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
Microsoft Outlook 2003 or 2007
Microsoft Outlook 2010 or 2013
Microsoft Outlook 2016 or newer
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.
Before You Begin
