I am Zimbra newbie so please bear with me...
So I shared an account using:
zmmailbox -z -m email@example.com mfg / account firstname.lastname@example.org rwixd
zmmailbox -z -m email@example.com cm /shared firstname.lastname@example.org /
But when I reply to a mail 'on behalf of' from user inbox,
mail in shared Sent folder is saved as unread.
Is it a bug or am I doing something wrong?
