I have the same error message and the advanced parameter does not help either.
Good news is: This does not happen when viewing the quota for a specific folder. For me the error only occurs when attempting to view the account quota by right clicking the root account node and not a folder.
here is a stack trace:
19:33:03 [IMAP] MailClient.Storage.Application.OperationException: Die Quotierungsinformationen konnten nicht gefunden werden, der Server antwortete mit einem Fehler: Client tried to access nonexistent namespace. (Mailbox name should probably be prefixed with: INBOX.) (0.001 + 0.000 secs)..
