Yes, it's the best way. On Win, the folder you're copying/pasting is C:\Users\<username>\AppData\Roaming\Thunderbird, and I recommend deleting that folder on the target drive before pasting (vs. overwriting it).

Great, will try this today.

I remember there being a way to start TB in offline mode. may not be important if I do not enter server details.

Thank you

Only way I know is to set startup state while TB is running.

This worked perfectly!

There are some old mail folders that will not delete, one is in the trash. I cannot right click and delete the trash, only delete the messages. i may start a new thread.

Thanks again
