Thunderbird 社群討論區

I have 3 computers and I want to make sure Thunderbird is synchronized on all 3. Yes, I have checked your forums for help. Here’s my configuration:

Main PC – used daily. Thunderbird has 4 email accounts. One is IMAP, the others are POP. Backup PC – Used only occasionally. files on this computer are synchronized with the Main PC about once per month. The email accounts are the same as the main computer. Laptop – Used only occasionally. files on this computer are synchronized with the Main PC about once per month. The email accounts are the same as the main computer.

I have read articles on how to move profiles, but I have not come across one that does what I want to do. Also, I am confused about whether filters can be duplicated on more than one computer. I have seen suggestions to just use IMAP (which might work for some, but not all, accounts), but that doesn’t address how to copy filters and keep them synchronized.

Here’s what I would like to do.

Step 1: Back up Main PC Step 2: Copy Thunderbird emails and filters from that backup to the Backup PC Step 3: Copy Thunderbird emails and filters from that backup to the Laptop.

When all steps are completed, I would expect that if I open Thunderbird on either the Backup PC or the Laptop that all messages, folders, and filers would be exactly like those on the Main PC.

Is this possible? If so, what must I do to ensure everything works as I would like?

Thanks, Alan

Hello I have Thunderbird on my Laptop. When I try to install it on my PC I got the message: server not found. I use the same parameters than the ones on my laptop. Can I synchronize these parameters on my PC? Regards Gabriel

For some years I have transferred the current Thunderbird data profiles from a desktop computer to a laptop once a year when traveling. When returning home six months later I have been able to delete the old data profiles in the desktop and transfer the 'current data' from the laptop over. This system has worked for some years however after recently upgrading the laptop to the latest version (140.2.1esr) and installing the latest version on the desktop (both 140.2.1esr) the transfer of data fails. The program identifies the data on the laptop as an "old program". Could someone point me in the right direction and advise where I am going wrong at the moment. Thanks in anticipation , Bruce

I am trying to export my profile and associated information to my new PC. When i follow the instructions given for export I can't find a file that ends xxxxxxxxx.default-release. This is what I have found: C:\Users\susan\AppData\Roaming\Thunderbird\Profiles\epkxk9e0.default Obviously it doesn't have the default ending with -release. How do I get to that? If I can export to a .zip file can I upload that to the new PC?

Several Months ago I bought a new W11 HP laptop and successfully followed the following procedure provided by David to get my TB profile/data and all files and folders onto this new computer. Here is the link for moving a profile in Windows when installed in default location:

https://support.mozilla.org/en-US/kb/moving-thunderbird-data-to-a-new-computer

here is the info in brief steps:

 1.  ensure thunderbird is NOT running on old machine
  2. enter %appdata% in search window on task bar and press Enter key
   3.this should open windows file explorer in Appdata\roaming folder
  4. highlight the Thunderbird folder and copy to external media
  5. ensure thunderbird is installed on second computer and NOT running
  6. enter %appdata% in search window on task bar and press Enter key
  7.you should be in Appdata\roaming folder , copy&paste the exported Thunderbird folder there. This may prompt to overwrite an existing folder of same name. allow it
  8. start Thunderbird and all should be there 

There were a few hiccups but it works great! I now want to make sure I am creating a back up copy to save on a flash drive just in case something happens. I followed steps 1-3 above and that should be my back up..RIGHT? I did that and saved it in a folder labeled TB back up Profile and a date. My old was was to just back up the TB profile folder alone but I think this one saves everything. (accounts, folders, Local etc. Have I done it right???

Hi, i copied my Thunderbird (windows 10 Prof)) to a new Notebook (windows 11 Prof) by overrighting the Standard-Profilfolders (in ROAMING and LOCAL) of the new Installation with the Folders of the old Installation (both are Version 146.0.1 but old is 32-Bit and new is 64-Bit) I use more than 2 accounts, and in some accounts, I created subfolders in the 'In' folder to preselect the emails by rules after they arrive Result is: alls Subfolders are missing and some accounts' 'In' Folder are empty. The Account settings seems to be corrct, means i can load new EMails even if the IN-Folder is empty. But i miss the exosting EMails there and the Subfolders content.

how to convert from v128.6.2 esr(32bit) to v137.0.1 (64bit)

In the past, to update the mail on another computer I simply copied the profile folder. But the new installation is now version 137.0.1 and the profile structure is very different. How do I bring the accounts and all existing mail to my new computer?

thanks for your help.

The summary says it all. My T-bird acc't combines both outlook and gmail and now I wish to transfer the data into a new T-Bird (account?) on a new computer. I'm going from an ASUS Zenbook to a HP Omnibook AI.

Many thanks ! I should sign my name as "Totally Lost". Regards, Andre

Hi all.

Previously, when moving to a new computer (Windows 11) with Thunderbird, I would install a new instance of Thunderbird on the new computer and run it once. This created the default Thunderbird profile in the Profiles directory. I would then copy the contents of the existing Thunderbird profile into the new one. This allowed Thunderbird to be fully operational with all accounts and filters working, requiring no further setup.

In version 140, I have followed the same process. While I do see all of the email accounts, they are not functioning.

Any advice on how to do a migration with Thunderbird 140 version?

I am running Thunderbird 140.8.1esr on macOS Tahoe 26.3

I created an IMAP account in Thunderbird to replace a POP account

I want to copy the Thunderbird message filters from the POP account to the IMAP account

I read articles on Mozilla Support and these said to copy the msgFilterRules.dat file but I cannot find this file

How can I copy the message filters?

I transferred content via a Time machine backup of my old macBookPro (Ventura 13.6) to my new macBookPro (Sequoia 15.6.1). The Thunderbird folder is identical on both computers and contains two profiles: a newer 9389qbc0.defalut-release and an older r13n4n5e.default. The former presumably is active on my old computer and is the one I want to view/use on the new computer. However, the older version appears on my new computer. How do I get Thunderbird on the new computer to recognize and load the newer profile? Thanks much for any assistance!

I just deleted the folder C:\Users\alan\AppData\Roaming\Thunderbird and replaced it with a backup I made a few days ago. To my surprise, when I opened Thunderbird, I could see messages that I'd downloaded today. What is going on?

My hard drive is going to have to be replaced, how do I move everything to a new hard drive. I pay my bills from folders I have added in 'Tbird so it is imperative that I move it all intact AND that I have access to all of it after I do manage to relocate it to a fresh hard drive. Thanks, God bless....Arthur Kelly

Hi all, I have a new Computer and I'd like to transfer my Thunderbird installation with the complete settings (folders, mails, archives, address-book, ...). Also the calender would be of interest, because I have some settings which I want to keep. Is there any way to do this? I have access to my old computer, so I could export everything there and import that on the new one, but I did not find something to do that. Can you help me? Regards, Gerhard

Have TB on my laptop (146.0.1 (64-bit) on Win11) all set up the way I want it. Would like to "clone" those settings/profiles to my desktop. AI site said, "Copy profiles folder and profiles.ini to the new machine." Didn't work. Asking me to set up from scratch. Laptop is on "standard" edition, think desktop is on beta. Is that the problem? What do I need to do?

I've been using Thunderbird for years under windows 7 and keep my data on a separate drive. Is it possible to migrate or move the whole program and data base into Linux at a later date? I haven't used Linux yet, but need to know if it's possible to successfully make the move before I jump. Thank you.

I didn't find anything quite like this in the forums.
