP accounts. Highlight the one for the account which is not sending and click on "Edit" Change the authentication method to 0Auth2. OK your way back. Now go back to your displayed passwords and copy the 0Auth2 password from the incoming password box and paste it in the SMTP password box for the problem account. Now close TB and restart. When I did all this, it began to send emails again. Hope it helps someone else.

Thunderbird will not start. Message Can't Load XPCOM. Windows 10. Have uninstalled and reinstalled Thunderbird multiple times. No change. Have deleted the Thunderbird folder in Program Files and reinstalled Thunderbird. No change.

I cannot dismiss calendar invites sent to me from others on the Ubuntu platform. I can dismiss invites that I have initiated. FYI this doesn't seem to be the case on the windows release - I can dismiss "foreign" invites.

The only way to dismiss these invites is to delete them from my calendar (which I prefer not to do). Thanks.

In the attached screen shot they are two type of folders - One is yellow and looks like a paper folder and the others are rectangular in shape in different colors (here in res and purple) . I am unable to delete the rectangular folder that appear permanent and I don't even know how it was created as I used the same command "new folder" under the inbox or "new subfolder" under a yellow folder - I hope that this is clear : I want to delete the rectangular folders when needed

Whenever I open TB (115.10.1) new messages download. The problem is the newest message topic is in the Inbox list but it is hidden behind the column headings. I have to scroll the list down one message to see the newest message. Why is this?

I know i have asked this already but i did not receive an answer of a solution and id really like someone to help me with this. It is a duplicate question but again no answer and id really like one . i want to remove it please do not tell me toget a new profile and lose everything i have. there has to be another way

I deleted Thunderbird, than Installed latest version. Now in Thunderbird "Use Primary Password" is clicked so I can't reset primary P/W. Previous P/W doesn't work because there is no P/W there as far as I can see. Instructions I found: "Tools> Developer Tools> Error> etc. There is no "Error" button. Instead I get Incoming Connection (attachment) and an other screen that I don't understand. Can you help please? Thank you Ilio Pieroni

Now i do not want recreate a new profile and lose all my contacts book marks add on etc. how do i remove that yellow bar in Thunderbird mail

Hello Folks I recent times we had to migrate from one company to another as the former company no longer provided the emailing service... At first it worked OK...then I was no longer able to get emails and the new company took me through and reset Thunderbird setup,,,once that was done all my folder structure disappeared, and all the info stored in the folders... I have been trying to sort it out, but the company has not been able to do so...and today they suggested to contact Thunderbird to see if they could help... Thank you in anticipation Franco

""Description: COX Server Name: smtp.mail.yahoo.com Port: 465 Connection Security: SSL/TLS Authentication method: OAuth2 User Name: your user name, duh - Mine keeps changing the user name to the last name I put into any of my 6 accounts. The only way it will send mail is if the correct user name is in the correct account (obviously). Why is it changing constantly? click OK""

I've read the "fixes" from 2023 and they do not work for me. I tried changing the DESCRIPTION to blank, didn't work. Changed them to the corresponding e-mail for the account. Didn't work. Changed it to "SMTP" with the corresponding e-mail. Didn't work.

It keeps changing the last one I edit to the one I edited before it. It's driving me crazy. Won't send mail unless the User Name is correct (obv.)

Whole mess started when forced to switch from Cox to Yahoo recently. Seems to be working other than TB changing the name as soon as I type in the next one in the next email address and then it not working until I change the User Name back to the proper e-mail address of the 6 accounts.

I downloaded Thunderbird from Microsoft store. I enter my name, email and password. The first message was "Configuration found in Mozilla ISP database", but the last message was the Error: "Unable to log in at server. Probably wrong configuration, username or password".

Email is from gmail. App version is 115.9.0 (64-bit).
