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.

This is a very excellent solution that lets you move OST files into Outlook PST files with entire email properties such as :- to/cc/bcc/from/sent/subject and other information. Importantly it performs migration without losing or tampering the original OST content.
