How to Open NST File in Microsoft Outlook All Versions? – Solved

For Outlook users, you must be aware of the OST and PST file formats, but few people will be aware of the Microsoft Outlook NST file format. There is only one question: what is the NST file format? This blog describes NST files and their sites. It also explains how to create an NST file and open an NST file in Outlook.

Microsoft does not provide any direct option to import NST files in Outlook Classic versions. It allows users to open or import only a PST file. So, let’s explore all possible ways to open an NST file in Outlook directly.

What is An NST File?

The NST is essentially an extension of Outlook files and is stored on your local machine every time a user uses Office 365 in Outlook. Microsoft Outlook synchronizes a local Office 365 copy and stores it in a group storage table, also called a GST file, on your computer. The reason for creating a GST file is that the OST works in Microsoft Outlook, so that users can operate in offline mode in Office 365. To clarify the fact, both these files are stored in the same folder.

Outlook Slider manages and controls the synchronized data in GST files with the .nst extension. Normally, NST files store chats in groups and calendars, and store OST files, mailbox items, and other folders. Every time a user uses IBM Lotus Notes using Outlook Connector, an NST file is created on the local machine.
