I thik, that security risk will be huge, especially when tha email, moving form SPAM to Inbox back and forth is really virus carrier or ransomwere (not plain sapm). It will be unthinkable when ESET antispam scanner will be duplicating that email (with real virus or ransomware)in thousends..... Thus hope eset will fix this issue urgently (!). Now we have this option (see attached files) off and everything is ok, but we have ENDPOINT ver (with antispam) not ANTIVIRUS (without spam), therefore having premium version with main option off is nonsense....
Problem was only on shared inboxes, i e when one email address was (is) shared with many users, on client's Outlooks (the same mail for example contact@abc.com)
In minutes we had over thousands emails multiplied (initially one mail was moved to SPAM, afert a minute was moved to Inbox, and afterwards two emails were moved to SPAM, then Outlooks at other users stated to replicate, and in the minutese one email was changed to 1300 copies....
