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

I am unable to send emails. I am asked to enter my password and have tried many times. The instructions to enter my password just keeps repeating over and over. I am at a loss as to what to do. Any suggestions?

For the last 6 months, my ip gets blocked from my website server about once a month. This causes me to locked out of my website until inmotion unblocks my ip. It works fine for about a month and then ip blocked again The conversation below was with my hosting company Inmotion hosting

Was there anything else I could assist with today? (4:37:20 PM) Alan Johnston: What can be done so this does not keep happening about every month (4:38:32 PM) Andrea J.: You will need to locate the device that is having the login issue, (4:39:14 PM) Alan Johnston: That is the only email related to this site and It is me.

(4:41:17 PM) Andrea J.: If your IP is repeatedly being blocked, there is an issue with the mail client's connection.

I've been using TB on 2 of my smaller email accounts for several months and really like the way it operates. I'm nearly ready to add my main email account (web-based Outlook) to TB but have one final question. If I add the account to TB, give it a fair try, and just don't like the results, can I simply delete that account from TB and go back to accessing it via its website? I have confirmed that POP is disabled for my Outlook account so I understand all email remains on the server until I remove it. I also understand TB would leave the email from the account on the same server, again pending some action I might take to remove it. So it would seem that I could delete the account from TB and revert to web-based access for the account, just as I'm doing now, and the folders and saved emails would still be there. Am I overlooking anything?

I want to prepare emails in advance (in the Outbox folder?) and have Thunderbird send them later, at a time that I specify when I prepare them. I looked at the Events and Tasks tab but I can't see how to do what I want with a task. All the prepared emails can be sent at the same time. Can it be done? Thanks Peter M

I clicked the 'a' key on a folder in my email and a stack of emails disappeared. Some unread and some requiring a response! They're not in the archive folder.

Thanks!

Hyperlink insertion only works in troubleshoot modes but not in main mode even if all extensions and hardware acceleration are turned off (used this guide: https://support.mozilla.org/en-US/kb/troubleshoot-mode-thunderbird#w_the-problem-no-longer-happens-in-troubleshoot-mode)

Please help me.

Thank you!

I upgraded to Thunderbird 115.10.0 (x64) earlier today and now the program is no longer closing completely (I've tried using the X at the top right of the window, and I've also tried File menu -> Exit). I first discovered this when I was using CCleaner to clean my temporary items and it asked me if I wanted to close Thunderbird after I had already closed it. I then checked my running processes and there are three Thunderbird processes that remain after the program has supposedy closed (Task Manager screenshot attached).

Any help with this seemingly new bug is greatly appreciated!

Much thanks, -Snipe

I can't receive emails at any address from those in Thunderbird. I have several addresses, some in Gmail but not all. And in each of them I get this message: The STAT command did not succeed. Error getting message number and sizes. Mail server pop.gmail.com responded: [AUTH] Invalid credentials. I am using version 115.5.2

Hi, Excuse my poor English (I am French). Linux Mint 21.3 Cinnamon (64), Thunderbird 115.9.0 (64) no added module - Installation from the Mint list of software. My problem : regardless of the provider (Proton, Gmail, Outlook, GMX - in IMAP), the message menu bar (see <https://support.mozilla.org/fr/kb/personnaliser-la-liste-des -messages#thunderbird:linux:tb115>) does not appear. How to make it reappear ? I think I have tried all the configuration menus and possible right clicks within Thunderbird ; I haven't found anything on the Net ; starting in safe mode did not change anything. I come from Windows 10 where I didn't have this problem. Thanks in advance for your help

When I print an email, TB prints all of this technical jargon such as X-MS-Exchange lines, and what seems to be the background handshake protocols behind the email. I just want the contents of the email printed. May I ask how I fix this, please?

I updated Thunderbird to the latest version and now I have a problem that continues to remain after closing the process.

Thunderbird 115.10.0 64bit (Build ID 20240412173147) OS Windows_NT 10.0 22631

Old computer: Windows 10 Pro, 64 bit Thunderbird 115.10.0 32-bit (Don't know why it's 32-bit version on a 64-bit computer or whether that's relevant)

The Profiles folder is here (with 5 profiles): C:\Users\<User>\AppData\Roaming\Thunderbird\Profiles

The new computer is Windows 11 Pro, 64-bit I just installed Thunderbird (V115.10.0 (64-bit) on the new computer.

On the new computer, the Profiles folder is here: C:\Users\<User>\AppData\Roaming\Thunderbird\Profiles

I followed the directions here https://support.mozilla.org/en-US/kb/moving-thunderbird-data-to-a-new-computer

I basically took the Profiles folder that came with the Thunderbird installation, renamed it (Profiles.orig) and copied in the Profiles folder from the old computer in its place. When I start up Thunderbird, I get this error message:

           Your Thunderbird profile cannon be loaded.  It may be missing or inaccessible

What am I doing wrong? I've updated Thunderbird on the old computer and copied the Profiles folder over to the new computer again. Same result.

Could it be 1. an issue with the user name on the old computer is different than the one I'm using on the new computer? 2. All files on the new computer are set up as local (the user on the old computer started out as a Microsoft user but I made it local so as not to have to use OneDrive).

I'm stumped. Any help will be very much appreciated. If you need any more details I'm happy to provide them.

I've been trying out Thunderbird and Spark for the past few weeks, and decided to go with Thunderbird to replace Windows Mail. After uninstalling Spark, I changed all my email passwords, and now Thunderbird can't connect. I deleted my Google and Xfinity email accounts from Thunderbird, then closed and reopened the program, but I'm still getting this error from Google when I fill in the credential info it automatically asks for when re-adding it to my account:

"400. That’s an error.

The server cannot process the request because it is malformed. It should not be retried. That’s all we know."

On the "set up your existing email address" page in Thunderbird, I'm getting this error (see image), even though the copy/pasted password works fine when logging directly into Google.

I also can't reconnect to Xfinity at all. The 3rd party box is checked in their system, but when Thunderbird tries to connect, it looks like it's auto-filling and submitting a password on my behalf, without stopping on that screen so I can change it.

I did this: https://support.mozilla.org/en-US/kb/password-manager-remember-delete-change-tb

And tried all of the suggestions on this post: https://support.mozilla.org/en-US/questions/1434503

What am I missing?

Hello. In our company, every employee has an IMAP account, but over time the IMAP profile takes up too much space on the hard drive (100-200GB per user...). What can we do to have more storage space? Can we delete the file? Or will all emails also be deleted from the server?

Hi! the last version of thunderbird (115.4.1 on Windows 10) don't remember the last mail selected when I change the folder. I try to explain better, for example if I go to the inbox and select one mail (for example the last mail received), if I go to another folder and then go back to the inbox folder the view is another one and I have to scroll down to find again the last mail received. I 've the same problem on my office computer so I think it's a problem common... This issue is come since I installed the Supernova versions.... Thanks!

ps this problem seems to be present only in the inbox folder if the last message received is in the bottom (mail from the oldest to the newest) If I change the sort with the colum date to have the last message in the top (mail from the newest to the oldest), the problem disappear

I recently moved to a new Windows machine and can not send mail from either hotmail or gmail accounts. I am able to send and receive from my account at outlook.office.com, but hotmail uses outlook.office365.com as the mail server.

Thunderbird Version: 115.10.0 Windows 11 Version: 23H2

The message I receive when trying to send is: Sending of the message failed peer's certificate has an invalid signature the configuration related to smtp.gmail.com must be corrected (also for smtp.office365.com)

I did try all of the fixes advised here, as the error message certainly matched what I was seeing: https://support.mozilla.org/en-US/questions/1295861 so my settings in TB are currently: security.tls.version.min = 1 security.tls.version.enable-deprecated = true

The final suggestion in the above thread was to move back to Thunderbird version 68.11.0, which I will try if nothing comes of this thread by the weekend.

When I'm searching Community Discussions, it would help a lot to be able to sort the discussions by date or at least see when a discussion was started without having to open each discussion individually. Is there a way to do this? The answers in older discussions, pertaining to older versions of Thunderbird/Firefox, may no longer apply and it is frustrating to try and find pertinent discussions when you have to open and close each discussion looking for answers.
