Google Message Archiving Quick Start - Manual (Page 25)

Getting Started 25
Messages are on extension when their retention periods have expired but
they have not been deleted because you have turned off auto-purging.
• View how many of the messages on extension are also on hold (not available
to purge).
• Manually purge messages from the archive that are not on hold.
• Turn automatic purging on or off.
Reports
Message Archiving provides four different types of reports:
• Storage Overview An overview of mail flow, and current and historical
archive storage
• Storage Reports A month-by-month listing of the number and overall size of
archived messages and messages on extension
• Purge History A list of purge events
• Audit Reports Information about user activity in the archive
