Today one of our users had a problem with his mail-accounts.
He could not see any of his mail accounts and the appsuite always showed a connection error or timeout. We tried a view different things to exclude some possible reasons.
So other network and client, with or without VPN, and so on. The Logs on the mailserver didn’t show anything noticeable and every other account and user worked fine.
So we took a backup of the maildir-directory under /var/spool/dovecot and then deactivated the user for OX in the management-console. After that we reactivated it.
Then the mails come back in, but the calendar, contact and drive-data was lost.
So here is my question any possibility or idea how we can restore this data?
Thank you for reading!
