How to export items to an archive file in Outlook (Mac and PC)

Windows

If you want to back up the message folders locally (in addition to keeping them on the server), you can export the items to a .pst file that you can restore later as needed and use by importing.

Please follow the instructions for Windows computers here.

MacOS

To back up the message folders on a Mac computer you can manually archive to an Outlook for Mac Data File (.olm) on your Mac — your email messages, contacts, and other items. You can save an .olm file to any location on your Mac or on a different machine for safekeeping.

Please follow the instructions for Apple Mac computers here.
