Most Efficient PST Viewer Software in 2025

[Henry Walker]

There are both manual and professional methods to open PST files without using MS Outlook. Many users look for such solutions either because they don’t have Outlook installed, are using devices that don’t support it, or want to avoid the cost and complexity associated with the software.
Manual Methods:
If you have Outlook installed and only want to share or access PST file content in another format, you can save individual emails in HTML or TXT format.
To convert to HTML:

1. Open Outlook, select the email.
   
2. Go to File > Save As.
   
3. Choose HTML (.html) and click Save.
   

To convert to TXT:

1. Open Outlook and select the required emails.
   
2. Click File > Save As.
   
3. Choose TXT (.txt) and hit Save.
   

While these methods work, they come with major drawbacks:

• Require MS Outlook installed on the system.
  
• Not suitable for opening corrupt PST files.
  
• Time-consuming and limited to email content only.
  
• Increased risk of data loss or misinterpretation.
