High corruption in Exchange is a real downtime in organization. Pre understanding of difference between OST and PST, help you in many ways.
• What are Outlook PST Files? PST or personal Storage Table are created in Outlook with components like calendars, tasks, journals, notes, to do list, tasks etc. stored locally on PC. These PST files are the storage location on hard disk or a Server but not on Exchange Server. .pst files are created when Outlook is used in order to manage email. PST can be created in Exchange environment, however, Microsoft do not recommend this because PST are considered unstable and can make PC crash and once this happens you are likely to lose all your Emails in Outlook. In Exchange Server environment, if you are using PST, it removes emails (from Exchange Server) and then store PST files locally.
•What are Outlook OST Files? OST or Offline Storage File is a copy of mailbox stored on Exchange Server. It contains data like calendars, journals, notes to do list, contacts, Deleted Items, Inbox data, which gets synchronized to OST file and gets saved on hard drive of users. It allows you to work offline as you do in online mode and in conjunction with the Exchange during synchronization.OST files is copy of data in Exchange. Without network or slow internet connection, .ost files work for you. You can make any changes in .ost files when you are offline, you can send messages, you can move items in offline inbox, read offline folders etc.
These OST files cause damage so it is important to convert OST files to PST files so that these important OST data can be used in PST format of Outlook. Corruption makes OST files out of use, but to make them usable, use outside software.
