Thunderbird Community Forum

Dear community,

I'm planning to change my email provider and during the transition period I need to have the old and new accounts running concurrently. The help article states:

".....you can create additional profiles, each with their own set of account configurations, messages, etc. (Note, each profile can access multiple email accounts''.) .

but I can't see how this would work. If anyone can explain in simple terms how to achieve this, or point me to the relevant information I should be most grateful.

Hello all:

After migrating to a new machine I finally have TB set up and running nicely. As I checked the individual settings and C: folders for the e-mail accounts under the server settings for each account (there are two, law and business), and the local folders (for long term e-mail storage, under Local Folders, Local Directory settings), I discovered the C: folder for the Law e-mail account is gigantic - when I check the properties in File Explorer it comes back as 331 GIG, yes, gig. More disturbing is that most of this appears to be "dark matter" that does not "show up." I total the visible files and folders inside that location and it is roughly 150 meg.

For comparison, the folder directory for Business e-mail account is only 24.9 gig, and the directory for the local folder for long term e-mail storage only clocks in at 11.1 gig.

Any ideas why the law firm e-mail account C: drive storage would be this large, with so much of it not visible?

Thanks for any thoughts.

Dear Sir or Madam,

I have lost all stored folders with my email correspondence from the Local Folders for an unknown reason (I restarted my computer, and they disappeared). I can find some of these emails using the search option, but I cannot see the path of their storage location. I have checked my Profile/Mail/Local Folders, but they are not there. Are they stored on the server? How can I recover these folders?

Thank you very much in advance,

Jasmina

I recently bought a new HP laptop running Windows 11, and installed Thunderbird I am still using an older HP laptop running Windows 10, running Thunderbird for years without issues

I installed Thunderbird on the new Windows 11 laptop (without using the USB drive for the profile) and managed to carry over the address book using my account from the old laptop. It is working, but acts odd when deleting emails.

When I delete an email (by highlighting it and hit Delete) in the Inbox, it disappears from the Inbox, but it still shows up in the All Mail folder. When I try to delete it from the All Mail folder (by highlighting it and hit Delete), it disappears for a split second and then comes back. The only way to permanently delete ANY email is to move it to the Local Folders - Trash.

It's like playing whack a mole!

I'm wondering if there is some setting issue, or if I should just uninstall Thunderbird, reinstall it again using the USB for the profile from the old laptop and start all over.

I would appreciate any help!

I would like to set up an existing Gmail account in Thunderbird.

The following window appears: (see Image 1)

I click the next button, and the next window is: (see Image 2).

How can I sign in to Google? Perhaps in a different way?

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.

My mom needs help accessing her emails she had acs internet and had to cancel the service for 4 months and her email is X@ptalaska.net and she has the service again with acs and woukd like to have the back emails resent.

Please reach out to her through her email thank you for your help and time

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
