Eli needs to export files from his mailbox into a single file that is portable and can be backed up to removable media. Which file type will he use?

A PST file stores mailbox data—such as email, contacts, and calendar items—in one portable file that can be copied or backed up to removable media. An OST is an offline synchronization file, while MSG usually stores a single message; ZIP is a general-purpose archive rather than the mailbox export format described.
