Dell windows 11 computer self destructed and crashed hard. Lost Thunderbird emails but have an Acronis cloud backup. Have purchased a new Dell EBT 2250 computer with windows 11 pro.

QUESTION 1: What are the proper procedures of installing Thunderbird and recovering my past "stuff" which was located at C:\users\My-Username\AppData\Roaming where Thunderbird kept my email data..If I install Thunderbird on the box, it would create that structure to create the Thunderbird data folder.

QUESTION 2: What are the proper procedures in recovering Thunderbird past data before I open it to my email server (Yahoo) where I have directly been maintaining my new emails via browser. I was going to install Thunderbird, then replace the Thunderbird folder under the user/username/AppData/Roaming, but when installing TB forces you to give an email account and P/W to log into your email. I do NOT want to have the email at Yahoo brought down before I can confirm I have restored all my past emails from my backup Thunderbird fold.

Question 3: Is there a way of installing TB in order to get the structure it uses, then overlay the TB structure under my user id?

I didn't want to restore my new Desktop with the OS recovery method because of the completely different hardware that OS would encounter once it tried to come up under a completely different hardware environment.

Thanks to anyone who can help me in what I should do, Floyd Smith

For two days I'm having intermittent "hanging" when I'm typing a document or letter in Thunderbird. It has just dont that for the 2nd time in less than 10 minutes. Don't know what's happening but it's very frustrating. Am not having any other computer problems. Am running Windows 11 which is automatically updated by Windows. I think Thunderbird is the most current version too. Help please anyone! It does say "(Not Responding) at the very top of the page.

Greetings, I've been using Thundrbird for many years, and now suddenly it won't open, because of a "Bad Image" error. Is Mozilla Thunderbird still usable on Windows 10? This started happening either yesterday (maybe yesternight) or the day before yesterday.

"--------------------------- thunderbird.exe - Bad Image

C:\Program Files\Mozilla Thunderbird\lgpllibs.dll is either not designed to run on Windows or it contains an error. Try installing the program again using the original installation media or contact your system administrator or the software vendor for support. Error status 0xc000012f.

OK

Couldn't load XPCOM.

Should I try to reinstall the newest version 150.0.2? I have downloaded it, although I just checked the file version, and it's already updated.

Thank you, Shalom

Recently started getting many more mails than usual. many if not all related to setting up an account at a site from which I had not solicited an account. some included requests to acknowledge charges to my account for purchases I had not made charged to payment accounts I did not have. Some I could not read because they were in languages I did not read. My usual practice is to read and then delete emails that I don't need, but the ones I am receiving are so numerous, reading each and then deleting is impractical. I need some way to delete by categories. I don't understand what is causing the flood of emails but I need to stop it if I can. Hidden in the emails I am getting may be some I need and if I delete by categories I may lose some that I need, but at the same time, it is impractical to read and then delete individual messages. mails Anyone have any idea what caused the flood of what appears to be spurious emails, is it some sort of scam or cyber attack?

I am trying to add an email address to thunderbird it is an outlook email address [edited]@outlook.com I have checked the address and the password and both are correct however thunderbird says that the configuration is incorrect and will not accept it. also I have it open in another browser window will that cause problems ?

I want to install Mozila Email on my Windows 10 Laptop and want not to use the default version 150 but version 142. The support still downloads version 150 when I choose verso 142. What can I do to correct this?

I am using Mail Merge to send messages, and want to have the date in the body of the message change to the date I actually send the email. Or I have a draft email that I eventually send. Is there a field that will insert today's date (to compensate for me forgetting to change the date manually)?

Unable to add personal Hotmail/Outlook.com account via IMAP with OAuth2 Hi, I'm unable to add my personal Microsoft account (@hotmail.com) to Thunderbird via IMAP despite trying every solution I could find. My setup:

Thunderbird (latest version), macOS Sequoia 15.6.1 Account: personal @hotmail.com

What I have tried:

Manual IMAP configuration with both smtp-mail.outlook.com and smtp.outlook.com as outgoing server OAuth2 authentication — the Microsoft login window opens, I successfully log in, but Thunderbird still throws "Unable to log in at server" Enabled cookies for all Microsoft domains (outlook.com, login.live.com, login.microsoftonline.com) in Privacy & Security settings Enabled 2FA on my Microsoft account and generated an App Password, then tried with Normal password authentication — same error Toggled the experimental Account Hub off and on, tried both the new and old account creation flows Restarted Thunderbird multiple times between attempts

What works: My institutional Microsoft 365 account (@hnu.de) connects and syncs perfectly with identical IMAP/OAuth2 settings. The issue appears to be specific to personal Hotmail/Outlook.com accounts. Has anyone successfully connected a personal Hotmail account recently? Any help is appreciated.

I have a new gmail account and I can't figure out how to get Thunderbird to show me messages that come in to that address. I changed some things trying to set up a second account but emails still don't arrive. I am using a desktop computer with the most recently updated Windows 11 and updated Thunderbird too. What am I missing?

I have installed Mozilla ThunderBird Previously on many machines. Am Familiar with Incoming Email Servers and OutGoing Email Servers ... Also special ports ... POP ... and .... SMTP ... IMAP ... ETC ... GBGB On this Machine ... Dell Latitude ... 128 GB SSD ... 8GB RAM I have Mozilla ThunderBird Installed for as Single Email Account ... OverstreetENGR@Juno.com

When I REPLY to Emails , THIS IS the error message that I get : Sending of the message failed. The message could not be sent because the connection to Outgoing server (SMTP) smtp.juno.com timed out. Try again.

There is a message in my Inbox that cannot be deleted or moved. I've tried re-starting Firefox several times to no avail.

The stubborn message is actually completely blank when viewed in Tbird. Also - the stubborn message has already been moved to another folder where it can be read (i.e. message contents available). Yet - this stubborn "ghost" mail message will not disappear from my Inbox!?

I am connected to an Exchange email server - one of the "shared" servers administered by Microsoft.

I had hoped to get away from the insanity of Outlook, but it seems when it comes to email, there is no escape!

And finally FWIW, When I view my Inbox in "Web Outlook", there is no "stubborn ghost message" in the Inbox - the message is where I moved it.

Thunderbird administers my 7 "aol" email addresses (accounts) on my Dell laptop (running Windows 7). 5 of the accounts are behaving normally, but the other two accounts appear to be linked. So, when I send an email from one of them, it appears in both "sent" folders. When I receive an email in one of them, it appears in both "in box" folders. When I visit "mail.aol.com", these 2 accounts behave normally. So it appears that they are linked within Thunderbird. Can you suggest a possible solution? Thanks, Tim

When I delete mails they remain in the Gmail All Mails folder. I have set the setting to move deleted messages to Trash (attached) and I always Empty the Trash manually. In All Mail all the deleted mails are present. In the attached screendump from Gmail webmail it is the mails without any labels in front. (I have unsubscribed to All Mails in TB, but previously these messages would show up as only present i All Mail when searched in TB). Is there a synchronization problem? I have noted that there are two Trash folders in Gmail webmail: 1. in:trash (where Gmail webmail is putting deleted mails which do NOT show up in All Mails) and 2. label:[imap]-trash (where TB is putting deleted mails which DO show up in All Mails). Is that the problem?

Additional question: is there an easy way to permanently delete the mails without label i All Mails?

First I am very frustrated that someone decided to change the default to show all messages in threads. How do I globally disable this for every profile on my system. Additionally how do I disable it in one pass for all top level folders at the moment I have to change one top level folder at a time on every system I use thunderbird on, as I have over 100 folders this is very inconvenient. How do I modify a new thunderbird installation so all users and profiles default to threads being turned off.

Hi, I’m having a recurring UI issue in Thunderbird with the toolbar above the message preview pane.

After some time of using Thunderbird, the area between the message list and the message preview becomes visually corrupted. The toolbar where the Reply / Reply All / Forward buttons should appear either disappears completely or turns into a broken/glitched gray bar.

I attached a screenshot showing the problem.

What I already tried:

Restarting Thunderbird Starting in Troubleshoot Mode Disabling all add-ons Resetting UI/customization settings

These actions help only temporarily. After some time, the issue comes back again.

Additional info:

Windows 11 64-bit Latest Thunderbird version The problem seems random, but happens multiple times per day It affects usability because I lose quick access to reply buttons and message actions

Has anyone experienced something similar or knows what may cause this? Humanity invented email clients 50 years ago and somehow we’re still fighting disappearing buttons like it’s experimental Soviet software. Beautiful continuity of civilization.

Thanks.
