In this era of advanced technology, email is defined as one of the most popular and integral communication tools. Among the extensive options, Microsoft Outlook is one of the most widely demanded email client application. For all its email-based communication, it works in complete conjunction with the Exchange Server. This powerful server-side application offers brilliant email-based collaborative communication by allowing an individual to access data conveniently from anywhere. The distinct feature of the Exchange Server is its Online Storage facility owing to which you can easily salvage complete mailbox data and can share as well.<\/p>\n
In MS Outlook, users usually encounter two types of storage files\u2014OST and PST. OST is a perfect option when a user is working in the offline mode and PST when working in online mode.
