OST (Office Storage Table) is a kind of format that is used for storing email messages on local servers so that network users can change OST files in offline mode and synchronize them with the Exchange Server after going online. PST files, on the contrary, are stored on local servers and local disks. For this reason, many users consider them to be less vulnerable to network breakdowns, corruption and malware attacks, than OST files. There is a number of user friendly and effective conversion utilities, which do not require any technical skills on users' side.
