About once a year suddenly Thunderbird does not recognize my passwords for my two email accounts. I don't know why this keeps happening and how to get the passwords to work.

My email mail.com stopped working and ask for a new password. Putting in a new password does not work. It may be related to a T-mobil internet problem that they emailed me that it was fixed. My other emails are working OK. I get this message "Login to server imap.mail.com with username jmaugee@mail.com failed." My email to jmaugee@mail.com does not receive emails that I send from my other email address. John Augustine

I have trouble with the lack of clear outlines in Thunderbird.

In particular:

1. the lack of a line between the message header and the message body makes it harder to find the right spot to scroll messages

2. the lack of a line between the nav-sidebar and each section in settings means I *cannot* scroll settings without getting migraines from the @#$%% nav-sidebar. I have to tab several times and then page down.

I can't enable a high-contrast theme within Thunderbird. I can enable it at system level, but it breaks many other apps, and it breaks my cursor and highlight color settings, and I have to recreate those settings each time.

I can search for "contrast," or "outline," under themes, for example: https://addons.thunderbird.net/en-US/thunderbird/search/?q=outline&cat=themes&appver=148.0&platform=WINNT

I can't tell which themes are supposed to fix what; I tried 4 of the resulting themes, some added other outlines, but none added the needed outlines I listed above.

For no obvious reason, Thunderbird started complaining about my existing configuration to mail.com. I tried changing passwords, I tried rebooting the computer, but nothing would work. I kept getting the "invalid password" popup when trying to connect. I've double-checked that mail.com is still working (I can access all my email from the web client no problem).

So, eventually, I deleted the account from Thunderbird altogether and now I'm trying to recreate the configuration. Thunderbird recognizes mail.com and correctly deduces the server configuration settings, but it will not connect. When I try to add the account I get this message:

"Authentication failed. Either the entered credentials are incorrect or a separate username is required for logging in. This username is usually your Windows domain login with or without the domain"

Why on earth would a "Windows domain login" be needed for a web-based email location?? When I had the configuration set up before, all I had to supply was my email address and password.

Something in Thunderbird has changed and I can't figure this out.

Meanwhile, I have about 10 other email accounts set up on Thunderbird and they all seem to be working properly.

Would sure be nice to find a solution so I can get my mail.com account back on Thunderbird.

Thanks for any help you can provide.

I am using the Thunderbird software (140.7.1esr 64-bit) for mail merge purposes on a Windows 11 operating system. However, when I start the mail merge process, it begins initially but then automatically disconnects before completing the task.

Due to this issue, I am unable to complete the mail merge properly. Kindly look into this problem and provide a solution as soon as possible.

Thank you.

1. Some messages come to my mobile devices but not to my Mac. 2. I watch a message down load but it doesn't end up in my inbox or junk folder. 3. Junk folder says there are 14 messages in it, but when I open it, it's empty. 4. Yes, I'm up to date with Thunderbird. Also, the Mac is up to date. Problem began before latest updates. I have shut down the Mac. I have quit the Thunderbird application. No improvement. 5. I use Comcast for my ISP.

Rookie move. I deleted a calendar (not realizing that by deleting the calendar, which I didn't use, I was deleting all of my tasks).

Is there a way to restore the calendar?

I was using MS outlook and recently I could not connect. Apparently ATT made a change so that instead of a password you need a Secure email Key. Since I needed to make a change I thought I'd try Thunderbird mail, but I still need the KEY. After a number of efforts with the ATT AI and human support people I could not find where the Key is entered on ATT. Now I know this forum is about Thunderbird and not ATT, but there must be Thunderbird users that have ATT and have made a seccussful connection. There are a few ATT help pages that outline how to do this, but each time I look at my ATT profile I can not find where to enter the Secure Mail Key. Is there anyone that can help me with this? THanks Mike

I have never deleted so many emails at one time, around 500. Did I exceed the limits of Thunderbird? I cannot log on. Cannot see new emails. I have been on emailsrvr.com and did verify my passwords. Thank You

I received this message: Unable to connect

The connection was refused when attempting to contact localhost.

   The site could be temporarily unavailable or too busy. Try again in a few moments.
   If you are unable to load any pages, check your computer’s network connection.
   If your computer or network is protected by a firewall or proxy, make sure that Thunderbird is permitted to access the web.

I am not receiving new email. What do I need to do to get it working again?

My email is on a MS exchange server, and I have installed Thunderbird using Owl. My Thunderbird email is my main email. A couple of weeks ago, it stopped working, I then reinstalled Thunderbird, but I had trouble configuring it on the exchange server (instead of POP3 or IMAP). I can receive my email but I always get an error when trying to send email Can anyone help me? I'm desparate. My IT person wants me to switch to Outlook (which works).. I do not wish to switch. Please help.

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

This started last year and I found a fix on google but I can't remember it. It has noiw come back and is driving me nuts. About 2-5 minutes into composing an email thunderbird goes unresponsive and is greyed out. i have waited 30 mintues and nothing happens. It does not happen until after you type the first character into the new email. I have checked user rights on the thunderbird folder and my windows user folder and I have admnin rights on both If i shut Thunderbird the email appears in drafts when i restart, but only from a bit before it froze. I have reinstalled, compacted nothign is fixing it. Using 64 bit 140.3 on windows 11 home.Tried update to 140.3.1esr. no difference. Just about to give up and go to Outlook because I don't write trivial emails and this is a PITA

Thunderbird is what Outlook was striving to be. It looks like Outlook, but out performs every thing I have tried. and it Works!!!!!!!!!!!! Cudo's Love this product.............................................................
