If you have been using Outlook as your email client, then you probably have a very clear idea how troublesome OST format can be. The benefit of this format is that it saves mail content like emails, calendars, tasks, drafts etc. offline. The con of this format is that it is very fragile, and is easily damaged.

OST is Outlook’s format which is only meant for offline usage. You can access your mails, change your drafts, and upgrade your calendar offline with the help of this format. Outlook with the help of this format allows you to make changes but makes it hard to upgrade your mailbox once the system is online. This happens because OST does not work directly with Outlook. It can be imported only through PST format.

SO, in a nutshell, there are two problems with OST format. First, it does not work directly with Outlook, and hence, has to rely on MS Exchange server to be imported in Outlook. Second, it is very fragile and easily damaged. What is the solution to these problems? The answer is OST Extractor Pro.
