What is NST File, and Why Convert NST to PST?

An .nst file ( Notes Storage Table or Group Storage Table) in Outlook is a local cache file that stores Microsoft 365 Group conversations, calendar, & shared data for offline access. Basic reasons to convert NST to PST include:

  • Can be directly opened and imported into Microsoft Outlook.
  • Fully independent of server connectivity.
  • Helpful for easy backup and migration.

Since there is no direct manual way available within Microsoft Outlook to convert an NST file (Office 365 Group mailbox) to a PST file, only the NST to PST Converter tool, an enterprise-grade solution, safely extracts mailbox data and makes it accessible again for you.
