OST File Type


An OST file extension is a kind of file that allows users to save their email data and other information. It is also known as the "Offline Outlook Folder File" and takes up less space than the PST file. The OST File extension has been around since July 2000, but it only recently became popular because of its usefulness for those who rely heavily on Microsoft Outlook software. One of the main benefits about an offline OST is that it offers additional storage space for those who rely heavily on Microsoft's Hotmail service. An Outlook Offline Folder File folder allows users to store deleted emails, conversations, and attachments in a separate folder which makes it easier to recover data when necessary.
