Free OST to PST Converter Features

Offline OST to PST Conversion

The OST to PST Converter exports OST to PST in offline mode. It accesses all OST files on the system without the original Exchange profiles or an Exchange Server connection and then converts to PST. Even orphaned or damaged OST files can be converted to PST.

Search & locate OST files

The Search feature of this free tool helps to find all the OST files available on the system. For conversion, you can just select the required file from the list displayed by the tool. This basic feature is for all users

Complete Preview for FREE

This free OST to PST Converter is like an open source tool when it comes to the preview feature. The entire OST mailbox data—emails, contacts, calendar, etc.— can be previewed. And in the case of damaged OST files, all recoverable items are displayed for preview.

Saving to Exchange, Office 365, Thunderbird, & Gmail

This freeware utility can be upgraded to get many advanced OST saving options like Exchange Server, Office 365, MBOX, and web mails. So this utility is suitable for Exchange administrators as well as home users.

Analyze the OST File Content

This tool provides four types of OST File Analysis Reports for free: Total item types on the OST file, Mail flow density by date/users, and interaction between any two different users. The content of the entire OST file or selected mailbox folders can be analyzed this way.

Search, find, & save emails

You can fetch essential emails from even from very large OST files, just by providing a few search criteria like From, To, Subject, Date range, or Attachments. The items then can be previewed and saved to the desired formats/destinations.

Convert OST to PST Free

Export 25 items free from each folder of OST to Outlook (PST), Outlook Express (DBX), MSG/EML, TXT, HTML/MHTML formats. And for OST files up to 500 MB size, we offer free conversion from OST to MBOX (Thunderbird), DBX (Outlook Express), PDF (Adobe Reader), EML/MSG, RTF/TXT, HTML/MHTML, & PST (Outlook) formats.

Export OST to PST in Outlook 2003 & later

This free tool exports OST to PST of Outlook 2016, Outlook 2013, Outlook 2010, Outlook 2007, & Outlook 2003 versions.
You simply can import the PST file to any of these
versions of Outlook.

Can I back up my mailbox without Exchange administrator’s involvement?

The OST to PST Converter is designed keeping the end users in mind. You can back up your mailbox to PST file on your end without any involvement of Exchange administrators.

I am using Thunderbird on my personal system as it is free. Can I export my official emails from my Exchange account to Thunderbird using this tool? I don’t want to disturb my Exchange administrators for this simple task.

You can export your official emails from OST files to MBOX format using this tool. You can perform it yourself without any help from Exchange administrators (however, make sure that your company policy allows you to do this).

OST files are on client systems. But why this tool has options to save OST files to Exchange Server, Office 365, etc.?

Exchange administrators can use this tool after Exchange disasters to restore user mailboxes to a live Exchange Server or Office 365. Only thing is that they have to collect OST files from the client machines.

I had a huge-sized OST data for migration. On my colleague advice, I tried this utility. It saved my OST data into small-sized multiple PST files. Apart from this, I suffered no data loss in the whole process. Thanks to the efficient team for this software.

After using some given manual methods and instruction on various blogs, I lost all hopes to recover my deleted mailbox data. But thanks to my friend, who suggested me to use this OST to PST converter software, It helps me not just to recover my OST files but also allows me to retrieve meta properties of emails. Thanks a lot.

The manual Scanpst.exe solution failed to provide the successful recovery. I googled and found this outstanding PST conversion tool. The tool recovered my data within minutes and saved it as a new PST file easily. Hats off to the brilliantly programmed tool.

I advised this tool to my friend with a non-technical background. He recovered all the lost OST data himself using OST to PST freeware. The swift and accurate conversion impressed him a lot. Great solution for any Outlook user with corruption issues.
