Is it possible to edit the content of archived items?

GFI Archiver is an archiving solution which enables companies to be compliant to legislations such as the Sarbanes-Oxley Act. This legislation states that companies should ensure that all inbound and outbound emails, particularly those pertaining to an audit or review, be kept for a period of seven years, during which time these records must be not be tampered with. 
 

Due to this fact, GFI Archiver does not give the option to edit the content of emails from any of its databases.
