Hi,
When you have a big buch of subfolders and they are archuived. They are buch of mbox files in one FOLDER. Now to make
access for archived mail easier to read to users that made their own folder structure it would be OK to add a feature when archiving.
Now Thunderbird is OpenSource and reads MBOX on the FLY. Since all arhives folders are below another. You could maybe add
archiving in true form by making SBD folders in current archive folders. So you would finally have:
INBOX.sbd (Folder)
INBOX.MBOX (Email in inbox)
INBOX.SBD/Officemail,MBOX (Subfolder in INBOX)
When you add these archives for usage you get:
INBOX
INBOX.1
INBOX.2.A
INBOX.3.B
INBOX.4..C
Looks ok. I could get used to it. But not sure how many users would.
