Are you a regular user of Microsoft Outlook? If so, then I think you might be familiar with the PST and OST file formats and extensions. But have you ever heard of an NST file? Most users will say “no.” However, you should have some knowledge of every file format. This post is going to give you a clear concept of what an NST file is and how to create and open .NST formatted file in MS Outlook.
What exactly is an .NST file format in Outlook?
Fundamentally, an NST is an Outlook data format that is saved on the desktop’s local disk once a subscriber sets up an Office 365 account in Outlook. Microsoft Outlook integrates the native edition of Office 365 and saves it on the device in a “Group Storage Table” (GST file) format.
The GST file was created to let users operate in an offline mode on Office 365, similar to how an OST file functions for MS Outlook. To clarify your concerns, both the OST and GST files are kept in a similar location.

Often, the NST file is used to save talks in teams and calendars, whereas the OST file is used to hold inbox contents as well as other directories. If one user connects to “Lotus Notes” through the Outlook Connector, NST files are created on the device’s local drive.

In MS Outlook, how do you open an NST file?
Because NST file formats are Office 365’s cached offline data, they are constantly in a quite inaccessible state. To see .NST files in the Outlook application, users must first convert NST to PST format and then import them into Outlook.
Now the question comes to how you can convert NST files into PST format. Actually, converting NST files into PST isn’t as easy as it sounds. It has some criticism as it isn’t readable. We would recommend using the Regain OST Converter software for this purpose. Follow the steps as follows:
- Step 1. First, on your device, open the directory of the NST files (we have described how to find the location of NST files on your desktop. Check out the above phases).
- Step 2. After locating it, click the right button on the NST file and click on the “properties” option.
- Step 3. Then, from the ‘General’ tab, change the .NST extension to the .OST. That’s all.
After that, you need to download and configure the OST file on your device. Then, with the help of this professional software, you can easily convert the .OST formatted files into .PST and open them in Outlook.
In this way, you can open NST files in your Outlook. It’s an indirect way, but probably the easiest one as far as we know from our research.
