Cox.net is transitioning from in-house e-mail to e-mail handled by Yahoo.com. Our cox.net addresses are supposed to (and apparently have) transitioned so that they still work, but are processed through pop.mail.yahoo.com.

It is my turn to be transitioned and I have been successful in doing so to the extent that I can send and receive using my address(es) ...@cox.net through Yahoo web mail and on my Samsung phone. I have not, however, been successful in either sending or receiving mail using Thunderbird on my desktop.

I have been successfully using Thunderbird with POP settings for years with four different cox.net addresses. [I'm currently just trying to get two of them working -- unsuccessfully.]

I am using Windows 10 on a Dell desktop. I am using Thunderbird 115.9.0 (32 bit). I have reset the POP and SMTP settings as directed by Yahoo. One of the errors I receive is: "Error with Account .... Sending of password for ...@cox.net did not succeed. Mail server pop.mail.yahoo.com responded (SYS/TEMP) Server Error - Please try again later." It then asks me to retry or enter a new password. I have checked the passwords saved by Thunderbird and they are correct.

I suspect, that with all the Cox accounts being newly routed through Yahoo servers that I am not the only Thunderbird user experiencing this problem. Does anyone have any suggestions? Is it likely to help if I uninstall and reinstall Thunderbird? Would I loose all my mail, etc. if I did that? [I did the delete and add account in my phone and that was successful, but I wasn't concerned about losing mail there as it is all on my desktop.]

Thanks in advance. billb1111

With the moving of Cox emails to Yahoo would it be feasible for Thunderbird to put an instruction list(with screenshots) of how to get all our TB email accounts from Cox to TB? Do we have to delete all our TB email accounts and re-enter them into TB under the new Yahoo or can we just change the server settings on the existing Cox settings? If just changing server settings what are the settings for the new yahoo? All my accounts are IMAP so if instructions could be made, maybe one for IMAP and one for POP for those who use either. Thank you

I have two email accounts on Thunderbird. One, the gmail account still works perfectly, but the other, a cox.net, has started today to not move and messages to trash or junk as set by the settings. This problem is across all my devices, PC, ipad and Iphone.

I use Thunderbird for my email. I have two computers and have donated on each on of them over the last few weeks. The Donate page appears when I am in my email and takes up the bottom half of the display. How do I get rid of this and stop it from coming back? Thanks for your help. Gary

Running 115.5.0 and want to export my contact list to be able to use it in a spreadsheet. The export function in the Tools dropdown only allows for export of "accounts, messages, address books and settings to a ZIP file." What happened to the ability to export just the address book separately to a csv file? Please help. Thank you.

I am showing beside the inbox that I have 4 unread emails, but I have nothing in the message (inbox) folder. I have looked everywhere and cannot find these messages anywhere.

Is there a simple fix to enable links in emails? I've tried several suggested fixes but still the links don't work.

Changing settings documentation is confusing for non-developer types. Instructions are cumbersome and unclear.

How do i delete 155 emails from the same sender? Or 52 emails from the same sender? Or how do i delete multiple emails from the same sender, but they are not junk and i do not want to inhibit my receiving emails from the sender? Thank you

I have Thunderbird, version, 115.6 on my iMac. Up until this morning I have had no problems.

First when I used "Get Messages" this morning it kept telling me there was an error with my server. But after the error was fixed by contacting the server, Thunderbird was no longer able to connect to the server any more. I can send messages ok and they go through but I can't receive them since "Get Messages" no longer works.

My Apple Mail program on my laptop works fine, so the server is back to working properly and I can pick my Thunderbird sent messages there.

How can I get Thunderbird to connect to my server again for incoming messages?

Thank you, Martha

When I attempt to send an email, I get this pop-up:

Sending of the message failed. An error occurred while sending mail: Outgoing server (SMTP) error. The server responded: impout006.msg.chrl.nc.charter.net cmsmtp 15.181.97.27 blocked. Please see https://www.spectrum.net/support/internet/understanding-email-error-codes for more information. AUP#Out-1130.

My ISP is Spectrum, they said issue is with Thunderbird, incoming s/b 993, outgoing 587, which I confirmed. How can this be fixed?

I'm very confused. I've been using Thunderbird as my email server for a few years. Recently, I stopped receiving emails December 12, 2023. I sent in a problem according to the help page that I found. I believe Mozilla is now the server for Thunderbird? I don't even know if that is accurate (part of my confusion). I followed prompts and confirmed my email address, apparently I now have a user name. I still can't send or receive emails. Can you help. I need step-by-step instructions, please.

Hello, Experts:

First up, I'm a happy user of Thunderbird with some years of experience. I make use of filters, and up until about 2 weeks ago they all worked. Now two of my filters (not all) have stopped working automatically, and I have to go to Tools/Message Filters and run them manually.

I'm on TB 102.15.1.

I have deleted the non-working filters and re-created them. No change in behavior.

I would NOT like to de-install/re-install TB because it's a good deal of work, and TB is a critical system for me.

That said, I keep a laptop computer for travel, and the filters work on that platform. IS THERE A WAY to copy a file or folder over from the working laptop onto my desktop machine, where the filters have failed?

Thanks in advance, Bob

Still waiting for help with my annoying thunderbird problem. Once you help me solve it, my donations will begin. The browser link in my incoming email stopped working about 3 months ago. I have to right click on the link, start my browser manually and paste the link. I've tried it with Firefox, Edge and Chrome (preferred) and none of them work.

I want to single space my out going messages. I changed the paragraph setting from body text to paragraph format, this temporarily fixed it but it went back to double spacing

I recently (on the 28th Nov '23) updated TB to the latest version. It was so awful though that I uninstalled it and reinstalled version 60.9.1. However, now my address book is empty. I did have an old csv file which I was able to import, but it's quite old and missing a lot of addresses added more recently. Where did the saved email addresses go? Are they likely to still be out there somewhere? Thanks, Ian
