That is the problem.  I cannot reproduce (reliably or at all).  It might be months before we hear about it.  It has been happening for about two years.  Always chalked it up to user error.  But I can't say that it is or isn't.

If you can reliably reproduce the problem on a test account, enable telemetry logging to capture what the client is doing.

Upon further review everything is gone for that mailbox including: cyrus.cache, cyrus.header, cyrus.index.  Backups contain everything including past emails and the core Cyrus files.  If the mailbox contained other mailboxes they are not affected.  Reconstructing it corrects the issue, luckily our backups do not propagate deletes.
