Форум поддержки Thunderbird

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.

in the contact field, how do i change the name of a contact field like custom properties or organizational properties to something else? i do not know how to add an image! So, go to address book, new contact, and you will see the fields custom properties and organizational properties towards the bottom.....Thank you...b³

I am struggling with Gmail and Yahoo mail account in TB these few days. I hit almost the same errors from both. I generated app password for Yahoo mail, and put it in when setting up new account. For connection security: SSL/TLS For authentication method: tried with Normal password, Encrypted password, and OAuth2 However, I am seeing the expected authentication window pop up when trying the OAuth2. For all three authentication method: errors are always the same --- unable to connect to your IMAP server. I've followed another instruction to change maximum number of server connections to cache into 1 or 10. Error messages were the same imap one. So, what should I do/try for next?

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??

Hello,

I have just imported my old email from Outlook to TB Local Folders. Everything works out except some of the email (not all) show a wrong date in the email list. The date show a future date like 2/7/2101, 6:28 AM. Please check the attached image. Any idea?

Since installing Ubuntu 23.10 on my new desktop pc, Thunderbird is failing to see the account details in .thunderbird I copied all the files from my backup into a new account directory (/home/cfi/.thunderbird/y4xyxmli.default), a technique that has worked many times in the past, but not this time. Previously, thunderbird has simply taken the settings from the backed up files and used those to connect to my organisation's mail server. Any ideas? How can I force Thunderbird to read the old account settings?

Many thanks.

Dzień Dobry

Poczta Thunderbird nie ściągą nowych wiadomości, usuwane teraz stare, wracają do folderów głównych. Przy odbieraniu wiadomości pojawia się komunikat jak na zdjęciu. Ostatnia wiadomość pobrano ok. 100razy.

After creating a IMAP email setup instead of the old pop3, I want to move my old folders over to the IMAP setup, but when clicking 'copy to', 'move to' or just simply dragging them nothing happens. No errors no nothing.

Whats wrong ?

I have two computers, one older with TB 115.9.0 32 bit, pop. The other has 115.9.0 64 bit, imap, same email address. I have tried to merge them, but when i do the Thunderbird Import folder has zero messages and no subfolders. I also tried changing the old TB to IMAP, didnt work: "configuration problem". Any help would be appreciated.

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?

Problem: Thunderbird hangs up on Macbook and iMac. It opens to the normal view, but if I try to do anything, I get the beachball of death. I used Mac migration assistant to install from Macbook to iMac. Before the installation, the Macbook Thunderbird worked fine, but after the installation, neither worked. My PC installation works fine, as does Apple Mail on my iOS devices, so it is not a provider problem.

Solutions tried: restarting in troubleshoot mode, restarting iMac, turning off access to Apple Contacts, turning off antivirus (Norton), creating new profile and copying existing mail data into the profile folder, and renaming various files in the profile folder.

Results: None of the solutions I tried provided access to my email. I can open the new profile, but that requires that I reenter all my email account information and copy the emails for each account into the new profile (I use POP). The problem may be with the prefs.js file, since if I rename it, Thunderbird doesn't hang, but would require me to reenter all my account info as if it were a new profile, and all preferences would be lost.

Question: What is the best solution for this problem? Is there anything that would work better than reentering the account info -- e.g., can I make any changes to prefs.js using a text editor or some other utility?

When I upgraded from MacOS Ventura to MacOS Sonoma, Thunderbird stopped working. Getting it to work the first time required me to use Apple's 2 Step Verification process to create an app-specific password. After the MacOS upgrade, that process was no longer available. Apple switched to 2 Factor Authentication, which is apparently different and incompatible with 2sv. The other websites and applications on my iMac have already switched to 2fa, and I'm not sure I can have both methods active on the same computer (but I've asked, Apple, anyway).

Is there a recent change in Thunderbird that would allow me to use 2fa instead of 2sv to access Thunderbird?

I have many years worth of emails in Thunderbird that I can no longer access. I can see the directory structure, and some of the email lists, but not the content.

Thanks for the help!
