Has anyone else experienced an issue with orphaned .GRP files being present within a user's mail folder on the filesystem (i.e. \SmarterMail\Domains\Users\(username)\deleted items) but web mail reports that folder as empty?

 

We have auto-clean set on the "Deleted Items" folder so it should not have any mail in there older then 30 days, according to webmail that is true - however the files are present on the filesystem, they are several years old, and they do contain data.
