A personal storage table (PST) file is an efficient solution for data storage, especially for people struggling to keep track of their emails, contacts, and communications. Not only do PST files offer a safe and reliable means of storing sensitive data, but they also serve as an email data backup system for Microsoft Outlook and offer offline access.

Nowadays, more and more people are turning to free email clients instead of paying for Microsoft Outlook. This is a great idea until you want to open PST files without Outlook. Many online email clients (and standalone desktop clients) do not support Outlook OST and PST files.

Luckily, several excellent tools can help you view .pst files without Outlook. This guide provides eight simple ways to open PST file without Outlook:

1. CoolUtils Outlook Viewer

CoolUtils Outlook Viewer allows you to view PST, OST, and even an MSG file format without Microsoft Outlook. This free tool is easy to use and allows you to open both PST and OST files as well as sort files and generate reports so you know what emails you have. Files from Outlook 2010, 2013 and 2016 are supported. This free viewer also allows you to convert your PST and EML emails to use with other email clients such as Thunderbird.

Coolutils app is the easiest to use of all of the tools. All you do is install it and your PST files are automatically loaded so you can immediately view them. For some additional cost, it offers a good Outlook pst file converter if you need to save emails as PDF or DOC files.

2. Google GAMMO Tool

The Google GAMMO Tool

is an interesting way to open PST file without Outlook. Google developed this free tool to migrate your emails within a PST file to Gmail. This tool allows you to import mail, calendars, and contacts into a Gmail account as well as include only the folders you wish to convert. 

There is also a feature for administrators to run this tool from the command line for mass email migrations. Note that this tool requires a Gmail account. However, its major downside is that it will only migrate your emails to Gmail.

The simple two-step process of accessing the PST file content begins with downloading and running the tool and selecting the location of your PST file.
