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

We have been using Thunderbird with a Cox email account. Cox has just transferred all its customers to Yahoo. I want to use Thunderbird with Yahoo. How do I set that up?

I've provided all of the other data, no problem. But the <Your login> field has only "YOURDOMAIN\yourusername" in it as a format hint. The field carries an Info symbol, but it's greyed out.

There are many possible domains, e.g. microsoft.com, office365.com, outlook.com, each with possible 3LDs, and the domain-name of the organisation that provides my account.

The most obvious (MYORGDOMAIN\Roger.Clarke) gets the error-message: > Authentication failed. Please check the username and password. (I checked, and they're the same as I use for a webmail login there).

Leaving it empty gets this error-message: > Unable to log in at server. Probably wrong configuration, username or password. (That about covers the possibilities then ...).

All of a sudden all of my Comcast accounts are receiving the message: "Alert from account XXXXXX: Temporarily blacklisted IP Address - Try again later". Contacted Comcast and elevated all the way up to the top technical group and was told it was a Thunderbird issue. Tried resetting passwords, etc to no avail.

Hi, I installed the latest Thunderbird on OS X Monterey for a friend and am using an Imap email account. Sending and receiving emails is working correctly. The problem is viewing what is in the inbox, it shows a certain number in the inbox but not all of those messages are showing up, some are missing. I've played around with the settings but I didn't see anythng that could help me out. On my own computer this works correctly, when I see a number in the inbox, it does show all of those email messages. Not sure what is going on, maybe it's simple like a setting not done correctly, or I missed something. Anyway, any help would be appreciated.

Thanks

Thunderbird updated to 115.10.1 (32-bit) and I cannot see any emails now. I use View > Folders > All. If I run a search, TB lists the emails. Have tried opening in Troubleshoot mode but still same, no emails nor inboxes. Windows Security Ransomware turned off for preparing for maintenance prior to TB updating itself. How should I go about fixing issue?

Windows 11, 64 bit Addons: Cardbook, Provider for Google Calendar

When I try to set up my inbox for my email within Remote Desktop, Thunderbird does find the correct settings, starts to log in and stops with a warning "User canceled primary password entry" and then hangs while Sending login information...

Below that warning, it says Password OK but nothing happens beyond there. Unless I stop it, it stays at the Sending login information... stage for 5-10 minutes before timing out.

What is causing this cancelling of primary password entry? (as in nothing I'm doing).

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

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

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.

I may be missing something, but how can I remove threading completely from Thunderbird or how can I download an older version. I"ve searched for 102.15, but cannot find a way to download it. I really prefer NOT to use another email client. I've always used Thunderbird, but I cannot tolerate this threading thing and I can't seem to disable it.

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

Every year I am required to update my university's net id password. Normally T'bird responds asking for a password update. Not this year; I am just cut off.

I followed all instructions from the T-help site. But it is impossible to update the "saved password." "edit" is not allowed.

When T-bird did ask me to connect via Google, see the screen shot, the next screen locks with a 403 error message, also attached.

I would like to continue to use Tbird, but this is making it impossible. My university's IT people had me download the T-bird again, but the problem persists.

Please advise soon.

I have had very few notices about Thunderbird upgrades. My records show Setup numbers: 3.0.exe, 8.0.exe, 52.4.0.exe, 52.9.1.exe, 78.12.0.exe, and then 115.5.2.exe. My address book made it through all but the last upgrade. No notice that I should save a copy of my address book ever showed up in any correspondence. I tried reinstalling an old upgrade but the upgrade always wants to update the installation. I did try to reinstall 52.9.1, but the next screen wanted my name and password. It would not accept any name and password that I could remember. So I tried searching for them at Xfinity and Comcast to no result. I did not try my Firefox password because it didn't seem appropriate. Incidentally, my records show 135 upgrades for Firefox for the same length of time as the upgrades for Thunderbird. My fear is that my address book is unrecoverable. I chose Thunderbird because I ofigured none of it would need backup if it became necessary to reinstall Windows 10. Which happened last year. I did not expect Mozilla to change Thunderbird so drastically that I couldn't get every thing back. Sorry but I'm a senior citizen and not computer literate. If I have to try to recreate my address book I may as well use Microsoft's Outlook as it looks somewhat simpler than Thunderbird - which I doubt.

There is an email account profile on my Thunderbird email program and I simply cannot get rid of it. I have tried everything including running the program as an administrator and nothing works. None of the instructions to remove an email account anywhere on this forum works. When I go into the account settings, there absolutely no selection for me to remove a particular email account/profile from Thunderbird. I have removed Thunderbird, wiped out all traces and profiles for Thunderbird, reinstalled Thunderbird and this particular account keeps coming back. I bought a new computer, installed Thunderbird on that, and this particular email account suddenly appears on the new installation on a new computer. I can't get rid of it. I brought both computers to a technician and they scanned for viruses, trojans, etc., etc., etc., and there is nothing there, but this email address account keeps coming back on any computer I have installed Thunderbird, including new computers that are new out of the box. The email account I want to remove is clogged with spam and tying up my internet connection and the ISP (Charter Communications) will not help me by eliminating this particular email account. I have followed multiple instructions I have found on this forum about how to remove an unwanted email account from Thunderbird and not a single one works because the selection to do this does not exist in Thunderbird. All I get is asked for a password for the email address that the ISP says doesn't exist, but it is being flooded with hundreds of thousands of emails that get sent to this email address in my Thunderbird program. Every time I run Thunderbird, it locks into this particular account and downloads emails until my hard drive is full and crashes. Is there a way to get rid of this email account on Thunderbird or do I just remove the whole program from my computer and use something else?

I've had long conversations with Apple regarding the setup of iCloud email accounts on Thunderbird. The process must include the generation of an App Specific Password using Apples web page :

https://appleid.apple.com/account/manage

This generates a password in the form aaaa-bbbb-cccc-dddd which is a different password to be used only with one Windows APP. Apple insists this is working with their standard mail server settings preset by all the email client providers. I've been advised to refer to Mozilla Thunderbird and Apple are insistent they can do no more than mail me links to all the instructions I've already read in detail several times. However, I believe the problem lies with Apple but they don't yet know it. I've used separate ASP generated passwords and tried to install an iCloud email on several different email clients: Thunderbird, Mailbird, Outlook and Postbox. All these confirm that the settings seem to be valid but nonetheless the email account fails to load with error messages suggesting the configuration or password (i.e. the ASP) is wrong. The common factor is Apple not Thunderbird. I suggest anyone flummoxed by this awaits the acceptance of this problem by Apple.

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
