How I Saved My Offline Outlook Emails in a Single Web Page Format Using OST to MHTML Converter

Author: Archer Gyles

Hello everyone! Today, I am sharing my own experience with the OST file. So, a few days ago, my friend faced an error when opening the OST file, which showed that the file was corrupt. We don’t know what actually happened, so we are searching for the OST file and why it was corrupted. Maybe you also face this issue, and you also panic like me, because the OST file stores our local copy of the mailbox, which allows us to work offline, and when it reconnects with the server, it will automatically update. When it is corrupt or inaccessible, users cannot open or read it.

So, today I am telling what I do and what actually happened, and if you face this issue, what can you do to save your Outlook emails?

Reasons for Corrupting the OST file

There are several reasons for corrupting the OST file. My OST file became corrupted due to a sudden system shutdown. Once, my system shut down unexpectedly while Outlook was syncing or accessing my OST file. Several reasons can cause a corrupt OST file.

  • Outlook or Windows Crash: Crashes caused by software conflicts, outdated add-ins, or faulty updates can damage the OST file structure.

  • Hard Drive or Storage Failure: Bad sectors, physical damage, or disk errors on the drive where the OST file is stored can cause corruption.

  • Synchronization Issues with Exchange Server: If Outlook fails to sync properly with the Exchange Server (due to network instability, large mailbox size, or server timeout), incomplete synchronization can cause corruption.

  • Virus or Malware Attack: Malware infections can modify or delete portions of the OST file data, making it inaccessible.

  • Oversized OST File: When the OST file grows too large (especially over 50 GB in newer Outlook versions), performance issues and corruption risks increase.

What I do After That

After knowing those reasons, I searched how I saved my important OST file, then I discovered the MHTML and HTML format for saving the OST file. I chose the MHTML format for saving my OST file because MHTML is an advanced version of the HTML format, and we can’t recover or save images in HTML format. That’s why I chose the MHTML format, because I want to recover my Outlook emails and images as well.

How to Convert OST to MHTML Format

After multiple searches, I found a professional and advanced tool for converting OST to MHTML format, which is FixVare OST to MHTML Converter. I searched for how to convert OST to MHTML, and Google suggested this tool. Then, I reviewed it, and most reviews are positive. Then I select.it

Which Steps do I follow to convert OST to MHTML?

I am a non-technical user; I didn’t know how to convert OST to MHTML, but shockingly, this tool offers the best and easiest way to convert OST to MHTML format rather than other converters.

You can also convert OST to MHTML format by following these steps:

  1. Install & Launch Tool –

    Download and open the FixVare OST to MHTML Converter on your system.

  2. Add OST Files –

    Click "Add File" or "Add Folder" to load one or multiple OST files for conversion.

  3. Preview Mailbox Data –

    The software displays a preview of all emails, attachments, and folders before export.

  4. Choose MHTML Format –

    From the available saving options, select MHTML as the desired output format.

  5. Set Destination Path –

    Browse and choose the location where you want to save the converted MHTML files.

  6. Start Conversion –

    Click "Convert" to begin the process and, once completed, access your MHTML files in any web browser.

I tried the demo version first, but after getting the results of converting, I chose it as a permanent backup plan for converting and saving my OST file. Not only because of its steps, but also features are amazing, like offering a preview of the mailbox before converting the OST files, maintaining folder hierarchy, supporting bulk conversion (convert multiple OST files at once), compatible with all versions of Windows and MS Outlook, unlimited license validity, etc.

Manual Method

Before this, I used the manual method as well, but it did not give me a satisfactory result. I chose it because many of my friends told me about it. But they are technical users; they have technical knowledge and technical experience, but my friend and I don’t have it. After watching videos, I tried it and successfully converted the OST to the MHTML format. After I go to open it, my attachments are not converted, and I get some emails, and every email. I convert one-by-one OST files because it does not support bulk conversion. After seeing a lot, I decided to convert the OST file to MHTML format using converter software.

Conclusion

If you're facing the same issue as me, like corrupted, inaccessible, and even orphaned OST files. Try to go with a professional tool like FixVare OST to MHTML Converter. Because if you go to the manual method, you don’t get satisfactory results, and the manual process is a time-consuming method because it does not support bulk conversion, and it also has multiple issues.
