Thunderbird Support Forum

For some reason, my Thunderbird recently "updated" to version 115.10.2, and the "About Thunderbird" dialog says that it is on the "esr update channel." I can find no information about the esr channel. However, when I start Thunderbird, it displays the "Welcome to Thunderbird DAILY" screen. Am I correct that this is an error? If I were really on the daily channel, I think that the version number should be higher.

Been using Outlook, but am having issues. Decided to try TBird. Got the email part set up (far as I can tell). Calendar and Address book are a different story. Calendar: Using Google Calendar as primary calendar. Consists of an appointment, birthday, and holiday calendars. Created a new calendar and entered the URL for my Google Calendar. It showed up in TBird apparently OK. Created ANOTHER calendar and entered URL for Googles stock Holiday calendar. It also seemed to show up OK. Tried to do what I did with those calendars to add my Birthday Calendar, but Google uses data from Google Contacts to create that calendar. Can't figure how to add that data. HELP? Address book: Exported Google Contacts Data to a CSV file. Tried BOTH Outlook CSV and Google CSV exports. NEITHER produced a CSV file ANYWHERE Close to what TBird appeared to want, based on what showed up on the "fields" page that appeared after I chose the CSV filename. Moving data around in a spreadsheet is a Royal pain. Isn't there a Google Contacts CSV export file that more closely approximates the arrangement that TBird WANTS?

""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.

As of today Cox is moving all email services to Yahoo. I have been using Thunderbird for Cox.net email. I have about 40 existing folders under cox.net. Yahoo now has Cox.net and is providing my new emails so I still have the same email address and can access it through webmail. What is the best way to transition this from the old Cox cox.net to the new Yahoo cox.net on Thunderbird and keep all existing folders? Thank You

Have two computer with same email. My Wife's computer password got corrupted and unable to get messages. I deleted TB and deleted any reference to Thunderbird in the registry. Turn off and restarted PC, downloaded new install and run and all the setting from before automatically were in place and still could not get pass the password issue. My computer does not have any password.

My wife's PC, under setting, does not have any saved passwords or a Primary password or even the "Use a Primary Password" checked. If it is checked there is nothing there. It just will not get passed the password issue being always asked when trying to "Get Messages".

How do you get rid of all the infor, setting, password requirements and to be able to restart with a clean Thunderbird install or get passed the password issue? Making my brain hurt.

Hi there,

I had 755 emails in a label in one of my two gmail accounts. I linked by gmail accounts in thunderbird and selected 'copy' of the label from one account to the other. However, only 359 have transferred. I've tried again and nothing has changed. Its made a big mess of both my gmail accounts.

As I move from an old computer to a new computer, I can't seem to remember my old computer's T-bird password, which asks for the new computer download setup. Where can I find the password on my old computer?

Hello,

I was using the previous version of Thunderbird (115.10.0) (64-bit), which was crashing upon exit. I tried to update by clicking on Help and About Thunderbird, but it didn't automatically update to the newer version (115.10.1 (64-bit)). So the instructions I followed was do download the new version. However, when I open the new version, all my email accounts and calendars are missing. How do I restore my old profile?

If I try to import Mail Message in Outlook 2016, the progress will not proceed at 0%

Both Outlook and Thunderbird were running on 64bit

How to solve this?

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 currently have a Outlook account and a Jagwireless email account. I am trying to move it to Thunderbird. I can now receive my Jagwireless Emails in Thunderbird but I can not send emails through Thunderbird. Any ideas how to fix this?

I'm trying to migrate Thunderbird from my old PC/Windows 10 to my brand-new PC/Windows 10, following the step-by-step instructions on https://support.mozilla.org/en-US/kb/moving-thunderbird-data-to-a-new-computer. I followed those instructions to the letter (multiple times) but can't get it to work. Are there more recent (and perhaps more complete) instructions to be found elsewhere? Does anyone else have the same?

I have made a copy of my old TB profile folder on a backup stick (it is titled 'Thunderbird', and inside that folder is a folder titled 'Profiles' that contains a number of folders including the most recent profile that I am still using with my old PC. The difficulty is getting this backed up profile info installed on my new 'destination' computer.

Any suggestions would be greatly appreciated.

Cox has tranferred my email accounts to Yahoo. I need to know how to connect back to Thunderbird. Had a discussion on your FB group with ANJE YELF.. She said to leave a message here and she would get back to me on how to do that. I have imap.

Moved to new country (UK) took TB data with me as instructed. Installed TB did put in email data. Uploaded TB data as per instructions. Opened TB and put in email password etc. All my current emails show up no problems and email account appears to work but none of the uploaded data appears even though it took 15 min to upload. It feels like it was uploaded to the 'wrong' place but I uploaded the data it to the TB folder as instructed. Any idea what I did wrong??
