We just migrated from Exchange to Zimbra, but there were some problems with the migration tool. Long story short is some users have duplicate messages but one of those is bad (blob not found). I can run zmblobchk tool and see lots of errors. So how do I get rid of these blobs that don't exist? I don't need to keep any of it, as it's just duplicate information from times when the migration process crashed and had to be restarted.
