If you want to learn more about Exchange Cache Mode and Online Mode, the article helps you. These are two different modes of operation for MS Outlook when connected to a Microsoft Exchange Server.<\/p>\n
Exchange Cache Mode:<\/strong><\/p>\n In this mode, Outlook creates a local copy of the mailbox. It means, MS Outlook with integration of MS Exchange creates the copy of online mailbox data in an offline folder that we call OST or Offline Storage Table. It keeps emails, calendar, contacts, notes, events, tasks, journal, etc. The file synchronizes with the Exchange Server periodically.<\/p>\n When Outlook creates an offline file or OST, it allows users to work offline. Changes made during offline transfer to the Exchange Server with automatic synchronization as the connection re-establishes.<\/p>\n The platform improves performance because accessing of mailbox data locally is often faster than retrieving data from the server.\u00a0 With offline access, it improves workflow. Since caching of mailbox data locally, it reduces the load on the Exchange Server, especially working with limited bandwidth.<\/p>\n Online Mode:<\/strong><\/p>\n In this mode, Outlook allows users to access data from the Exchange Server directly without the need of a local cache. It indicates dependence of Outlook entirely on the server for accessing and managing mailbox items. In this mode, it is important to have a stable internet connection to access mailbox data.<\/p>\n One of the greatest benefits of online mode is real-time access of data. They can access the most recent mailbox data. It helps to maintain the speed of the system by requiring less disk space. Admin team prefers online mode to offline mode for centralized management of data.<\/p>\n
