Thunderbird Support Forum

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?

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

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

I have Thunderbird 115.9.0 64 bit on the 2nd latest version of Ubuntu Linux and by second latest I mean it is still supported even though there is a new version available. Several months ago there was a password problem with my internet account preventing me from logging into my internet/email service and all my devices could not send or recieve emails. I changed my password on my cell, my Windows 10 computers and they worked fine. My Thunderbird on my Ubuntu on the other hand rejected my password and I also checked all of my port and server settings with the help of my internet service provider tech support including comparing settings from other email clients. Still no password being accepted. My internet/email service provider tech agent suggested removing my account from my client and reentering it and this worked.

Several months later I changed my main email passwords again on incoming mail and outgoing mail servers on my account, verified my port settings are correct, which they were including the type of security and protocols used. When I select the desktop icon I get prompted to enter my main password and hit enter and the window keeps reoccurring as if it has rejected my password. I select cancel allowing me to enter and again clear and reenter password and again it is rejected. I removed my account (I think) and go through the motions of reinstalling my account and get a pop-up indicating the server already exists which puzzles me. Ports, security settings, password are all correct and tested on other devices. I can even use a browser and log onto my internet service providers server and access my account and my password works but not on my Thunderbird. Should I consider uninstalling and then reinstalling my Thunderbird on my Ubuntu? I think by mistake I deleted all of my emails BUT I have selected IMAP so my emails I want are still on my service providers server. IF I uninstall and reinstall how do I save my contact list. This I Inoticed is still intact. Suggestions please?

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.

This is a recent issue. If I send an email with no images and no attachments, it copies the email into my "sent" folder with no problem.

If I send an email with even a small attachment...it sends the email, but "times out" copying the message to the sent folder.

I've checked the account/server settings, they are exactly as recommended. I've changed the sent files to "other"...no difference. I deleted and reinstalled Thunderbird...no change.

Ideas?

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.

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.

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.

Hello,

This is my very first post to a support community so please excuse me for any rookie mistakes and oversights.

T.B. 115.8.0 (64-bit) Windows 10 - IMAP settings with multiple domains and multiple accounts on each.

Problem/Issue: Most searches return the expected results, but in certain cases, and seems to affect mostly the sub directories in Local Folder (have not been able to replicate problems in strings found elsewhere).

Things I have already done: - Rebooted PC - Compacted the folder where the email resides - Repaired such folder - Confirmed that Global search is clicked for such folder - Opened the email to confirm that it does open and is valid (Remember that it's in Local folders so already downloaded)

E.g. Global search string "Re: New Project 25-301-623 needed into Swahili - word count 321" (which does exists in Local Folders) does not produce any results but (Deleted first character of the string) "e: New Project 25-301-623 needed into Swahili - word count 321" produced results for "New Project 25-301-623 needed into Swahili - word count 321" without the results for "Re:...". Additionally, no filters are displayed such as Location, People, etc. (Running the same search within the folder where it resides works fine.) Cutting down the string to only "Re: New Project 25-301-623" still does not find any results. Global search for string "Payable Summary for: August 2022", which resides in the same folder tested is found but no filter data available for Location, People, etc. However a search for "Project delivery for Job: 25-258-813" again residing in the same folder is found with Location, Account and People. I've tested same approach and tests on different folders to rule out Folder specific problems and behavior is the same problem.

Another example that might help in figuring things out. I tested a string of an email subject from an amazon order, which are long in nature do to # dashes, long numbers, etc. Performed a global search and the email was found but no Filters shown. Did the same search removing the end of the string "has shipped" and the email was found once again but with all Filters showing.

I hope I have been thorough enough. If any additional information is needed please let me know.

Thanks to all.

""Description: COX Server Name: smtp.mail.yahoo.com Port: 465 Connection Security: SSL/TLS Authentication method: OAuth2 User Name: your user name, duh - Mine keeps changing the user name to the last name I put into any of my 6 accounts. The only way it will send mail is if the correct user name is in the correct account (obviously). Why is it changing constantly? click OK""

I've read the "fixes" from 2023 and they do not work for me. I tried changing the DESCRIPTION to blank, didn't work. Changed them to the corresponding e-mail for the account. Didn't work. Changed it to "SMTP" with the corresponding e-mail. Didn't work.

It keeps changing the last one I edit to the one I edited before it. It's driving me crazy. Won't send mail unless the User Name is correct (obv.)

Whole mess started when forced to switch from Cox to Yahoo recently. Seems to be working other than TB changing the name as soon as I type in the next one in the next email address and then it not working until I change the User Name back to the proper e-mail address of the 6 accounts.

Cox Communications recently discontinued its e-mail services but provided a simple, direct transfer path to Yahoo Mail. The transfer retained the '@cox.net' referent in the e-mail address -- e.g., 'myusername@cox.net' -- to make the transition to Yahoo Mail seamless for all correspondence. The new Yahoo Mail username also now includes the '@cox.net' referent -- e.g., the former 'myusername' under Cox is now 'myusername@cox.net' under Yahoo. The transfer was successful, and e-mail send & receive functions for all of my old Cox accounts now work on the Yahoo Mail servers -- but ONLY in Yahoo's webmail.

in order to get Thunderbird to recognize my existing accounts under the new Yahoo regime, I went to 'Set Up Another Account > Email' and entered the required information, as illustrated in the attached screenshots. (See attachments 01 & 02.) The Set Up procedure initially found the old Cox server settings, apparently from Mozilla's archived data for the account. I Then performed a manual configuration, and, as indicated in the attached screenshots, the Set Up procedure also successfully found the new Yahoo Mail servers. Success, right?

Wrong! When I restarted Thunderbird, the new Yahoo Mail server settings were in place, but the username had not been updated -- it lacked the '@cox.net' suffix. After manually amending the username and again restarting, the new server settings and amended username were in place, but connection to the Yahoo servers failed repeatedly. (See attachment 03.) A second round of the 'Set Up Another Account > Email' procedure revealed that the archival Mozilla data had not been updated -- it still pointed to the old cox.net settings -- and a second manual configuration led to the same results as the first: Thunderbird failed to connect to my account on the Yahoo Mail servers.

I then looked for a way to completely remove the existing account from Thunderbird, and then to create a new account from scratch for the existing account on Yahoo Mail. I consulted Thunderbird online support advice [ref. 'Close My Account - https://support.mozilla.org/en-US/questions/1395523 ]:

"If you created a mail account in Thunderbird for a particular email address to download emails from server then you can easily remove it ( Menu icon > Account Settings -- Select name of account in Left Pane -- Click on 'Account Actions' -- Select :'Remove Account'. -- Restart Thunderbird. ),"

However, I could find no 'Remove Account' selection anywhere in the version of Thunderbird that I am using (ver. 115.9.0 - 64-bit)!

Please explain what I must do:

   1. to make an existing Thunderbird account originally set up for an old '@cox.net' address hosted on Cox servers now connect to a new '@cox.net' address hosted on Yahoo Mail servers; 

or, alternatively,

   2. to remove all traces of an existing Thunderbird account originally set up for an old '@cox.net' address once hosted on Cox servers, and then to set up a new Thunderbird account for the same '@cox.net' address now hosted on Yahoo Mail servers.

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.

Hello. I was searching my Inbox for e-mails I knew I had, but they weren't showing up! After doing a general search, I found the e-mails in the search results. Then, I clicked "open in conversation" and they were all there and labeled with "Inbox" or "Sent" folder, respectively. So I right-clicked and selected, "open in containing folder", but it didn't work! The "containing folder" opened [i.e., the Inbox], but didn't show the e-mail! So then I searched manually by scrolling in the Inbox to the date of the "hidden" e-mail -- yet it wasn't there!

(In other words, when I did "open in conversation" from the search results, it showed the conversation, but I can't actually see the e-mails in their containing folder!) Besides for this problem, but I think there are a lot of other e-mails that are "hiding" in this way as well. What should I do?

Thanks for any help you can provide!

Sincerely, Jonathan Rosenberg

I have a personal family domain, with email service - my provider supplies me with a number of pop3/smtp addresses.

I have a Thunderbird a/c setup on a desktop running Linux Mint, thgunderbird version 115.5.0 (64-bit) SUPERNOVA using one of the pop3/smtp addresses - husbandATmydomain.me.uk and I receive emails from another of the domain's pop3/smtp addresses, sent by my wife from a Windows 10 laptop using Thunderbird, under the address wifeATmydomain.me.uk

Her Thunderbird a/c is correctly set up in her Thunderbird, to use the smtp server for her email address, wifeATmydomain.me.uk. There are no other addresses or identities set up on her thunderbird account. My thunderbird a/c is correctly set up to use the smtp server for husbandATmydomain.me.uk and has several other pop3/smtp addresses able to send addresses using their own smtp servers.

In MY Thunderbird address book my wife's address is given as wifeATmydomain.me.uk, with the display name "wifefirstname surname".

When I receive an email sent by my wife, to me, it appears in my Inbox with the Correspondents column showing MY name not hers. This means I am constantly missing emails from her. because her name is not visible in Correspondents column, but mine is there instead.

The Reply To: and From: addresses are correctly given as wifeATmydomain.me.uk when I examine the receive email details. It is only displayed with MY NAME, in the Correspondents column in the Message list header pane, using Classic View. Everything about her emails displays correctly in Message View, using Full Headers display.

The only thing I could find in research was to make sure her a/c was using the correct smtp server. It is.

How can I fix this please?
