Outlook is one of the most used Desktop email clients that is used to manage multiple E-Mail accounts from the single interface. It provides a lot of features to the user for email management. Internally it stores the data of those emails into the OST file format when the user connected with Exchange Server with Cached mode enabled. OST file is also created when a user configures IMAP accounts in Outlook 2013 or above versions.
