If you are searching for a tool to access PST files without Outlook, then I suggest you MSOutlookHelp PST File Viewer tool. This tool scans the PST file and its mailbox data items and allows users to view and read the contents of the PST file, such as contacts, emails, calendars, journals, tasks, and events. It has an advanced feature named Advanced Date Mail Filter which allows users to migrate emails and other Outlook data selectively, needs to select the option and set a particular date range to export and data will migrate between the dates. Apart from this, it is compatible with all Outlook versions, such as 2021, 2019, 2016, 2013, 2010, etc.
