There are several ways to move messages to archive mailboxes:
• Move or copy messages manually Mailbox users can manually move or copy messages from their primary mailbox or a .pst file to their archive mailbox. The archive mailbox appears as another mailbox or .pst file in Outlook and Outlook Web App.
• Move or copy messages using Inbox rules Mailbox users can create Inbox rules in Outlook or Outlook Web App to automatically move messages to a folder in their archive mailbox. To learn more, see Learn About Inbox Rules.
• Move messages using retention policies You can use retention policies to automatically move messages to the archive. Users can also apply a personal tag to move messages to the archive. For details about archive and retention policies, see Archive and retention policies later in this topic.
NoteNote:
Personal tags are available only in Outlook Web App and Outlook 2010 and later.
• Import messages from .pst files In Exchange 2013, you can use a mailbox import request to import messages from a .pst file to a user's archive or primary mailbox. For details, see Mailbox Import and Export Requests. You can also use the PST Capture tool to search for .pst files on computers in your organization and import .pst file data to users’ archives. Additionally, tools used to locate .pst files within an organization are also available from Microsoft partners. For a list of Microsoft partners for archiving, see "Archive and Compliance Partners" in Independent Software Vendors.
