If an offline folder file or OST file becomes damaged or corrupt, you could hope to recover all the data by creating a new OST file from the original mailbox stored on the Microsoft Exchange Server. Recovering data from an OST file, if an Exchange server becomes corrupted, on the other hand, is fairly challenging. We will look at how one can simplify this process, especially by using third-party tools.
Most Outlook users with email accounts on a Microsoft Exchange Server believe that the data in their accounts are safe as the system administrator usually has a backup and recovery mechanism in place. However, it is not unusual to find that there have been situations wherein the Exchange server has become corrupted or backups have been found to be damaged and the only source to carry out an Exchange recovery has been the offline folder file or OST file. However, trying to recover all the Exchange data from these OST files is not straightforward and it can be fairly challenging to recover all the data in the same structure as they were in the original mailbox. Fortunately, there are now fairly sophisticated tools that allow you to carry out this process very easily.
DataNumen Exchange Recovery from DataNumen is a third-party tool that specializes in recovering data from orphaned OST files. When Microsoft Exchange Server becomes corrupted, the mailbox on the server is also lost leaving behind an orphaned OST file. There is almost no way that an orphaned OST file can be accessed easily. Therefore, the first step in carrying out an Exchange recovery is recovering the data from an orphaned OST file.
DataNumen Exchange Recovery supports integration with Windows Explorer. You can thus very easily find and select the OST file that you would like to repair. With just a click of the ‘Repair’ button, you can start the restoration process on a large number of files. This tool works across many formats of Exchange, leaving you with one less thing to worry about. Finally, DataNumen Exchange Recovery can recover almost every type of Exchange item including all email messages, appointments and reminders, meeting requests, contacts, task items, notes and so on. In fact, it can even recover attachments and embedded objects along with the items that they are associated with.
It is always difficult to carry out an Exchange Recovery from large OST files because of their size. But, DataNumen Exchange Recovery can actually recover data from very large OST files – as large as 16 million TB! To top it all, this tool will save all the recovered items in a personal folder file or PST file that is also compatible across all formats from Outlook 97 to Outlook 2002 and Outlook 2003 to Outlook 2010.
DataNumen Exchange Recovery requires that Microsoft Outlook be installed on the computer where the OST files are located and this obviously means that it should not be installed on the Exchange server. Install a copy of DataNumen Exchange Recovery on a desktop computer that is not being used as a server, copy as many OST files as you can to this local machine and then run the tool to restore data from the orphaned OST files into PST files. Since Outlook can easily access PST files, you have now ensured that all the data from the original mailbox is now available in Outlook and you can just copy all this data into the new mailboxes on the Exchange Server.
