When users set up Exchange, Office 365, or IMAP accounts in Microsoft Outlook, the program saves mailbox data as OST (Offline Storage Table) files. These files let people read emails while they aren't connected to the Internet, but they are very closely tied to the Outlook profile and Exchange server. Users typically hunt for ways to change OST files into formats that are easier to open because they can't open them on their own. HTML is one of these formats that makes it easy to see emails in any web browser on any version of Windows. This post talks about free ways to Toolsbaer OST to HTML Conversion format and what they can't do.

Why do you need to change OST files to HTML?

HTML (HyperText Markup Language) is a file type that works on all Windows computers and can be opened in any web browser, such as Chrome, Edge, or Firefox. Changing OST files to HTML helps people:

Read Outlook emails without having Outlook installed

Read emails on any version of Windows

Make backups of your emails that are easy to read and share.

Keep the original formatting and presentation of the email

Keep emails in a format that is easy to open and move around.

Because Microsoft doesn't have a simple way to export OST to HTML, customers have to do it by hand.

Free Method 1: Use Outlook to Export OST Emails to HTML

Using Microsoft Outlook's "Save As" feature is the most common free way to do this.

Follow these steps:

Open Microsoft Outlook with the same account that made the OST file.

Check that the OST file is completely in sync with the Exchange server.

Open the email you want to change.

Select Save As from the File menu.

Select HTML (*.html) as the kind of file to save.

Choose a folder to save the email in.

This method stores each email as an HTML file that can be opened in any web browser.

Limitations:

You can only save one email at a time.

Needs an active Outlook account

Not good for bulk conversion

Takes a long time for big mailboxes

Method 2: Use Windows File System's drag-and-drop feature for free.

Another free way is to drag emails from Outlook to a folder.

Steps:

Open Outlook and choose the emails you want.

On your Windows computer, drag and drop the emails you want to a folder.

You can save emails as .msg files.

In Outlook, open each .message file and choose Save As > HTML.

Limitations:

Requires more manual steps

Not good for sending a lot of emails

Needs to have Outlook installed

A lot of chances for mistakes by people

Indirect Method 3: Print to HTML from a browser

Some people open emails and print them to virtual printers that handle HTML, while others store them through their browsers.

Steps:

In Outlook, open an email.

Click Print and choose a virtual printer that can print HTML or web pages.

Save the output as an HTML file.

Limitations:

Inconsistent formatting

Attachments are not saved correctly

Needs tools from other companies

Free methods for converting OST to HTML have certain problems.

Free approaches may work for some needs, but they have a lot of problems:

Can't convert the whole OST mailbox at once

Do not support OST files that are broken or missing

Need an active connection to Outlook and Exchange

Risk of not getting emails or attachments

Very time-consuming for business use

For large or business mailboxes, these constraints make free methods not work.

OST Exporter is a reliable alternative.

If you need to convert a lot of files at once or want to make sure that all of your OST files are converted to HTML format, you should hire a professional. OST Migration lets users export OST emails directly to HTML format without using Outlook or Exchange. It works with all versions of Windows, from Windows 11 to Windows 10 to Windows 8.1 to Windows 8 to Windows 7.

It keeps the folder hierarchy intact, makes sure all data is correct, and lets you choose which files to export.

Conclusion

If you want to read Outlook emails on any version of Windows without having to install Outlook, converting OST files to HTML is a good way to do so. You can use Outlook's Save As option to transfer single emails for free, but these approaches don't work for mass or professional purposes. People who have to deal with big OST files or need correct conversion should think about a solid solution. Before choosing the proper approach, Toolsbaer suggests looking at the size of the mailbox and how easy it is to get to the data. Professional instruments give the most reliable results for safe, quick, and easy conversion.

Microsoft Outlook is used by a lot of people and businesses to keep track of their emails, calendars, contacts, and other mailbox data. There are two main types of files that Outlook uses to store mailbox data: PST (Personal Storage Table) and OST (Offline Storage Table). It's easy to move and manage PST files, but OST files are linked to the Exchange or IMAP account that made them.
