Nowadays more and more people are turning to free email clients on instead of paying for Microsoft Outlook. This is a great idea, until you want to open an old .pst file without Outlook. Many online email clients (and standalone desktop clients) do not support Outlook OST and PST files.
There are several excellent tools that will help you to open .pst files without Outlook. Below are five of these tools:
1. CoolUtils Outlook Viewer
CoolUtils Outlook Viewer allows you to view PST and OST files without 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 view PST files without Outlook. This tool is free and was developed by Google to migrate your emails within a PST file to Gmail. This tool allows you to import mail, calendars and contacts into Google mail 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 migrations of email. You do need a Google account to use this tool. The only downside to this tool is it will only migrate your emails to Gmail.
The simple two-step process begins with downloading and running the tool and selecting the location of your PST files.
Once you locate your files, you can choose which elements of the PST file to migrate such as your calendar, contacts or email messages and it allows you to include a specific date range if you are looking to migrate specific emails.
3. MS Outlook PST Viewer
Forensicsware MS Outlook PST Viewer allows you to view PST without Outlook. This application will allow you to view all Outlook items such as contacts, calendar items, tasks, etc. This application also supports large and corrupted PST files that may not be able to be opened using the Microsoft Outlook client. There are two version of MS Outlook PST Viewer, free and PRO. The free version has limited features.

4. OST PST Viewer
The OST PST Viewer is an application that allows you to view PST files without Outlook by using an Outlook-type interface. The free version of this application allows you to open, view and search PST files without Outlook. The PRO version has many more features, but at a cost.
