Microsoft Outlook users are aware about the PST as well as OST files. But, they are not familiar with the term ‘NST’, which is also a storage file in MS Outlook 2016, 2013, 2010 & 2007. Therefore, in this blog, we are going to discuss about this .nst file extension of Outlook with its creation, .nst file location, etc. You can also preview data stored within NST File with the help of NST Viewer Tool.
An Office 365 NST file or .nst file extension is automatically created in Microsoft Outlook 2016, 2013, and all below versions when an individual configures the Office 365 account in Outlook. After configuration, Outlook synchronizes Office 365 group cached local copy in a new separate file named as GST or Group Storage File. It let users access Office 365 group in offline mode as OST works for mailbox folders. This GST and OST file are stored in same the folder on the local machine.
The amount of data synchronized in GST (using .nst as a file extension) is controlled or managed by Outlook slider. This GST with .nst file extension (also called as NST of Office 365 groups) stores only calendars and group conversation in it. Apart from this, shared mailbox and other mailbox folders can normally be accessed from OST file stored on the local machine.
