Outlook OST (Offline Storage Table) allows you to work in two modes: online and offline. This gives the user the advantage of not losing his work rhythm. Outlook saves information in these two modes as an OST file. These offline OST emails are synchronized with the Exchange server when the system connects to the internet. Sending and receiving OST emails is an important aspect of the Outlook application. You can also import the Outlook OST file into Outlook 2019, 2010, 2013, and 2016.
