How to repair Outlook emails using OST to PST Converter

Outlook is still the main email client for Windows, mainly in the business sector, but the app crashes often, resulting in email loss. But it’s important to know that you can retrieve the information using an OST to PST converter.

If you have a Microsoft account, it’s free to use but it’s also available together with Microsoft 365 if you want the desktop version.

However, Outlook is not always the most comfortable app to work with and it’s riddled with all sorts of bugs that prevent you from using it or accessing your Inbox folder.

We have plenty of guides to fix the program. For instance, you can learn how to recover deleted/archived Outlook messages if you’re having such problems.

But lately, we discovered OST to PST Converter, an app and online tool that helps you repair your Inbox by converting the data storage files in Outlook.

If you use Microsoft Exchange Server or use IMAP mail protocol in Microsoft Outlook, OST files are created on the disk imperceptibly for you.

An OST file is simply a buffer between the mail server and the local Outlook. Generally, you would never need to know about the existence of this file on your computer.

But sometimes there is trouble and only converting OST to PST will help you save your e-mails, contacts, appointments, notes, files, and others from Microsoft Outlook.

Let’s look at some situations when you might urgently need an OST to PST converter tool:

  1. Microsoft Exchange Server Enterprise is unavailable or not working.
  2. Corporate Windows Domain Controller is unavailable or not working. As a result, you cannot log in to the corporate network.
  3. The corporate network is not available.
  4. Gmail/Outlook/Hotmail and/or other mail server is unavailable or cannot be authorized, or the account has been deleted or the account has been hacked.
  5. You were fired from your job and deprived of access to corporate mail.
  6. Synchronization with the mail server via IMAP fails.

In these or other similar situations, you have a local version of the emails and contacts stored in the OST file.

But Microsoft Outlook does not allow you to just open this file without authorization on the mail server or Windows Domain Controller.

In all these cases, the conversion of OST to PST will allow you to open your data in Outlook and continue using them.

How can the Online / Offline OST to PST Converter help you?

As we’ve mentioned above, the OST and PST files are Outlook’s data storage files. The OST files store the offline data while the PST covers the information stored on your local disk.

When you can’t access your emails, you basically can’t access these databases even if the messages are still there.

That’s where this OST to PST Converter ingenious tool comes into play that helps you convert a possibly damaged OST file into PST, MSG, EML, VCF, and TXT files.

Basically, with this OST PST conversion tool, you recover all the content from your Outlook, including the messages, contact details, and more, even if they are encrypted.

This tool can be used online, but the desktop version has no limit for the number of OST files, or their size and you don’t have to upload your database on the web.

Long story short, how to convert an OST to PST file and how to repair your Outlook emails easily.
