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!

Why do I get large blocks of scrambled text in my emails?

Here we go again! After spending a couple of weeks trouble shooting this issue, I thought I had it fixed earlier today.

After using TB for a couple of hours, getting rid of duplicate messages, etc., I shut it down. But when I decided to check emails one more time, the ORIGINAL problem is back, it will NOT delete messages.

I deleted all earlier installs, and did a complete clean install of 140.5.0esr.

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?

For the third time now I have found messages I have saved in Local folders in TRASH. I did not put them there, and the original ones in Local Folders are empty. I have had to manually move messages intended to be saved from Trash into my intended folders. I am perplexed why this is happening, as I have not chosen Compact Folders or anything. Very, very annoying. If it continues I will search for another mail tool

I redirect incoming messages into local folders for much of my incoming email. One of my primary sub folders has disappeared. I don't remember doing anything with it – at least not intentionally. It does not show in either the local or primary trash folders. It is not in the archive folder. It is not showing as a sub folder under any other local sub folder. Where did it go and how can I find it?

My wife’s Thunderbird has had problems for several weeks. To repair them, I have disconnected from our e-mail provider (Proton.me), & reconnected to it. Everything seems to be fine but her Thunderbird Inbox. There are no emails in it, but it insists there are two (2). I have tried to compact the folder & to repair the folder, but these actions have no effect. How do I get her inbox clear of this problem, so I can focus on her bigger problem?
