In Thunderbird on my Mac there appears to be no way of restoring alphabetical order to Folders.

All of my folders under A(and there are a lot of them) have dropped down a few alphabetical letters. There is supposed to be a right click on account name and restore this order, however, like many features on Thunderbird it does not exist now.

So a) why has Thunderbird on my Mac done this and how do I sort it out please?

Comcast has sent our accounts to yahoo. Email name remains the same. I wish to continue with Thunderbird. I haven't been able to and don't want to lose all my Thunderbird settings and files. They have been transferred to yahoo mail.

Cloutier728@gmail.com i need to add to my email cloutier728@email.com

The last new email I've received on Thunderbird for one of my accounts was on 5/13/2026 at 12:02 p.m. Every time I open thunderbird it tries to re-download the entire yahoomail account and times out. I have deleted all emails from the yahoo mail box from 5/13 and backwards. All spam emails have been deleted and the trash can has been emptied. Per online instructions I have also deleted the popstate.dat file, tried to repair the inbox file by right clicking on it, going to properties and clicking repair folder. I also tried to compact the folders, and have turned off my virus protection and nothing seems to be working. I also tried a new app generated password from yahoo. Current setup is pop.mail.yahoo.com port 995 SSL/TLS, authentication method = normal password. Any help would be greatly appreciated. Thank you!

Thunderbird has started acting as if it is the first time being opened after entering in all account info. All the folders expand down the left side (as if it's just finding them for the first time) and all email is re-downloaded.

Thunderbird is up-to-date using 151.0.1 on Microsoft Windows 11.

I have setup the same accounts in Microsoft Outlook, the issue is not happening in Outlook.

The email server is Ubuntu Linux, Postfix, Dovecot.

Suddenly Thunderbird takes a long time to download even a few (10-20) emails from Gmail and then it freezes on an email and as I click on different emails only the original one shows on the bottom half of the screen, even if I change to a different folder/email account. Also it will not close when I hit the X in the upper right corner.

If I click on one of the other apps, such as Calendar it goes to calendar but when I go back to email it still shows that same frozen email.

I tried clicking on the three bars (hamburger) to find the Thunderbird version and nothing happens.

I have restarted the computer but that has not helped.

This is an add on to the previous portion that I wrote yesterday. Today nothing shows in the portion where I usually view the message after I've clicked on it. Also the options in the tool bar such as File, Edit, View etc. do not respond to a click after the first time I have attempted to look at a message.

I am considering uninstalling and reinstalling. If I do that will it find all my emails and folders etc. again? There are a few emails that I am quite desperate to access that I have put in folders.

I'd really appreciate any help I can get on this as some important work is being delayed until I can access those emails.

Thanks for any assistance!

I was looking around my emails and when I thought I was trashing my junk emails in the trash bin it was my emails (that I keep).. I hit trash and they were gone, tried the undo and is there any way to get them back, would like to find out. I am a newbie to this kind of thing, so please be gentle when telling me what to do, also closed thunderbird and opened it up again, just wondering if someone out there can help me. Thank you for your time in reading this.

I have successfully set up 3 email accounts using my default domain. When I try to use an email account that uses a second domain I can't send or receive emails. This account required manual setup which I did but it does not work. My web hosting is with Namecheap and I do believe settings at that end are correct. Any help would be appreciated.

Hello, Previously, I had my email with Xfinity, but they stopped this service and set us to Yahoo Mail. I’ve had no luck in setting it up in Outlook, so I tried Thunderbird and encountered the same problem. I have Windows 11. I’m using the IMAP settings recommended by Yahoo. During the setup process, everything checks, but when it asks for an address, which is from Xfinity, and a password, which I’m not sure they’re asking for so I tried the Xfinity, Yahoo, and Mozilla passwords. I get the authentication error on each attempt. Help! Thanks, Parris

Thunderbird 148+ on Windows 11 repeatedly prompts for the password when synchronizing an Exchange account (professional) configured with the native Exchange support (no add-on installed).

The account only offers “NTLM” or “Normal password” authentication methods. OAuth2 is not available in the account settings.

During synchronization, Thunderbird asks for the password separately for many folders. However, clicking “Retry” usually works immediately without changing the password, and manually re-entering the same password also works.

The issue then reappears for the next folder, causing continuous authentication prompts (I have many folders...).

Actions already tested:

• deleting saved passwords and tokens,
• deleting/renaming key4.db and logins.json,
• restarting Thunderbird,
• recreating the account.

The problem persists.

This looks like an authentication/session handling issue rather than an actual invalid password.

I get your begging for money, you are obviously young, I have donated more money to you already than all my other email providers combined, period, you will allow me to move , remove as much as I want or I can delete you and you lose any future donations, but ticking me off with this we think this is junk crap trying to get more money from me only makes me want to DELETE YOU YOUNG PEOPLE, you act just like your buddy Google, lmk Anthony, or stop the bs

My trash folder deletes my emails after just 30 days. I want to keep my deleted emails in the trash folder for ever (or almost), but I can't a way to change the period for keeping the emails.

Thunderbird forces me to use the new amount hub. And I get authentication error when trying to setup outlook.com email

Had my computer recently setup linux mint with Thunderbird for my email access. I used the automatic setup to transfer across from Microsoft Hotmail/outlook system.

now all my emails -time sheets pay advice plus plus important emails are now being delivered automatically to deleted file. Not the inbox

I had a file callede archive where I would store all my previous timesheets pay advice these apart from previous month have been deleted - suspect its a automatic clean up after ex many days so thats lost permanently

How can I resolve this issue of the inbox going to deleted file/folder ?

So I have a list of folders some of which are the default folders some are custom created.

When I try to re-order these it is very hit or miss: I select a folder, drag it to where I want it to go, wait for the blue placement line to appear and it may or may not re-locate. Or I simply can't move the folder I want to move and so I move folders around it in order to achieve the layout I want.

It is as if success depends on whether Thunderbird is in the mood for a particular move to happen and I find it really frustrating. It should or shouldn't work, it shouldn't be that it works sometimes.

What is going on with this?

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,

A folder (Local Folder) shows that I have 20 UNREAD messages. I don't care about them and want to mark them all as READ right away, so I right-click on the folder and select “Mark all folders as read,” but NOTHING happens! I search for the “unread” ones, it finds them, I select them all and right-click, but no options are available! What’s the point of the search and multiple selection in this case?

Please either tell me how to do this in a single step or fix these usability bugs.

Best regards
