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.

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.

Free tools are the best, if available. But for OST to PST conversion, I think, this one is the best choice as no free options are available.

Kernel for OST Recovery Software is the most effective email recovery software as I was able to conduct the entire ost file recovery operation in a very short time. The most remarkable aspect of the software was Its ability to restore the OST file and providing option to export it to email servers, web emails and Office 365 platform. I strongly recommend this tool to try at least once.
