Thunderbird Support Forum

I'm moving from win 10 to 11 in new PC. I downloaded Thunderbird. I have hidden files showing in new PC so I found where it should be. When I look for the Thunderbird I downloaded it's not there in roaming...so I can't move my profile into the new computer. I have it on a drive read to install, but it's not showing up.

i have 2 computers running the latest thunderbird 115.10.1 (64-bit) one is in perfect layout exactly the way i want it the other has more layout issues than i have time to fix to make it back the way i want ( a fresh install ) i just want to copy the lay out not the accounts , not anything else is there a file or 2 i can just copy and put on the new computer ? and make thunderbird look normal

I am moving Thunderbird to a new PC, old was Win 10, new is Win 11. I installed Thunderbird on the new one, same version 115.10.2 though this is now 64 bit, old was 32 bit. I followed the instructions to move the profile by copying the Thunderbird folder onto aUSB stick then copying it to the new computer. The address book is there, but the local folders I had are not. Looking inFile explorer, I see that the Local Folders folder is there which contains all the folders I had, all populated, but there is also a Local Folders-1 there which does not, and this is the one Thunderbird is using. If I delete this folder, next time I start Thunderbird, it creates this folder again. I have obviously done something wrong, but cannot see what it is.

My wife got a new computer and I'm transferring her folders from her old windows 10 computer to her new Windows 11 computer. I have Thunderbird installed on the new computer with her account. Thunderbird on the Win10 comp is 32 bit and the Win11 comp is 64 bit. Both are the same version (115.10.02). On the old computer, in the MAIL folder there is "inbound.att.net" which has her mail files (Inbox, Sent, Drafts, etc.). Should I just copy all the files inside the "inbound.att.net" folder to the new computer?

Is there anything else I need to copy and paste from the old TB to the new TB folder? I'm guess that I will have to at lease copy and paste the abook.sqlite file from the old to the new. Any other folders or files.

Maybe I'm doing this wrong and there is an easier way to do this? I've read the article about moving data on the TB Support page but it doesn't mention anything about TB data from a Win10 32 bit to a Win11 64 bit computer. Will the difference in Win10 OS and TB 32 bit and the Win11 OS and TB 64 bit, be an issue.

Thank you so much for the help.

Hi:

I'm a longtime ubuntu (lubuntu, actually) user, and upgrading LTS versions every 2 years has been pretty easy til now: all I had to do was copy my .thunderbird folder to the home directory of the new system.

When I do that now for the pre-release version of lubuntu 24.04,, the new Thunderbird requires setting up the new profile from scratch, which is a pain, since I use T-bird for multiple accounts.

Is there an easier way of migrating my emails from my old profile to the new system?

Thanks!

Bill

Hello and Good Morning!

I need to transfer messages from one computer to another. I follow your instructions - export to .zip, file smaller than 2gb. On the second computer, I import the .zip file, the import seems to be successful, then I restart the program and I don't see the imported data anywhere (only Local Folders is created, but it is empty).

Could you please help me? Will be very, very helpful ;)
