click tools>import>import from a file and then follow the menus for addressbook and select the sqlite option and then locate and select the abook.sqlite file from old profile. Repeat the process for the history.sqlite file. AND, if you're comfortable with windows file explorer, just exit thunderbird, and copy the abook.sqlite and history.sqlite files from old profile and paste into new profile and restart thunderbird.

i just tryed and cant find old profile. then tryed to import address book and got an error msg thanks

i got far as a window called "select an addres book file" but dont know where to look for it.

i then tryed ti import it another way but got an error,

If you can start thunderbird on old PC, do this: - click help>troubleshootinginformation - scroll down to 'profile folder' and click 'open folder' - exit thunderbird - you are now in the profile. note the exact location on the disc. you are in the folder with abook.sqlite and history.sqlite. copy both to external media and you can then follow previous steps to import to your new pc.

ok i'll; try that and be back here in cpouple of hours...thjanks

hi ive done that now but only managed to import 10 addresses, there are more like 100 on the other pc which should be coppied successfully

also what should i do with "history" file i copied

were getting there, thanks

OK, you used the tool>import for abook.sqlite and there were only 10 addresses? Repeat the process of tools>import for the history.sqllite file and see if that helps.

ANOTHER approach, much simpler, is to shut thunderbird down and do the copy with windows file explorer. You now know where the old profile is. just use windows file explorer to copy the abook.sqlite and history.sqlite to external media. then go to new pc and paste them into the new profile, overwriting the existent file. That guarantees you get it all.

I DID THe import again but no help , i couldnt copy to a flash grive for some reason it was not seen in "send to" so i emailed it to myseff. could that be the proiblem?

can you tell me please what was the history copy for?

now i see ive lost all my folders, since your advice i reinstalled TB [obviously a bad move but i assumed it would find everything in for me like its done before [and it was getting quite flakey]

can you tell me the route to the TB folder pls. i did as you suggested but only noted it is on C drive thanks again

on the old computer, I suggest using copy and paste instead of 'send to' - that's more reliable the history file is the one that thunderbird refers to as collected addresses to get the exact location for your profile, click help>troubleshootinginformation, scroll down to 'profile folder' and click 'open folder' - you will then be in the profile and you can see the exact location, beginning at c:\users\<yourid>\appdata\roaming.... etc.

thanks David, will do that tomorrow and be back

hi, finally managed to get the 2 files onto a memory stick [there wre some p[roblems at first] will try to complete it tomorrow. i copied both files named "folder" in hope they will be my lost folders as mentioned thanks

i did exactly that and it worked. thanks very much, should i do same thing withe folder files to get my folders back?

Yes, that works. Be sure to paste into the Mail\Local Folders folder. Pasting into an account folder would overlay messages already there.

in my acct i can go >mail> outlook office 365.com.

or >local folders

i guess this is becauase TB collects my mail from outlook.com. which folders should i overwrire please

thanks

I recommend Local Folders to ensure not losing messages in the account. Later, if desired, you can copy them to the account

hi,

am still trying to get my missing folders installed but the unopened folder keeps ending up in the side bar/window where i normally have many folders full of mails

i copy/overwrite foldercache.json and foldertree.json. i put those folders into profile folder>mail>local folders

thanks if you can say what i'm doing wrong
