OST file is an offline folder file in MS Outlook represented with an OST extension. Now users can easily work offline while the server automatically synchronizes changes with Exchange Server till the next time the user reconnects. The ability to work offline is useful in environments where the network is limited or unreliable. Thus, the creation of an OST file allows users to work in a situation of server downtime as well.

While working in an offline mode, Microsoft Outlook generates an exact copy of the user mailbox on Exchange Server named as offline folders with OST file extension. A file, i.e. The above mentioned file; is saved locally on the desktop which is named as an Offline folder file. The exchange contains the exact replica of the folders of an individual user. Any type of modification you perform offline will automatically be synchronized when connected to Exchange Server.

By making use of the send/receive command, you can perform send or receive functions and copy the changes which were made while working offline. During this process, permanently deleted items get removed from the Exchange’s Server copy also.
