Microsoft Outlook is one of the most widely used email clients. This desktop application provides the facility to manage email, calendar, tasks, and contacts. It stores user data locally on their computer, allowing users to access their email profile items even in offline mode.
When you set up Outlook profile with an Exchange, IMAP, or Office 365 account, Outlook creates an Offline Storage Table (OST) file.
An OST file is a local copy of your mailbox data that is synced with the mail server. You can read and write emails, manage calendars and access other Outlook features from OST even in the absence of the internet.
Once you reconnect to the mail server, all the changes made offline inside OST files are automatically synced with the mail server data.
