An accepted message is not archived if it has a retention period of three days or less, but remains in the Accepted Email queue until it expires.

This functionality allows you to limit the life of message metadata to a value less than your company's maximum Account Retention. Email metadata (including the email header) is the associated information present in an email message. Metadata includes:

  • Date and time stamps
  • Mail server information
  • From / To addresses
  • Subject
  • Message-id

 

There are two different versions of the Metadata Preservation policies. The only difference between them is the time period length that can be applied to metadata.

 

Mimecast also retains additional metadata information, such as the policies applied to the message, delivery and rejection details, etc.

Although this is not commonly required, it is possible to remove the email metadata while preserving the contents of the email. Message retention can also be adjusted using Retention Adjustments.

Benefits

 

This policy should only be used if you'd like to keep email metadata for a period shorter that the Maximum Account Retention setting.
