I run the follow command:
source mailcow.conf
docker-compose exec -it mysql-mailcow mysql -u ${DBUSER} -p${DBPASS} ${DBNAME}
Check the numer of records in these tables:
select * from mailbox;
select * from quota2;
The number of row must be the same but in my case mailbox contain 40 row while quota2 41 records.
I find easily which record exist in quota2 but not in mailbox table and delete it.
After the drop row i’m able to see all mailboxes in the tab.
Many thanks to user https://t.me/FreddleSpl0it on telegram. He found the right solution while I run only the commands he suggest.
