Thunderbird Community Forum

I have used Thunderbird for years. Suddenly it asks for my email account password every time I send an email message. What is the problem? The passwords for my email accounts have always been stored in my configuration and it never asked for them. Very annoying.

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.

"connection to server pop.mail.yahoo.com timed out" I have been getting this message in the activity manager for about a week now. When I click get messages, it says down loading message 1 of 1, but nothing happens.

Very little to do with accounts, but none of the selectable topics cover 'user Interface'.

Used to be able to open different accounts in different windows. Can't remember how, but it was obvious. Once new window is created, each time Thunderbird is started it re-creates them. I accidentally closed one and can find no way to re-open it. I use three email accounts each needing a different mindset, so keeping them in different windows helps. Also one has a screendepth full of folders and so is easier to handle in its own window. (The others are still there but only take up one line each when collapsed.

140.7.1esr (64-bit) Mozilla Thunderbird Snap for Ubuntu ubuntu-snap-build - 1.0

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.

Thunderbird updated to 148.0 today and I'm no longer getting mail from my AOL accounts (iMap). I get a screen that appears to be a signin for Oauth2 but when I enter my account info I get an AOL screen that indicates I should login with a browser already used. When I do that I login fine but still can't access the account with Thunderbird.

I use Thunderbird when Postbox acquired another. I am using 2 computers - desktop, old (10+ years), still Windows 10, and 2 two emails; new laptop (traveling), Windows 11. I download Thunderbird and set up my accounts - gmail.com and twc.com. Troubles with gmail.com, but finally I set up. However, I can't set up twc.com. I like twc.com-- no reason. (Time Warner Cable (twc) bought Spectrum. ) I can login twc.com webmail. Not Thunderbird. I looked carefully set up, Thunderbird searched, found "Host: mobile.charter.net" (Huh?, , continue, enter my password - "Error: ---". I removed VPN Windows 11, no difference. (Curios, my laptop and Firefox, my bank rejected connection. My desktop and Firefox still connects! I dread the day must update.)

I am look forward yours reply. (Maybe Spectrum is searching to dump twc.com.) Jeremy Fields P.S. I wrote with my desktop - windows 10 -, my new laptop (windows 11) is problems

Receive popup message: The certificate for mobile.charter.net does not come from a trusted source. In trying to send email, popup message: Sending the email failed. Peer's Certificate issuer is not recognized. The configuration related to mobile.charter.net must be corrected. Then it wants me to Add Security, Get Certificate.

Thunderbird is very glitchy and slow after the latest update - Thunderbird 140.11.1esr (20260522210329)

Especially, when I get a new email, Thunderbird stops responding for 5-10 seconds and then starts working.

I am using Windows 11

Hello, I use Thunderbird to manage several email accounts, one on them is not active anymore but I still want to be able to access the emails stored in my thunderbird directory tree, so I keep it active. And the fact is that every day this account tries to access a remote server that does not exists anymore to retrieve email that can not be retrieve, and every day I am asked for a password that cannot work. But the fact is that I did deactivate all options to read remote emails for this account, so that behavior is odd and I am not able to find a way around it. Any idea what to do not to be bother anymore ?

Thanks in advance for your help :-)

Put up a message regarding support to resolve issue with Thunderbird this morning. Cannot see the message or if any answers? Query was ref downloading email & history to Thunderbird while moving to another server provider (Gandi) and all history now missing.

I recently upgraded to version 115.10.1 and it is driving me utterly insane. It repeatedly turns on threading. I turn it off for a folder, next time I log in it's on again. I turn it off in a folder and copy that setting to all other folders, but it turns itself on again. Others say turn it off in Settings/Appearance. But I don't seem to have Settings/Appearance.

How do I stop this? Or is there a way to find out what version I was originally running and go back to that. I hadn't upgraded for a good while but my old version was much better. This one is also really slow and I hate the tiny text.

This is a new thing. The 2 devices (laptop and Kindle) have always synced my Outlook emails. New today. Can be fixed I'm sure but don't know where to start. Thanks!

Google sent notice that my password had been compromised, so I changed it. When I went back to Thunderbird to open email I got a popup to change my password, when I clicked NEXT I got a Message that said, "The server cannot process the request because it is malformed. It should not be retried. That’s all we know." Then I got an email through the Gmail website providing me an authorization code, but I have no idea where to enter that code. I've been working on this issue for a few days now and am in a Catch-22 situation with no idea how to proceed. Below are screenshots of the responses I've gotten so far. Suggestions???

On upgrade to 152.0, a pop-up asked for options I have not seen before. I cannot find info about what the net.thunderbird option is, nor why I would or would not want to click it? Any help out there?

Thanks!

How do I add the thunderbird email app into my firefox links area? I can load gmail into it but I can not find the www stream to use to get to thunderbird.

Thanks.

I was forced to change email from Comcast to Yahoo Mail and hate it. Downloaded Thunderbird and connected my gmail address, but it won't accept my Comcast address, which I use on Yahoo Mail.
