Microsoft Outlook is a robust business email client widely used by organizations and enterprises running on-premises Exchange Server or Office 365. When you add an Exchange mailbox profile in Outlook, the profile is set up in Cached Exchange Mode by default. In addition, an Outlook data file (OST) is created, which stores a synchronized copy of mailbox items to provide offline access to your mail items even when the network is unavailable, or the server is offline for a seamless user experience.<\/p>

Outlook also stores Online Address Books or OAB files on the local machine—a downloadable address list similar to Global Address List (GAL) available on the Exchange Server.<\/p>
