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 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?

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?

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.

All of our "read" emails, --from all of our accounts -- have suddenly disappeared. All of the folders and subfolders are still present. We still get new email, but as soon as we read it, it's gone. We have had these same email accounts for years and have not made any changes. In Account Settings --> Synchronization & Storage --> "don't delete any messages" is checked. "Read" messages are still on our server.

So, 1) Why did this happen? 2) Is there any way we can get our messages back in Thunderbird?

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?

Cox.com has decided to no longer have their own email server and switched their accounts to yahoo. I can read my email directly on Yahoo, but can't get their imap to work. I changed the imap and smtp settings to yahoo. Also, the email login has changed and I changed that in Thunderbird. With Cox, the login was just "username" and now it is "username@cox.net". When I made these changes in the account settings, my email account has disappeared from the inbox, but it is still in account settings. I am using a unified inbox with several accounts.

Cox will not help me with this, and I have been on hold with yahoo for an hour with no response. I have been messing with this for two days so I hope you can help me.

Ubuntu 18.04.6 LTS and Thunderbird 102.11.0 (64bit) Archives in TB show 2021 and 2024 only but both are empty Archives.sbd contains 4 files: 1) 2021 (empty), 2) 2021.msf, 3) 2024 (apparently all missing emails are dumped here, but not in clear readable format) and 4) 2024.msf I did not intentionally archive the files; could be by accident clicking "A" but unlikely that I accidentally also had selected app. 3,000 emails. App. 60 mails were left (i.e. not archived) in inbox Tried to archive one file afterwards from inbox. OK, went correct to 2024 in the same folder as all the others. However, this mail was visible in Archives, 2024 in TB. I moved it back to inbox without any problem but strangely it still also is in Archives.sbd, 2024! HOW CAN I GET THE EMAILS (app. 3,000) FROM Archives.sbd, 2024 BACK TO TB?

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 ...).

I opened Thunderbird this morning and there were no issues. Closed it and just now reopened and I'm getting this message: Thunderbird detected a potential security threat and did not continue to live.thunderbird.net. If you visit this site, attackers could try to steal information like your passwords, emails, or credit card details.

It downloaded 28 emails but will not let me see/access them.

Can anyone help? Thanks, Linda

Windows 10. Thunderbird 115.7.0 32-bit. Email address is at hotmail.com, so it's an old account that's now at outlook.com This is a personal email account not related to any business nor to Office 365 or anything like that. I have had the account for decades.

Thunderbird quit working with my hotmail account this morning. It goes into an Invalid Password Loop, even when I respond with the correct password. I can logon to my hotmail account just fine with a browser. It's just not the same positive user experience as using Thunderbird.

I'm sure the problem must have to do with OAUTH2.

The outgoing SMTP server is outlook.com Server name is imap-mail.outlook.com Port is 993 Connection security is SSL/TLS Authentication method is Normal Password

Changing Authentication method to OAuth2 does not solve the problem. Instead I get a popup error message that's very hard to capture that is to the effect that "The imap server imap-mail.outlook.com does not support the selected authentication message". It's like I need to use a different imap server. I found one site that said to use outlook.office365.com but I don't really use office365. I may give that a try anyway.

I don't see any other account settings that seem relevant

I'm using Thunderbird 115.7.0 (64 bits). Cannot send messages from my email account: katy.vandenhoek@gmail.com. It says it cannot make connection to server smtp.gmail.com. Receiving emails is OK. The other emailaccounts are working OK. Looks like there is something wrong with the authentification. Reïnstalling Thunderbird didn't help.

I want to use thunderbird both for my personal mail and work mail, but I don't want to carry my work with me 24/7 so I don't want to be bothered by email notifications or "unread messages" indicators when I'm off work.

Right now it seems like I can only disable these things for the app as a whole, not per account, but I do want those notifications and indicators 24/7 for my personal account. Are there any more advanced controls for creating rules for how and when new and unread emails are notified to me on a per account basis?

I just noticed that if I check the SENT folder, some of the emails I sent have this text in the body part.

"This is a multi-part message in MIME format.

Content-Type: text/plain; charset=UTF-8; format=flowed Content-Transfer-Encoding: 8bit

[HERE THE CONTENT OF THE EMAIL I SENT]"

I'm wondering if they are sent like that, what the receiver will see and if there is a way to prevent it.

The email account is using IMAP and as far as I know it happen just to that specific email account. The emails are sent using Thunderbird. I'm using the latest version of Windows on a laptop. I'm using the following Thunderbird extensions (latest versions): - Compact Headers - Send Later - Mailmindr - Quicktext

When TB starts up, the only folders I can see are Recent. I can go to View/Folders and click ALL, and as soon as I move the mouse away from that menu item, it switches back to Recent. This started on version 115.09, but persists after I've "upgraded" to 115.10.1.

It has now (5/3/24 17:25 CDT) been 2-1/2 days since I submitted this problem, and no one has responded that it has even been noticed, much less solved. One of my two email accounts is a POP3, and the other is IMAP. The IMAP account Inbox doesn't even show up on the TB home screen. (If that info is of any help).

PLEASE ADVISE. My emails are an integral part of my business, and I cannot get to almost any them.

Thanks, rehawkpe

Hi,

while Thunderbird was updating to its latest version I lost the ability to scroll with my mouse wheel in all of its windows. This is really annoying.

How can this be fixed ?

Thanks so much, Andreas

BTW: In Firefox 119 there are no issues with mouse scrolling.

Have five email accounts, only 2 are set to check mail at startup. A change has taken the ability to click the down menu in the Get Messages icon to show all the accounts for a individual account check. With this change , if its intentional, it allows no obvious method to check these seldom used accounts. Checked the customization for the old "Get Message" with the down menu so I can return this feature and its not shown as a choice. If this is the intent then the "Account Settings" "Server Settings" to "Check for new messages at start up" which can be either checked or unchecked needs some attention. The missing down menu allowed these unchecked accounts to be checked only by selecting this down menu allowed clicking any of my 5 accounts account, and if memory is correct a choice to check all accounts.

If this is intentional change, how do I check individual accounts that are unchecked as still allowed in the settings.

Should this "Get Messages" with the down menu feature be returned or the "Account Setting / Server Settings" be changed to not allow a choice but require all accounts to be checked at start up, after a period of time, or by clicking "Get Messages" again to get newer messages all the time rather then by choice.

I'm requesting it be returned as a choice in the Customization items as I see no way to now check accounts with my current Account / Server settings as separate actions.

I just installed Thunderbird on a computer, current version, and it didn't update my address book or contact list off the server. How do I do this manually as I could not find something saying to "download contacts" or anything like that. There is the "Directory Server:" option but I don't know what that is or how to use it. I didn't do that on my other Thunderbird installation (Work Computer). My email server is Mail.com if that matters. Thanks

My environment - I am running Thunderbird 115.10.2 (64-bit), and Windows 10. - I have had NO Windows updates for at least two weeks.

The problem - About five days ago, outgoing messages (messages I was trying to send) started taking about 15 to 30 seconds before they were sent successfully.

- Today, I am unable to send messages. I can receive messages.

Actions I have taken 1. I re-installed Thunderbird after using Revo Uninstaller to uninstall it. 2. I contacted my ISP. They checked their settings, and have been unable to detect any error.

Please help!

I just asked this question a few minutes ago. This is a correction. It's only the font size in my signature that has shrunk since the latest Thunderbird update. The image in the signature is still the same size as it was before the update. I would like to know HOW to make the signature font size the same as the message font size.
