I need to move several GB of email out of an account that is going away. Too much to important into one of my other email accounts, due to quotas. They are in mbox format in a linux mailserver. One solution is to store it in "Local Folders". But I need that email to be accessible from multiple computers (work, laptop, home). These email folders are in a pretty deep hierarchy. I found that I can move my Local Folders location to a cloud storage service, and the ImportExportTools lets me import them. It took a bit of manual work (I had to do it one directory at a time). But it works, and when I open Thunderbird on another computer, it sees them. Wonderful. Problem: when I make changes to these local folders from one mail client, the other mail client doesn't see them, unless I exit and restart Thunderbird. That's pretty annyoing, because then I have to sign in to the various email accounts I use. Is there any way to force Local Folders to refresh or re-sync contents without actually exiting?
