Overview

The Outlook Personal Storage file extension and the NST file extension have no difference. The way the data is kept is somewhat similar to Outlook Personal Storage. Thanks to the plugin, users of Lotus Notes will be able to access them from Microsoft Outlook. Posting a non-storage format (NST) file to an IBM Notes account allows one to access it offline. Microsoft Outlook is in fact in charge of creating these automatically. It stores emails, messages, contacts, and a great lot more.

Category

It comes under the binary data file category.

Supportive Apps

All NST files support Outlook 2013 and the latest versions.

Developer

It is Microsoft behind the development of NST.

MIME Types

It is one MIME type- application/vnd.outlook-notes

Location

The location of NST is depended on the type of Windows version you are using.

In Windows XP, the location of the Extension is-

C:\Documents and Settings\%username%\LocalSettings\Application Data\Microsoft\Outlook\

In Windows 7, 8, and 10, the location of the file extension is-

C:\Users\%username%\AppData\Local\Microsoft\Outlook\

Since NST is automatically generated in MS Outlook, it has no direct way to open it. NST files are like personal storage files. If you want to open easily without data corruption, a third app can be helpful.
