Microsoft Outlook offline files (OST) are the replica of Exchange Server mailbox folders on local machines. In the offline (cached Exchange) mode, Outlook saves all the Exchange mailbox data locally in the OST file. The OST file thus contains all your mail items in an offline mode on your hard drive. This way it provides an efficient medium of accessing the Exchange Server mailbox folders in the event of server crashes or poor Internet connection. Although the OST file can’t be affected by disturbances in the Exchange Server, there are situations that make the mail items inaccessible and can affect your routine business operations.
