Best method of sharing Profile

[Gordon]

I have a dual-boot Windows XP and Kubuntu machine. I have shared the
Documents store by using the Ext2IFS utility on XP, and now I need to
share the Thunderbird data between the two.
My question is:
Is it best to share the profiles BEFORE any data is input, or can i do
it safely after one or other of the profiles has had data put into it?

thanks

My suggestion is :
1st. setup your TB in windows:
create a profile which must be in a shared drive ( between Windows & Linux )
set up all accounts .

when you will finish your work in windows , reboot machine and login to
Linux

Setup your mail accounts ( no need to worry about profile folder location )
after completing TB , close it , no need to download mails
manually change folder access property of profile folder located in
shared drive to read+modify .
Now open TB in offline mode.
goto Edit>Account settings
Select server settings for 1st account.
click on 'browse' button (Just under 'Local folders' label ), point to
to folder for that account which is
within profile folder at shared drive

do same for other accounts also.

for Newsgroup , you also have change 'newsrc file' location in same way
to point it to shared newsrc file located within shared profile folder
for that newsgroup
