We had a user quit recently. Three days ago I copied his entire Maildir folder to another user to that user's Maildir/.JoesEmail. I changed ownership and made the permission 'chmod -R og-rwx .', just like all the other files/directories of the new owner. This didn't work to show the new folder. Today, in his Thunderbird client, I subscribed to the 'JoesEmail' folder. I restarted dovecot and restarted Thunderbird.
In Thunderbird, the 'JoesEmail' folder now shows, but it is empty and shows none of the subordinate mail folders. I ran 'doveadm index -u newowner JoesEmail' and 'doveadm force-resync -u newowner JoesEmail'. This didn't help.
I did this once before with a previous user who quit and only changed ownership, no subscribing, no doveadm, and that worked.
What am I doing wrong?
