MailEnable WebMail Inbox Gone

[cenlac]

When any mail user logs into webmail, it shows "Unable to load the Inbox because it does not exist on the hard disk". Users still can check email via a desktop client. I have run Plesk Reconfigurator, restarting everything, and still no fix. Does anyone know of a fix for this?

I ran Check disk permissions and this fixed the problem.

Could you be more specific on the fix please.

IS that a mailenable diagnostic?
Greatly appreciated.
