Microsoft Outlook stores offline mailbox data in OST (Offline Storage Table) format. While useful for offline access, OST files can become inaccessible due to account deletion, corruption, or synchronization issues. In such cases, converting OST to MHTML (MIME HTML) format offers a practical way to view mailbox data via any browser.
In this guide, we’ll explore how to convert OST to MHTML and why using a professional solution like the Mydigisoft OST to PST Converter Tool is the most reliable way. This post is designed for IT professionals, general users, and email administrators across regions like the USA, UK, UAE, Saudi Arabia, and South East Asia.
Why Convert OST to MHTML?
Here are several reasons why users prefer to transfer OST to MHTML:
-
Web-based Viewing: MHTML files can be opened in any browser without Outlook.
-
Preserves Formatting: Maintains original formatting, hyperlinks, and embedded items.
-
Simplified Archiving: Easier for compliance and documentation purposes.
-
Accessibility: Ideal for sharing mailbox content with non-Outlook users.
Challenges in Manual Conversion
There’s no direct method in Outlook to convert an OST file to MHTML format. While you can manually save individual emails as MHTML, bulk conversion is not feasible. Moreover, OST files linked to an inactive profile or server can’t be accessed manually, leading to data loss risks.
Hence, the best approach is to use a reliable third-party tool like Mydigisoft OST to PST Converter Tool.
