I'm Using Thunderbird version 148.0.1 (32-bit) on Windows 10 Pro I currently have 2 email accounts in Thunderbird...a Gmail account and a private account linked to my own webpage account. Both these accounts are working very well and I encountered no problems when I originally set them up some time ago....... However.. I am trying to add an additional email account. a Live .co.uk account I enter my Full Name and email address "xxxx@live.co.uk" as requested... I enter my password for this account and in my "Your Login" details ( the characters "xxxx" before the @ in my email address) I then select "Continue"........... Response : "looking up configuration...." Then.... Authentication failed. Please check the username and password...Exchange auth error I know I have entered the correct username and password for this account... and the account works fine on my mobile phone email app. using the same username and password..... No matter how I try, I am unable to set up this existing Live mail account so that I can access it in Thunderbird...... along with my other email accounts in Thunderbird, which are working OK.... Any suggestions as to how to fix this annoying problem, would be really appreciated......... Thank you

This morning I realised I did not have a Unified Sent folder. There was a Sent folder in my list of folders in the Unified Folders section but there were no child folders and it was empty when I clicked on it. The Unified Folders for Inbox and Deleted were fine and I could click the arrow and select individual email accounts, it was only the Sent folder which was affected.

I tried numerous things, including clicking on each email account's Sent folder and clicking on 'Repair' and I think this iis what fixed it and now I have child folders in Sent and that seems to be working correctly... BUT now my Unified Inbox has disappeared!!! There is a folder called Inbox in the Unified Folders list but it is empty. If I right-click on it, there is no option to 'choose' any folders. I've tried clicking on each inbox and clicking repair (as this seemed to fix the sent folder issue), but it had no effect. I've renamed my virtualFolder.DAT to virtualFolder.old and I can see a new virtualFolder has been created, nothing has worked. Can anyone please help??

I use apple mail on my phone and Thunderbird on my PC and my (IMAP) email provider is GMX. I recently added a couple of sub-folders to an existing folder and changed the names of couple of others (in the same main folder). I did those changes on my phone. However, those changes are not reflected on my PC. The folders with changed names are in the folder list but greyed out but the new folders are missing. If I click on a greyed out folder it is empty. I've tried several ways to force the list to update but, so far have been unsuccessful.

What is causing my problem and how can I fix it?

Thanks for any advice.

I'm reading the question Thread's broken sorting makes it completely unusable and I have to agree that order of messages within thread is not the best one - ascending. For example, I am subscribed to a forum messages and I'm getting all the notifications for a topic to a thread. Currently I have like 85 messages in a thread and to see the newest one I have to scroll all the way down each time - scrolling 85 messages is a lot and it is getting worse because the number of messages keeps growing. After I've seen the newest message, I have to scroll all the way up to close the thread. (or am I missing something - perhaps some shortcuts?)

But I guess for some such ordering is obviously fine. Hence, I guess, an option how to sort threads might come handy. Perhaps even having a default sort order and an override per thread?

PS. funnily enough, I'll have the same issue with notifications for this question :)

the default font for writing texts is too small for me to easily read. Yet when I send the message the text size too large, How do I control these font sizes independently

I had Thunderbird on my Windows 10 computer. I bought a new Windows 11 computer and downloaded Thunderbird. When I try to set up my email account, I provide my full name (not my Thunderbird user name) and email address. The next screen has the message "Configuration found in Mozilla ISPDB ". I clicked on IMAP and hit continue. The next screen I type in my password for my Spectrum mail account. I have confirmed that the password works went I log onto the Spectrum website. The next screen has the Authentication error "Unable to log in at server. Probably wrong configuration, username or password.". I've also tried using my Thunderbird user name and Password instead of my full name and Spectrum password with the same results. I know my Thunderbird user name is correct but I can't be 100% sure that my Thunderbird password is correct.

I'm not sure if this matters but my email has the has the extension ----@socal.rr.com. This was assigned to me by my original email provider, which was Time Warner Cable. Spectrum bought Time Warner Cable a few years ago and I think Spectrum uses a different extension.

Years ago I used Thunderbird and for some reason stopped. I have a vague memory that there was a problem either with T-Bird itself or my installation of it. Can I see a demonstration before I elect to install Thunderbird now?

Hello, I have the latest version of Thunderbird. I have a problem for 2 weeks and every day I'm working to solve this problem. I have 17 accounts and Thunderbird shows me only 15 accounts. It hides 2 yahoo accounts. If I add other not yahoo account, there are no problems, I can add them. But if I add a yaoo account, Thunderbird doesn't show it/them on Unified folders. I see them only on All folders. Thanks for your help.

I was working busily in Thunderbird email, where I have a number of subfolders under "All Mail" where I store replies and such. One of the most important subfolders (which itself has many subfolders) has suddenly disappeared. I've looked manually through other subfolders, to see if I somehow moved it by accident, to no avail. Is there a way to search for a subfolder, or can anyone suggest where it might have gone?

Good morning,

this morning, after logging into my Thunderbird account, all my subfolders from my main account were in the "Trash" folder, and there was no correspondence in them. Folders named "V 2" also appeared in the Trash folder. Could you please advise if it's possible to restore these correspondence and folders to their previous state? I also tried using the "repair folder" function, but it didn't work.

Best regards and have a nice day.

Hello. Something strange happens in my emails. I read and/or delete an email and then at the bottom of any saved emails, the following shows up: no "from", no "subject" and no "recipient. It only shows 12/31/1969 5:00 pm. It is almost impossible to delete it. If I am lucky, it might finally disappear after closing Thunderbird and starting it again, several times. Becoming very much a nuisance. Thank you.

I went out of the USA on May to Ecuador and Peru, and on the same day the Android version of Thunderbird stopped retrieving new email from the server. I have used Thunderbird pointed to the same server on Windows 11 and Android successfully for years. I thought it might be something to do with being out of the country, but now I'm back in the USA, and sync account on Android still does not retrieve new mail that has accumulated since May 4th. I've been following my email using a webmail access so I know there's lots of new mail. I've closed and reopened Thunderbird on the Android, and I've tried sync account with the webmail access closed. I have not yet tried Thunderbird on my windows 11 laptop because I'm still not home yet. Any suggestions welcomed, thank you for your help!

I was cleaning up my Inbox when I looked at the "Important" folder. I read in a number of places that this is a "Gmail" thing, and messages get in this folder apart from any action etc on my part.

I have a couple questions.

FIRST, are the emails in the "Important" folder only in that folder or are copies in there? I deleted a number of 2 to 3 year old emails that I do not consider important today. The closer I get to this year [2025], the more careful I get.

SECOND, how can the auto-population of that folder be stopped and the folder be deleted? I keep my important emails in designated folders so I can find them.

Thanks in advance

I keep my mail (both sent and received) in local mail folders. My server is gmail, and sent mail is put in gmail's sent folder by default. Every few months, I copy those messages to a local folder, and after I back them up, I delete the server copy.

What to my dismay, I discovered today that only the message headers, and not the messages were present in the local folder, though they had been when downloaded. Looking at the file sizes, I found the sent file to be 0 Kb, and sent.msf 255 Kb, when sent should have been around 60 Kb long.

I have been able to restore the messages from backup (whew!), but I have no idea how then sent file was wiped out. I know I did not do it.

Has anyone else had this happen? Is there a preventive measure I should take?

After I migrated everything to a different computer, 'Local folders' no longer appears in the side bar, so I cannot archive messages locally.

Can some kind person please help me to reinstate it?
