How to convert an inaccessible OST file to PST format

 

Stellar Converter for OST is an innovative software for those who want to convert their inaccessible OST files into Outlook importable PST file without any file size limit. The software helps you securely export your mailbox items such as emails, contacts, calendar, notes, deleted emails, etc. to a different Outlook account with up to 100% precision and data integrity.

Although Outlook, Exchange, and Office 365 have an option to export the mailbox items into Outlook importable PST file format, there are times when your profile may get corrupt or become inaccessible.

Sometimes, your profile may be deleted, disabled, or your user account is denied access to the mailbox exchange server. This may happen due to virus or malware infection, MS Outlook app issue, incompatible Outlook add-ins, etc.

In such conditions, you can neither access the mail client nor export your mailbox items stored in orphaned OST file to Outlook PST. That's where a software tool such as Stellar Converter for OST comes into the picture.

User Experience
With powerful features and capabilities, this OST to PST converter tool may sound like a complex tool to use. However, it's one of the most easy to use and neatly designed software tool to convert OST files in Outlook importable PSTs and other formats.

The installation was quick, similar to installing any other software. I installed the corporate edition of Stellar Converter for OST.

You don't need to change any settings in the PC or require additional permission other than administrator access.

After installation, I launched the software. The user interface of the software is inspired by MS Outlook app and thus, you will find the software quite familiar and easy to use. The main screen opens with a dialog box where you can browse and Find the OST file, and that is what I did.

I added my OST file and clicked 'Convert' button. But if you don't remember where your OST file(s) is located, use the 'Find'' button.

After the scan, the software also recovered deleted mail items, which are marked with red color. I was able to preview all the mailbox items such as emails, contacts, calendar, etc. including the deleted emails.

The software also displays the attachments. You can see the attachment names and file type but can't preview them unless you activate the software, export the mailbox items to PST or other format, and import the converted OST to your email account.

NOTE: Post OST file scan, make sure to save the scan information. This will help you avoid rescanning the OST file after software activation.

After the scan and preview, I chose to save a few mailbox items from the scanned OST to a PST file, which I later imported into my new Outlook profile.

However, the software also lets you export the scanned OST mailbox items directly to an Outlook profile. (Technician edition only).

I selected the important mail items, email folders from the scan results, and clicked 'Save Converted File'.

At this point, the software displayed a message asking to close the MS Outlook app.

So make sure to close MS Outlook before saving the converted OST file to other formats.

After closing MS Outlook, I clicked 'Save Converted File' again and chose PST from the option. With Technician edition, you can also choose to 'Split and Save PST' or 'Compact and Save PST' option under 'Advanced Options'. This helps prevent PST file corruption due to oversizing.

Finally, selected a destination location on the drive and clicked 'OK' to save the PST file.
