The Android Thunderbird app has recently started bunching emails together in the inbox. I'm not talking about displaying a threaded view. What I'm getting is that when I select an email to view, Thunderbird opens up a small group of emails from the same sender. It doesn't seem to have any rhyme or reason to it either... emails displayed might be from the same day or different days. It's extremely irritating! It means that in order to view an email, I have to poke it once, and then again... assuming that the one I want to read is at the top of the displayed list. Why has TB started doing this, and how do I stop it? Thanks in advance, Ian

I recently installed Thunderbird for use with Gmail. I have created several message filters, but they keep disappearing. I have found that multiple filter files have been created:

Directory of C:\Users\shrdl\AppData\Roaming\Thunderbird\Profiles\ae352sn6.default-esr\ImapMail\imap.gmail.com 2025-10-28 22:30 385 msgFilterRules.dat

              1 File(s)            385 bytes

Directory of C:\Users\shrdl\AppData\Roaming\Thunderbird\Profiles\ae352sn6.default-esr\Mail\Local Folders 2025-10-28 19:07 241 msgFilterRules.dat

              1 File(s)            241 bytes

Directory of C:\Users\shrdl\AppData\Roaming\Thunderbird\Profiles\ae352sn6.default-esr\Mail\pop.gmail.com 2025-10-26 11:03 0 msgFilterRules.dat

              1 File(s)              0 bytes

Any idea why this is happening? Thanks

Running : Win 10 Vs: 145 I have many archive annual folders for a number of email accounts. I tried to archive messages today and nothing happens. Should a new annual folder be created for the group of messages I select, or do I have to manually create the folder?

My archive location is setup in the account settings and I've used it many times in the past. What am I missing?

Hi everyone,

I'm trying to add my school email address to Thunderbird, but I keep getting a "Unable to log in at server. Probably wrong configuration, username, or password." error. I know that the username is right, and for the password, I've tried using the right password vs. leaving that field blank. For the configuration, I don't know if that's right.

The auto-configuration finds a configuration in the Mozilla ISP database, but that configuration leads me to the aforementioned error message. If the configuration is wrong, how would I go about finding the right information?

Alternatively, might it be the case that my school (the organization) has disabled using Thunderbird for our email. For any help looking into this, it's a @berkeley.edu address.

Thank you for your help!

There were problems on the email server. As an emergency solution, a new access was created by the service provider for this email address. However, this does not contain the old emails. Unfortunately, I have already synchronized and no longer see all the old emails. However, I have now seen in the search function that I can still see the old emails in Thunderbird, but I cannot open them. You can see in the attachment that i can see emails when searching. But if i want to see one of the items ther ist the information "Keine Nachricht gefunden". How can I access these emails?

Please consider a slight change in the new feature where on the bottom right we have an opportunity to click on "as read" or "delete". Great time saver, but for heaven's sake you bring up the Thunderbird anyway. Come on ! ! ! ? The short cut is so we don't have to bring it up. What good is this new feature if it is exactly the same number of clicks as if you didn't have this new feature. Walt

I have several e-mail accounts on my own domain, via GoDaddy. They suddenly switched their e-mail server to Exchange, which forced me to switch from Thunderbird to Outlook. Can I switch back, yet, or can Tbird only handle one Exchange account?

I am temporarily using Win 10 (with security updates) but will regain access soon to a PC that can run Win 11.

Dear all,

It happened to me twice that the e-mais in the Inbox disappeared. Yet the Inbox showed that I still had 4 unread e-mails.

I installed the latest Mozilla Firefoxx update and now many saved e-mails in folders disappeared. All foders in alphabetical order after F cannot be founc no matter how much I scroll down. What can I do? Help!

Thank you very much for your help.

New laptop Win11.

Thunderbird installed and running, two differing ISP EMail addresses working.

Third address of four (fourth not yet tried) will not set, claims wrong user name/password.

This Email address (Sky as in Yahoo!) works perfectly on two other laptops under Outlook, it also works perfectly online from browser. So username/password is correct beyond doubt.

Possible complication (?) being while a Sky account address, login user name is an EMail for a different ISP's address. Did not have to do anything diff to basic login elsewhere though.

Ideas please?
