Under what conditions should this be done? When should we decide to do this? We have ArchiveAccessEnabled set to false and we are able to enable archives.
Thanks!

Hi
The archive is enabled to meet your compliance requirements, such as keeping email for 1 year and moving those items out of your primary mailbox and into your personal archive (see enabling retention policies for more details - blogs.technet.com/.../enabling-retention-policies-office-365.aspx).
The personal archive is only available online, so is not cached to your local .ost file like your primary mailbox. So in order for the .ost file not to grow too large that it will get corrupted (Outlook 2007 for example is 20GB, see support.microsoft.com/.../832925 for more details) you move items out of your primary mailbox and into personal archive.
You also have to think about the storage on your local laptops and desktops as when you want to start moving items into your personal archive in order to keep the .ost file to a minimum.
I also assume you are using running in hybrid mode (formally rich coexistence) and looking to have on-prem mailboxes with an personal archive in the cloud?
