Putting it all together
As you can see, the three capabilities are designed to work together to form a
comprehensive corporate compliance strategy. There is a centralized email storage location that makes
search easier and an automated email archiving and deletion mechanism to help manage
content without user intervention, thereby reducing human error or oversight. Finally, there
is a mechanism to enforce preservation of content that overrides any other action to
modify or destroy that content. Let us now look in detail at the actual technologies that provide
these three capabilities.
Personal archive
We think of the personal archive as the foundational technology that supports compliance.
The personal archive is sometimes referred to as the online archive or Exchange Online
Archiving (EOA) if it is implemented as a stand-alone Exchange Online workload.
Before the introduction of the personal archive, users had limited mailbox sizes because of
the need to manage the performance of Exchange. That is why Personal Storage Tables (PSTs)
became popular. Users either delete emails to free up space in their mailbox or move them to
.pst files. Both of these actions are major causes of concern when it comes to compliance.
Exchange Online Plan 1 provides a 25 GB storage that is shared between the primary
mailbox and the archive mailbox. Exchange Online Plan 2 provides unlimited archive space that
is separate from a 25 GB primary mailbox.
Remember that Exchange Online Archiving provides each user with an unlimited amount
of archive mailbox space that is initially provisioned as 100 GB, and it is accessible
through Outlook and Outlook Web App.
Therefore, the first step to compliance remediation is to assign users a personal archive.
You can choose to do this for every user or only for certain users. Provisioning a personal
archive can be done through the EAC, ECP, EMC, or Windows PowerShell.
Messaging Records Management
After you have provided users with a generous personal archive, you might still need to
implement MRM to automatically archive or dispose of email content. MRM is
accomplished through retention tags and retention policies.
