Exchange Online Archiving is a Microsoft-hosted service that archives mailboxes from Exchange Online or Exchange Server.

Capabilities and Limitations

Exchange Online Archiving maintains a parallel mailbox (called the archive mailbox) for items archived from a user or shared primary mailbox. This feature limits primary mailbox size and helps centrally enforce organizational policy for mail and related content. Users can view and search their archive mailboxes, while organizations can enforce retention policies and legal holds and perform eDiscovery searches on archived content.

The separate Office 365 Import Service allows the import of existing on-premises archives to Exchange Online Archiving via direct upload of e-mail personal store (PST) files to Microsoft servers or shipping the data to Microsoft on physical disks, to speed initial migration of mailboxes from on-premises.
