# Restoring Mailboxes, Mailbox Items, Messages, or Public Folders to a PST File Using Exchange Archiving

Applies to: User Mailbox, Journal Mailbox

You can restore a mailbox, a message, or a mailbox item to a PST file.

The size of the PST file is limited based on the version of Microsoft Outlook that you use.

Microsoft Outlook Version | Maximum PST File Size
--- | ---
Microsoft Outlook versions older than 2003 | 1.5 GB
Microsoft Outlook 2003 or 2007 | 15 GB
Microsoft Outlook 2010 or 2013 | 30 GB
Microsoft Outlook 2016 or newer | 45 GB

If you try to restore a data set that is larger than the PST size limit, the restore will fail. You can choose to restore large data sets to multiple PST files that are less than or equal to the value that you define. These PST files cannot be larger than 45 GB.
