How to Convert OST to HTML files with Outlook Emails?


If you need to Convert OST to HTML files with Outlook Emails, there are many ways to do it. But it is difficult to find the best way among all of them. So, for your convenience we are here with this article. Here we will show you the safest and smartest way to convert OST emails to HTML files. Let’s start reading.

Understanding the File Formats: OST and HTML

Before we dive into the conversion process, it’s important to understand which two formats you’re working with: OST (Offline Storage Table) and HTML (Hypertext Markup Language).

OST File: – OST is a file type that Microsoft Outlook uses to store a local copy of your email profile mailbox data. This file contains emails, calendars, contacts, and other important items.

OST files provide offline access to your data, but are not easily accessible outside of Outlook. Also, it is difficult to share and transfer information from OST files.

HTML: – HTML is a file format that can store various information and helps display content on the web. When you convert an email to HTML, it makes it possible to read the email through a web browser just like a normal web page. It fully supports keeping emails with the original structure and formatting.

HTML files are lightweight, portable and easily accessible without the need for Outlook. This makes it a versatile option for storing or sharing emails across different platforms.
