Thunderbird Support Forum

I remember when you could select a range of messages and delete the lot quickly. This is how I maintain my email. For a while now, and still, it takes a bit to sort messages, normally for me sort is by "Correspondent". Then when I select a range and hit delete, I may as well go do something else. Thunderbird goes unresponsive for the long duration. It is a major problem.

I am still using Win10 Pro, system disk is an SSD (1 TB) and the data disk is a normal HD (4 TB). 16 GB RAM, a Lenovo tower. It is not running out of memory, the drive isn't over utilized either. A 15 message delete is slow, try over 100 messages!

All other programs run fine, it is used in electronics design mostly. This issue popped up a while ago and I kept hoping it would be fixed. It hasn't yet. The OS is kept up to date, no other changes. I do compact folders regularly, so indexes should be optimized.

Hi.,

 Cox cable just discontinued their email server and moved all it's email accounts to Yahoo.

I had been using Thunderbird successfully with Cox for several months before this happened.

 I am able to send and receive emails now via my new online Yahoo server;  however I have not

been able to connect / use Thunderbird to send and receive emails since the Yahoo changeover. I have tried many things, but I either get a "failed" error message or a "timed out" error message. Yahoo support has not been able to figure this one out. They are hard to get a hold of and hard to understand (communicate with). They are overseas from the US.

 I appreciate any help you can offer.

Kind regards, Ken

It all started about 3 days ago. I was having problems accessing my att.net email account on both my iMac running Thunderbird 115.10.1 and on my iPhone running iOS 17.4.1. I changed login password and was able to get the mail on iPhone, but not on the computer running Thunderbird. I got the settings information for both POP3 and IMAP from att. I first tried to go into Thunderbird and was able to find the email protocol settings and they were correct for POP3, but still not retrieve email. The error message I last received is, "Sending of password for user ******@att.net did not succeed. Mail Server inbound.att.net responded:[SYS/TEMP] Server error - Please try again later.

My email is on a gmail server. I've been using POP for a long time. My inbox in gmail has 160,000 emails. They go back to 2005. In Thunderbird I have moved emails from inbox to to various local folders. Right now I only have from 1/1/2022 forward in the Thunderbird inbox.

Let me know of any way of migrating to IMAP

Thanks in advance to any replies

For some reason, my Thunderbird recently "updated" to version 115.10.2, and the "About Thunderbird" dialog says that it is on the "esr update channel." I can find no information about the esr channel. However, when I start Thunderbird, it displays the "Welcome to Thunderbird DAILY" screen. Am I correct that this is an error? If I were really on the daily channel, I think that the version number should be higher.

Hello,

i'm currently trying to set the font 'Aptos' in thunderbird 115.9.0 to the default font for writing e-mails.

I do know that there is an option to configure this under 'settings -> writing -> html-options -> font' but when i try to change this i seem unable to find the font Aptos in this list. I do however have other programs installed on my computer, that already use this font. How can i get and set this specific font in thunderbird?

Kind regards RedPanda

I recently had to re-install Windows. I saved my Thunderbird profile. I re-installed Thunderbird and when imported my profile, I could retrieve my messages but could not send messages. I attempted to change the settings and wound up creating two additional Pop3 accounts. Now I can't send or retrieve messages. My provider is Charter/Spectrum. I have tried all the settings they suggested. How do I get out of this fix? Thanks.

I have several users who are migrating email from Outlook, and they want me to confirm if the Thunderbird export will bring over:

• drafts
• sent mail
• deleted mail
• any subfolders in the mailbox

Thank you!!

Thunderbird Error Message (attached). Sending of the message failed. The message could not be sent because connecting to the Outgoing server (SMTP) cs15.uhcloud.com failed. The server may be unavailable or is refusing SMTP connections. Please verify that your Outgoing server (SMTP) settings are correct and try again.

What is the phone number for support?

I have a folder set aside for a non-profit I volunteer for. I want to backup all those emails separately so that they are 'easy to access' - it's a regulation. How??

Hello, I got a tale of two computers with Thunderbird on both. First, I will start with my HP Laptop, its my primary computer due to its speed. I went to check my emails this morning. I double click on the TBird icon on my desktop. It does not open. Waited a few seconds, tried again and again. Finally, a folder containing pictures opened up. Then, I went to open FireFox, and that same folder with pictures opened. I tried this like five times and the same thing happened. Then I got to thinkin, when I went to shut it down the other day, it said "update and shut down", so I did. Now that I remembered the update, I decided to go back in time to when the laptop was running real good. So I did that recovery, in doing so, it wiped out some of the applications I had on my computer, such as FoxFire, Thunderbird, Adobe, HP printer, CCleaner, and probably others that I seldom used. Somehow, I got to the point where I reinstalled Thunderbird. The only thing is, it would not let me in. When double clicking on the icon, it took me to a page that just wanted my name, email address and password. I enter the info, that page stayed open and added a few more items to the page, such as IMAP and POP3 stuff. IMAP was already selected by Tbird. I then had the option to click "done" . In doing that, it said "Unable to log into server. Probably wrong configuration, username or password" So there's that. Cannot even see the email program. Second part of the mystery, I have an old Gateway desktop. Its slower than slow. I only use it in emergencies, as the above scenario. I fire it up, wait about 5 minutes before I open Thunderbird on that. Guess what, it wants a password. Whats different about this deal is that the email opens, and I can see all my previous emails, but cannot receive or send. I have no Idea whats going on, unless its my deceased wife coming back to haunt me...I don't know.

Been using Outlook, but am having issues. Decided to try TBird. Got the email part set up (far as I can tell). Calendar and Address book are a different story. Calendar: Using Google Calendar as primary calendar. Consists of an appointment, birthday, and holiday calendars. Created a new calendar and entered the URL for my Google Calendar. It showed up in TBird apparently OK. Created ANOTHER calendar and entered URL for Googles stock Holiday calendar. It also seemed to show up OK. Tried to do what I did with those calendars to add my Birthday Calendar, but Google uses data from Google Contacts to create that calendar. Can't figure how to add that data. HELP? Address book: Exported Google Contacts Data to a CSV file. Tried BOTH Outlook CSV and Google CSV exports. NEITHER produced a CSV file ANYWHERE Close to what TBird appeared to want, based on what showed up on the "fields" page that appeared after I chose the CSV filename. Moving data around in a spreadsheet is a Royal pain. Isn't there a Google Contacts CSV export file that more closely approximates the arrangement that TBird WANTS?

Questions like this have already been asked, but I didn't find a proposed solution I'd like, and none of the threads are still open for comment. I guess this question should be considered as an enhancement request.

Our small association has about 600 contacts, which have to be divided into several mailing lists, for two reasons: 1) Service providers limit the number of contacts per mailing and per hour or day.

Perhaps, a future version of Thunderbird could have autiomation that sends long address or mailing lists as batches of 50 (for example), with a suitable time interval between batches. Presently, these repetitive mailings have to be done manually, which leads to errors, of which the worst is forgetting to put the addresses in the Bcc field (which can't be set as default).

2) Our members have various non-exclusive functions and activities, such as committee member or participant in different activities, so that a given contact might appear in more than one mailing list.

Manually constructing these mailing lists, for example by drag and drop, is tedious to say the least. So would it be possible to provide a means of selecting contacts for a given list as a function of contact data? For some purposes this could be simply the position in the alphabet of peoples' names. We would use in addition the 'custom properties' fields (which seem to be limited to 4 when manually editing a contact). While this approach is identical to the one we use routinely with spreadsheets, I'm aware that spreadsheets are or should be banned for managing lists of contact data.
