Backup Outlook Emails from OST as PST When Exchange Server Crashed

An OST file provides a secure medium to work offline when Exchange Cached mode is enabled. The limitation associated with these files is that they sometimes turn inaccessible and the major reason behind this is synchronization failure. There are many reasons that contribute to OST synch failure and these include unreliable internet connection, inappropriate functionality of Server and many more.

It is a good practice to backup OST emails as PST file – when Exchange Server crashed or when sync procedure fails. Though, there are many procedures available to backup OST files data to PST but they are only applicable in live Exchange environment.

During Server crashed instance, it is important to find out some reliable medium that can handle orphaned OST files and convert them to PST so that they can independently be accessed in MS Outlook interface. Since Microsoft does not provide any inbuilt resource to convert these Offline folders to Personal Storage Tables, the conversion task can be accomplished using some third party tool.

There are several points that must be considered while recover OST email to PST and these considerations are:

Ensure if the OST file exists in healthy state and allows access.
The format of the file; whether it is ANSI or Unicode type.
